4HH Engine Problems: Boxer and Jumper 2.2 HDi

The 4HH is the engine code of the 2.2 HDi 130 in the Peugeot Boxer and the Citroën Jumper, which Citroën sells as the Relay in the United Kingdom and Ireland. It is a 2,198 cc four-cylinder common-rail diesel with 96 kW (130 hp), and it arrived with the Euro 5 engines in July 2011. Peugeot describes the 2.2 HDi as an engine from the cooperation between Ford and PSA Peugeot Citroën, developed for commercial vehicles. The French magazine L'argus writes that Ford designed it. The 4HG (110 hp) and the 4HJ (150 hp) are the other Euro 5 versions of the 2.2 HDi.

Few problems with this engine appear in official records. The UK recall data hold one injector recall for vans built from September 2014 to January 2015. L'argus also reported piston damage on the earlier Euro 4 versions built up to July 2008. Base the choice between repair and replacement on a diagnosis of your own engine.

Symptoms and First Checks

Start from what the van does. The section named in brackets gives the full test and the documents behind it.

The engine does not start or stalls, and the van was built from September 2014 to January 2015. Check for an open recall (Injectors and the 2015 Recall).
The engine loses power, knocks, runs on three cylinders or smokes. Stop driving, then measure the compression of all four cylinders and test the injectors before anyone replaces parts (Knocking, Smoke and Piston Damage).
Noise and vibration come from the timing end of the engine, the charging warning lamp comes on, or an auxiliary belt is damaged or comes off. Check the crankshaft pulley (Crankshaft Pulley).
The engine does not start, stalls or runs in limp mode, and the diagnostic tool loses contact with the engine control unit. Check the power supply, the earth connections and the wiring before you replace the unit (Engine Control Unit).
The turbocharger fails, or the engine loses boost pressure. Find the cause before you fit a new turbocharger (Turbocharger).
A rattle comes from the timing end of the engine. Check the timing chain and its tensioner (Timing Chain).
The engine loses power and a warning lamp comes on after short trips. Check the particulate filter (Particulate Filter).

What the 4HH Is

Peugeot's press releases for the Boxer give these facts for the 2.2 HDi:

Specification	2.2 HDi
Displacement	2,198 cc, four cylinders in line
Bore and stroke	86.0 × 94.6 mm
Construction	Cast-iron block, aluminium cylinder head, 16 valves, two overhead camshafts
Timing drive	Chain. For the Euro 5 engines, Peugeot states a timing chain that does not require replacement.
Fuel system	Common rail. Up to 1,600 bar and solenoid injectors on the 2006 Euro 4 engines. No figure for the Euro 5 engines.
Turbocharger	Fixed geometry on the 2006 Euro 4 engines. Peugeot does not state the type for the Euro 5 engines.
Exhaust gas recirculation	Electronically controlled, with a water-cooled heat exchanger (2006 Euro 4 engines)
Particulate filter	On every Euro 5 version
Service interval	48,000 km or two years (2014 range)

Peugeot published no compression ratio. Ford gives 15.5:1 for its own Euro 5 2.2 Duratorq TDCi of 100 and 125 PS in the Transit. In October 2005, the trade site just-auto reported that Ford would build a dedicated 2.2-litre commercial diesel at Dagenham for the Transit and for the new PSA vans.

Peugeot changed the engine for Euro 5 in July 2011, and the code tells you the version:

Code	Version	Emission standard	Power	Torque	Period
4HV	HDi 100	Euro 4	74 kW (101 PS)	250 Nm	2006 to July 2011
4HU	HDi 120	Euro 4	88 kW (120 PS)	320 Nm	2006 to July 2011
4HG	HDi 110	Euro 5	81 kW (110 hp)	250 Nm	From July 2011
4HH	HDi 130	Euro 5	96 kW (130 hp)	320 Nm	From July 2011
4HJ	HDi 150	Euro 5	110 kW (150 hp)	350 Nm	From July 2011

The power and torque figures come from Peugeot, which does not name the codes. The codes 4HV, 4HU and 4HH appear with these outputs in the type-approval data of the Dutch vehicle authority (RDW). The codes 4HG and 4HJ come from parts catalogues. The Dutch data also hold a Euro 4 code 4HM with 96 kW, in base and motorhome-chassis approvals.

Peugeot says that the 130 and 150 hp versions have a specific piston cooling system and engine mapping, compared with the 110 hp version. On the Euro 4 engines, the 120 hp version had its own engine map and a dual-mass flywheel. From July 2015 for the Boxer passenger version and from September 2016 for the vans, Peugeot replaced the 2.2 HDi with the 2.0 BlueHDi for Euro 6, an engine designed and produced by the PSA Group.

Which Code Do You Have?

The Boxer and the Jumper have used several diesel engines, so read the code before you order.

Code or engine	How to recognise it
4HV, 4HU	2.2 HDi Euro 4, from 2006 to July 2011. Same 2,198 cc family as the 4HH.
4HG, 4HH, 4HJ	2.2 HDi Euro 5, from July 2011. Registration and type-approval records can show the shared code 4H03. The power tells the versions apart: 81, 96 or 110 kW.
3.0 HDi	2,998 cc, from the Sofim engine plant. Sold beside the 2.2 HDi from 2006.
2.0 BlueHDi	Euro 6 PSA engine, from 2015 (passenger version) and 2016 (vans).
2.2 BlueHDi, from 2019	2,179 cc. The Dutch records list it as 4HA, 4HB and 4HC. A different engine from the 2,198 cc 2.2 HDi.

Some parts sites and guides, and an earlier version of this page, describe the 2.2 HDi of the Boxer as a DW12. The DW12 is a PSA engine. In the Dutch records, the 2.2 HDi codes of the 2006 to 2016 Boxer and Jumper have 2,198 cc, and the DW12 codes have 2,179 cc.

If your van has the Euro 5 3.0 HDi, see our F1CE3481 engine.

Which Vans Have the 4HH

We supply this engine for the Citroën Jumper and the Peugeot Boxer.

In the type-approval data of the Dutch vehicle authority, the Jumper approvals carry both trade names, Jumper and Relay. L'argus wrote in 2010 that Fiat built both vans at its Sevel Sud plant in Italy. Peugeot changed the whole Boxer range to Euro 5 engines in July 2011, and the 4HG, 4HH and 4HJ stayed in the vans until the 2.0 BlueHDi replaced them.

The Fiat Ducato of the same generation used this engine family only in the 100 hp Euro 4 version (4HV), according to the Dutch data and L'argus. Euro 5 Ducatos have Fiat engines, such as the 2.3 MultiJet (F1AE3481).

The Ford Transit uses the Ford 2.2 Duratorq TDCi of the same family, with Ford engine codes. Both engines have 2,198 cc and the same bore and stroke, and one Euro 5 injector part number carries Peugeot and Ford references. We found no document that says that the two engines are identical. If your van is a Transit, see our DRF engine for front-wheel drive and our DRR engine for rear-wheel drive.

What Peugeot, Citroën and the Authorities Documented

These documents cover the 2.2 HDi, or vans that Peugeot and Citroën sold with it:

UK recall R/2015/057, March 2015: 1,475 Peugeot Boxer III vans built from 5 September to 12 December 2014. An internal component of the injector might not meet its specification, which could reduce the fuel pressure. The engine could then fail to start or stall. Dealers checked the identification numbers of the injectors and replaced them where necessary.
UK recall R/2015/055, March 2015: 1,145 Citroën Relay vans built from 11 September to 13 November 2014, with the same defect and the same remedy.
France, April 2015: L'argus reported the same campaign for about 1,400 Boxer III vans with the 2.2 HDi built from 5 September 2014 to 22 January 2015. It wrote that the Citroën Jumper had the same problem, and so did the Ford Transit and Ranger.
UK recall R/2015/025, February 2015: 13,853 Ford Transit and Ranger vehicles built from September 2014 to January 2015. The internal valve of a batch of injectors could fail, reduce the fuel pressure and stop the engine without a restart.
Euro 4 pistons, reported by L'argus in August 2010: owners of Jumper and Boxer 2.2 HDi 100 and 120 vans reported a loss of power, knocking and running on three cylinders. With the cylinder head off, the piston was seized or cracked, or melted by excess pressure in the cylinder. L'argus named the high-pressure fuel limiter as the cause, with the injector staying open, and wrote that the fault could affect every van built up to the end of July 2008. PSA paid part of the repair cost within 48 months or 150,000 km. This was not a recall, and we found no PSA document on it.

None of these documents shows that every 4HH is defective, or gives a failure rate or an expected life for the engine. Three more limits apply:

The injector recall covers vans from a few months of production. The UK records do not name the engine, and L'argus names the 2.2 HDi.
The piston report concerns the Euro 4 HDi 100 and 120 built up to July 2008, not the 4HH.
In the UK recall data, we found no other recall for the engine, fuel system, turbocharger, EGR, timing drive or cooling of Boxer III and Relay vans built from 2006 to 2016. We could not search the EU Safety Gate or the German and Spanish recall lists.

Check your own van before you assume anything. In the United Kingdom, the DVSA service checks by registration or VIN. In other countries, a Peugeot or Citroën dealer checks the VIN for open campaigns. A recall that names your model covers only the build dates in its notice.

The Problems, One by One

Injectors and the 2015 Recall

If the van was built from September 2014 to January 2015 and does not start or stalls, ask a Peugeot or Citroën dealer to check the recall first. The dealer reads the identification numbers of the injectors and replaces the ones that do not conform.

Outside the recall, a worn or sticking injector causes a rough idle, smoke, knocking, hard starting and a loss of power. Test in this order:

Read the stored fault codes, and compare the actual rail pressure with the target value.
Read the fuel quantity correction of each injector with a scan tool. A value far from the others points to that injector.
Run a back-leak test, which measures how much fuel each injector returns to the tank.
Check the fuel filter for water and dirt before you fit new injectors.

Denco Diesel & Turbo, an Australian diesel injection specialist, lists one Euro 5 2.2 injector (Siemens VDO A2C59517051) with Peugeot, Ford and Mazda references. It states that an authorised workshop must code each new injector to its cylinder with diagnostic equipment.

Knocking, Smoke and Piston Damage

The piston damage that L'argus reported concerns the Euro 4 HDi 100 and 120 built up to July 2008. L'argus adds that on the first engines, the piston rings could be fitted upside down. We found no document that reports the same faults on the Euro 5 4HH. On any version, a knock with smoke and a loss of power can mean internal damage. Test it in this order:

Stop driving if the engine knocks and smokes. More driving increases the damage.
Measure the compression of all four cylinders and compare them.
Measure the crankcase pressure. A damaged piston or piston ring raises it.
Look at the piston crowns with a borescope through the injector or glow plug bores.
Test the injectors. An injector that stays open can damage a piston, so replace it before a new piston or a new engine goes in.

A damaged piston means that the engine comes apart. If the cylinder walls are undamaged and measure within specification, a rebuild with new pistons is possible. Scored cylinder walls, damage on several cylinders or metal in the oil point to a replacement engine.

Crankshaft Pulley

febi, a German parts maker, describes a fault on front-wheel-drive Ford Transit and Tourneo vans with the 2.2 TDCi Duratorq. Water and road dirt get into the vibration damper of the crankshaft pulley and wear it out. The signs are abnormal noise and vibration at the timing end of the engine, the alternator warning lamp, and a damaged power steering belt or one that has come off. febi's fix is a new crankshaft pulley with new bolts, and new auxiliary belts where the old ones are worn or damaged. Autoelectro, a UK maker of alternators and starters, describes the same contamination on Transits with the 2.2 TDCi from 2006 to 2012, with a charging fault or noise from the belt drive.

Neither document names the Boxer or the Jumper. We include the fault because the Transit uses the same Ford 2.2 family. If your van shows these signs, check the crankshaft pulley before you replace the alternator.

Engine Control Unit

ECUSale, a Polish seller and repairer of engine control units, says that the Boxer and Jumper 2.2 HDi use a Continental SID208 engine control unit. It names water or moisture in the housing as one of the most common causes of failure, because the unit sits where water runs off the windscreen scuttle. Its signs are no start, stalling, limp mode, and lost contact between the diagnostic tool and the unit. ECUSale gives no model years and no engine code, and we found no Peugeot or Citroën document on this fault.

Before you replace the unit, check its power supply, its earth connections and its wiring, as ECUSale also advises, and look for water in the connector and the housing. Clear the scuttle drains and repair the leak, or the new unit fails the same way. Ask the supplier of a replacement unit how it will program the unit for your van.

Turbocharger

We found no recall or manufacturer document on turbocharger faults on this engine. A failed turbocharger can be the result of a fault elsewhere, such as a poor oil supply or dirt in the intake. Check the engine oil, the oil feed pipe and the air intake before you fit a new turbocharger.

Timing Chain

The 2.2 HDi drives its camshafts with a chain. For the Euro 5 engines, Peugeot states a timing chain that does not require replacement, so the service schedule has no chain change. We found no recall or specialist document on chain or tensioner failures on this engine. If a rattle comes from the timing end, a workshop checks the chain and the tensioner.

Particulate Filter

Peugeot fitted a particulate filter to every Euro 5 version of the 2.2 HDi. Peugeot does not say whether the filter uses a fuel additive. Repeated short trips leave soot in the filter, and a full filter reduces power and turns on a warning lamp. We found no recall for the filter on these engines. Before it replaces the filter, a workshop reads the soot load and the pressure difference across it, and checks the EGR system and the injectors.

Claims We Could Not Confirm

Other pages about this engine make claims that no document in our source list supports. We list them so that you can weigh what you read elsewhere.

A DW12 engine. The 2.2 HDi of the 2006 to 2016 Boxer and Jumper has 2,198 cc and comes from the Ford and PSA cooperation. The DW12 has 2,179 cc.
The name P22DTE. It appears in parts catalogues. We found no Peugeot, Citroën or Ford document that uses it.
A 150 hp 4HH. The Dutch type-approval data give the 4HH 96 kW (130 hp). The 150 hp version is the 4HJ.
A compression ratio of 17.5:1 for the 4HH. Peugeot published no figure. Ford gives 15.5:1 for its Euro 5 Transit engines of 100 and 125 PS.
An oil pump replacement programme for the Euro 5 2.2 engines. Owner forums mention one. We found no recall and no Ford or PSA document.
Diesel runaway, a fifth injector for the particulate filter, and timing chain stretch as typical 4HH failures. We found no document on this engine for any of them.

We found no published document that confirms these claims for this engine, so base the decision on the measurements from your own van.

Is the 2.2 HDi (4HH) Reliable?

No public data gives a failure rate or an expected life for the 4HH, so we do not quote one. The manufacturer actions that we found cover one batch of injectors on vans built from September 2014 to January 2015. The piston damage that L'argus reported concerns the earlier Euro 4 engines built up to July 2008.

Peugeot changed the engine for Euro 5 in July 2011, and the 110, 130 and 150 hp versions differ in piston cooling and engine mapping. A fault on one version does not prove the same fault on another, so find out which version you have. The build date and the power of the van tell you.

Repair, Rebuild or Replace

Base the decision on the damage the workshop measures. If a recall is open, get the recall work done first.

What the workshop finds	What usually follows
An open injector recall	A Peugeot or Citroën dealer does the recall repair at no cost.
A worn injector, with even compression on all cylinders	Replace the injector and code it to its cylinder.
A worn crankshaft pulley	Fit a new pulley with new bolts, and new auxiliary belts where the old ones are worn or damaged.
Water in the engine control unit	Repair the leak or the blocked drain first. Then repair or replace the unit.
A failed turbocharger	Repair the cause first. Then fit the turbocharger.
A full particulate filter	Find out why the filter does not regenerate before you replace it.
A damaged piston, cylinder walls within specification	Rebuild with new pistons, or compare that quote with a replacement engine.
Scored cylinder walls, damage on several cylinders, or metal in the oil	Fit a replacement engine.

Before you decide, ask the workshop for the measurements behind its advice: the stored fault codes, the compression on each cylinder, the injector correction values and back-leak results, and the borescope images. Then get two written quotes for the same van, one to repair the confirmed fault and one to fit a replacement engine with all parts transferred. Weigh both against the value of the van and the warranty on the work and on the engine. For a rebuild, also ask which original parts the workshop will reuse and whether it measured them.

How to Confirm You Need a 4HH

Read the engine code on the engine. We found no Peugeot or Citroën document that shows where the code sits on the Boxer and the Jumper, so send the supplier a clear photo of the code and of the plate.
Check the registration or type-approval data. They can show 4H03 instead of 4HG, 4HH or 4HJ. The power tells you the version: 81 kW for the 4HG, 96 kW for the 4HH and 110 kW for the 4HJ.
Check the build date. Vans built before July 2011 usually have the Euro 4 engines 4HV or 4HU.
Do not confuse the 2.2 HDi with the 2.2 BlueHDi from 2019. That engine has 2,179 cc and the codes 4HA, 4HB or 4HC.
Before you order, compare the scope of supply: which parts come with the replacement engine and which you move over from the old one. Give the supplier the VIN, the engine code, the power and the year.

If the Engine Must Be Replaced

If the measurements point to a new engine, Majestic Engines supplies a factory-new 4HH engine for the Boxer and the Jumper. The product page lists the engine codes it covers, the vehicles it fits, what it includes, the price and the delivery time. Our warranty policy explains the 12-month commercial warranty and its conditions. If you are unsure which version your van needs, contact us with the engine code, the power and the VIN before you order.
