Heavy steering and vibration issue

Whoa, sounds like a handful! I had something similar happen with my SL. Not fun at all. The heavy steering and vibrations are definitely concerning. Did you notice if it's worse at certain speeds or during specific maneuvers? In my case, it turned out to be alignment problems after I replaced some suspension parts. Could be related to your automotive sensors issue, but I'd double-check the basics first. Before diving into sensor replacement, have you checked your power steering fluid level? Just a thought!

Thanks for the quick reply! The power steering fluid level is good, I checked that first thing. The heavy steering and vibrations seem to be more noticeable at lower speeds, especially when parking or making tight turns. So, when you say alignment problems after replacing suspension parts, are you suggesting the steering sensor was damaged during the suspension work, or was the alignment just off afterward, causing similar symptoms? Was your steering angle sensor defective?

Okay, low-speed issues point even more towards that steering sensor. No, the suspension work didn't damage the sensor, it was just a coincidence that the alignment was off afterward. But the symptoms were similar enough to throw me off for a bit. It's definitely worth getting the sensor checked out properly. I'd recommend taking it to a workshop that specializes in Mercedes. They'll be able to diagnose the problem accurately and tell you if it's just a simple sensor failure or something more complex. That way, you can avoid unnecessary sensor replacement and potential alignment problems down the road.

Appreciate the advice! Took it to a local shop. They confirmed the steering angle sensor was defective and the coding was faulty. Sensor replacement and recalibration sorted everything out. Cost me 195€ all in. Thanks for pointing me in the right direction!
