Out of curiosity more than anything, does anybody know the sort of life expectancy (Mileage) of the engines in the 8P?

 

Was just wondering about it the other day. Must be a few out there getting on abit now...

If looked after & serviced when required using decent Oil the engines should last well over 100K miles.
However, one of the problems with the (8p) & other TFSI series (Apart from FL series) engines is inlet valve coking which will start to effect power output as the engine ages!

My first 8p (11) was sold near 90k miles and my current one (61) which I am keeping as a weekend car is near 83k miles. They are great cars that do require frequent tlc so almost like an investment.

Depends what you mean by life expectancy. If you exclude wear and tear items like sensors, pumps, clutches etc then with good servicing and driven well they can do 100's of thousands of miles.

 

If you mean a car only require oil changes, then a well looked after car can easily do 150k miles IMO.

Tbh it don't even come up on my radar mate.

It's not even really on mine tbh. Just with so few 8P's around it was something that I didn't really have any idea about.

All depends on how they are treated / Driven / Serviced / quality of service related items.

Watched an interesting clip of oem bmw oil vs Castrol Edge recently and the difference at higher temps of how the oils reacted was quite noticeable.

Am a firm believer if you treat the car right it should be ok for a long time.

The CEZB engines probably may benefit from a clean in the inlet valve tract / Valve backs once the engine gets to a bigger mileage.

Tell us some more or post the link about the oil mate.

Not sure how credible it is... but it does make you wonder.

I must remember that if my oil temp ever gets to 400*

It does make you wonder though if subjected to constant longer high temperatures would it make a difference to engine components though........

400* is well beyond the working temp of what engine oil is designed for.

 

The synthetic oil we use will start to degrade at 140*/150* so the 100*/105* we see in normal use is well within its working range.

As the oil over heats & breaks down it will loose it shear strength & you will then get metal 2 metal contact with accelerated wear on the load surfaces & the ensuing failure of components.

My point exactly Dell.

I like my oil changed regular.

At Combe last year the max oil temp i saw was 117°.

Short journeys with the oil not getting hot enough don't do the engine much good as it don't get hot enough to burn off the condensation & other by products in the engine oil from warming up.

Hmmm, hard one for me to comment on my RS3 engine died at 75000km and the car was stock ... another guy I recently met had his engine fail in the same way at 86000km, same piston 4 that went first and then rest looking terrible.

 

When he posted his frustration on facebook to Audi S.A we had a few guys actually coming on having the exact same problem with engines that failed between 50 000km and 90 000km.

 

So something is not ok with the cars here in S.A or it's something as simple as dirty fuel ,because when I got mine when I changed the fuel filter it looked like coke , this was fuel going through the filter before the filter the fuel was clean ... I also recall that my fuel trims was always in the double digits and this most likely killed the engine.

 

Now after the rebuild and them cleaning the injectors and fitting new seals etc the fuel trims are basically always single digits close to 0.0

Possibly unrelated, but my gearbox is being replaced at 45k. Usually takes at least a month for Germany to get a new gearbox here to the UAE, but after they looked at the gearbox data they’ve got it here in less than a week. They’re unable to tell me (or don’t want to), what the problem is. I also wonder if there is not a flaw that we’re not being informed about.
