Polo 1.2 TSI Problem

[wolfie]

Have you had the cam shaft adjuster recall done?

What cam shaft adjuster recall?? First mention I've heard of a recall.

First, I could be wrong, but I thought that the turbo actuator issue was only with the early 1.2TSI engines, ie the ones with the turbo at the front and chain driven camshafts.

Camshaft actuator, there was an issue with early versions of the later belt driven camshaft engines, the inlet camshaft has variable timing achieved by altering the relative position (very slightly) of the inlet camshaft drive pulley - these pulley did end up slackening off and dumping oil in some cars it seems. There is a picture online somewhere of the old and the new pulleys, but I think that these pictures only show the interim retro-fit modified pulley and not the eventual fix as implemented at the engine factory - well that is what I am hoping anyway as I've had a look at the inlet camshaft drive pulley on my wife's August 2015 Polo 1.2TSI 110PS and it does not look like the "newer" version in that online article.

If you are concerned, partially remove the drain belt top cover to see what pulley is fitted to your car and if there is signs of oil escaping from it.

Edit:- I'm sure that this issue was originally brought up on this forum some time ago. wolfie while I quoted your posting, I'm just replying generally as I know your car is not involved with the issue you quoted!

Cheers, I'm just interested in anything and everything Polo engine wise at the moment. Agonising a little as to whether I just dig deep and get the cam chain update done "just in case" Or cut my loses and move on. Turbo actuator was done at the first service on mine iirc. (mine wasn't rattling anyway)

Any and all opinions welcome.

Also there's is a TPI for the turbo actuator on the belt driven 1.2 tsi for the turbo actuator sticking due to corrosion between it and the wastegate rod

Ah cheers. What sort of issues does the sticking actuator cause?

[BigDaveGti]

Usually a lack of power or an EML

Oh brilliant - thank you! Now something else to prepare for, so hiding the turbocharger at the back of the engine has not lead to the linkage keeping clean, I thought that I had read something about this turbo being controlled in another way, though how much "another way" as I'd expect the final control link will be a waste gate!

Cheers. Do TPI's include software updates??

[BigDaveGti]

No software update, usually a new actuator and a special grease for the contact points to stop it from happening again

TPI = Technical Product Information which is VAG's name for a potential corrective action alert, I think that they can result in TSB which are Technical Service Bulletins - which will outline the actual rework procedure in the dealer workshop.

Are the TPI/TSB's accessible to Joe public, or do VW keep them under their hat? I was thinking would they be available via ErWin?

I'm sure that they do not appear in the public domain, I seem to remember that the VW website allows you to check if your car is the subject of any recalls, but remember most of these TPI/TSBs are not safety related recalls so the only place that you will be able to view them is on forums where so clever person has collated this info for "that" model.

ErWin - maybe, I've never paid for access to that - yet, so maybe that is the way the grab the info and post it up, I suppose that if we all dumped a small sum of money into a pot, someone could collate and keep up to date this info on this forum. Maybe a reason for this forum to offer a "higher" level of access for certain "services" - I'd be willing to pay for that potentially useful info.

In general I was all against any of these forums asking for money, ie an annual subscription, as a lot of us supply answers as well as asking for help, but if paying a small annual charge lead to being able to check up on TPI/TSBs then I'd back that! The Skoda forum offers a "freedom" higher level of access to certain things, I paid that once as it was meant to give you access to dealer techs for advice - all the questions I asked never got answered as maybe at that time I was finding out issues before they became common knowledge - so I gave up on that though the forum owner did try to get me back on board, but I felt that I was giving maybe 95% and asking for help maybe 5% - so why should I be paying as well.

Edit:- the way I see it, if car manufacturers did not experience many design/build faults, then it would be okay to hide these issues and take care of them during normal service visits - of if a car did not show as getting "the fix" within say a 24 month window it would get officially "notified", but, if at the level at which lots of car manufacturers are currently operating with design/build faults, we as owners need some "heads up" on all these potential issues - although that would mean too many folk submitting their cars for investigation/FOC rework, just because they had heard about these problems, but as I said earlier, if that model of car was not regularly being the subject of many design/build faults then that would not be happening - so buck up VAG and others, we have paid our money!
