Why did my Audi not start after changing the valve cover gasket
Did you disconnect the battery if not may have blown a fuse, look under dash and hood for the fuse panel and check and check all electrical connection were put back together tight and recheck your work.
If you didn't touch anything while you did the work then its a separate issue you are having it may have just happened at the same moment....
It was the master engine control fuse 20 amp, driver side panel
One reason its best to unhook the negative battery terminal before doing repairs.
