Ok so last week my MIL light came on.. I was driving near the stealership and figured I might as well stop by see if they have the time to check it out for me.. but if not, book an appointment…. So today was my appointment.. (my MIL light went off mid Saturday) so I figured I better still come in and check what’s going on with my car…

So the service tech comes up to me and is like your car is ready.. Im like ok good, he sliek BUT do uw ant the good news, or the bad? Im like well how bout u give me both.. hes like ok the good news is theres nothing wrong *im like HUH? Hows there bad news then?* hes like well when we VAG’d your car, we notice a lot of codes popped up.. im like ok well…..?
Hes like its ok we just reset the ECU and they are gone, your cars fine now.. im like ok well can I get a copy of the codes that came up? *he hesitates and im like well? I want them so I know what the problem was..*

So he finally gives me a copy.. TWO PAGES LONG! I was like WOAH WTF????

Heres what I got…

Need to check my Bentley, but this sounds like you have a loose ground screw somewhere in the engine bay, or went through a *really* deep puddle sometime recently. IIRC, just about everything you mentioned has some part of it's system on the passenger side of the engine bay.

What year/engine/code do you have??

This looks legit - it's not the dealer's fault your ecu had 10 fault codes. They clear codes as part of the diagnosis to see if they return, or were truly "sporadic". The vag-com printout from the initial read is standard (according to bentley). I'm not sure I follow what the dealer did wrong - so far this sounds better than average. Some dealers would be trying to sell you a new MAF, Turbo, and Cat right now.

MAF causes all that? Keep us updated, I'm curious...

I'm in agreement with pete1. Sounds like you've got an electrical gremlin. I'd double-check your grounding and make sure that you aren't getting significant water in the passenger side of the engine bay before I'd go and spend $100's on a new MAF. May want to look for any significant corrosion.

Too bad the car can't log dates/times that events occured like a computer... :(

Yeah, that bugs me too. At least first time / last time / count, if not a full log.
