Hi,

I have just bought a 2004 A8 3.0 TDI Quattro on 87,000 full Audi service history, but i have the chatter on start up, which my dad spoke to audi mechanics and they diagnosed it as the hydraulic chain tensioner on the left bank which is a known weak part. They quote 5-6 hrs labour with the job costing between £500-600.

My dad is a mechanic and i was wondering is this something we could do ourselves?

Any help would be great done a search on google with not many results.
