Timing chain

[lil3520]

I have a Mk 5 Ibiza 1.2 Tsi Fr 2014 plate.
Just had a 30,000 mile device at a seat garage.
Told I have a timing chain and it does not need changing.
Is this correct ?

Yes if it is the older version of the 1.2TSI engine - the older version has a chain driven camshaft and the turbo is mounted at the front of the engine next to the radiator, the newer version has a belt driven camshaft and the turbo is mounted at the rear of the engine next to the passenger cell.

Also, the older version has an almost vertically mounted oil filter that is just an element that gets covered by a black plastic shell with a low torque figure on its end along with a hex area (for removing it) roughly on the top of the engine, the newer version has a lower mounted disposable oil filter mounted horizontally at the front of the engine.

Thanks for your reply.

We have a 2011 1.2 TSI with almost 60k on the clock and I'm planning on changing the chain tensioner this year as they're made of chocolate apparently. Not sure whether to do the chain as well, thoughts anyone?

Maybe have a look at which version of chain is currently fitted to that car, I believe/think that there were at least 3 versions of chains fitted to that engine, namely useless and weak, not very handy and weak and completely different design so meant to be okay. If you have owned that car from new you will know if it has had any corrective action in that area. There is a picture on line of the different versions of chains so if you don't know the history of that car, you can work out which chain is fitted - though you would need to remove a cover! Another thing, I think that when the best chain was fitted, it was necessary to replace the chain wheels as well as the tensioner.

Great post, thanks for putting me onto that RUM4MO. I found the info here:

I think these two links, give the best idea of what is needed, though they need translated from Italian.

They have been copied from a Skoda forum.

I found another good page with some useful info which is in English here (second section down):

http://ukcar.reviews/skoda-roomster-5j-2006-problems-recalls/

Our car has the chain cover 03F 109 210 C and despite a huge amount of searching I can't find out whether that means it should be ok or there's still an issue. The car seems to be after the critical June build date but the cover listed as optimal is 03F 109 210 D, so it's a bit confusing.

Remember here that I am just commenting on what I've bumped into on the Skoda/Volkswagen/SEAT owners forums, but having read that last posting you made, ie its link, I thought that the general understanding of what happened with say older engines was:- initially fit new chain, later:- fit newer chain and some other bits maybe including a new chain cover to minimise chain jumping the sprockets - officially end of story, this was the only action that dealer were allowed to do as warranty work on older engines. Some time later, Skoda/Volkswagen/SEAT cars started to get delivered new with a few more proper fixes to these engines, which might even have altered the engine version code - but these proper fix parts were never intended to get retro fitted to older engines being worked on by main dealers - this decision seems to have been made to minimise parts and labour spend on warranty works, so save Skoda/Volkswagen/SEAT lots of money! Now, what I thought that the Italian VW forum link was mainly about was, an owner grabbing the bull by the horns and fitting that set of parts, which I don't think were being made available by all marques, as a kit of bits to properly sort out an older engine. If that makes sense?

My interest mainly was, I was about to or had just taken delivery of a newer small engine car from VW - so I was watching this progress with interest. Basically to make sure that VW etc were standing by their customers, just in case something similar started to happen with the belt driven engines.

Maybe it depends on how long you intend to keep that car, I'd always find it very temping to "leap frog" the cheap and cheery VW "keep us out of jail" fixes and sort things out in a better manner if I was doing that work myself and keeping the car a while, really for peace of mind maybe.

What I can make of all this goes as follows:

- Pre 11th June 2011 engine (codes up to 'CBZ 462 774 M' & 'CBZ 714 253 S') produced with the timing chain set 03F 198 158 which was the original set with the problem chain that can elongate and result in engine failure.
- Post 11th June 2011/Pre 7th November 2011 engine (codes after 'CBZ 462 774 M' & 'CBZ 714 253 S') produced with timing chain set 03F 198 158 A which comprised of a reinforced chain and a new chain cover. The set was also made available as a repair kit for the pre June 2011 engines.
- Post November 2011 engine (codes unknown) produced with revised engine block (03F 103 101 B) had timing chain set 03F 198 158 B which comprised of a wider chain, new chain guides, new tensioner and an uprated upper sprocket.

The information that is not clear is at what stages the chain cover was implemented. From what I can gather:

- Pre 11th June 2011 engines had covers 03F 109 210 B
- Post 11th June 2011/Pre 7th November 2011 engines had covers 03F 109 210 C
- Post November 2011 engines had covers covers 03F 109 210 D

It could be that the post 11th June 2011/pre 7th November 2011 engines also had covers 03F 109 210 D introduced onto them later on but before the post 7th November 2011 engines (with timing set 03F 198 158 B ) due to having the addition of anti-slip teeth. However I'm guessing teh 03F 109 210 D cover is for the post November 2011 engines simply because there were so many changes to them, but there is no mention of a new cover in any of the information provided.

Could anyone with a post 7th November 2011 engine verify what the timing chain cover code is? Does anyone have a post 11th June 2011/pre 7th November 2011 with an 03F 109 210 D cover? The engine build date is written on the top right hand side of the engine number sticker on the back of the intercooler and the timing cover code is written on the bump just above where the top section of the accessory belt runs.
