4.2 2000 a8
OK
I am brand new (brand noob) to this
I don't even have an Audi
but I am buying a new car in the coming month(s)
and I am quite keen for it to be an Audi
I am most keen for it to be a A6 4.2 quattro (C5) I think at the moment (altho also have test driven a 2.0T Sportsback A3 and 2.7TT Allroad)
The one I am most interested in has "high milage"
Now, some engines you should steer clear of when buying 2nd hand if they have "high milage" for this discussion I will consider
quite high milage > 70,000 mile
high milage > 100,000 miles
very high milage > 130,000 miles
now, some engines I would (provided they had good service history, were running smoothly and "felt" right) have very high confidence buying even if they had "very high milage". Such engines would include Subaru EJ20, Nissan RB series and BMW 2.8L 6cyl. Other engines, even if the seller had a faultless service history, and no problems to date, I would consider ticking time bombs if they had "quite high milage" and some engines I would just strongly advise to not buy (or hold onto) once they reached "very high milage"
I currently drive a BMW (with that 2.8L engine, and it has about 112,000 miles on it, and still oozes confidence) and am lucky enough to have a good BMW specialist mechanic, but unfortunately this means (and I did check with him) he can not give me any advice on how this (Audi 4.2L V8) engine ages.
if anyone who owns one, or owned one, or services them, or is just generally aware can tell me what they know, and feel and why, that would be very appreciated.
Thanks and regards

Mind me asking how you cleaned your intake valves? Like did you run a cleaner through it, or took everything apart and literally scrubbed?

My wife drives a 2004 S4 Quattro Avant with 103k miles. Engine runs fine and has never been touched except for periodic replacements of consumables by Audi Service.
The most substantial repair we have had on the S4 was a set of coolant and oil leaks requiring replacement of the water pump and secondary radiator (coolant issue) and replacement/resealing of the front crank seal, resealing of oil pan, and replacement of oil filter holding gasket.

old thread, new data point
My 2001 A6 4.2 just lost it's transmission. Engine running basically like new. 261,000 miles.
Big events:
- new timing belts, water pump, etc. at 108,000 and 192,000
- left cam chain tensioner failed at about 200,000. Plastic ramps shattered. Dealer replaced the entire tensioner for big bucks
- right chain tensioner- I replaced only the plastic ramps, for probably $140 including gasket set, plus a Saturday afternoon
- plastic coolant tube in oil cooler housing replaced by the dealer. Around 225,000 miles. I tried, but there was one bolt I couldn't get, and had to reassemble and bring it in
- power steering pump at about 200,000, replaced by the dealer
- new Behr coils at about 200,000
In hindsight, I think right around 200,000 miles things started getting expensive.

Sorry being late to this dance..
It took a couple of years to locate my 99' A8.
Without a spotless oil filler port I would have kept looking.
Two years and miles of driving and looking, I landed a mechanically clean engine and luckily a straight body with cleanable interior.
After paying top dollar for this jewell in the rough, I replaced EVERY system on the car and flushed the trans two times. I have a great piece of transportation and would do it again if needed. This A8 runs well, gets excellent milage and has NO leaks.
From the radiator cap to the new fuel system, everything was replaced. Since I do all of my own wrenching, keeping the cost down was the departure point for buying this Audi. If I had to have taken it to the dealer I would have not been in a cash position to go this far with what at the time was a 12/13 year old vehicle.
I am a happy camper.. pc
It's been a few moons and FWIW, my little A8/99 continues to purr, like a kitten full of cream. Rebuilt , rather than replaced the front axles (broke boot) and the rear shocks. I continue to be a "very happy camper."

2004 Audi A8L D3 with the 4.2, just had the Timing Belt job done. As of today 164,586 miles on it, still runs strong and wouldn't hesitate to take it to a track.
