Survey; When did your cam adjuster/tensioner(s) fail?

[lswing]

Just wanting to log this as it seems to be up there in the costly repair category, and a buyer should be aware this will happen around/after 100k.

Rough idle and flashing CEL on startup; upon scan the driver engine bank 5, 6, 7, 8 was mis-firing. Upon scanning measuring blocks (70 & 72?), the cam adjuster on driver side was reading -7 (not working), while the other reading 16 (working).

So mine went, plastic roller for chain completely shattered on drivers side, at 98k. So far no other damage that we know of, and will also be replacing passenger side (which is a pain).

Here's my updated list, will keep adding to it. Who else has changed this lovely $650-850 part, times two?

Hey, if every part on this car lasted 100k miles I'd be happy!

Cam adjuster went out at 95K.

lswing
Drivers side cam adjuster disintegrated at 98k, passenger worn but replaced also.

fbatwork

Well I'm at 120k and they're still holding up. Fingers crossed for another long while!

Hope so. Figure oil quality and driving temp play into the degradation of the plastic rollers. I'd replace next time you need to open things up. As far as I know my passenger side one is fine. I'll be cleaning it up once removed, and looking closely for hairline fractures starting, will post high res photos.

How many of you park then open your hood?

At home I pull in the climate controlled garage....open the hood.....turn on the box fan that blows across the engine.

Heat soak is a killer

I'm anal like Dave. Everytime I get home the hood gets opened. All vehicles including making my girlfriend open hers too. Did I spell this right? Was my punctuation correct. Should this be caps....bold..... No issues here.

[DHall1]

At work...everyone asks whats wrong with my Audi. The hood is always up

:-)

[lswing]

Always have when driven hard/hot, maybe the Texas heat finished it off this summer. Got to figure the aging plastic plays a part...

I replaced mine at 65K - they was probably 25% left. I was going through everything and did them so that they did not fail later... They are close to a Porsche with the exception of the shoe size, which is unfortunate because the Porsche ones are half the price...

[Bigglezworth]

Haven't changed this part out yet on any of the trio here. 121K, 125K, 245K on each respectively. If any one of them is 'due' it's the 245K. Am goiing to be doing an EGT sensor and a couple of other odds and sods on in over the next week so I'll check things out on the two heads then.

[lswing]

Very interesting, good to hear some numbers. B, you mean 245km...lucky...I'll place weight on temps, I know my car has run hot with the tune. Cooking plastic....

[Bigglezworth]

242000 miles. 390000kms

147k miles - still the original ones, however i did change this weekend one solenoid on the driver's side . I used to leave the hood opened but it slowly killed my battery because of the alarm plus everybody wondering wtf is wrong with my car everyday .

Bigglezworth - EGT can be replaced in situ by only removing the airbox, my mechanic did it so this weekend.

Thanks Maria! Now you're going to have to keep it for another 100k miles

Only one? If so drivers side?

They said my passenger one was ok, but we replaced since it was opened up. Will be interesting to inspect the part, plastic guides were worn but ok they said.

Wow. Nice!

This is what my invoice says:

Labor was 3527.17 and parts were 157.28.

It wouldn't surprise me to be honest. It did have extended warranty.
