2011 audi q5 2.0T FSI Timing Chain Check

I have finished a complete rebuild of my Q5 with the oil consumption issue. after the first start I got the p0016 error code. and the first thing to check is your actual timing marks. This is the long way of confirming upper timing marks. I removed the the spark plugs just to make rotation easier but I it took me a good 25 minutes of cranking to get the marks perfect.

I believe I have this problem too, I just finished doing a fresh rebuild exactly how you explained , and I'm getting timing codes , and runs supper rough . I check my timing marks and they sre spot on

[@psiturbo]

You have to make sure all the timing marks, balance and timing must be correct... It is two chains, if the balance shafts are off you will get rough engine. It may look ok on the top, but If it is off on the crank, you will get rough idle. It is tricky. There is a revised timing kit that has longer plastic molds to prevent the chain from slacking on the crank side. It has happened to me it moves by one chain link and have to redo it all over again. I have a GTi, same engine, did a full rebuild... Oversize pistons, overbore, eBay waffle piston rings (not the spring VW OEM, new balance shafts, cylinder head, intake manifold, water pump. If your car has a lot of miles, check if any of the codes relate to the dag flywheel, they start running rough when going bad. kzbin.info/www/bejne/Z5i7iqiIadp3aK8si=fevWDnAJd-afoMry A link for crank reference

@psiturbo so turns out my intake came witch has the vvt sprocket was bad , replaced it and all my problems and timing codes went away.

[@chrishaas6078]

Informative. Ty

[@Phytopathology]

Perfecto

[@EJR20]

When the tensioner is bad that it literally rocks/jumps, can that cause misfires? Or at least for the engine to think that it is misfiring because of course the timing will be off- which leads me to another question, can this result to p0016 code being thrown once then not anymore? For a better idea, the other morning, car cranked for like a quarter of a millisecond, basically just made a short noise like it’s cranking but car didn’t start, ran codes, threw p0016 (which means the correlation of blah blah blah is off), cleared it, right after- car started but with bad misfires. Hasn’t threw the code again, did a visual inspection and the tensioner is literally moving up and down about 2.5mm. Regardless I’m gonna replace the tensioner but the code it threw once has something to do with the timing chain, mechanics are telling me to take it Audi, nightmare.

[@danielsgarage3545]

Sounds like it may have jumped a tooth. My recommendation would be replace the tensioner, take the chain all the way off and realign all the definitely making sure the crank sprocket is aligned to the crankshaft. It is a very involved and technical job requiring some specialty tools without them you run the risk of catastrophic engine damage. Which is why most people just take it to the dealer. How ever if you mechanically inclined enough the tool kit can be bought for between $100 and $150.

[@nzerothreeone7728]

it doesn't matter if you just replace the tensioner because the tensioner will extend with the amount of slack the chain allows, meaning you will have a new tensioner but it'll be fully extended in -7 timing or more meaning the stretch is too much and you will need new chains. PERIOD. The only time the tensioner matters is if you have the out dated one that fails on itself. Replacing the one part isn't a cure all for chain stretch come on dude.

[@dointhangs23]

Daniel, I have the same 2011 Q5 2.0T. I need to replace the crankshaft sensor. Did you ever make the video of where this is located? I know this was a long time ago but any help would be great.

[@danielsgarage3545]

www.audiworld.com/forums/a6-c7-platform-discussion-194/crankshaft-position-sensor-location-2013-audi-a6-2942107/ This is the best I have found for location. I had to climb up on the engine and almost reach down blind. It is reachable without removing anything.

[@michaelogg1254]

It’s located slightly below the water pump

[@cedricenglish2677]

iam having the same code my engine had the same things done that you have done.what 2 sensors are you taling about replacing?did you ever find out what caused the problem?

[@danielsgarage3545]

i had to remove the entire timing chain again. the crank sprocket was not lined up properly to the crankshaft. I was 1 indent off, but when you torque the sprocket down it will appear to look right but it wont run right. pull all the chains off check the sprocket alignment and reassemble. don't remove the center bolt until all 3 chains are under tension. kzbin.info/www/bejne/eH7YgYuCpa5kZqc at 9 min 30 secs is when I discover the sprocket is off and line it up properly. I don't have a reassembly video. I was rushing and didn't get to film.

[@jacobperez4263]

What was the oil consumption issue and how did you solve it. I changed by oil separation manifold but it did not help I’m still having issues diagnosing it

[@danielsgarage3545]

Its the pistion rings. To completly solve it requires a rebuild of the bottom end. Pistions and rings. The oil ring get clogged up and allows oil to pass through and burn up. There are some options that have helped others called pistion soaking. Where you pour solvents down the pistion chamber but I have don't have any experience with this method.

[@Chamo-zh1co]

I understand this marks can be lined up only one time while you performing timing job but I don't think that you can make conclusion this way I believe that you would need to retime lower and upper chain to confirm since your lower chain isn't lining up right now it shows at 2:29?

[@danielsgarage3545]

you are correct, I discovered this in a film I never ended up making. both sensors tested good. it turned out the actual crank sprocket was 1 groove off time and I had to remove everything and start from step 1. After fixing the sprocket misalignment she fired up and ran smooth as butter.

[@Chamo-zh1co]

@@danielsgarage3545 Good work bro.

[@EJR20]

So you had to rotate the engine, so if the timing isn’t correct no matter how you rotate it can never align?

[@danielsgarage3545]

It depends. If everything is correctly timed it will eventually line up. However, if the crank sprocket is misaligned to the crank shaft, the timing marks will line up but still throw the code. Third option is if it is timed wrong you are right the will never line up.

[@stevestadnik9206]

It takes I believe 163 revolutions for it to all to align back up. I have done it and its boring, lol.

[@gerardomedel9619]

I have 2011 Audi A4 I got the same code p0016 can you tell me where is the location for the two sensors I like to start replacing these two sensors first before I go to the timing chain

[@danielsgarage3545]

Cam sensor is right on top middle of the valve cover. The crank sensor is on the bottom back of the engine block below and behind the water pump

[@itskarl79]

How much did this cost you to do? Did you replace the timing set at the same time?

[@danielsgarage3545]

the timing set had just been replaced by Audi just weeks before my full rebuild. parts prices can change a lot most of my purchases where from www.ecstuning.com, www.shopdap.com/, and my local VW dealer between the 3 and all the specialty tools required I was able to complete the full rebuild front brakes, brake lines plus everything else I cant remember for about $2500

[@marianeiva9932]

I am Brazilian and I have an Audi A4 2013 2.0 TFSI engine. It presents this error P0016, I delete it in OBD2 and the car normally goes both in the city and on the road. Can the problem be the car out of point? If it were the car, wouldn't it be weaker? If not, what else can it be?

[@danielsgarage3545]

If the timing chain or oil pump recently had work it could be out timing. If not I would start with the crank and cam sensors

[@marianeiva9932]

I already changed the CKP and CMP sensors. Could it be the variable control valve?

[@danielsgarage3545]

Could be. Wouldn't hurt to check. Since it's not the sensors I would check the timing chain itself for stretching. If it has stretched to much it will throw this code. Have you checked the timing marks to see if they line up to the dots? You may have jumped 1 tooth if its stretched. When mine was 1 tooth off it would have a hard time starting and would only rev to 4500 ish

[@marianeiva9932]

I didn't check anything on the chain. But the car has no difficulty in starting and walking, I only see the error because I use obd2. The car gives no signal. But for security I will check the current point. Thank you!

[@Aaroncreate24]

I replaced my timing chain and tensioner everything was lined up with the timing marks and torque to spect. I gave it a couple turns and the timing chain is not lining up with the with the bottom marks only the two on top line up. Should I redo the timing?

[@danielsgarage3545]

It can take up to 50 rotations to line up if everything is correct. My bottom sprocket was misaligned by 2 v marks but when torqued it sat flush. If the don't line up every I would redo your timing and double and triple check the Main sprocket on the crankshaft

[@Aaroncreate24]

Daniel Haak thank you for the information I will redo it because i turned it more then 50 times and didn’t get them to line up

[@Aaroncreate24]

Daniel Haak ok my timing marks are lining up after rotation but I hear a little popping sound as I’m rotating. Is that normal?

[@danielsgarage3545]

@@Aaroncreate24 like a compression pop? Should sound like a smooth chain gliding through oil.

I have the same problem with my audi a4 with the P0016 codes. If the engine is still working , does it means my chain arr not broken yet?

[@danielsgarage3545]

Not badly broken but will need work asap.

[@Jayosf415]

What was the fix? Thx

[@topnews1007]

How about the timing tensioner

[@danielsgarage3545]

Easiest way is with vcds or obd11 software. You can read one of the adjustment numbers should be -5 or smaller and you are good. Unfortunately I dont have a video on that to show you. Otherwise there is a small inspection hole on the front lower chain cover that opens and you can visually see how far the tensioner is protruding out. I am not sure on the number of rings showing to equal bad but I believe it to be 7.

[@nzerothreeone7728]

if you show -7 or more during normal idle you have too much stretch, Daniel is guessing

[@ny.3nthusias651]

Does this marks apply to a 2010 a5 2.0t?

[@danielsgarage3545]

As long as it's a chain drive then yes they are the same.

[@danielsgarage3545]

I believe Audi converted to chain drive in 09. The upper chain cover is very easy to take on and off to verify.

[@ny.3nthusias651]

Ok thank you !

I have a 2008 audi a4 2.0 and the code P0016 came up now my car cranks but wont turnover

[@danielsgarage3545]

Sounds like timing has jumped. Any recent work done? I would start with checking the timing marks to see if the are on point. If that checks out. Look for fuel and spark. Then compression test. If it did jump timing. Re time then see if it runs. If it runs. Replace the chain and tensioner and your good to go. If it does not fire after retaining. Do a compression test before replacing parts to ensure you didn't bend any valves.

[@ctzduce2k]

your timing marks are off.... if you look at 2:27 and pause it you can see the mark on the outer gear.. the triangle and your link is pointing at the mark for the balance shaft chains looks about 4 teeth off

[@danielsgarage3545]

What it turned out to be was the actual crank sprocket was off from the crankshaft. If I rotated the entire assembly enogh all the markings would eventually line up, but the internals where still off Making everything off timing by 2 or 3 teeth according to the sensors.

@@Japplesnap Great Question. I thought the same thing before it happened to me. The pattern they used is sutle enough that if you misalign it and torque it down there will be no gap or indication that it is not on correct until you try and start it.
