Hi , has anybody ever changed any front parking sensors on a A4 b8 ? I've managed to get to the drivers side outside sensor through the wheel arch and fog light but I'm still getting a dead sensor . I ordered a replacement from eBay off a 2015 car and was told they're the same . They look physically different but have the same connection. When parking assist is activated ,no graphic appears and there is just a long beeping sound . Basically the car is no different . A small vibration can be felt at each sensor bar the faulty one and the replacement ,maybe a wiring issue . Does the car need to be code read to clear the fault Any advice would be appreciated . Thanks
