Bit of background. 2007 Fabia 1.9TDi PD. About 138,000 miles. Had all 4 ABS sensors changed due to fault with one of them. ABS working correctly. before we did this work we had an intermittent ESP warning light - would come on after about 10-15 minutes driving. Can anyone suggest where we start looking now. Steering angle sensor, ABS control, etc.

Thank you

Paul

Start here:

In your case it may be that your battery light still works, as I suspect it's a broken DFM wire that's giving your warning light after 10 mins, rather than the exciter (blue) wire.  Both may well be busted though, so do this test and see.
