G201 brake sensor intermitent --> please help
I got error code and it's telling me that G201 brake pressure sensor intermittent. The car was normal and randomly, the skidding icon, Abs light came on, the middle screen said check ESP/ABS... then said parking brake malfunction. Turning off the car and they went away but pop up randomly after. Please help!
My car is 05 A6 3.2. The dealer replaced the brakelight switch but I feel that they did something shady. The brake doesn't feel normal afterward anymore. it's much higher from ground than before. They said if the light pop up again, ABS module will have to be replaced. I don't know if I should trust them.
Also,
1. I just replaced the font brake pad to ceramic pads, the rear are still original. Does that matter?
2. My left tires needed to be replaced and my right tires are like brand new. Could this have caused the problem? I just went out the bought two new tires. Both sides are even now.

there isn't a fix yet am_ver, I'm looking more closely at the G201 brake pressure sensor now. Some sources said this sensor is part of the ABS ECU but others sources said it's not. I'm going to Audi dealer to find out more information on that tomorrow. Hopefully it's just another seperated sensor and easy to replace.

After some researches, I found out that for our car, the G201 sensor is embedded inside the ABS module. Luckily, I was able to trace out a new unit for replacement. Also, the ABS module can be rebuilt for cheap. I would recommend heading to your dealer and pay the $125 diagnosis charge before touching the ABS module though.

Check it again. G201 is a sensor built in your ABS module. The dealer could have mistaken your car with the older C5 model where this sensor is completely on its on. I believe it regulates how much brake power to give each wheels.
Yes, my car also got the brake light switch replaced at dealer during that time. They charged me over $250. I was falling off my chair looking at the bill. I though part alone was 50-100 bucks and totally not worth my time crawling around replacing it myself but the actual price was like 7 bucks. Definitely bring it in, they will most likely tell you to replace the ABS module and the quote should be around $2700 total. I didn't rebuild mine so no recommendation on that. Maybe someone else up here did. If not, ask people in C5 or A4 forums, there must be someone there has done it before. Mine went bad over the winter time too, eventhough I didn't feel the car any less stable without ABS nor ESC on, however, do get it fix asap.
