Primastar ABS Fault

Whoa, that sounds like a proper pain! Lateral acceleration sensor, eh? With those symptoms – ABS light and system failure – it's almost definitely something electronic messing with your traction control and electronic stability program. Have you had any work done recently that might have involved the steering angle sensor or anything around the front suspension? A dodgy connection there could throw things off. A diagnostic scan should pinpoint it, but sometimes the readings can be misleading. I'd double-check all the wiring looms and connections before going any further.

Thanks for the suggestions. I haven't had any work done on the steering angle sensor or front suspension. Can you explain the potential for misleading readings from the diagnostic scan? What parameters should I focus on? Also, what are some common failure points or signs of damage to look for when inspecting the wiring?

Right, misleading readings... sometimes the code points to the sensor, but it's actually the control unit itself that's gone haywire. It's like blaming the messenger! As for the wiring, look for anything obvious – corrosion, chafing, loose connections. Honestly, though, with it being the lateral acceleration sensor and affecting the ABS so directly, it's leaning towards a deeper issue with the control unit. I reckon you need to get it hooked up to a proper diagnostic machine at a workshop, they'll be able to properly interrogate the ABS system and pinpoint the exact cause. Sadly, it sounds like it might be expensive.

Thanks for the help. I consulted a workshop, and they also suspect a defective control unit. The estimated repair cost is about 1000€. I'm confident that fixing it quickly will keep the vehicle safe and reliable. Thanks again.
