Hi!
To keep it short and sweet! G3 MKB->AFN, 1997, Disc brakes, Rear
I suspect that the ABS control unit has failed because both rear ABS sensors are showing as "present" and are also repeatedly appearing. When I replaced the rear brake discs, I saw the mushroom-shaped, worn-out sensors and immediately removed them with a hammer, as it was much easier that way!
Now that my budget allows, I want to buy 2 new ones, and the VW dealer is quoting €74 per piece!!! Well, I don't know... even the supplier says 50€ + fairytale tax...
Okay, let's move on to the actual question. Can't I just install the sensors from the G4 or something? They cost a fraction of the price, just solder the cables on and it's done!! I looked at some pictures and I thought that they should fit perfectly from the mounting (they look the same physically)!! Unfortunately, I don't have the dimensions at the moment! According to Autodata, the resistance values are the same... Maybe someone has a spare sensor (G3 HA sensor -> G4 HA sensor) and could compare them. Regarding the connection, I don't worry about it; we all know that the sensors also hold well
Okay, one more thing about the history! I bought the car two years ago and never had the chance to test the ABS, until just recently, when I realized that it wasn't working at all. The key thing is that the warning lights had burned out, and that's why I never noticed it before. Basically, the lights were always on (presumably because the previous owner had a problem), or they were replaced because they were defective, whatever the case may be...
I don't want to spend €150 just to find out that it was actually the STG...
Maybe someone has a tip for me.
