Hey guys I know this subject has been beaten so many times and I read about 20-30 threads to see if anyone was in the same situation but couldn't really come up with anything good.

So got this 2006 B7 about a month ago with 124xxx on the clock and only drove it about 700 in about 10 days then put in my garage and started my usual maintenance that I do on any used car I get to make sure I am driving a reliable car that won't disappoint me. Car drove fine but I felt a little bit of power loss especially at 0-10mph. The engine has a very slight roughness at idle but it's really hard for me to tell what rough idle really is on a a 2.0t. Car had no CEL or any other lights. So I started some maintenance, Checked filter, fluids....etc. Then decided to put a straight pipe in and while in the process I found that my flex pipe was messed up so I ordered a full exhaust and waited for it. I installed the exhaust this weekend and all is good. At this point I was still thinking of what I could check on this car that usually causes problems and needs maintenance...you guessed it. I pulled my HPFP and found the dreaded busted cam follower in pretty bad shape. Here is the picture:

As you can see the cam follower needs to e replaced. The cam lobe feels smooth to the touch but can't really tell how bad it is damaged. Looking at the follower I think the cam lobe isn't too healthy either and will at least cause the new follower to wear out prematurely. The HPFP doesn't look like it's damaged as far as I can tell.

No CEL was ever on and really no major issues with the car so far. However I pulled fault codes and came up with the following:

008801 - Boost Pressure Control Valve (N249): Mechanical Malfunction
P2261 - 008 - Implausible Signal - Intermittent


000769 - Cylinder 1: Misfire Detected
P0301 - 008 - Implausible Signal - Intermittent


004243 - Bank 1; Fuel Measuring System 2: Malfunction
P1093 - 008 - Implausible Signal - Intermittent

I know that the extended warranty for the cam follower / cam shaft / HPFP is until 120,000 Miles/Ten years (useless to most ppl). Clearly the previous owner didn't take this to a dealer to inspect the cam follower and the dealer probably wouldn't have done anything about it if there was no CEL. Obviously 124,000>120,000 however I feel that just because previous owner didn't know about he problem/ didn't take care of it at the right time, Audi should still fix the problems caused but the car they made that destroys itself. I have no problem just replacing the cam follower but i will not go through the trouble or expense of changing the cam shaft. I don't know if i have the A or B version of the shaft. I am not sure if you can replace the lobe part only on the B version of the shaft either.

I really need to get my car back on the road and don't want to waste any more time on this. I need to know if i should put the car back together and drive it to the dealer and hope that I can convince them to cover this under warranty even though I am over the miles. Or if should just replace the follower and hope that it doesn't wear out too fast and just keep checking on it like every 6 months. After all, we all know this wear on the cam follower that I have didn't happen in the past 4,000 miles. What do you guys think?

Stick a new follower in and drive to the dealer.

No, don't do that! THey will NOT fix it then. Put the broken one and tell them you think its broken and for them to check it. Offer to pay the $100 diagnostic if they don't want at first. That fee will be waived when the find the problem. Next problem is your slightly over the warranty but any decent dealer should still honr it.

That's what I thought would be best to do. I just hope they don't say anything about the test pipe. No other mods of chip. i cleared the codes so i am going to put it back in and drive it a little to make sure codes are back.

You're past 120k, running that cam follower is not doing anyone good. Take the cam follower to audi and be honest tell them you just bought it that the can follower is reall messed up and it couldn't have happened within the past 4k miles
