Hi all,
I have done some searching for similar issues - however not found anything, so thought I'd place a post and ask for any advice or help.
I have an early Mark 5 Golf 2.0 GT TDI, it's covered about 63,000 miles, I've done the last 20k as I bought it second hand from a dealer in Camberley.
I arranged for the cam belt to be changed and a service to be done at the end of last year as I wasn't sure that the dealer had actually serviced it before I had it (from the state of the filters this was pretty much the case - but that's another story) Also had the water pump and pulley's etc. changed. I arranged this with a local garage who was recommended.
All was well! At Christmas I treated myself to a Superchips Bluefin as they were selling them with 20% off.
This upgrade went well and the difference was pretty noticeable. After a few thousand miles however the low coolant light came on. I topped it up and took it back to the garage for his to take a look - thinking that there must be a loose hose or something from getting the cam belt and water pump change.
He tested it and found no problems, but added some dye to the coolant to try and pinpoint the problem. Returned again for a top up after about another 2-3k miles and he had a book look around. He diagnosed that the head gasket was going and coolant was leaking into the cylinder, some white smoke and sluggish starting occasionally, confirming this.
Had the head gasket replaced. However I still have coolant loss, and there's no obvious reason. No residue on any of the under trays, nothing round the expansion bottle, as far as I can see no obvious white smoke or starting problems.
Just after the head gasket replacement I did get the engine warning light with Emissions workshop! as the error. On reading the code it was V157, which related to the regulation flap in the throttle housing. However this has now as suddenly disappeared.
Sorry for the history, but I guess it all leads to now where I have a car that I love, but is very slowly (about half a litre per 1500 miles) of coolant, where it's going I have no idea and the guy at the garage has spent many hours - at no expense - looking, and now says that the next step is a strip down of the block and a pressure test, which will cost £1000's. Having had a look the inherent value has considerably declined and I can't spend that now.
Anyone have any ideas?
Thanks Loui
