Intermittent traction control light on start up

Featured Replies

Hi Roomster owners,

I’ve had the car 5 years and love it, does local and motorway miles.

I have a strange intermittent traction control light coming on on the second start up (not when first ignition). Auto electrician has looked at it, been back to garage several times but can’t find the fault. Changed crank shaft sensor but didn’t cure it,

Mot is soon and I can’t afford to scrap the car, only has 71196 on the clock, 1.6 diesel.

Anyone any clues? Only code is U101FOO?

Perplexed.

Thanks in anticipation.

When did you last have a new 12v battery fitted ? Can't do any harm trying if it was a few years ago.

Hi thanks for the reply. I asked auto electrician to check the battery and it was ok but will pass your comment on thank you.

Could it be the battery in the key fob playing up?

Cheers

No, just the 12v. It might have zero to do with your issue, but lots of Volkswagen Group cars (Audi, SEAT,Skoda, VW) have odd warning lights with apparently sound, but ageing batteries.

Even my old Subaru started acting odd plus a check engine light, and I trickle charged the battery every couple of months. In the end, the battery still started the car but "fell off a cliff".

Let us know what solves it !

Will do thanks, car runs fine but definitely worth a check as battery is quite old.

Cheers Jules

Hi Prezafab,

Just to let you know I think this has worked with the battery so thank you for suggesting 🙌

Got an MOT today (advisories suggest other stuff now 🙈) but hey ho.

Thank you
