Hey guys, Im new to Audis and DIY repair. I bought a 2011 A4 and shortly after the valves bent. I repaired the car and it starts now (after 5 seconds of holding the ignition), but the car shakes and has no juice at all when i drive it. The biggest code that popped up was P188700 (ABS) and im not sure if that is the issue going on.. would love any tips from anyone who has an idea of whats goin on. Thanks!
