Default 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?

Thanks

Default 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?

Ok that's not real high mileage. To remove the fuel rail there are 4 10mm bolts that holds it on the intake, disconnect all 8 connectors, and disconnect the fuel line on the rail and gently pull it up. Or you if you have enough room, you might not have to remove the fuel line connecting to it. The injectors should be held on by metal clips. Just simply swap the affected cylinder, and put motor oil on the o rings on the ones you're going to swap. Before you put the fuel rail back in, get some motor oil and coat all 8 o rings so it will make it easier to go back in and not have any leaks. Install everything reverse of removal and go from there. It's not a hard job to do. Hope this helps you.

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.

Yea its not. Sounds like you're mechanically handy. I hope that's the problem and works out for you. You could go on audiwholesaleparts.com and get one cheaper than dealer prices and a little cost for shipping. Chance of them being aftermarket is slim to none. Worth a shot if that's the problem. Don't buy one just yet until you do that test lol.

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