Girlfriend has a 2015 VW Tiguan. 8th digit of vin is X. Engine light came on, took it to Oreilly’s and got a cylinder misfire on 2 & 4. I replaced the spark plugs and swapped the ignition coils to the opposite cylinders. Still the same error, same cylinders. Took it in to the garage that worked on my car’s brakes for a good price but really unsure about this quote. What do y’all think?
Bet the injector isnt even the problem. Usually misfires like that are carbon buildup on the back of the valves. Direct injection issue; no fuel cleaning them. I’ve seen it quarter inch thick in there.
