Check engine light on

Hi everyone, I'm a bit worried about my Audi A1, built in 2010, with a petrol engine and a good 150k on the clock. The car no longer pulls properly, jerks when accelerating and drinks fuel like crazy. In addition, the yellow warning light from the engine block has come on. Somehow this sounds to me like a problem with the intake manifold pressure sensor. Have any of you had similar experiences and can give me a tip on how to address this with the mechanic? I didn't have a very good experience last time... Thanks in advance for your help!

Hi, something similar happened to me with my 2013 Audi A3. The engine also jerked when I accelerated and the warning light came on. In my garage, it was determined that the intake manifold pressure sensor was defective. So assume that your feeling is correct. It's a serious problem as a faulty sensor prevents accurate control of the fuel/air mixture, which can lead to the symptoms you describe. It has helped me to tell the mechanic directly that I suspect the intake manifold pressure sensor could be faulty. Then at least he knows that you have already done some research into the matter. Good luck!

Hey, thanks for your reply. It's really stupid that you had the same problem. Can you still remember how much you paid for the repair? And have you had any other problems since then or has everything been fine again?

Hi again, yes, that was really stupid, but since the visit to the mechanic, the problem with the malfunctioning intake manifold pressure sensor has been resolved. I had to fork out €235 to fix a major vacuum leak. Since then everything has been running like clockwork again, no more setbacks. Hope it goes just as smoothly for you!

Many thanks for the information. 235 is not exactly cheap, but the main thing is that the car runs smoothly again afterwards. I will follow your advice and point out the intake manifold pressure sensor directly to the mechanic. Hopefully I won't have any more problems afterwards. Thanks again for your help. I'll let you know how it goes.
