What to watch for
The list covers the generation, the engines and the transmissions. Once you pick the version, only the faults that apply to it stay.
Plastic guide rails hold the timing chain in place.
Applies to the engine B48B20, B38B15.
Repair: 700–2,900 EUR
The multi-part crank hub is held in place only by the clamping force of the crankshaft bolt and the friction between the mating surfaces.
Applies to the engine S55B30.
The high pressure pump of these common rail diesels (Bosch CP4) can fail while driving.
Applies to the engine N47D20, N57D30, B47D20.
In these engines the water pump is not belt driven but has its own electric motor.
Applies to the engine N55B30, B38B15, B48B20 and 1 more.
The chain guide of the early N20 engines is brittle: if it breaks, the chain goes slack, and from then on the timing is imprecise.
Applies to the engine N20B20.
The internal fins of the exhaust gas recirculation cooler crack over time, and glycol coolant leaks into the intake, where it mixes with soot.
Applies to the engine N47D20, N57D30, B47D20.
On the early model years the timing chain of the B47 stretches faster than intended.
Applies to the engine B47D20.
Repair: 1,200–4,500 EUR
The B47 replaced the N47, and the maker fixed the timing chain problem.
Applies to the engine B47D20.
13 more faults belong to this generation. On the version page, only the ones that apply stay.
The manufacturer fixes these for free at a franchised dealer. Ask with the VIN whether it was done. The list covers the whole generation. We did not filter it by model year. Some apply only to a narrower production window.
Most recent: 7 July 2026
SR/02180/26Safety recallFire7 July 2026 · EU Safety GateThe RSW22 starter with reinforced water tightness (RWT) may experience increased abrasion of the magnetic contact, causing deposits to build up at the lowest point inside the relay. These deposits may increase relay contact resistance, leading to starting failures or short circuits. If a short circuit occurs, either when attempting to start the vehicle or while driving due to vibration-related movement of the deposits, it could cause a thermal event and increase the risk of fire. The product does not comply with the Regulation on the approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles.
Remedy: Type of economic operator taking notified measure(s): Manufacturer Category of measure(s): Recall of the product from end users Date of entry into force: 07/07/2026
SR/00551/26Safety recallFire30 January 2026 · EU Safety GateThe failure concerns the RSW22 starter, type RWT (reinforced for watertightness). Increased abrasion of the magnetic contact can lead to the formation of deposits at the lowest point of the relay interior. This in turn can increase the resistance of the relay contact, causing accidental ignition or even short circuits, possibly leading to a thermal reaction and fire. The product does not comply with the Regulation on the approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles.

A12/01223/24Safety recallInjuriesno date · EU Safety GateThe accumulator in the driver/passenger head airbag inflator can leak, preventing the airbag to fully deploy if activated in an accident, impairing the protective effect of the airbag. Moreover, the accumulator can detach, entering the interior of the vehicle or becoming detached from the vehicle. This can lead to an increased risk of injury for passengers and/or other road users. The product does not comply with the Regulation on the approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles.

A12/1147/17Safety recallInjuriesno date · EU Safety GateThe bolt on the outside of the seat mechanism of both front seats may not have been properly secured. If the bolt comes loose, the seat can move backwards in the event of a rear-end collision accident, which would increase the risk of injury to the occupants.
Remedy: Type of economic operator taking notified measure(s): Manufacturer Category of measure(s): Recall of the product from end users Date of entry into force: Unknown
SR/00372/26Safety recallInjuriesno date · EU Safety GateThe accumulator in the head airbag inflator may not have been manufactured in accordance with specifications. Over time this could cause it to leak. If activated in an accident, the airbag would not fully deploy, as a result of which its restraining effect would be impaired. In addition, irrespective of the airbag being activated in an accident, the accumulator may detach. In this case, the accumulator could enter the interior of the vehicle or become detached from the vehicle. This could lead to an increased risk of injury for passengers and/or passers-by. The product does not comply with the Regulation on the approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles.

SR/03830/25Safety recallFireno date · EU Safety GateWater may come into contact with the starter relay and gradually cause corrosion. This could affect the electrical connection inside the relay and make the engine difficult to start. It may also result in a short circuit and could cause the starter to overheat leading to a fire when the vehicle is in motion or when it is parked with the ignition off. The product does not comply with the Regulation on the approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles.
