The yellow tyre light came on on Sunday so I checked my tyre pressures and all were okay. I therefore tried to save pressures via the DIS, and although it seemed to be storing the pressures the yellow deflated tyre symbol remained on.

Last night I tried to investigate with VCDS - there was a fault - intermittent rear antenna so I cleared this - still no joy. Looking at each monitor I only seem to be able to access the last stored pressures (which are all over the place - 3.2 - 2.95 bar) nothing about current pressure, battery life etc.

I unplugged and re-plugged the antenna, test drove, checked again with VCDS and still no other info returned from the sensors. I have disabled the system for now via VCDS to get rid of the warning.

Can anyone help with suggestions as to the next stage - I guess the antenna if none of the sensors are sending anything useful ?

I had the same issue, just put it down to a faulty sensor and switched it off via the VCDS. Either that or get new TPMS's.

Get them switched off, pain in the arse if you ask me

Exactly this, I hate them

I think you will find they are now an MOT requirement, rear antenna is cheap and easy to change.

Really ????? How would they know ?

Only on cars registered after 1 Jan 2012 so no probs with the B7...

Have ordered an antenna as seems most likely/easiest to test and can't see all 4 sensors simultaneously failing.

Waste of money on a pointless feature tbh, best of luck

Well the antenna arrived and this afternoon I got round to installing it. It is a simple job - simply pull the grille out of the middle of the rear bumper and there it is. A litte metal clip goes flying - from what I could work out it belongs on the middle tab at the bottom - I put it back there but is probably not needed.

Recoded VCDS to enable the TPMS and...yellow error. So tried to store pressures and still yellow error... Wondered if the sensors needed "waking up" hadn't driven the car for a couple of hours and so took it up the road and tried a wheel change instead of store pressures and the error cleared. Stopped & started and all good.

So for those who have a similar problem and want to fix it it is worth trying (or better still borrowing) and antenna.

I took the olds one apart and the contacts had burnt out and was a couple of drops of water inside so 10 years behind the back bumper had taken its toll.
