I have joined here because of the Limp Mode issue on my Girlfriends MkIV, i've taken the Turbo off today to clean it all out and am dreading it
I have had a tentative go at removing the 10mm bolts and they're stuck fast and i'm in danger of turning the heads, i've left them to soak in WD40 tonight and am going to have a bash tomorrow.
The car has had an oil leak and I can see now that it's been coming form the Turbo so more investigation needed there too. Happy days!!
