ABS & SERV Warning Lights on Renault Clio
My wife's 2004 1.4 Renault Clio appears to have a fault
with the ABS braking system as the ABS & SERV
warning lights remain on once the engine is running.
Before I spend a fortune with a main dealer I wondered
if this is a common fault, perhaps a failed wheel sensor
that I could identify and replace myself.
Any advise would be much appreciated
A diagnostic check with suitable equipment should pin point the problem. You can find good independent garages with the equipment to do this cheaper than a main dealer.
Depending on your ability, you can check the sensors physically for any damage or contamination. Also check the stator rings on the driveshafts for hairline cracks (the rings are pressed on to the shafts and can split), damage and contamination. A CV boot on a driveshaft may be split and grease may be all over the sensor/stator ring.
If you have a multi-meter you can check the resistance of the sensors. If you need this, reply, and I will find the expected values.
As MrDanno says, you do NOT have to go to Renault for this repair - many garages do this work a lot cheaper.
Many thanks for your time and trouble in replying, I will certainly examine the stator rings for damage as suggested. I do have a multi-meter and a good friend who is an electrical engineer so if you could advise the resistance value fo the sensors we should be able to see if any are faulty.

Why is it that when we take our cars to the Dealer we bought if from, they always seem to charge more than other garages?
It is the main dealer 'rip off' Usually people will take a car to the main dealers because of the warranty and then you have the other people that believe that only main dealers do a proper job.

Front wheel bearings are a bit of a weak point on Clios so check for any play in the hub.
And check all ABS fuses are okay.
