Hi Hanna
Not sure if this helps but many years ago I used to drive Volvo cars. When I had a bulb blow it was changed with a standard type bulb and it worked just fine, but... A warning light for a bulb failure came on on the dash and the reason was that Volvo fitted special bulbs (can't remember what was "special" about them now) and as soon as I fitted a Volvo bulb all was well again.
Is it possible that this is a similar problem? Seems a coincidence that the ABS light came on when the bulb was changed???
Maybe worth checking with Hymer to see, try

I had it on a nissan car I owned once.....hade to scrap it......the answer is........................for the MOT TAKE THE BULB OUT...it WILL fail if the light is on.

Could be a wrong bulb, a sensor or other ABS mechanism problem.....all of which were too expensive to do on my nissan.

My guess is the changing of the brakelight bulb is a red herring.

However, Keith is totally correct. A lot of companies now use specialist bulbs which if replaced with standard ones can cause problems. It is all to do with resistances of the coil. I do feel that this has nothing to do with the ABS light and just an awkward coincedence. Obviously I cannot guarantee this.

What next then?

Simply check each ABS sensor in turn, they are relatively simple to replace and if you do it yourself very low cost.

The other suggestion given by who knows! Take the ABS bulb out for the MOT then deal with the problem. But mind you do, ABS is a fantastic feature and one we should not be without if we have it.

Has there been an attempt to clear this error from the ECU ?

Just changing a sensor will sometimes not automatically reset the ABS system.
