Morning Guys,

Last night whilst driving home from my folks house the car entered what I think may be the "Limp Home" mode. I say think, because if it was called "Get you home as slowly as possible mode" Then I would be sure it was
Switching off and starting again clears this and it drives fine afterwards, but give her a good seeing to and she will regularly enter this mode. So I did that just before getting home and then connected her up to VCDS whilst still in limp mode (No lights so wasn't sure if a code would still be there!)

Here's the auto scan I got:

The rest of the scan came up with no faults, so only the pertinent parts are here!

Had a look on the Ross Tech Wiki and it talks of either the N75 boost controller or hoses. The three times I've had this happen I have been properly giving it some. General daily driving with overtaking doesn't activate limp home just continuous hard driving.

I noticed on another thread for a Golf Mk5 that the VNT turbo was also mentioned as a possible failure?

Will be taking it into Audi at lunch time hopefully, as it's still under their warranty, thankfully as it seems to spend more time in there than with me but hey ho!! Was just wondering what people thought could be the likely cause?

Cheers in advance for your help
