Drove home from work last night and car was fine. Around an hour later went back out and traction control light came on straight away and stayed on. Whats the most common thing to look for as I'm gonna get it in garage tonight for a look.

MAF, get it on a fault reader.

I changed my maf last night. I put a carbornio on Sunday gone and changed my maf to a spare i had but car ran rough so changed it back last night to the original. Runs spot on again but the dam traction control light. Will put it on scanner tonight just was after info for different things ti look for.

you will need to get the code as it might be one that needs to be cleared to turn off

Will give it a go when i finish work. Failing that boxes of matches. I'd save a fortune, as i need some stronger engine mounts.

Could be the brake light switch going or gone? This is what happened on mine.
