Hello all, I am new to the forum but not new to audi.
I recently acquired a 2007 Audi A3 2.0t from a local auction.
It needed a clutch but ran fine from what I understood.
I got the car delivered and no brakes at all.
I replace the clutch and do some needed maintenance, but now I am in need of help with the brakes.
I have replaced the vacuum pump, tested the one-way valve, and replaced the brake boost but i still have a rock hard pedal like driving a car will no power assist. I bleed all the wheel and still nothing. I pulled the code using a VAG scan and go an ABS code "01276-ABS Hydraulic Pump (V64) sporadic 01 2-Electrical fault circuit"
I checked and replaced fuses abs cleaned grounds under battery. Not sure where to head next. Any help would be greatly appreciated
