Seat Arosa Diesel engine trouble

Right, I'm at my wit's end with my 2001 Seat Arosa diesel. It's throwing a fit. The engine light is on, and it's jerking like crazy when I accelerate. Plus, there's this awful whistling and loud hissing sound when the turbo kicks in. Sometimes it even stalls at idle. Fuel consumption has gone up, and power is way down. I suspect the boost sensor, especially since it feels like the turbo system is going haywire and there seems to be an issue with the air intake. I've had a quick look, and my gut feeling is telling me it's a dodgy cable or plug connection to the sensor. Anyone else experienced this?

Sounds familiar. I had a similar issue with my Arosa. Check the boost sensor and its connection. Could be the culprit.

Thanks for the quick reply. Where exactly is the boost sensor located, and what should I be looking for in terms of a bad connection? Is it visibly obvious, or will I need a multimeter?

It's usually the connection. For me the sensor was visibly ok, but the car was exhibiting all the same symptoms. I'd advise taking it to a workshop to check it out properly. Better safe than sorry.

Thanks a lot for your help. I took it to a local shop, and you were spot on. Turns out the boost pressure sensor cable had a bad connection. They cleaned it up, and all is well. 95€ later and she's running like new.
