What Caused Recent Check Engine Light? - 2015 Audi A3 Long-Term Road Test


No one wants to see a check engine light. When the CEL illuminated in our 2015 Audi A3, seemingly without cause, we made a trip to the dealer for the diagnosis.

If I were to go to a dealer for a service it should include these checks each time: Hoses, Belts, Fluids, Steering & Suspension components. Most of these are visual checks and don't take long, Total labor should be no more then an hour and parts should be less then $100

you might also check into a bluetooth obd2 adapter and whatever phone app would work best. i used torque for android and a $15 (or less) bluetooth adaptor for the obd2 port. read all my bmw codes. and it resets them, too.
and i used the free version of the app. saved me $60 at an indy repair shop. i went ahead and bought the app as thanks. less than $20 i think...
In Year 2 it was jittering so the dealer had to replace some parts in the engine.
In Year 3 the dealer replaced the whole engine.
In Year 4 the engine light goes on.
My car's spent more time at the dealer for non-service related issues than with me!
Time to get rid of it.
