Limp mode + Blown fuse

[smokiebbear]

Hi Everyone,

I have a 2009 VW TSI 118 Comfortline and it's blown the 10a fuse under the bonnet that appears to run the supercharger.

Engine fault light it on (orange) and it won't rev past 3k (limp mode)

The following issues are .....

G Scan tool diagnosed

P10AC Supercharger - short circuit to earth
P10AD Supercharger - open circuit


It has 109,000km on engine, it's not making any funny noises and the problem occurred when I parked it in my garage the other night it (free boosted in neutral at idle) and I shut it down then it dosed off and fault light came on.

When I replace the 10a fuse it blows straight away. When I put in a 15a it blows straight away. When I put in a 20a fuse it starts building boost through the supercharger at idle (900rpm) and there is a loud clicking noise as if something is trying to engage/disengage. I have left the fuse out and currently driving around in limp mode.

I'm thinking it might need a new supercharger magnetic clutch which I believe is engine out to replace (part of water pump).

Has anyone has this issue before and what was the final outcome?

Whilst I do appreciate people trying to help I'd much rather not confuse myself more with people who know less than me about cars or are just guessing what may be the issue I find are generally in fact more of a hindrance than helpful.

Please only comment if you have previous experience with this issue/one similar or may know what it is.

Thanks in advance
