2 known faults with sources

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.

Applies if: Only if fitted with the automatic gearbox described in the record.

AL4 / DP0 automatic gearbox pressure regulationAutomatic gearbox

Engine / equipment: PSA/Renault AL4 (DP0) four-speed automatic in Peugeot 206, 207, 307, 308, 406 and 407, Citroën C3, C4, C5, Xsara and Xsara Picasso, and DS3
Period mentioned: Approx. 2000–2015
Symptoms: The “Sport” and “Snow” lights flash together or “Gearbox fault” appears; very harsh shifts before the gearbox goes into limp mode in 3rd (only 3rd and reverse). It often happens when cold or after a few minutes' driving and clears after restarting the engine.
Possible cause described: The control unit sees a difference between calculated and actual pressure. The most cited cause is the pressure regulation solenoid (EPDE), though internal leaks or the pressure sensor are also possible. With badly degraded fluid, the fluid wear counter also triggers limp mode. Some owners replace the solenoid without fixing it.
Check for the garage: Read the codes with PSA-compatible equipment (Diagbox/Lexia) and log line pressure while driving, especially when cold. Check fluid level and condition and, if changed, use the specified fluid and reset the wear counter. Also check the lever position switch.
Cost cited in the source: No verifiable estimate in the sources; the solenoid is a replacement part and, according to a forum, it can be changed without removing the gearbox.A rough figure from the original database, not an up-to-date quote.
