Misfire cylinder 7
My misfire happens whenever I punch the accelerator. I first ran some german fuel injector cleaner but this didn't help. My second approach was to swap the coil pack of cylinder 7 with cylinder 6 to see if the misfire moved with the coil pack. Nope, still a misfire on cylinder 7. I then called an audi dealer to get the part number on spark plugs and they gave me ngk 101905621B which I bought online. I just installed these plugs but I'm still getting a cylinder 7 misfire. VCDS is also stating 'random/multiple cylinder misfire detected' along with 'left engine mount solenoid valve.'
When I punch the accelerator with the new plugs my check engine light will flash a few times then goes off, with the old plugs the light would remain illuminated (not sure if this matters.) Could this be anything else other than a bad fuel injector?

Bad injector seems logical
Since you have diagnosed the spark plug and coil scenarios pretty definitively. I suppose it could be either a bad connector/wiring to the coil pack or a bad ECU, but those seem pretty low probability compared to an injector scenario as the next step. I would run another bottle of Techron brand fuel cleaner through--24 oz. given the fuel tank size, but at least the (larger) 20 oz. bottle, or else two 12 oz'ers.

I have another bottle of Liqui Moly fuel injector cleaner so I'll run that, I'm at about a 1/4 tank now anyway. I'll grab Techron next time. I sure hope this helps.

Just like what MP4.2 said the other logical thing is the injector. Since you already swapped the coil pack, the injectors in our cars are so easily accessible so you can swap those too. If the misfire moves then you found yourself a problem. How many miles do you have on the car??

The car has just under 94k on it. All I have for reference at the moment is a subscription to alldata. I haven't checked yet but just how easy is it to swap an injector?

That doesn't sound too bad at all. A new injector is not that expensive luckily, if it turns out to be the problem. I'll take your advice and see what happens, this problem has been hindering my attempts at spirited driving.

Have you done many injector swaps? Your description sound pretty simple, but it cost me near $800 at my Indy shop on my 07. |
