ABS light on soon after full service/new tyres

[pyjamadrama]

Hi y'all

I had my Cupra Sport serviced inc a full set of new tyres. When I got home I realised that the fuel was way down beyond normal; it turned out the garage had given me back the car with all four tyres almost half deflated.
I sorted that easily enough but within a few weeks the ABS light came on. The brakes however work perfectly. Is it likely that the tyre change affected the sensor/s? If so, before it goes for next MOT is there anything I can do to fix that eg. clean sensor? If not, what work am I likely looking at and at what sort of cost?
While Im here, is it right that the rear number plate bulb is NOT a Test fail?? Whitecraigs Garage formerly of Afton/Tantallon St. failed my previous car, a Punto on only that..

PS. Has anyone got the name of a good keycutter for car keys?
Ta.

Reg bulb is a fail, no 2 two ways about it
bit of a shite garage to fit new tyres and not inflate them correctly
ABS light is probably just unlucky to be honest mate, you could try and clean each sensor with a small paint brush incase the sensor or the pick up is soiled!

ABS failure won't affect the normal operation of the brakes.

Is it likely that the tyre change affected the sensor/s?

Unlikely, in my opinion.

If so, before it goes for next MOT is there anything I can do to fix that eg. clean sensor?

You may have a dirty sensor, it may be worth cleaning the tips with brake cleaner.

If not, what work am I likely looking at and at what sort of cost?

Usually a sensor has failed. You need to hook it up to vagcom or a fault reader to find out which one. A sensor costs ~£20 from a motor factor. Plus labour, if you don't want to fit it yourself. It's not a difficult job.
