Driving home yesterday and about 5 miles out after a round trip of some 50 miles the dash suddenly lit up like a Christmas Tree!  All very festive but also somewhat concerning!

The following warning lights came on:

1.    Tyre Pressure

2.    Traction Control/Electronic Stability Control

3.    ABS

4.    Power Steering/Steering Lock

5.    Lamp Failure

However, the car still appeared to drive normally and got us home without further incident.  It was raining at the time so wipers and headlights were on.

This morning, having plucked up courage to investigate I started up the car and found that only the first 3 warning lights listed above came on. However, after driving no more than 200 yards around my drive, all the remaining warning lights extinguished! I have not yet ventured out on to the road with the car to see if they stay off!

By way of further background the tyre pressure warning light came on during a trip a few days ago but extinguished itself again after 10 minutes or so.  All tyre pressures were OK and more or less the same.

Late last year this car suffered from a leaking sunroof which saturated the passenger and nearside rear footwell. The sunroof seal was fixed under warranty (the car was a Skoda approved vehicle). The thought occurs that this issue might have been caused by water ingress corroding any floor mounted electronics or wiring and that it is also likely to recur. Can anyone offer any insight to the problem?  I hope I’m not going to regret not rejecting the car when I had the sunroof issue!

exterior temp sensor failure

My guess would be the battery is failing.  Measure the resting voltage one morning after leaving the car standing overnight.  Do this before you switch on the ignition or start the car.  The resting voltage should be an absolute minimum of 12.4V and ideally nearer 12.7V.

Did you do a reset on them after that?

Thanks for the replies so far. I will check the battery voltage tomorrow if it stops raining!  It is still the original battery as far as I know so is unlikely to be in prime condition but to give rise to these, hopefully, false alarms while the enigine is running seems a little odd.

I did not reset the tyre pressure monitoring although I now see that the manual recommends that you do so.  Another job for when it stops raining.  Hopefully not the exterior temperature sensor as removing the front grill looks a pain especially if it doesn't stop raining!

Had same earlier this year. On diagnostic plug-in, root cause was failed NSR ABS sensor. Caused cascade of other lights. Until replaced, sometimes 3 lights, sometimes 6, sometimes no lights. Advised that not unknown across certain VAG models. Since replacement (under extended warranty), no issues.

As above, most likely an ABS sensor but will require VCDS scan to confirm.

Well dry this morning so checked battery voltage after the car had been standing overnight, 12.26V so not ideal.  Ajusted all tyre pressures and reset tyre pressure monitor.  The exterior temperature monitor is still working so I image that can be ruled out.  However, it was dangling free having fallen out of its mounting bracket, if it was ever in there as that section of the wiring loom looks too short.  Not a simple task to re-locate it without removing the grill unless you have 8 inch long fingers although I gather some have succeeded.  I expect I will resort to just attaching it to the grill with a cable tie.

My guess is that it will prove to be an ABS sensor but unfortunately I do not currently own a VCDS scanner and it is likely to be a little while before I have a reason to use the car again to see if the problem recurrs.

 

 

An update.  So far no recurrence of the cascade of warning lights. The car is not in daily use so perhaps still early days and I would be somewhat incredulous if a simple reset of the tyre monitor has solved the problem.  We shall see!

Further Update

 

Well after 3 months with no recurrance the problem is finally back with avengence.  On pretty well every trip now all the above warning lights are now coming on so I booked the car into my local trusty Skoda dealers.  They have confirmed, as predicted by Bexhillian and Brookfold1, a failed NSR ABS sensor.  However, they are quoting £402 to fix for a new sensor (£68) and wheel hub bearing (£135) plus labour and including the diagonistic charge.  This seems a bit steep on the face of it.   I assume they have deemed the ABS ring  also to be knackered hence quoting to replace the whole wheel hub bearing assembly.  Anybody know if the ABS ring is replaceable separately?  Parts seen online seem a good deal cheaper but may not be OEM.  Anyone have some useful input?

I would imagine the hub ring could be cleaned up with some type of sandpaper around the surface i had similar  about 2 years ago, tried to take off the brake disc but couldn't i have a 4 x 4 but by tilting disc and rotating hub managed to clean it up, no probs since although now have some replacement sensors just in case!

Sorry, nothing useful, save my ABS Sensor replacement was a 'take a seat, have a coffee, it'll be fixed in a jiffy'.

No dealer comment that any other component was replaced.

Done under my 5 year warranty, so no paperwork to me as dealer billed the job to Skoda UK.

Fault free since.
