Personally I don't see 125k as much mileage.
The leak is almost certainly a split boost hose (very common) or a holed/split intercooler.
The boost hoses need to be removed to inspect as the splits can be very hard to see.
Yeah, the mileage isn’t much in the scheme of things but the increase in rate of deterioration is disheartening. The cosmetic issues aren’t financially worth fixing (although I wish they were, the paint on this car was not well looked after before I got it) and despite all the maintenance I have done, and parts replaced whenever there is a need, starting to think it may be better to save the £££ toward the next incarnation.
If I can get an indie to pull the boost hoses all off and find the leak this week then it would be good, else I may have a go at it next weekend (or later today is weather is good. I am also wondering if it is worth getting them to pull off the EGR valve for a clean while it is all off.
