Mini Paceman Diesel Tank Ventilation Issue

I have a Mini Paceman as well, and I experienced very similar symptoms not long ago. The engine light kept coming on, and the engine would occasionally stall, especially at idle. Have you checked the tank ventilation system? In my case, the purge valve was the culprit. I would suggest getting that checked.

Could you perhaps elaborate on which specific components of the tank ventilation system were affected in your case? I am curious if the issue was solely confined to the purge valve or if the pressure sensor was also implicated. Furthermore, were there any discernible signs of hose degradation or blockage that you observed during your inspection?

Certainly. While I did perform some preliminary checks myself, I must confess that I ultimately sought the expertise of a qualified technician. As I recall, the primary issue stemmed from a malfunctioning purge valve, although the pressure sensor was also exhibiting erratic behavior. Whether the hoses were definitively clogged, I cannot say with certainty. Given the potential complexity of the system, and considering the possibility of unforeseen complications, I would strongly recommend entrusting the automotive repair to a professional.

I appreciate you confirming my suspicions. I had the vehicle inspected at a reputable workshop. The tank ventilation valve was indeed faulty, likely due to clogged hoses, as I initially suspected. The repair, including a new purge valve and associated pressure sensor adjustments, amounted to 175€. The engine light is now off, and the engine no longer stalls. Thank you for your assistance.
