That’s great to get so few on a 30 minute commute. Sounds like it was fixed like you said. Thanks for keeping us updated with the progress and fix. My average is up to 7-15 on all cylinders for the same commute time. Still makes me wonder if it’s “normal” like everyone is telling me...

Great! Is that after a whole drive or after a cold start only?

Happy to hear the fix helped. And by the fix, do you mean your cat or the problem with the camshaft? Just curious. 7 misfires is nothing compared to what my engine logs. My engine still logs misfires on all cylinders once warmed up. Anywhere between 3-20 per cylinder. No pattern what-so-ever...

Turns out they’re going to replace the brand new turbocharger with another one after running it through ODIS.

Update: New turbo didn’t fix the P00AF wastegate actuator error. Car went into limp mode on my way home from work and when I scanned it, there’s a pending P00AF code. I’m stumped as to what would cause it. Faulty ECM? It’s a brand new turbo...

Sorry to hear that. Did your engine misfires ever trigger a CEL? How many misfires were you getting and how long was it going on for? It does seem strange it would ruin the cat so quickly. My engine still misfires pretty regularly on certain cold-starts but never throws a CEL. Hope it doesn’t...

Interesting and good to know. Not sure how I can use that info to help diagnose the issue I’m having, though. Everyone seems to be stumped, both at Audi and the specialist techs. They both seem to think everything is fine as long as no codes appear. My fear is something slowly happening over...

Yeah, not easy to justify after spending almost $8k on an engine. Bit of an update to anyone following this thread: New turbo was installed. I picked up the car today. No more wastegate actuator code being thrown now, so that’s solved. So far did two cold start tests where the car sat for over...

Turns out I’m not having very good luck with my car. It’s back in the shop for another major repair after buying a new engine... I have to shell out $2800 for a new turbo (installed) because the wastegate actuator is intermittently malfunctioning, putting my car into limp mode and giving me a...

Wow, that’s worse than I was expecting to hear, I’m sorry. Sounds like you are going through some pain with your car much like I have. At least they were able to actually find what was causing it on your engine, unlike mine where the pistons mysteriously got damaged and I had to buy a whole new...

Hey @Damo S, any update on your issue? How was the A5? I was loaned the supercharged version once. It was nice, loved the instant throttle response.

You should still get a borescope done from another shop just to be sure. I’d be curious to see what they find out. Update on mine: The shop who replaced my engine kept the car for a day and overnight and did some VCDS logging. They sent in the log files to APR and an Audi engineer to check...

Figure out what the issue was or make any progress? Mine is still misfiring. Seems a little more now. Going back to the shop next week so they can see if they can replicate the issue and log it with their tools. They asked me if the misfire counter goes up rapidly all in a row like “pop pop...

Reason I don’t trust Audi so much, is Audi did a borescope test on my damaged original engine. After they did it, they told me I needed a new ECU and injectors. I did just injectors. Didn’t fix it. Had second opinion by specialist done, and their borescope showed pretty worn pistons and...

Possibly. What’s it cost to get them changed, - couple hundred bucks? Might be worth it. Curious though, what’s garbage about them? Is there an upgraded one I can replace it with or just replace with another OEM garbage one? Sounds like you’re not in the US. Not sure what US Premium 93 grade...

I’m thinking of replacing the plugs and gapping them down to to .026 to see if that helps. The tune could also just require time to adapt. I’m thinking that’s what happened after the stock tune was applied. Misfires were still apparent until two weeks went by. They started going down. Maybe the...

How many miles on your car? Was it tuned? If it’s within warranty and stock, I’d get the pistons inspected via borescope by someone other than Audi. Have them show you the photos. If there’s damage to the pistons and cylinders like my old engine, Audi should replace it under warranty. No...

I completely understand. I don’t see it as being negative! I don’t want another melted engine, either. The shop that’s helping me is one of the best in the state, and I guess I’m trusting them with their recommendations and course of action. They want me to monitor it as they don’t think there’s...

I could, but they don’t think it’s the ECU. They said other faults would show up most likely. They’re in the same boat as you, they’d rather rule out everything else, first. Thanks for thinking about me! The PCV valve was the first thing I checked myself. Took it off and inspected it and the...

Check engine light for the first misfire came on about a year after it was flashed. After that I flashed it back, and shop detirmined it needed a new engine after extensive testing. Bought and installed a replacement engine. No check engine light or fault codes have appeared after the engine...
