I think I’ve had and overcome every 2.5t issue imaginable apart from head gaskets and engine self destruction, although the PO was doing their best regardless.
I’ve dealt with all the minor stuff, successfully avoided the big stuff through research, moderation and luck.
Since everyone suffers similar issues as the mileage piles on, the same old questions keep getting asked.
So rather than post whatever I remember about solutions, I decided a few years ago to keep notes in faq form, and just keep adding info as I learn new aspects related to old issues.
I mean I was re-reading my old posts when I was just out of n00b mode, and I’m like, wtf? Is that actually me speaking? I’d completely forgotten things I’d thoroughly researched years ago!
Its practically a book of chapters now.
The avcs diagnosis post is an absolute MONSTER and there’s still stuff to add !!!
