A8 Timing out?

[Urbtree]

Ok so forgive me If this turns into a waffle but I guess you need the story.

Bought a 2000 A8 D2 2.8 recently. (picture in introductions)
after about a week it started making a noise that I attributed to a tensioner on the aux belt.

Turns out I got it to the garage just in time as the water pump had died and dropped water all over the tensioner below it causing catastrophic failure (loss of all ball bearings) and very nearly toasting the car.

I took it to my very competent tame mechanic who fitted a new cambelt kit tentioners water pump and rollers in just under 2 hours.

He told me with the bearing going he had no correct reference point so had to guess the belt position (possible misquote here)

I've since read about the special tools and about having to take the front end off to do the job.
I've also read a lot of posts on here that tells me this isn't uncommon.

Everything works fine and runs but I now have a lumpiness at tickover that wasn't there before.

We both suspect the timing may be slightly out and the VCDS log kinda confirms it.



What I need to know is
1. if I buy the special tools will that allow him to set it up properly if he has no correct reference point.

2. where do I get the tools and a ball park price if possible

The car does have one or two other issues but I'm kicking off here with the priority cases.

Thanks in Advance

Mike
