Corsa Injector Drift Compensation

Greetings. While I haven't encountered this specific issue on a Vauxhall Corsa, I did experience similar symptoms with my previous BMW 3 Series. Rough running, check engine light, and associated error codes were present. In my case, it was related to the fuel injection system. Have you used an onboard diagnostics (OBD) scanner to pull the exact error code? Knowing the specific code will greatly assist in pinpointing the root cause, as 'drift compensation' could stem from various issues within the fuel delivery.

Yeah, I scanned it with a generic OBD reader. It spat out a few codes, but the main one was related to the drift compensation, pointing towards injector problems. Was your BMW also flagging injector issues? Did you try anything yourself before throwing in the towel and heading to the garage? Or are we talking a 'get it to the professionals' kinda job?

Indeed, the BMW displayed error codes directly implicating the fuel injectors. Given that your OBD scan is also suggesting injector-related problems, I would recommend consulting a qualified workshop without delay. While certain diagnostic steps can be performed independently, issues within the fuel injection system often require specialized tools and expertise for proper diagnosis and repair. Continuing to operate the vehicle in its current state may lead to further complications. I ended up paying around 820€ to fix it, which was not a bargain.

Cheers for the advice. Bit the bullet and took it to the garage. Turns out, you were spot on, injector valve defective. Bill came to 515€, but at least it's running smoothly again. Lesson learned: sometimes you just gotta swallow your pride and get the pros in!
