Default 205k...... Blown Headgasket

Maybe the buyback is the way to go? Lol

Stopped blowing hot air long story short air was in the heater core, bled the system, will be fine until you drive it hard then air will bleed over to the cooling system again.

Well talked it over with the wife and she can't think of a car she'd rather have lol.

So first I'm going to try installing ARP head studs. A friend of mine who has built big power TDIs told me that he has had this same problem out of cars before when he turned the boost up, they would start getting bubbles in the cooling system and he studded it for more clamping force and it stopped. And if for some reason it doesn't work I haven't lost anything as they are reusable.

So yeah looks like we're fixing it. I'll update as to if this works or not or if the head needs to come off. If the head does need to come off I'll probably get a valve job, seals and everything to make sure it's good for a long time

It does have 205K on the odo... I'd take the buyback and consider an etron or a 328d. Best of luck.

Not interested in the etron and we both like the 335d but let's face it they are junk and I'd be working on it all the time and throwing a ton of money at it. She also likes the A6 TDI but I'm not buying that expensive of a car for her to put no less than 75 miles a day on.

I even tried telling her that we could probably find a TDI golf, Jetta or Passat after they get fixed and this blows over but according to her the Passat is big and boring and she doesn't care for the Golf or Jetta lol. I agree with her, the A3 is definitely the best looking out of the TDIs

I completely forgot about this thread. The car got a 30k mile used head and went back together with arp headstuds. I put on the cr170 and retuned to Malone stg 3. Awesome power and picked up a few more MPG too!

So it wasn't really the gasket but the head that was toasted? Did it over heat and warp? Haven't heard much of head issues on the VW platforms.

There was a lot going on actually and I'm convinced that all of it was due to a bad repair by the Audi dealer. I'll start with what I know about the car. We bought it with 70k miles. I found the original owner and called her, it had gone through a fuel pump failure and had the entire fuel system replaced under warranty and around 60k miles the serpentine belt came loose and got behind the harmonic balancer and the car jumped time and bent valves. Dealer fixed it and she drove it for a few more months and traded it in.


Soon after we got it I was going through and fixing fuel, coolant and boost leaks so I was always wondering what kind of "fresh out of NADC or equivalent student" had done the repair.
Around 90k miles it got deleted and Malone tuned and it gave me a trouble free 115k miles at 42mpg average.

I think around 150k miles I installed a magnetic drain plug and on the next oil change I pulled out this stuff:

I did some searching and asked a few gurus but nobody had a clue WTH it was from and pretty much everyone agreed that if the car wasnt making any funny noises and was running great and getting good MPG that this was junk left in the oil pan from the old repair and to not worry about it.


On to the head gasket repair many miles later. After removing the valve cover we found that 3 of the rockers lost the roller, causing the cam lobe to ride on the pin that holds the roller(finally got an answer to WTH those half shells and roller bearings were!) Cam lobe actually didn't have much wear surprisingly (probably goes to show how good these synthetic oils are these days!) Maybe having 3 exhaust valves not fully opening caused higher cylinder pressures and caused combustion to leak over into coolant passages? Or just a bad head install from a wanna be mechanic?
