Seat Ateca Diesel Engine Troubles

I am pulling my hair out here. My 2018 Seat Ateca with a diesel engine is giving me headaches. It has done 173151 km. The check engine light is on, and I've noticed a significant loss of power, especially when accelerating. The engine response is terrible, and I'm burning through fuel like crazy. I suspect it might be the crank sensor causing issues with the crankshaft to camshaft reference value. Anyone had similar issues?

Whoa, that sounds rough. I had something similar happen with my old Renault Megane, although the symptoms weren't exactly the same. Check engine light was on, and the car felt sluggish. They mentioned something about the timing being off. Did you try scanning for error codes? That's how I found out what was wrong with my Renault.

Yeah, I scanned it, and it throws a code related to the crankshaft to camshaft reference value. So, I am suspecting the crank sensor. When they mentioned the timing being off on your Megane, was it also related to those sensors?

Ah, crankshaft to camshaft reference value, yeah, that rings a bell. In my case, the faulty sensor was messing up the engine synchronization. I'm no expert, but it sounds like you're on the right track with the crank sensor. If the code points to it, and you're experiencing those symptoms, it's very likely the culprit. I'd say get it checked by a professional to be sure. It's a pain, but better to be safe than sorry.

Just letting you know it's sorted. It was indeed the crank sensor as suspected. Cost me 340€ at the workshop, but now my Ateca runs like a dream again. Thanks a lot for your help. Really appreciate it.
