Hey, no problem, I'm glad I could help! So, the repair cost me €345. It was the inner mechanics of the throttle valve that they replaced. And since the visit to the mechanic, everything has been running like clockwork. The fault with the throttle potentiometer had been rectified and there was no trace of the previous problems. The car runs like a new car again! So, don't worry, it seems that going to the garage is the right thing to do in your case.

Hey, that's good to hear! Your information really helps me. 345 is not exactly cheap, but if everything runs like clockwork again, it seems to be worth it. I'll follow your advice and have the throttle body replaced next time I visit the mechanic. Thanks again for your advice and your time! I hope my car runs like a new car again soon! Take good care of yourself and stay in the fast lane, but always within the speed limit! Bye bye!

Hey, I had similar problems with my 2016 Mercedes GLE class diesel. It was a problem with the internal mechanics of the throttle valve. The same symptoms as yours: the engine ran unstable, stalled sporadically and the fuel consumption was also higher than usual. Not to mention the jerking when accelerating. During a thorough inspection, my mechanic discovered that the throttle valve was defective. A new throttle valve was installed, which solved the problem once and for all. Of course, every situation is different, but based on my experience, I would say that your issues could very likely be related to the throttle body. It's definitely something you should address on your next visit to the garage. Hope this helps you!
