What happens if it completely fails? My car is a CPO car so I am not worried about having to pay for it but if it will cause a lot of damage and I have to be without my car for an extended amount of time I would like to avoid that.

You could wear a cam lobe down and destroy the cam. It can gradually run like crap or just have a major cam failure.

I'm sure a competant dealer can have your car back in a day or 2. If you are CPO like me no worries but if you want to replace ahead of time it's a small job.

This is exactly why all my cars are now CPO. Won't buy any other way.

I just had to have the intake cam replaced, I'm guessing because of the cam follower failure. I have a 2007 A4 S-Line 6spd with 48,255 miles, when I purchased it from the VW dealership it had some stuttering, serious performance issues and sometimes it would just refuse to accelerate all together. After taking it to two Audi dealerships the second one finally figured out the problem. The first dealership found a faulty low fuel pressure sensor, and a shorting ECM relay and figured they had fixed the problem. Guess they didn't drive it, it was still hesitating and refusing to accelerate after I got it back.

The second dealership actually got their hands dirty. They said the intake cam had premature wear on it, and was being replaced under warranty. I hope that they replace the cam follower, and you bet i'm going to ask before I pick it up today or tomorrow. My question is: Does the worn cam damage the engine at all? Driving Honda my entire life I have come to know that damage to the cam usually points to oil starvation, but I dont know much about these 2.0t engines.

As I understand it, the cam lobe and fuel pump will only get damaged if the cam follower wears completely through. At that point, the cam lobe and fuel pump come in direct contact with eachother, which is definitely not good. The cam follower acts as a buffer between the two.

If you swap out the cam follower before it wears through, you'll be fine. I just did it a few weeks ago and it was an easy job. Well worth the $50.

I have a 06 B7 with 128k and a Stage 2 Revo chip and have never had a problem with the cam follower. I drive about 500-1200 miles a week, 90% highway so I don't really beat on it. I should definitely probably check this out huh? Kris what do you think?

I have a Audi 2006 with about 115K km's.

With all this talk about the cam failure issue, I asked the dealer about this problem and they responded as if its a non- issue, and something that I should not worry about.

My warranty runs out at 119K. I decided to check the cam follower just to be on the safe side and I guess by the picture you can see that this one has bitten the dust.

The cam follower has a hole in it, and the cam shaft although soft to the touch, when you run your nail across it, you can feel the scoring on the cam lobe.

Need new cam, new pump with cam follower, and also check the engine for any metal left behind from the follower plus a complete oil change. I am very very lucky, that I had this checked or else it would have been a very costly repair. The dealer is going to replace everything on warranty.

FYI TSB: 150605

AUDI TSB # 15 06 05 2013147/7 MIL on

This (TSB) Technical Service Bulletin, describes the MIL on (Check engine light on) the reason being excessive wear on the intake camshaft lobe that drive the high pressure fuel pump, limiting maximum pump piston lift, causing fuel rail pressure fluctuations. the wear on the cam lobe also leads to wear in the base of the high pressure fuel pump cam lobe.

This condition causes the following DTC Codes to be stored in the ECM Data Memory
P2293 (Fuel Pressure Regulator 2 Performance) at times in combination with
P0087 (Rail fuel pressure too low)
P1093 Fuel trim 2 bank 1 malfunction)
PRODUCTION SOLUTION

Increased Surfaced Hardeneding of the camshaft lobe for the high pressure fuel pump Improved intake camshafts with part# 06F109101B

Mine went at 86,000 miles on my 2006 2.0T. Took the cam with it. I complained to the dealer several time about low power on hard acceleration, and had a few CEL show up until the correct CEL code popped a "Low Fuel Pressure". Anyway, the car was still under the CPO warranty, so Audi paid.

is this problem only associated with the 2.0T engine or does it happen to the V6 too? does the turbo cause the oil to coke? would the coke particles accelerate the wear? or would the demanding turbo engine deminish the oil film strength quicker than the naturally aspirated engine? or both? i've always advocated more frequent oil changes (5000 mile/8000 km) for turbo engines.

Thanks for all the info guys.

I use full synthetic oil and always change it at 6000km, and the cam follower still failed.
