Check Timing Chain Stretch on 2.0T TSI VW/Audi Engines - OBDeleven Scanner + Inspection Plug view

[@user-sg6xv2kb8s]

Nice job. Spraying the CPS and timing cover plug with brake cleaner or similar before removal can help avoid any debris from entering the engine.

[@gee3883]

loads of oil under the turbo is that coming from the cam cover, cheers.

[@BrenoAutoGarage]

I’m not sure, but I’ll find out what all needs fixed when I replace the chain later this spring. Thanks for the comment.

[@emirbergsland6704]

Mine is at -1.38 intake and 0.75 exhaust is that bad or is it good? I measured it on OBDeleven with the live data option for camshaft intake and exhaust deviation

[@bhpbones]

That’s ok, just means it’s moderate stretched, be ok a bit yet

[@sebastianmedina1234]

He said the specifications from VW want it to be plus or minus 5 degrees from zero. So you are very much safe for now. If I were you I would keep my eye / ear on it. If you hear the rattle become worse or more prominent check it again to see if things are changing. Or just check periodically from here on out until it creeps closer to that 5 degrees

Hello, Sir. I have a question. The timing chain in my VW Fox 2006 car has stretched. Do you think it's okay to drive 10 miles a day, but only for short distances? Thank you very much in advance for your answer.

[@BrenoAutoGarage]

I am not familiar with the Fox, so first research if your engine is interference or non-interference. Non-interference no big deal, even if the chain slips or breaks engine should be ok. If it’s interference then it depends on how stretched it is, and how much you want to gamble. If VW spec is +/-5° then I would not to push the engine hard above that. But some people get to 8-9° stretch without issue so you never know...

Any basic settings/adaptations that need to be reset via OBDeleven after replacing the timing chain? I have the older Android-based device and the newer NextGen on iOS. I was at -8.71 for “Camshaft adaptation intake bank 1, phase position” with a fully extended tensioner when I got the chain replaced. Post-replacement the OBDeleven Android device is reading -.92 for phase position, but the NextGen is giving a strange phase position value of 29.0°F. Not sure what to make of that, and whether the NextGen expects some kind of reset in order to get an accurate reading.

[@BrenoAutoGarage]

Wow, that is serious stretch! Was it rattling on cold startup, or running poorly? I am not sure what to make of 29°F, but I will post a pinned comment when I get around to replacing the chain and scan to see what the baseline value is. I do believe it is normal to be +/- 1° on a new chain, at least that is what others online have seen. I do not have any VWs myself, I got the scanner to check this value after my mom sent me the CEL code scanned at a parts store in her town. I wanted to make a video showing my experience, but I am by no expert. I wish there was a dongle scanner like OBD11 for all car brands, very powerful scan and customization options you usually need dealer software to do. Using a laptop with Techstream for my Toyotas gets annoying.

[@Plus2-1]

This was on a 2013 Audi B8 2.0 TFSI allroad. No rattle, no symptoms at all. Ran perfectly smooth at idle and under load. No DTCs. I inspected the tensioner and could see it was fully extended, so I had the chain replaced as “preventative maintenance” given the state of the tensioner + the phase position value. I’ve determined the OBDeleven device doesn’t always play nice with iOS, in my experience anyway, and the functionality is just better on Android. The iOS app was misreading the camshaft adjustment phase position ° as a temperature value instead of degrees of rotation, so when its Units setting is “metric” you get the correct reading, but if Units is set to “imperial” the app converts what it thinks is a Celsius value to Fahrenheit. The Android app recognizes it’s not a temperature value just because there’s a ° present, so metric/imperial settings don’t change the phase position value.

[@BrenoAutoGarage]

@@Plus2-1​​⁠ Very interesting, thanks for the reply. Hopefully they will update the iOS app to work correctly, and until then everyone with the issue will see your comment.

[@bhpbones]

@@BrenoAutoGaragehello man, my exhaust intake was 0.3 and my camshaft phase bank 1 was: -3 is this ok? And what if exhaust is more -negative to? Do both have to sort of be as close together as possible? Many thanks

[@leo3325]

Is OBDEleven pro or basic version to check timing?

[@impactracer]

basic

[@arturts3296]

Both will do the trick

[@BrenoAutoGarage]

As others said, basic can read the data. You’d only need pro for customizing/programming. I have not tried pro myself.

[@juanbarbosa7275]

Hey could you help out i just bought the scanner but its not reading the phase postion b1 intake its staying at 0.00? It only reads the engine speed and load thats it

[@raulraul3417]

Hi, you solved it? mine is the same 0.00

[@BrenoAutoGarage]

I’m not sure, hopefully someone else will have a solution. I’m replacing the timing chain right now (took a few months to get around to it), I’ll have to play around with the app some more after that’s done.

With high hopes, i got an OBD device to check the status of the timing chain on my VW Golf 2.0 TDi. When I went to live data, the OBD software GUI didn't allow me to enter any value for the live data channel. Instead a list of live parameters is only what I could access, of which "Camshaft adjustment adaptation" was not listed. Camshaft position start of phase window, Camshaft position end of phase window, Camshaft adaptation intake bank 1 phase position, Camshaft slope position were the only options I could see in the list. I tried the app on both android and iOS and the options are still the same. I am on the free version without any credits or upgrades. Can someone let know what am I missing here. 1:42 1:42 1:42

Youre making a mistake, you need to bite the bullet and change the chain and tensioner, youll be sorry if you dont

[@Itsa_Mea]

Not yet but the tensioner definitely needs to be updated. -4° + would draw concern.
