So perhaps it's worth still ordering these duplicates, but if you're replacing the whole Camshaft Bracket (the Camshaft 'Bridge'; 06H103144K), it already comes with a new O-ring. You can actually check it out
here on ECS Tuning.
Also, how does the pricing compare between ECS Tuning and the Audi site you're using? I, perhaps somewhat naively, assumed that ECS Tuning would be the cheapest source. The Camshaft Bracket on there is $243.18, for example. How much is it on your site?
As an aside, I didn't replace the camshaft bridge, as mine looked great. And I also didn't think to order the O-ring, but fortunately, that one was in perfect order, so I left it alone. My screen was also fine, and I didn't want to muck with it (and I change my oil super often) so I also left it.
And does your car need 15 of the N91096702 (lower timing chain cover bolts)? Some cars require fewer, I believe 8. I'm mentioning it mainly so that you don't order 8 (off of some documentation for such a car), and end up needing 15. (My MY09 required 15).
To your questions:
Is it recommended to remove the oil screen from the cam bridge?
- I've seen recommendation of this, but I have no idea how to do it, and mine looked -perfect- so I left it.
How likely is it that the check valve in the bridge has broken?*
- No idea. I did see them in there though. They looked happy.
Are there any tips for removing the lower cover without bending it? Use a heat gun and razor blade to break the sealant?
- Not that I've seen. And there are guys who've done this, and bent them, who seem like mechanic super-dudes.
- I tried for probably 15 minutes to see if I could get it to budge, without bending it.
- In those 15 minutes I came to the conclusion that it's a trade: You can probably remove it without bending it, but you'll instead mar your block. So in other words, I don't think it's practical to not bend it.
Some additional questions/notes:
1. What is REINZOSIL for?
(I'm not familiar with it). If it's for the lower timing cover, I used the official VAG stuff,
here, FWIW. (I may have overpaid for the same stuff... oh well.)
2. What tools/supplies do you have? Preemptively, here are the tools that I bought for the job:
- Timing Service Tool Set (Schwaben 020946SCH01A),
here
- 9 Piece Scraper, Hook and Pick (Schwaben 008504SCH01A),
here
- Locking Tool set; covering the old timing chain tensioner, the accessory belt tensioner (at least for MY09), and a 3rd tool I didn't use,
here
- Do you have replacement coolant already and a way to refill and purge? I didn't so I actually got this kit (
here), which I highly recommend. If you already have the coolant, you can get the air purge tool separately,
here.
- Torque Wrenches. I have small, medium, and large, and needed all of them: torque specs range from 1.5Nm to 150Nm + 90 degrees (crank pulley) on this project.
- Wobble Extenders. I need one to be able to torque the impact absorber back on driver side, lower left bolt. I have these,
here
- 27mm Socket. This is needed to get the balance shaft tensioner on/off. (This is the one tool I had to run to a local parts store to buy... my set only went to 24mm)
- High temperature zip ties. I use these guys,
here. You'll have to cut several factory zip ties in the process. You want to make sure you have ones that can handle the heat in there; standard ones cannot. Those are rated to 266F, spec sheet
here.
- Torx and Triple square sets. Have some I recommend if needed.
3. I didn't replace the cam bridge bolts. They're not torque to yield bolts (they're torqued super-low; 9Nm), Audi doesn't specify replacing them (they also don't recommend against it), and they looked fine, so I kept them.
4.
ERROR: If you're planning on replacing the 6x cam bridge bolts (the bolts that hold the cam bracket to the head), you have the wrong bolts. The bolt (N10572403) you have listed with quantity 7, is actually only quantity 1, and is a triple-square, not Torx, and is used on the exhaust camshaft only. See below:
If you do want to replace the other 6 Torx bolts, they're something different, but since I didn't replace them, I'm not sure of the part number on those. Again, Audi doesn't specify replacing them (as they're torqued super-low (9Nm) and very unlikely to need replacement). And factoid, the exhaust cam bolt is the same one that's on the high pressure fuel pump (at least on MY09). I did of course replace the exhaust cam bolt, as it's recommended (and it -is- TTY; 20Nm + 90-deg turn).
5. Do you already have a dipstick? If not, I'd say install one as you'll need to be correct on the oil on refill, without the luxury of starting the car. I got this one,
here
6. How old is your accessory belt? I installed a new one because it was easy at the time, and I don't have service history going back 60k miles (I didn't own the car then), so figured I might as well. I used this one,
here (fits up to MY2012)
That's all I have.
So I'll leave you with these guys,
here, which I love for taking off and putting on the wheels.
Cheers!
