ABS/Hill Start warning light

We were in France last week and the ABS/Hill Start yellow warning light showed on the dashboard and the cruise control turned itself off. Shortly afterwards the handbrake yellow light came on. The van was still drivable and the handbrake did work when parked. We had to stop our camping tour and wait over the weekend for a Mercedes Garage to open. The ABS light had gone off by then (we did slight steering L to R while driving along as per handbook). The garage were good in that they ran it through the diagnostics, played about with the handbrake switch and the light when off - hurrah! Didn't charge us for it. Continued on our journey and an hour later both lights came back on - boo! We can only think it was: hot weather which affected the electronics, or recent complete tyre change before we left which affected the sensor, or speed bumps in every little village we went through, or all three. Plus parking brake was inadvertently turned on while pulling off from parking space due to driver error. Now safely back in the UK, the warning lights have gone (for the time being). I think it's got to be more than the van being home sick. Has anyone else had the same problem and did they get to the bottom of it? Thanks for any comments.

Hmm well the one time I had those symptoms was in a old 1999 Vito when one of the sensor cages came off the drive shaft. The systems don’t seem to have changed much if the abs is playing up lots of stuff just doesn’t work. It could be a temperamental sensor or poor connection, I really don’t know how the later model R/Awd Vito’s do all that these days but it seems like you need to get things checked over but don’t accept any maybe’s from the engineers unless they are expecting a maybe payment.

Thanks, I think you're right, it's got to be something to do with the sensors, especially since we had all the tyres changed before we went. Will keep you posted.
