ABS and SERV light stay on

Laguna I - 1.9 DTI 1999

Following a weeks holiday I jumped into the car this morning ( having stood for one week while I was away ) and the SERV light and ABS light come on as soon as the car starts to move.

The brakes feel fine , any suggestions on what to check before heading off to a garage ? , can worn pads cause this problem ?

Many thanks for all replies in advance

Unfortunately the only thing that the warning light is indicating is that there is a fault in the ABS system somewhere,it's not worn pads.

Ideally you need to get the car to a decent independant garage to read the codes of the system and this will help you find the problem.There aren't many aftermarket code readers that can read Renault ABS systems correctly,but if you could find a local Renault specialist that would be your best bet.

I'd rather push my Alfa than drive a BMW....

Try checking the ABS fuse for a start. Also, have a look at each corner of the car, there should be a push-in ABS sensor on each wheel hub. Check that they are all connected and that the rings are all in tact. Had this problem with my clio, turned out to be a dodgy sensor.

try braking really hard to see if this will clear the fault. try to get the wheels to lock (it worked on a Seat I used to have) it never occurred again!

Not a very clever answer but it worked for me

The F704 seems to work pretty well. Your ABS control unit reports the faults. The FR704 only reads those stored allowing you to home in on the fault. Strongly recommended.
