99 Avant 1.8T quattro (AWD). ABS light on. vag- comed. Got the code

1 Fault Found:
00290 - ABS Wheel Speed Sensor: Rear Left (G46)
35-00 - -

Ordered an ABS sensor (the same as the old one). Replaced the old one. Cleaned the code. Drive the car. The same code comes again in within one minute.

Seems not a problem of the sensor. Want to check the ABS rotor (ring). Looked into the Bentley manual. It seems only the bolt at the center of the wheel need to be taken off. It has an allen socket for my car.

But when looked at the car after taking off the wheel, many things a attached together. I am asking myself if I have to take everything appart. Anyone can tell me how to take it off? Furthoremore, what is the size of the allen
socket?

Thanks!

 

are you trying to get the roter off, I don't follow you.

 

Yes, I want to take the ABS rotor off, and I don't know if I only need to take off the screw in the center of the wheel.

 

you might have to get that allen from snap on, cause i went to the stealership and they didnt sell the tool[:@]

 

Youll have to take at least more than that off. Get a mirror if necessary and take a peak into the sensor hole. That will give you at least a partial view. Id say youd have do more than take out that bolt. For sure youll have to remove the other end. Probably one of the suspension links also.

 

Im not sure what you are asking, but to remove the caliper is two bolts and one line...maybe four for the rear cant remember, and the rotor comes right off, the only thing holding it on are the five bolts for the wheel. The center is a 12mm hex socket. You CAN get them at any auto parts store.
