Audi A4 1.8t random starting problem!!! need help
 

My car is experiencing a random starting issue. The car will turn over properly but just wont fire. If i let it sit it usually start after, or if i keep attempting to turn it over. This only happens once every so often and i just brought my car in to get this and some bogging issues fixed and now the starting problem has came back... anyone has solutions or ideas what this is ...?

Check the engine speed sensor. Mine had intermittent starting problems before
it finally failed and left me stranded. $300 installed at the dealer. It's trying to warn you maybe - mine was.
