Right car all back together, MAP sensor, Temp Sensor, Front Pads/Discs, Fuel Filter, Glow Plugs & Drop Link all replaced, had brother in law look at it (his garage specialises in VW among others) and upon starting the engine his instant reaction was 'oh shoot, you bought a bad one'. As you can imagine my heart sunk, especially after spending a little bit on parts, his gut instinct is cams on their way out, which for 179k is very plausible. Obviously not a disastrous problem, but not sure work will do that one without charging labor as its not a straight forward job like the other bits. He reset the fault codes and none came back so thats a bonus, still not taken it out for a drive as the cam issue scares me a bit as he said it could last 10, 1k, 10k or even 100k (although doubtful) before it goes. On Tues I will ask if they will take the rocker cover off and look at the cams as we didnt have time today, if they are gone then will have to decide what to do, sell and recover my costs or do the cam (money permitting). I know you get what you pay for, but obvs on a budget, are the chilled cast ones on eBay safe to use? My brother in law said they only fit parts supplied VW so he wasnt going to comment on the cheaper ones.
