Nice 1 RR, glad everythings sorted pal. 
I've heard of turbo casings cracking before, not on the Tfsi as such, but it is fairly common on Cosworths etc

Great to hear that Red.

Are the revision G turbo's less prone to this cracking, do you know? As you have got me slightly worried with my Stage 2 now!

Keith also set my boost to 6 - but that was for fuel pressure reasons.

....Yep - she's a sweet ride again - I've just returned from a 322 mile round trip to the Open Day at APS where I met up with SteveP, Jamie in his modded S3, and a lot of Audi TT guys.

APS boss Ed, told me that hairline cracks were known in the K03's on the Mk4 but weren't always a problem.

Thanks for the well wishes :happy2: - I'm gonna start a new post in Troubleshooting/How-To which is a concise overview of my example discussed in this thread. The intention is that it will provide a resource of info for anyone with a K03 2.0T FSI engine in their VW/Audi/Skoda/Cupra etc.

....Your turbo is running sweet and JKM took their time to rebuild my Revo2 map settings and to check the logs.

Thanks again :happy2:

....Yes it could happen to anyone but such is the nature of cars and all their mechanical components. I don't think that because it's happened to me, it's going to happen sooner or later to everyone else - I think it's important to accept that such things can happen but Think Positive.

Great to hear that Red.

Are the revision G turbo's less prone to this cracking, do you know? As you have got me slightly worried with my Stage 2 now!

Keith also set my boost to 6 - but that was for fuel pressure reasons.

....I haven't had the chance to photograph my RevC version yet but Jim had a good look and couldn't see any obvious external difference from the RevG.

You don't need to worry unduly - Revo2 has been applied to a large number of different cars with the same 2.0T FSI and K03 and without problem. They assure me that boost 7 and higher should not create a problem. However, it may highlight a manufacturing defect or problem that's already there.

I'm not having any fuel pressure problems as such but my dyno plot is showing a very slight dip which would be got rid of if the APR fuel pump was installed - So it's very likely my next mod. It would just help everything run better and with less demand.

Keith really knows his subject doesn't he!

:happy2:

Nice one, although I sort knew from what went on prior to this I was expecting it to be a turbo related issue .. unfortunatley!!

....Yes, it was a process of elimination starting off with the easier things to access and check.

Be nice to see pics of the fault unit - just to see exactly which bit went wrong.

....I'll post pics when I get the chance in the next few days.

Suppose the weather doesnt help but does it feel any better now?

....In the last 48 hrs I've driven about 500 miles in all sorts of weather from dry and sunny to torrential rain and in daylight and at night. She feels great in all conditions and whether pootling in D, screaming in S, or flappy Manual.

Would you consider selling your old turbo ... wonder how much a recon would be ...

....Great as it would be to sell my turbo and recoup a little of what the whole problem has cost me, I would not want to sell anyone my turbo without first a turbo specialist taking it apart, repairing and rebuilding it. Just to take it apart and produce a report would cost around £200. It's not worth me spending £200+ and then waiting for someone who wants to buy it and also it's done 57,000 miles.

By part exchanging your existing turbo, VW can supply you a reconditioned (possibly new if you're lucky) K03 for about £650 and with a 2-year warranty. However, if your engine is at all modified, especially exhaust and/or remap, the turbo warranty would be meaningless if you subsequently had an issue.

Edit:  Also be useful to see your logs - boost graphs etc to see the difference now I assume it meets requested.

^^^^ You keep asking to see my logs - I don't have them - JKM do, together with about 200 other 2.0T FSI logs. Every car is slightly different too.

I'm now interested to see how your turbo problem gets resolved. My advice is not to leave it to possibly get worse and hence potentially create more serious damage.

Interesting to note that on one hand VW Racing who you seem to have great faith in don't recommend an uprated HPFP whilst JMK are trying to sell you one because of a slight power dip that you probably don't even appreciate when driving.

Decisions, decisions...

The standard fuel pump cant cope with the extra fueling requirements of the stage 2 map, which results in falling fuel pressure, which again will result in a misfire as pressure falls further. He would notice the misfire no doubt.

But yeah, good call Bacillus ....VWR seem to be very against improving the standard fuel pump, and i wonder whyyyy!
