did this happen or not? 
No

Pity, because my brother in law could do with a face lift the ugly f@cker
so its fcuked then 
No, because it can be sorted with a little work
hopefully 
CQ want £400-£500 for head off and rethreading of the GP hole, this means timing belt change, head gasket change, retime injection pump and engine, change GP relay as this might cause the GP light to flash fooling you into thinking it's water in the fuel (although there could be water in the fuel filter too) drain fuel tank if required and blow out the fuel lines.
The question, is it worth it on a cat c ?

I tempted because as you've seen chuff the shell is pretty good (bar the small dents in the arse end).
DH, the problem is it's GP for cyl #1 which is right behind the IP at a b@stard angle, I tried 2 different GP's their threads are still 100% after going in and coming out and checking them over and I tried getting something in there to clean it but it's such an awkward place.
If I was confident in timing up the engine & IP I'd whop the head off and have CQ rethread the hole and refit the head myself, but I don't have the dial gauge or any tools to do it properly, as well as no where to do it.
EDIT:
Just had a thought, my uncle was trying to be helpful yesterday and only put 1 of the 2 cables that go to the GP Bus bar on and when we cranked her over they saw a flash from the GP relay cage area, so that's £30 to replace with a similar relay as the OE's for this engine are discontinued and were £75...
I might give try the GP another try with a tube of thread lock or if someone can recommend something stronger or more heat resistant, I'll give that a go.
So for the price of some high temp thread lock type stuff and a new relay, I might get her working again
Had a change of mind, £400 (or up to £500+) on a Cat C, is a lot of money! So looks like I've got a project, just need a place to store it until I can get the tools and do it myself!
I'll be looking @ newer cars sooner now, the Jetta 140TDI's are very appealing with the large boot space, Golf Plus don't seem to have that much more space than a normal Golf... The Sharan's are also appealing with the large boot space when the 2 rear seats are removed.
