I don't see how replacing an ABS Unit seal would involve or affect a wheel sensor at all. Can you explain this OP?

It wouldn't -- but you're the only one that's mentioned a speed sensor in this thread

OK OK its "but the ABS unit sensor was damaged during the work (when the car was still in the workshop). " Whatever an ABS sensor is. As its not on the wheel, shouldn't have got rusted up.

The ABS sensor ops referring to is likely the brake pressure sensor in the unit.

I only have a basic knowledge of ABS systems.

But aren't the sensors on the wheels?

Of course if you put up which car and the age and mileage then more accurate help might be given.

Hi,

It is pressure sensor within the unit, not the sensors on wheel.

The car is 15 years old Mercedes, s class. For the broken sensor, the garage people says it is just bad timing or my components are brittle and easy to break.... I think neither of these two excuses are acceptable.

I have a relative you had a beautiful Peugeot 406. He took it to the main dealer for it's first cambelt change. The next day it broke and the engine was wrecked. The relative explained to me that it was actually his fault. He had asked for a cambelt change but hadn't requested that they change the tensioner and the tensioner had failed. He put in no sort of complaint at all and sold the car to a garage for peanuts. Garages get away with lots of things because people don't complain. I would tell them that if they don't sort it you will take it elsewhere and then take the bill to the small claims court and they will pay the court charge. Hopefully they would think again. As a compromise you could offer to pay for the part if they fit it.

thanks your advice

Things get old and parts corrode in place, the garage tried to renew the seal for you and it didn't work this time, thats part of the problem with running older cars and why main dealers don't get involved in repairing things and just fit complete new units instead.

If it was working properly before they had it you wouldn't have took it in for repair, hopefully a used unit can be found and the fix still fairly cheap.

thanks for your advice

Yes, that is correct.

They run the diagnose and the computer says the sensor is not functional. The damaged sensor is the pressure sensor inside the ABS unit, not the ones on wheel.

If it were a wheel sensor I think you would just have to pay the men, the damn things can be impossible to shift.

However this is a little different, they replaced the seal in or on the unit, now it is knackered. A little suspect, there is a good chance that they damaged it in some way.

Proving that is another matter.

The new unit is more than £1000 so I asked if it is possible to replace the seal ring to fix the problem. They are Mercedes specialist but they never suggest me not to do this or mention any possible problem may occur. And now the problem is not fixed, and they blame me because I insist to fix the seal ring instead of replacing the whole unit. and this is ridiculous!.
