AdBlue system failure (start countdown)Exhaust and emissions (AdBlue)

Engine / equipment: 1.5 / 1.6 / 2.0 BlueHDi with AdBlue (Peugeot, Citroën, DS, Opel)
Period mentioned: Approx. 2014 onwards
Symptoms: Emission system fault message and a “starting impossible in X km” countdown, AdBlue/UREA warning and engine light.
Possible cause described: Failure of the AdBlue tank pump module (circuit board, pressure sensor or heater) or of the AdBlue injector. The engine does not stop while driving, but once the countdown reaches zero it will not restart.
Check for the garage: Diagnose with Diagbox or equivalent: AdBlue pressure, flow test and tank temperature.
Cost cited in the source: Complete module or tank: approx. €600–1,500 (estimate)A rough figure from the original database, not an up-to-date quote.

1.5 BlueHDi camshaft chainValve timing

Engine / equipment: 1.5 BlueHDi (DV5): Peugeot 208/2008/308/3008/5008/508/Rifter, Citroën C3/C4/C5 Aircross/Berlingo, Opel, DS, Fiat
Period mentioned: 2017–2023
Symptoms: Rattle from the top of the engine, loss of power; in severe cases the chain breaks and the engine fails.
Possible cause described: The 7 mm chain linking the two camshafts wears prematurely, influenced by soot in the oil. Stellantis replaced it with an 8 mm chain in 2023 and opened an inspection campaign.
Check for the garage: Ask the dealer whether the car is in the campaign (free inspection and replacement if needed) and whether the 8 mm chain is fitted.
Cost cited in the source: €700–1,400 for the chain; €4,000–7,000 if it breaksA rough figure from the original database, not an up-to-date quote.

Applies if: Only cars built from 7 to 10 April 2021 (1,279 cars in France). Confirm by VIN.

The engine runs but the car does not move: broken right driveshaft on the April 2021 C3Transmission

Engine / equipment: Facelifted third-generation Citroën C3 (all versions)
Period mentioned: 2021
Symptoms: The right driveshaft can break suddenly: the engine keeps running but the wheels no longer get drive and the car does not move.
Possible cause described: Insufficient heat treatment on one of the driveshaft gears. Citroën recalled 1,279 C3 in France built from 7 to 10 April 2021 (and two C-Elysée): it checks the transmission and replaces the right driveshaft if needed.
Check for the garage: If the engine revs and the car does not move, do not carry on: call for a tow. Check by VIN with Citroën whether the car is in the recall; outside those dates, the garage checks the driveshafts and gearbox.
Cost cited in the source: Free under the recall.A rough figure from the original database, not an up-to-date quote.
