If the fault described above occurs together with the listed error codes, a possible cause is a faulty EGR valve (exhaust gas recirculation valve).
Remedy:
In order to exclude other sources of the problem, first check the periphery (power supply, plug connections, etc.) of the exhaust gas recirculation system.
If no fault is determined here, check the article number of the EGR valve.
The items with the following article numbers are faulty
- A651 140 06 60
- A651 140 07 60
These parts must be replaced with an updated EGR valve with the article number A651 140 08 60.
After the EGR valve has been replaced, read the error memory of the vehicle using a diagnostic unit and delete existing error codes.
A test drive should then be carried out and the error memory read again.
