The EA824, used from (in this case) the Audi S6, and all the way up to the Lamborghini Urus, and many other Audis, Porsche and Bentley vehicles in between, in various forms.
It is a very complex and jam packed engine, so even little jobs can take time.
This one (our own) has had a dreaded chain rattle, and having done live data recording, can see the bank 2 exhaust cam timing is out more than expected, but comes back into spec during startup. And always seems worse, the longer it's sat. So a couple good clues to work with already.
Now, this doesn't mean straight away a chain and tensioner, but we can't rule it out either. There are various check valves and solenoids, and also the complicated pcv setup that could cause this.
So we work methodically, proving parts are good or not. 1st port of call is the solenoids that supply oil to the adjuster (or phaser)
Keep an eye out as we progress. And fingers crossed, we won't need to drop the gearbox and do a timing chain!
