hi , on my mk4 golf my ABS light coems on everytime teh car is started and beeps, will it pass its MOT with the ABS fault and also if there is an airbag fault will it pass???
-
Nope, if the light is on it a failure.
-
pull the bulb out :cool:
-
so it iwll fail for the ABS warning but what about the airbag light???
-
pull that out aswel :cool:
yes mate that could fail it
-
Instead of messing about with bulbs and stuff, you could actually attempt to fix your ABS. It is relatively simple, being this is the problem. Wheel speed sensors located around the hub are magnetic. Over time, brake dust that contain metal contents will stick to the Wheel sensor as it's magnetic. This buggers up the the sensor. Easy way to fix this problem is to clear that crap off the sensor, all 4 wheels.
This is a common problem, happened to 2 of my cars for this exact reason. Its at least worth a try eh :wink:
-
Could also be a loose or broken wire to the sensor on the hub so check these as well.
For the airbag I had an A4 that lit the airbag warning light which the guys at the garage reset at every service. They did this by removing the module that was under the seat in the A4 and cleanning the contacts and it reset. Might be a similar setup in the MK4.

roughly how much should a new sensor cost plus fitting costs? ive been quoted £150
-
i got LEN405 to help change a ABS sensor on my mk4 recently (front left wheel)
Part cost £10 from ebay and about hour or so labour.
There is a really good thread on this forum with pics and everything.
Oh yeh, after changing the sensor, we realised that when i had car fitted with lowered springs, the wires that conected to the sensor
were not clipped prperly into place, so the front wheel was rubbing on the wheels and snapped, So did not need to change sensor really
But only noticed this after the hard work was done

hmm, i dont feel confident to do it myself.

If you feel confident enough to jack the car up and change a wheel, you'll be easily able to change an ABS sensor.

Thread here! (http://www.golfgtiforum.co.uk/index.php?topic=57396.0)It's for a mk3, but it will be pretty much the same. :smiley:

an air bag light is not a faliure. god if every car that came with its air bag light on failed i would be a rich man. vosa do not seem it fit to use as a faliure. but ABS is correct it will fail but like what has been said clean the senors, then here is main dealer trick we used remove both battery terminals hold them togehter for 5 mins this removes any fault codes stored, do not let the terminals touch the battery. and light should go out.

cheers for the link, had a look, but being 6 months pregnant not sure im gunna be doing that! do u think 150 quid is a rip off, should i go to another garage?
-
£150 bloody rip off 20mins work and £35.00 for sensor includining diag, would charge £80.00
-
yea cheers, i got the feeling i was being ripped off. grr!

Oh, and on the subject of pulling bulbs out, I was looking at old MOT certs for my car and it failed once (before I had it) on "ABS light does not illuminate" as well as other things... so I guess it depends on the tester as to whether they check the bulbs illuminate for the self-test when you start the car, but you shouldn't rely on pulling the bulb getting it thru the MOT.
-
My mums car passed with the ABS light on last month. How did that happen ? I can't remember what she said, it was mentioned but nothing was done about it. It's been on for about 3 years now and I think it has passed the previous tests too!
-
Its a bit of sod but as the first of august when printing out the test sheet it gives you the sequence of the ABS light from turning on igntion to starting engine this is cause every car is diffrent, on any VAG in should be on then start engine and go out after 6 secs. any diffrent and it will fail. a quick dia scan will pull up fault code on abs
