Estimated lifespan of my B7?

I purchased my 2007 B7 A4 2.0T three months ago and it had 99k miles. It now has 103k miles.

My question is how much life can I expect out of the car? I've heard many horror stories of catastrophic engine damage due to shitty Audi oil design (mine burns oil too, got my first low oil light after driving 3000 miles). The pictures attached also show my pistons covered in carbon (haven't been able to check my intake valves yet but am unsure of that too).

My point is that I don't want the engine to break and lose all the $ i put into it. If I stay on top of oil changes, what is the estimated lifespan? As long as I can get another two years out of it, I'm happy.

I plan to check:
1) Carbon on intake valves;
2) engine compression test for damage to piston rings;
3) ?

Any feedback appreciated.


p.s: I LOVE my car, but not enough to shell out thousands for engine repair if pistons or something fail.

There's a bunch of people on their forum well into the 200,000+ mile category. Take care of the car, do maintenance and you should be fine

Just stay on top of oil and cam follower

Hmm those are good suggestions, not sure what your oilchange interval is set to but if you have vag com set it to 5k and not 10k, that will make it so your changing the oil more often especially considering it's a turbo car as the turbo cooks the oil. Make sure to cool off the turbo after any hard driving (some easy low rpm driving and idling before shutting the car off) don't excessively idle it when it's cold but also don't just turn it on and go, start the car, wait for the engine to calm down on its own then go. It doesn't do this in winter so 30seconds to a minute is a worthy amount to warm it up but don't idle it for five minutes (this is in regards to any car) as it will lead to cylinder scoring and flooding the oil with gas.

If you wanna go hardcore, cut the balance shafts in the oil pump, get a fluidampr and if you can pull the crank and have it balanced. It's the balance shafts failing which seizes most of the engines on here. Don't be redlining the thing and as a good basis don't take it over 5k (the balance shafts spin at double crank speed so redline, 7k, is 14k on the balance shafts which have non replaceable bearings/journals whatever)

Don't fall behind on maintenance, trust me, very quickly it will get out of hand and you will spend twice as much as the car is worth

Has the timing belt been done? Do it now if it hasn't.

Just take car of her, baby her and it'll take care of you.

Oh and do the carbon cleanings, you can live without it but you really shouldn't as it can excessively wear the valves because dust is always stuck to them sanding them down

There are many 200k+ vehicles on here that have been tuned since 50k and are beaten on regularly as well though and they last just fine. But it comes down to the owners and how much they obsess over maintaining the car.

I have a 2006 A4 6 speed MT with 260K- all original including clutch- I also have a 2007 that just turned 180k (daily driver) with a 6 MT- does that give you an idea on the lifespan? I do oil (mobile 1 0/40 every 3-4k religiously) and stay on top of the posts here- as in TB and cam followers......

There's another dude with original clutch and he's stage 1 since 50k and he's at 267 that's crazy how reliable the clutch is lol

I think that is me. I have 269k miles and still on the stock clutch. Never had a carbon cleaning, but I am finally due. And I have been Stage 1 since 15k miles.

WOW! Why now?

Im about to do mine in the next month or so. 90k and never been done (to my knowledge). Hoping it will make a noticeable difference

I used to do a lot of driving for long distances and drove the car much harder. For the last 75k miles or so it has been shorter trips and not driving the car as hard as I used to.

Hardcore man yep that is you

I cant believe it was from 15k as well. I'm just dumbfounded that you both still have the original clutch how!!

What kind of clutch you have?

My 08 is at 152k miles and is also on the stock clutch. I bought the car with 144k from someone who took great care of it.

Tiptronic ...........[:p]

Yeah carbon clean is a very good thing to do. I have done mine twice. First was about 12 months ago with unknown history, they were bad. Again I did this about a month ago, and again bad. Cleaning the valves really awakens the engine and the exhaust note at lower rpm is very deep.

Damn it built up that much in a year? Do you drive the car hard? How many miles did you put on it? How do you drive the car?

I've been meaning to get a catch can but I dont have the $$$ for it right now and my carbon cleaning was done about a year ago.

Glad to see someone else changes the oil so ofte. I use Liqua Molly 10w30 since I live at High altitude change her every 3K!

How long the car last will depend on how hard you drive it. If you baby it and drive the car nicely, stay on top of routine maintenance, keep it stock and use oem Audi-branded parts then the car should last you a lifetime. If you sense the slightest itch to mod then go slowly and moderately. Only things you'll need along the way are wear/tear items - such as belt(s), brakes, tires, mounts, shocks....other than that you're good.

I took photos but for the life of me I cannot find them.

I am almost at 150K. All stock. Running great. Still on the stock turbo.Change your timing belt and fuel filter if you have done yet.

All stock here too. see my sig below. Talk about timing belt and water pump, I just hit 65,000 miles. Will probably tackle them in the next 10K or so.

[emoji1303] just did mine a month ago at 48k

I did every single part though, some of it looked near brand new! I just didn't wanna take the front end off again haha

Way too low miles for that type of service, no?

With a car that is 12+ years old, it's better to change the timing components regardless of mileage

True. I didn't read his sig. Speaking of which I have a 2008 (July 2007 production) and just hit 65,000. I better giddy up, no later than 75K.....

Yea,what a difference in all-round performance doing that makes !
Then follow up with Suburu SA549 upper engine cleaner.Doing this every other oil change might not add much to longevity in this engine ( does in Subi's ) but regular,think half of VAG interval,oil changes do....IMO its mostly about that,clean air and watching out for the few known issues.

You should--you're closing in on 10 years now.
