Hey,..
So ive been I contact with Nick a couple of times since I had this problem. I phoned Nick today with the intentions of finding out why and what happened with an added bit of attitude to compensate the grief and stress that I have had to endure due to the current predicament. As much as I would have like to say f**k you, you caused this, after haven spoken to him twice I have come to realise as hard as it was to except that I was the cause of this problem or at least thats how I feel right now(maybe ive been Duped).
Nick gave a detailed explaination to why it happened and as much as I wanted to pipe up down the phone there really seemed no need as the more he explained things.. At the same time most of it was common knowledge and some, Not all i already knew.
I surgest that When you do take your golf to a mechanic do so to one that knows alot about the Engine after all i did take it to a guy before this all happened who failed to find the root of the problem or so im lead to believe. Maybe it was just me being a dumb ass (ouch pride) but im taking a valuble lesson away. Take Notice of what your engine is saying to you and get it looked at stright away. Im aware that most of this is common sense but i consider myself some what of a smart guy and i still got burnt and Im definately not going to be the last guy either.
I have just spoken to my mechanic a trusted one who will also ring Nick today and just to comfirm that what i believe or have been told is truthful.

Hello Mate,
I have just spoken to your mechanic who is fixing your car, he now says its only 1 piston gone down? not more as suggested the other day? It will be cheaper to change just that piston? or has the bore been damaged aswell?
Number4 piston is the last in the line when it come to fuel delivery in terms of the way the fuel rail works which means its the first to fail when lean conditions set in.
IMO defo a lean fuel issues still caused the piston to melt as it has, You said you was well in to the red line close to 7000rpm on the dual carraige way, in the mapping the soft cut limiter is set to 6800rpm in the map you have on your ecu, what happens when the limiter is reached the ecu cuts back the fuel and load request to bring the rpm back down to the mapped limit of 6800rpm then start to load and fuel again, this can also cause lean issues and hot piston crowns & spark plug tips put normally not cause a piston to melt unless the rail pressue is not up the scratch, because if a leak pump, clogged filter or split on the fpr vac line.
Once the car is up and running again you need to get if fully check out by someone who can do logging on all the outputs and make visual picture of the reading. Bring the car down to us and I will check it all over for you on the dyno, I will educate you and show you exactly what is going on under the bonnet, I will show you how fuel scales vs boost, I will show you how lambda effect engine temps, It should be a fun for you seeing how the intense diagnostics is carried out, plus if your planning on getting vagcom I will give you a crash course lesson on how to do a data logging session amd make USE of all the number ect.. If money is an issues dont worry you can sort us out when you have replenished you saving at a later date.
Dont lose faith in the remap or car mate, I am 100% sure once you fully under stand whats going on and you have a vagcom lead it will never happend again... The harware in your engine is good enough for 300+BHP all day long and turbo is good for 240bhp max, with the fuel safe at a 250+bhp..
as long as the fuel is ok you will be fine, then you will be wanting to get closer to the 300bhp mark from a bigger turbo.
Keep us updated, your mechanic said he will give us a bell when its up and running, he need to invest in a vagcom lead so he can do data logging.
Nick
