Hi,

Today i got these codes on my 2011 Q5:

The ones i'm most concerned about are these 2 on Address 01: Engine:

Any ideas?

Thanks in advance!

Bob Petruska

Is the engine running? If so, does it sound ok and have the same power as usual?

Is this a 2.0T and has the timing chain tensioner ever been replaced?

I wrote a lengthy reply this morning, with all the details of what happened when i got the issue, but somehow it didn't go through; it said something about a moderator having to review my post (?)... weird.

Well, take two: to summarize:

- Starter runs, but engine doesn't start. it never went to "limp mode" or anything.

- It simply had a brief "hiccup" on the power and then lost throttle and power steering, all after maybe 2 minutes of start, and without me doing any sudden acceleration or anything; in fact, i was (thankfully) going at a very low speed when this happened. At that time i simply pulled over, walked back home, grabbed my Audi TT, and towed the Q5 back home (less than 2 blocks away).

- Before the failure, i had no MIL or unusual noises during start. Only thing i noticed was that the sound system wasn't properly working; i could see me media screen on the MMI, but there was no sound; as i was fiddling w/ the sound, that's when i got the failure. Since i have a couple of electrical fault codes, could it be the case that an electrical failure triggered this whole thing?

- It is a 2011 2.0T Premium Plus Q5. Bought it on October 2015, with a little bit over 100k miles at that moment, so i'm not sure if timing belt (chain) and tensioner was previously replaced.

- It has 127k miles now. This have been my first "major" issue w/ this vehicle.

Hope this helps clear the picture a bit.

Thanks in advance!

Geez I hope it's not a timing chain issue.Audi should be ashamed of how they've handled this issue with the 2.0L T .Guess they spent all the spare cash on Dieselgate and 2.0L T oil consumption issue.

Bob Petruska

Yes, the electrical issues seem odd if the timing belt tensioner failed.
Hopefully it is just some fuse/relay etc. causing the non start issues.

But you do realize that you most likely have a version of the timing belt tensioner that is known to go bad and damage the engine (valves hit the pistons) cost to repair is about $7K at a dealer.
If you plan on keeping the Q5 much longer you may want to invest in replacing the timing chain, guides, and tensioner.

A quick check to see if the tensioner failed,and if the valves are bent, is to perform a simple engine compression check.

Also if the engine spins more freely trying to start than what you remember before the problem, then it is probably a good idea to check the compression.

Well Bob, thanks for the heads-up... i really hope it doesn't come to that

I was planning on replacing the timing chain, guides, and tensioner, after a conversation i recently had with a close friend who is an experienced mechanic, and he also mentioned that a compression test will shed light as to how bad the issue really is; i have an alternative to bringing the SUV to the stealer... so i'll get the comp test done, and if it goes well, i'll move forward with the timing chain replacement.

Wish me luck guys... i certainly need it!

This got me in a particularly vulnerable moment, so i hope i'll somehow get to dodge this bullet...

Again, thanks!

Bob Petruska

Hopefully it is just an electrical issue.

If the tensioner failed and you only jumper a tooth or so you may have not damaged the valves, keeping the expense down to a tensioner, chain, etc.. If you keep trying to turn over the engine you could cause the chain to jump more teeth and then damage the valves which will run you a few $K more.

Many owners have had the tensioner fail and valves damage at just trying to start the car.

MurrayA4

virtuallyreal I understand the " getting nailed at a vulnerable moment thing) ! Hope the compression check comes back good.Bonne chance.

Thanks Murray; i really appreciate the kind wishes

Again, thanks to everyone, i'll keep y'all posted.
