Hi, a couple of weeks ago i was driving home, when a lorry drove pass and splashed a load of water all over my car. The car shut down and now wont start. I've Changed the 3 relays under the bonnet and the 80amp fuse but still nothing. The car will crank over but wont fire. It will start on easy start but as soon as that burns the car shuts back down. Its a 2007 A4 b7 Model. Any suggestions? Thanks
