Re: ESP and Serv coming on only on moterways or duel carageways after driving in a st
Hmm, you know......I had this EXACT issue on our 320d (hard to compare, i know).....but wait till you get this....
The error that came up was similar but from a BMW perspective, once plugged into a proper BMW DIS diagnostic machine, highlighted that the car would need a new ABS/DSC pump. A rather unhealthy £1300 from BMW. And that is exactly what they wanted to do.
Unhappy with this, I remembered that the car did have a bang on a lower suspension arm while i was replacing the turbo (yes, the past few months have been expensive)
I noticed that on the motorway, the steering was out by about 2 degrees on the steering wheel.
Soooooo, I bought a cheap lower arm on eBay and replaced it, took it for a drive and while teh car obviously still needs a bit of alignment done, the steering was on the money in a straight line.
After about 10 miles.....ba-da-bing......the error lights all went.
The upshot of it is that the steering angle sensor in the steering column was obviously thinking that car SHOULD be turning but the ABS sensors in the wheels all dictated the car was going straight and as such, it threw an error.
So, the DSC in teh CLio will work in a similar way I would imagine.
Did you have the alignment done lately, have teh steering wheel off or hit a big pothole that could have caused alignment issues?
