Get it checked over, could be a number of things. The ABS system really just consists of an ECU controller, a pump and sensors. Sounds like its either the pump or the ECU. Doesnt mean they are knackered could just be a fuse or relay. If its the pump then a new one is about £1600, second hand between £400-£600 ECU is about £900 new and £300 second hand. Get someone who know what they are doing to do the diagnostic stuff, i didnt and it ended up costing me £1000 to get it sorted.

Any who needs ABS, if i was to do it all again i wouldnt bother.
 
Take the bulb out for MoT?

Surely you can remove ABS if you want to? After all it still (to my knowledge) isn't a legal requirement on new cars and it certainly wasn't when 944's were new. I have wondered about taking it off the Turbo although I'm not sure it would benefit in any way. If it comes up u/s when the car is back together I might explore the possibility though.
 
Both right, which is why I suggested taking the bulb out. You'd have to take 2 out though I think as probably the big dumb (because you can't cancel it once you've seen it) red light comes on too.
 
Direct quote from MOT tester

" If ABS is fitted, we have to ensure the warning lights illuminate correctly when the ignition comes on, and extinguishes correctly"

As I said, Faulty ABS = no MOT
 
Intionally disabling ABS for track use is another matter.

We used to fit a switch in line with the brake fluid level sensor. If the ABS computer thinks the brake fluid level is low, it will go into bypass mode. ABS is normally enabled, when you get to the track and want to disable it, just flick the switch.

HTH
 
Good point, they need to see the light come on with the ignition.

I still would have thought you can remove it completely though (and declare it to the insurance company).

ABS is NOT tested for an MOT.

See above. I suggest you consult an MOT testing station ..... and your insurance ..... I'm pretty sure that disabling ABS on the road would count as a modification ....

Having a shunt where ABS was obviously not working (traffic division are very clued up on that ...) would make for an interesting claim subsequent to investigation.
 
Absolutely it's a mod and you'd have to declare it, that was what I said. My point is that it shouldn't be an illegal mod like removing your seatbelts would be.

Anyway it's all hypothetical since I'm the only one talking about removing it and I'm not seriously considering actually doing it.
