Hi all. So I have a 2003 ALH TDI Jetta. I have had it for 11 years or so. Obviously done things in the past. It's a bit of a high miler but not crazy about 415,000km (258,00mi or so). Any insight into what maintenance I should look at doing ? As I plan to try and keep the car for a while now. I mean other than routine stuff.
A bit of history I replaced the tranny and clutch around 350k. Timing belt was just done. I am cleaning the intake and replacing MAF this week. Going to have some ball joints suspension stuff done shortly as well, nothing major but I have a friend who's a heavy duty mechanic who will do it for me and there's some minor issues. I guess in short what else should I be looking at as a potential issue for longevity ?? First thing that comes to mind is the turbo. I get a bit of blow by and get some oil pooling the intercooler but drain it at oil changes and it isn't a lot. Last oil change there wasn't even enough to pull out with my suction tube I just sopped it up with a rag. Just let me know your thoughts! Still getting great mileage. Get limp mode here and there but not crazy often I'm hoping cleaning the intake helps that. Should I replace N75 valve ? Did it once before years ago. Scanning I have only one code it's a glow plug fault which I know I have a bad glow plug stripped in the head (for like 8 years now, just run 3 working ones and a coolant heater for cold starts).
Anyway thanks in advance ! Just at that point I want some advice on peoples experience and things to watch out for . Cheers!!
