How many miles can an Audi engine last?
 

I know this depends on a lot of factors and "high-mileage" seems to be a relative term in the forums.

I ask the question because my 01 A6 2.8L has 215k on it. I bought it at 213k because it's super clean, was in my price range and runs great as of right now. The only code it throws is a P0420 when I run 91 instead of 93 octane.

So I'd like to hear from anyone who has more than 215k on their Audi, partly for my peace of mind, partly to know what Audi engines are capable of.
Btw, I found an Audi high-mileage club in the UK, with the record held by a 1998 A6 TDI at 439K! All the other vehicles that came close were also TDIs.
So how long can my 2.8L 30V engine live (not counting a total overhaul)?

the 2.8 is the most reliable engine audi has put in the c5 a6.
if you do proper oil changes and tranny oil changes and timing belt the car should easily do 250k given there are no current problems now. ive seen some 2.8's on ebay with 280k and used engines with 250k.

mileage is such a terrible way to measure an engine, there is a reason aircraft engines are rated in hours and not miles........

My 01 A6 2.7t has 216K...
 

Proper maintenance makes a huge difference, as does the way the car was driven. The PO had everything done by the original dealer up through 199K miles, and it was highway driven all it's life (PO was in some kind of sales.) From Michigan, so there's some corrosion on the exposed metal, but not bad. I expect to drive it until it drops, may try for 500K - hey if Mercedes can do it...

We traded our 99 2.8 for an 05 about a month ago. The 99 had 315,059 miles on the original engine and transmission when we traded it. The car was in very good condition at the time of trade, but timing belt was due and Mrs 4D4 wanted an updated look.

We traded the car at Coventry Motorcar in CT. The tech did the belt service and is driving the car as his personal vehicle.

Its all based on maintenance and hwo you treat it. But overall, they are very durable motors, with a few exceptions. The 2.8 is among the simplest and least stressed. 3.0 "not so much"

Change oil
Drive easy when cold.
njoy for another 100k

If you're not blowing smoke, or low on power or???? it should be good to go.

Service the tranny (dont flush, service)
pay attention to the timing belt service, including all rotating parts that touch it.

My 2.3l I-5 went > 300k and ran mostly like new even then.

Thats all encouraging to hear. I'm definitely shooting for 300k.

I plan on changing the timing belt and all other related items with a blauparts kit once I get the money set aside. Btw, I feel like it has lost a little power. What more should I check for during the timing belt replace? Or could it just be the aging Cats? No smoke in the exhaust, and it doesn't use much oil.

Beware of timing belt kits. There have been some customers with premature wear on the serpentine belts that came as part of a kit.

OEM is best for longevity. Continental, for example, does belts for Audis, but their non-Audi branded parts are the same but cheaper.

Do a little searching on these forums.

As part of your timing belt service you should check the key on the crank sprocket for damage.

Your problem is not the cats.
