Results of measuring timing chain stretch via cam phaser adaptation.

You probably could but it is SO much easier to take the nose off. The missing bolt is probably broken off due to not being replaced the first time. The balancer is mega critical on it's position at install, that deserves a "head on look" before You torque down the NEW damper bolt- with a ton of torque. I'm new here too, so this is just MHO. Good Luck!

I would try and thread a m6x16? Bolt into those holes- standing by my earlier guess of them being broken.

This really isn't the place to garner many comments/opinions for the timing cover leak issue you're having. Good Luck!

Thanks, appreciate it. You're probably right about the appropriate thread. I was initially just going to update an earlier post regarding my pre- & post-chain replacement numbers, then piggybacked this additional problem without really thinking about it since I had previously mentioned the issues this shop seemed to have getting the job done in the first place.

I've thought about just trying to squeeze the missing bolts in, which seems like it'll be a bit of a PITA in and of itself, plus the general consensus from other sources is the cover should be replaced and resealed with all of the bolts and tightened in the proper sequence. The missing bolts aren't broken off in the block at any rate. I'm in a back and forth with the shop owner as it stands, having to email him pictures of the empty threaded holes in the block because he thinks I'm just confused and that I have an older 8-bolt configuration that now uses the same 15-hole (plus 2 more for the locator studs/dowels) cover.

Damn, that's just an astounding lack of mechanical acumen. You don't need to be a master level tech to figure out if you take out 15 bolts, you should probably put back 15 bolts. I'm pretty sure someone who doesn't even know what a timing cover is could figure that out.

If they don't do right by you, definitely let everyone know what shop that is so they can avoid it. Hell, even if they, you should let people know because that sounds like a shop people should avoid altogether.

The owner's final position on the matter is that he spoke at length with the technician who performed the service, and he insists there weren't 15 bolts holding the timing chain cover on when I brought the car in. I've spent a ton of time underneath the vehicle. All 15 bolts were definitely 100% there prior to bringing the car in.

his job is to fix it. why wouldn't he put them in even if they weren't there ?

That's a great question, and one that the owner didn't feel inclined to answer.

Super stoked today. A few years back my value was -2.66 at 75K miles (2013 B8.5). I had the shop check it today (100K miles) and it's -2.81. That's basically just a rounding error. So I may never have to change my timing set, planning to run this car until it at least 150K, which could take me about more 10 years to hit.

But I should probably do a carbon clean sometime soon, never been done.

2014 Allroad 123k miles, just finished carbon cleaning my intake valves and decided to check my timing chain tensioner, this where it’s at, checked my cam phase couple thousand miles ago and it was around -4.87 or so, looking at the tensioner I think I need to purchase all the parts and get the job done.
Car is not consuming any oil, maybe due to the fact that I’ve done piston soak for the third time since purchasing the car.

Nice. With your current phase value and tensioner extension you can comfortably make it another 10k miles but of course doesn’t hurt to do it sooner than later

Hi all,

Apologies if I happen to not be in the correct model forum, but I did want to post and gain some knowledge on my current situation.

I have a 2014 Audi Q5, 2.0 TFSI gas engine - build date of Jan 9, 2014. I just passed 150,000 trouble free km with it. (I bought at 84k), and I'm in Canada.

When I bought the vehicle, I was aware of the timing chain/tensioner issues, and there was a site (which I cannot seem to find now) that allowed me to punch in the VIN to see if it was eligible for warranty or for taking part in the class action lawsuit here in Canada. My VIN said I was unaffected.

However, I also just got the dreaded P053F and P0088 codes, which led me here, among other sites.

I used VCDS ver 16.8 and found that my camshaft adaptation intake bank 1, phase position reading after a 30km drive was -10.7!!!

I plan on parking the vehicle tonight, and going under to view the tensioner through the lower timing cover inspection port to see if that value is really accurate, as I have read through this thread and have a hard time believing that is could be the actual value without seeing any potential issues.

Other than the codes, which do come back after clearing, I have had no noticeable loss of power, no chain noise, nothing at all that would indicate a problem - the only thing that clued me into this was googling these codes and falling into the rabbit hole of some 2014 models having updated tensioners, but original style chains. Yikes!

Anyway, I'll post that pic of the tensioner view window tomorrow to confirm my suspicions, but has any thoughts on if Audi Canada will potentially cover this? I do have a letter into customer care.

Thanks for all the previous information, and for your help.

90-120k miles is within the normal range for timing replacement, whereas 10.7 is quite high it’s not unheard of with the new(er) tensioner to get to this point without a catastrophic failure.

As for your fuel codes low/high, they might go away after the timing service as the hpfp runs off the cam lobes and it might be a bit out of sync given your phase number.

228k miles -4.5 Ill be considering a timing chain replacement in the spring. I looked back and seemed to miss one data point 223k miles -4.3.

[Theiceman]

Audi doesn't cover 2014 . you are well.past any claim date on the law suit also. by years.
just plan on fixing it and move on. 2014 does not have updated chain, it will need replacing along with guides and pins. I was 8.8 at 220k km. your does seem early

Alright, try again…

After I had changed my oil and took drive, I took a look at the measurements for mine since I’m at 179K miles already. I got a reading of -3.03

Tensioner was replaced back in 2019 at approx 122,208 miles

I think having almost 57K miles so far is pretty good, not great—just good. I think I’ll retire the Avant from daily driver duties within a couple years

you will get to 100k...then it wil be time again
