Seat Ateca Diesel Engine Power Loss

I'm experiencing some issues with my 2017 Seat Ateca (diesel engine). I've noticed reduced engine power, a warning light, and the vehicle starts poorly. The lights are also weak and flickering. Error memory indicates a faulty generator. I suspect the generator is defective. Anyone else had this?

A 2017 Seat Ateca with a diesel engine is experiencing reduced power, a warning light, poor starting, and flickering lights. The error memory suggests a faulty generator, which is suspected to be the cause of the issues. It is recommended to check battery connections and measure voltage to confirm a charging system failure. The workshop confirmed the generator is defective, and replacement is needed.

Sounds familiar. I had similar issues with my Ateca. Check your battery connections and measure the voltage when the engine is running. A voltage drop is a strong indicator for the charging system failure. The starter motor might also be affected. Is the battery low?

Thanks for the quick reply. Where exactly did you measure the voltage? And do you remember if you also had an engine misfire?

I measured the voltage directly at the battery terminals. And yes, I did have an engine misfire occasionally, especially when the battery was really low due to the faulty charging system. Eventually my car stalled. I'd get it checked at a workshop to be sure, but it sounds like a defective generator. Good luck.

The workshop confirmed the generator is the problem. Replacement will be 960€. Thanks for the help.
