The-Mortman 0 Posted August 3, 2005 Not being known for my mechanical skills and not being able to buy an idiots guide, could any of you more experienced C owners provide a 'how to ..' on replacing a faulty ABS speed sensor. VW assure me its the near side front thats duff. I have already purchased the offending part from the WWW but could do with a few tips before taking the wheel off (which I assume is the first step .. or do you jack it up first, I can never remember :lol: ) My C is an M plate VR6 .. if that matters Quote Share this post Link to post Share on other sites
Supercharged 2 Posted August 3, 2005 If the sensor is original it can be an arse, they tend to rust/weld themselves in, PlusGas is very useful... as is removing the carrier and disk to get a bit more access, the sensor itself has a plug onto it you remove obviously and one screw/bolt holding it in IIRC.

h100vw 0 Posted August 3, 2005 I recommend that you plug the new sensor into the loom. If the old one is duff the light will now go out. I had this on my mk3 and it was the sensor. Before I ripped into it though I had to know it was the right thing causing the fault. I took the wheel and the brake disc off for access. 5mm allen key for the bolt. I didn't bother with any penetrating oil, I just knocked the fcuking thing out with a big screwdriver and hammer. :lol: Clean the hole out with a file or something cos I doubt the new one will go straight in. Maybe an hours job from start to finish, Gavin Quote Share this post Link to post Share on other sites
Joe M 0 Posted August 3, 2005 Im doing this tommorow, ive sprayed the sensor/bolt with wd a couple of times over the last few days. There seems to be plenty access with the wheel turned to full lock so if the bolt comes out first time it should be a 10 minute job. 8) I reckon theres 2 chances of that happening though...

The-Mortman 0 Posted August 4, 2005 Joe let me know how it goes .. I reckon I'll have a bash this weekend Gavin, thanks nice idea I doubt I'd of thought of that then it would have been too late Super, sound advice, thanks. Quote Share this post Link to post Share on other sites
Joe M 0 Posted August 6, 2005 Just finished doing this, bolt came out easily but the sensor was lodged in there pretty solid so had to take the disk off just as Gav said above. Easy enough though. Quote Share this post Link to post Share on other sites
fla 9 Posted August 7, 2005 How simple is it to remove the disc and are there any torque settings required? Quote Share this post Link to post Share on other sites
MoonlightVR 0 Posted August 7, 2005 How simple is it to remove the disc and are there any torque settings required? It's easy mate. Take the caliper off (2 bolts hold it to the carrier) and then remove the small cross head screw that secures the disc to the hub. Screw may be difficult to remove so worth using an impact screwdriver or similar to remove. Quote Share this post Link to post Share on other sites
fla 9 Posted August 7, 2005 Cheers Asim. Do you need the caliper windback tool for this (which I dont have) - i assume the brake pads will fall out too? Quote Share this post Link to post Share on other sites
MoonlightVR 0 Posted August 7, 2005 The pads will come out, but you won't have to wind the piston back as you're putting the same pads back in. Quote Share this post Link to post Share on other sites
Joe M 0 Posted August 7, 2005 I just took mine off at the carrier, 2 17mm bolts at the back then the caliper/carrier and disk will lift of and go back on as one. Quote Share this post Link to post Share on other sites
