THE Timing Chain Tensioner Failure Thread

[IbisB8.5]

I bought the car used at 76k and now I have 114k miles. I’m not quite sure what cam phase adjustment is, I’ll look into that.

Ok so I have a little bit more time, I’m getting over active duty this week so I have some money to buy the parts, I’m be doing this myself. Just wanted to make sure I want about to blow up now

If you could access vagcom, obdeleven, carista, etc you can read your cam phase and it would be helpful for us to see

Is it easy to check the tensioner condition? Do you need to remove the bumper in order to get to that hole? I briefly tried to locate that hole on my car. But I couldn't find it.

Go up from below. Pull the belly pan and the plug is in that lower, metal cover. Once you pry out the plug, you'll need something like a dental mirror to see in there. I think some guys have just snaked their phone up between the radiator and motor and snapped a pic. It's not that hard.

Thanks IbisB8.5. So this picture below equates to -5.84° phase adjustment. I think we're coming to the conclusion that anything around -6.00° or higher is a stretched chain at risk?

[IbisB8.5]

Ok thanks for the info! So I should change it as soon as I can I guess, but I have to drive from Jacksonville, NC to CT....I should be good right?

[IbisB8.5]

Hey guys, so this might be a dumb question but from looking at ECS’s website what timing chain kit would I get for MY2013?

Thanks in advance and for your guys input

Do anyone know that you can check your timing chain condition through OBD2/VCDS port? Someone who is an Audi master tech plugged in and looked for me. Mine shows zero. He told me the timing chaining is stretched if the number is -2, -3 and really needs to be replaced if it shows -4 or -5.

I have a 2010 A4.

Yes. Kind of. Read through this thread:

https://www.audizine.com/forum/showt...ser-adaptation


On a 2010 you should go ahead and get the tensioner, chain, and guides replaced ASAP. It doesn't matter how much stretch you have because the tensioner can snap at any time and cause catastrophic damage.

The screen shot in the thread linked is not the one I have seen when the guy show me on his laptop. The number isn't representing in degree. But thanks for the link.
I think it will be a good reason for me to get a S4 if my tensioner snaps.

[medvedko]

OK....... I am getting ready to tackle this job so just need a parts update.
Cut to the chase, I am getting all new part numbers for the Primary and secondary chains for my 2010 A4 Avant-
Primary Old -06k109158AD New -06k109158BE
Secondary Old -06k109158A New -06k109158BS

Secondary tensioner has a new # -06H109467AR old # -06H109467A

Anybody want to clarify this and have one to compare to the old chains, seems these #'s have been updated on other parts sites as well?

The Cambridge I have ends in "J" new one now ends in "K"... old on was like $100, new one is over $200..... anyone know if its a complete redesign? I had mine changed
when it when in for stage 2, has about 20k on it. Should I sit on it for another 45K and check if the screen poped out or just replace it now?
The balance shafts, any maintenance for these or is this something to do when the head is off the car? My engine is fine with 73k on the clock, I just want to get the timing chains and tensioners
updated.
Any help with this would be great as I am ready to order these parts.

[Spawne32]

06K109158BE for the upper, looks like it was revised AGAIN (primary chain) and 06K109158BS for the balance shaft chain, also looks like it was revised yet AGAIN. 06K109467K for the primary tensioner, balance shaft tensioner which is not needed to be replaced is 06H109467AR. You shouldnt need to replace the cam bridge at all. Pull the remaining parts of the bridge particulate screen out of the cam bridge itself and leave it empty. Long as the check ball doesnt fall out its fine. That's what I did on mine.

Spawne32, thanks for clarifying! I'll get these parts ordered up this week and get the job done!
BTW, I enjoy your posts as well as all of those who have contributed their knowledge to this timing chain issue.

Google says this was posted 7 days ago. Is this a new lawsuit? Another one? I hope so!

[medvedko]

Quick question, , in regards to the chain on the balance shafts, do you need to drop the motor? How much extra time to get that chain off? Just doing some research and haven't seen one come off in any of the DIY videos. Thanks.

Anyone know if it matters that my 2013 B8.5 (July 2012 build date) is a flex fuel (E85) engine model? I am still gonna take a peak through the little cover window, but right now I currently have 60k miles. Rather just get a job like this over if needed before it's too late.

Dunno if you bought your parts yet, but I'm getting ready to do this job as well on my kid's 2012 w/87k miles.

I bought both chains (latest versions, BE, BS), both tensioners (K, AR), cam bridge (K), all six guides, top cover gasket, intake cam seal and a new bolt ... $651.11 from audionlineparts.com
I asked ECS and they couldn't even come close on pricing. I wanted to stay with "Genuine Audi" parts in the event one of these class action suits ever pans out. I ordered a new lower cover (Elring) from China via eBay, about $70.

Hi,
I have a 2011 A4 Premium + with 110k miles. Pulled my service history through the dealer:

This is what my dealer is saying:
" it doesn’t look like the timing belt was performed. The timing belt package runs about $1800-2000 for the repair."

I got the car used at 94k, was wondering since I plan to keep it for 1-2 more years whether i should get it done?

Yes. And when you sell it you can point out you had it done and ask for a premium for it, recouping some cost. I would have it done at a german car specialist indie for cheaper than dealer.

Hello Guys,

Do I need to replace my secondary chain or only the main one fails?
Mine was replaced at 106,000km 3 years ago. Now I'm at 150,000km
Looking at the notes I see this is what it was replaced by
Chain# 06K109158AD
Tensioner# 06K109467K

I can't recall seeing any reports of wear issues with the lower chain, although some have done it "while in there". The timing chain is quite long and has lot's of link pins which can result in enough cumulative wear over time to cause problems. It would seem that stretch in the shorter lower chain would be much less over time and less likely to cause major problems. Just my theory though.

Chiming in with positive notes.

2012 Audi A4 Avant 2.0T, 146,706 miles
Original engine, timing chain and tensioner

Build date on VIN 12/11
Build date on Car Data PR code dump 02/01/2012

This is my 12th Audi quattro and a 2012. Total keeper — Prestige, S-Line, sport package, factory Audi 19" rotor rims, Glacier White Metallic.

Just bought this, only put on 700 miles so far. Immediately scheduled engine timing chain, tensioner service. No service history records from Audi having any of the timing chain or tensioner replaced, only water pump replaced at 85k miles. Engine runs great, no bad sounds, pulls strong.

Measured last week through VCDS
Camshaft adaptation intake bank 1: phase -7.91



Good thing I scheduled this.

Talking with tech this morning, tensioner was at limit — totally maxed out! He noted we were SUPER lucky. Chain was stretched, guides didn't appear to be too worn at all. Balance shaft chains, tensioners looked fine. Every timing chain tensioner job he does, replaces the camshaft bridge. He's never seen a bridge with the screen intact. Mine was one of these, but fortunately, screen parts were there in the journal and recovered. Used all factory Genuine Audi parts, including a new serpentine belt.

Just picked it up this morning, all buttoned up, runs great, smoother and tight. Love this Audi B8 A4 Avant, everything about it, styling, ride — Audi does the best job of designing a complete package. While it's no where near as fast as my 2002 S6 Avant, it is a newer, more refined Audi than than the S6 (which by the way, is for sale). While the front was off, I had them drop in some new DS3 Phillips HID White Vision 5000k HID bulbs, figured it was a good time to do that! (Note: three guides were replaced, only recovered two from the bin to snap off the photos).

This is really good info. This helps confirm what we've been seeing. If the phase adaptation is up around -7.00° you might want to locate your panic button.

On top of it all, you had the old style tensioner with the metal band that used to slip out of place no matter what the chain stretch.

[BeerBrent]

^ It's a little reassuring that you got 146,000 miles on it before replacing. I want to get mine done, but dont have the $$ right now. I'm at 70,000 miles.

What is the phase with the new chain?

What is the phase with the new chain?

Good question. I'll get a chance to check this after a good long drive from Vermont to Florida and back =).

I'll have to plug in at the shop, on a weekend. Currently I have the older KII+ VCDS cable (for my C5 S6) and need to upgrade to the latest cable.

Just remember, take the reading with the engine warm and it's been running for a minute or two. Otherwise you'll get a 0.00° Reading which is false. Most of us have been slightly + after a new chain.

[studioRS]

Good tip, thank you. Yes, the only time I've taken the reading (photo and note above) was at operating temp and an at idle.

[choppstixxx]

Took a peak at my 2013 (July 2012 build date) view port, (thank god) I have the revised tensioner. I’m at 62k miles and looks like I’m down to the 5/6th tooth, this seems about half way down IIRC?
