SWMBO Yeti is a 2014 1.2 TSI and has an occasional timing chain rattle on start up, only 50k miles.

 

I’m thinking it may be the valve in the oil filter, but I think I’ll get the garage to check it out when it goes in for annual service next month. Perhaps when the filter is changed the fault will disappear (or not).

 

If it’s not the filter, I was under the impression that they sorted this weakness out in 2012.

 

As it’s intermittent (about 1 in 5 cold starts) I’m wondering if that points more to the valve in the filter or the start of more ‘classic’ timing chain failure.

Going to the dealers on Friday for a service and investigation.

Fingers crossed all goes ok.

Well, service and MOT fine, but diagnostic for cam chain rattle - nothing found.
 

Hopefully this means the cam chain isn’t worn or stretched.
 

On the upside the garage didn’t charge me for this diagnostic as they didn’t find anything- which is appreciated, but on the down side it rattled a bit on starting it at the dealers to bring it home 🙁 so I don’t have much hope, all I want is it fixed, and any potential engine damage from a skipped chain being avoided.

 

I think all I can do is monitor this now and see if it’s the same / worse / better.

 

Theres a good VAG Independent nearby that could look at it too, so I may try them. 

I don’t know if there’s any particular TPI on this for a 2014 model (after cam chain issue was supposedly fixed).

 

If at first you don’t succeed....

Pleased the mot went well. Always a releif !! With the rattle, it might not be as bad as you think. You know how it is with noises sometimes, once you've heard it, you really tune in to it. Still, be worth getting a second opinion though.

Thanks for the comment, well it’s logged that they did an investigation - just in case.

 

Yes, I hate rattles and totally agree about once you hear it, but this is quite noticeable, so much so that my wife picked up on it! Seems to be quite random when it happens too, but mainly from cold.

 

Had the video of the underneath from the dealer - looks mint - 50k easy driving. I think the car would get frightened if it went over 50mph😀

 

I’ll feedback if and when I get to the bottom of it.

 

Thanks again

Similar problem with my 2013 1.2 tsi. When it is cold outside (below 5 degrees) I can hear the rattle on startup. Not always, sometimes. 

Changed the tensioner for the latest revision but I think it hasn't resolved the issue completely...
In this topic I described what we tried to resolve the issue:

 

 

@Madket Thanks for the link, yes I was aware of your thread and it makes interesting reading, I hope you have it pretty much sorted. There’s lots of info for this fault on the earlier CBZ type engines, but not so much after they beefed the timing chain up in 2012 as I understand it.

 

I don’t like to say this too soon, and have probably damned myself in doing so, but since the service (and initial rattle at the garage), it hasn’t missed a beat, and not rattled once, and it’s been pretty cold here (around zero C) so I’m rather hoping it was the filter letting back. Only time will tell, I have my fingers crossed 🤞 

 

Good luck and thank you for your post.

8 days post servicing and quite a number of sub zero days, and lots of starts, not a rattle yet.

 

Looks like it was a dodgy filter (or fitting).

 

I’ll be much happier after a month of cold starts with no rattle!

Rattle came back and diagnostic found stretched chain this time round. Had it all replaced at my cost £824 after a little negotiation with my dealer who dropped the diagnostic fee, so not too bad but who wants to spend that on a part which should last much longer and was redesigned due to premature failure. SUK were sympathetic but no offer of assistance, car is too old now. Not what should happen on a 2014 car with 57k miles (the rattle started well before this but after the 5 year extended warranty ran out of course) and with a full dealer service history, no wonder they changed to a cam belt!
 

So if you’ve a 2012 onwards 1.2 TSI engine with the redesigned chain (not the newer belt unit) then you are not immune.

 

PS car has so far been rattle free on start up and seems a bit quieter when running.
