Problems with diesel Golf 2009: Black smoke, indicator light, engine stuttering and possible defective rail pressure sensor.

Hi, repair professionals! I'm currently having a few problems with my 2009 diesel Golf. My car is causing a lot of trouble: it smokes black when accelerating, the indicator light is constantly on and sometimes the engine simply cuts out. In addition, there's a loss of power, the engine doesn't run smoothly, the car jerks when accelerating, fuel consumption has increased and the exhaust smells really bad. It also stalls from time to time when idling. I suspected that a defective signal from the rail pressure sensor could be the reason. What do you think? Does anyone have any experience with this and any tips on what I could do? How did it turn out in the workshop and what did you pay for it? I would appreciate your advice.

Hi, I had a similar situation with my 2007 diesel Passat. In terms of cars, I would say I have a bit of experience. In my case it was a wiring harness/plug that was faulty and I had to go to the garage. The repair cost me 95 euros. It could be that this is your problem - a faulty wiring harness/connector. Can you give more details about your vehicle? Maybe I can help you with more information.

Hey, thanks for your quick reply! My Golf has now run 221489 km, quite a lot, right? I had the last service about 6000 km ago, when everything was checked and no problems were found. I'm really at a loss. A faulty wiring harness would of course also be possible, I'll check that! Do you have any other guesses as to what it could be?

Hey, no problem, you're welcome! Your Golf has already done a fair amount of mileage, but that's not necessarily the problem. Sometimes parts can simply give up the ghost. So, if the wiring harness is OK, it could possibly be the EGR valve. This can also fail at high mileage and would correspond to your symptoms. Perhaps the air mass is not set correctly, which could also lead to the problems. A faulty signal from the rail pressure sensor could of course also be a possibility. It would be best if you had a fault readout carried out. But these are just some of my thoughts. Take a look at these things, that should help. Keep me posted, I'd be interested to know what it was in the end!

Thank you for the other tips, I will definitely take them into consideration! I'll go to the garage tomorrow and have a fault readout done. Let's see if it's the EGR valve or something else. I'll stay in touch about your news! You'll definitely hear from me as soon as I have any news. See you then and thanks again for your help!

Hi Recas, the ABS/ESP warning lights could indicate a problem with the ABS or ESP system, which are crucial for your car's safety. It could be due to a faulty wheel speed sensor, a problem with the ABS pump or module, or even low brake fluid level. I would recommend getting your car to a mechanic as soon as possible to diagnose and fix the issue. Please keep us updated on the progress. Do you have any other questions?
