Disable ABS dash warning light?
Hi, ABS warning light has come permenantly on and I've got my MOT test in a few days.
Is there any way I can just disable the dashboard ABS warning light? I've tried pulling the fuse but that only lights up the brake warning light as well as the ABS light. I'll sort the ABS post MOT test. Thanks, Ali

Why would you want to disconnect the light to get it through the MOT it is a safety feature of the car?
It will not be that difficult to fix it |

If the ABS light doesn’t illuminate and go through the self test cycle on start up, then that is an MOT failure.

So either way, an MOT failure?

You can get it to mimic one of the other warning lights by desoldering the ABS LED and connecting it to the SRS LED for example, but as mentioned far better and probably easier to fix the fault. Plenty of info on here to help even those of us who can't pilot a plane. |

No easy way round this one, sorry - I've been struggling with it myself on and off for 2 or 3 years now, as different sensors etc start to give up.
You could wire the warning light to something like this, to switch it on a for a second or two then off - but probably no easier than sorting the problem out Use TOAF to tell you where the problem is, but I've had to have wheel bearings replaced and things

Isn't that somewhat missing the point of an MOT? Just imagine what would happen if having disabled the ABS light an accident was to occur followed by an insurer and/or police investigation. Is the risk of being locked up and bakrupt worth taking? Quote:

It's best you let your MOT test pass by and get your car on a T4, that should point you in the right direction, most of the time it's the OS rear bearing picking up some rust from the back plates. When is your MOT you may have time to get it rectified before then but you need readings.

Hia Arctic, thanks for your input. MOT expires 21st August. I've texted Brian but no reply so I guess he's on Holiday? Will try texting him again next week.
I disassembled the NS rear brake yesterday morning and blew compressed air into and around the sensor (I don't have a large enough socket to remove the hub). Tried to do the same with the OS rear this morning and broke a brake pad. Thankfully one of the neighbours was going into Hexham and bought a new set of pads. Will blow compressed air at the sensor tomorrow morning. Speedo works so it's not drivers side front. If it's the passenger side front sensor it's so encased in rust that I fear it'll have to be drilled out, not something I can do. Thankfully I don't 'need' to drive the car (I only go out once a week for shopping), but once the MOT expires, driving to Brian's will set off the ANPR cameras I fear. I've read the thread about voltage readings but I can't undo any of the connectors, locked solid and am afraid of breaking them if I try to force them. T4 would be best then buy the right part and then get the local garage to do it and then do the MOT. I think Brian is the only person around Northumberland / Newcastle with a T4? Local garage have tried previously with their computer but apart from resetting engine warning light, no coms. I've got TOAF but 'it'll only communicate with the engine module, it doesn't register any other modules sadly. No idea why, tried different computers and have the correct modded VAG-COM cable. Crazy. Fingers crossed that blowing air at the sensor tomorrow will fix the problem. . . . Ali.
