Hi,

I think I can hear the timing chain, at cold start.
I noticed it in the first 2 to 3 seconds when starting the car. - Then the sound disappears.
The sound is best described, a bit like a cold diesel engine.
I can not produce the sound by turning on / off the car. I have to wait an hour or more before I hear the sound again.
The sound is only present at the first cold start.

It's a petrol engine - 1.2 TSI 110 hp

Is anyone else experienced this?

They all do it, I sound like a Skoda Techie now, but they do. Mine does and my old Monte with the 8 valve TSI engine did it as well, it'll just be at cold start until the oil has circulated.

Im afraid the timing chain is a belt so it should be quiet. What you hear is probably the hydraulic valve tappets before oil pressure is up to normal.

I was close anyway, i said I sounded like one not was one  :clap:

Of course there is the whispers about issues with the variable timing cam pulley - bolts slackening off causing nasty things to happen, some early 1.2TSI 110PS Polos were quietly being recalled, though I'd hope that that problem had been sorted out by the time Fabias started using that engine, I'm hoping that my wife's Polo with an engine built in May 15 has a modified pulley - though it looks identical to the faulty ones!

Every car I have ever had, back since they replaced horses, has made a short-span rattling noise at cold start, just for 2 or 3 seconds. Some more than others. I have always thought it was the oil getting pumped up from the sump to the valve gear and all around the engine's moving parts, and I have always waited that short time before putting any stress on the engine. I have a 1.2 TSI 110 and it sounds just like you say, a slight rattle on the first cold start, and i just accept that it takes a short time to get the sump oil up to the top of the valve gear. I don't think that is unusual or a problem, but I would not power the engine until it has stopped.

It's the automatic tappets they are noisy till the oil is pumped up to them more obvious after an overnight stand Joe

Sorry to hi jack the thread but it didn't seem worthwhile starting a new one as I have a noise query as well ! Please ignore my ignorance regarding anything mechanical only my new fabia 1.2 TSI 110 makes a sound like a tapping on metal not only when I turn it off like my Mini used to ( I'm told its either the exhaust cooling down or the "block" cooling as metal expands and contracts with heat ) but I hear the same sound when I stop but leave the engine running so that would seem to rule out anything cooling down !

When I knelt down to try and hear where the sound was coming from it bizarrely seem to eminate from underneath the car as well as the engine bay, but it seems to take a little while for the car to warm up before the noise starts.

I was told that the 1.2 TFSI is a cam chain NOT a cam belt? I particularly asked this as I don't want the cost of cam belt renewal.

Can anyone confirm please?

It really depends on the engine type, which relates to the engine age, all the current range of 1.2TSI are belt driven, original 1.2TSI are all chain driven.

If you have a mk3 fabia with the 1.2 or 1.4 tsi then it's belt driven not chain. The mk2 fabia 1.2tsi were chain driven.

Hi James I have the mk3 1.2 petrol tsi any idea at what mileage the belt has to be changed. On my old Fabia mk1 1.9 diesel estate it was 60k and the advice was to change the water pump at the same time is that the same advice for the new car Joe

hi Joe,

I don't know the change intervals on the latest generation of petrol engines but I will find out for you.

The water pump is driven off a separate belt on the opposite side of the engine so replacement is only required in the event of a failure.

That's good news the water pump on my old car seized up managed to get home (not realising it was driven by the timing belt) Garage towed car in the teath on the timing belt had all but disappeared fortunately no damage to the engine Joe

PS my daughter has the old car now still running well after 100,000 miles

change interval appears to be at 160,000km with no specific time scope mentioned.

If you have a mk3 fabia with the 1.2 or 1.4 tsi then it's belt driven not chain. The mk2 fabia 1.2tsi were chain driven.

 

Is Fabia MK3 with 1.4TSI really available somewhere or is this a typo?

typo, a better way of putting it should have been: if you have a 2015+ vehicle with the 1.2 or 1.4 tsi in it then that will be belt driven.

That's pretty annoying as the dealers told me it was chain. I must admit I never checked but I don't think I would have to. Hopefully the plan they advised will allow me to trade in for another new car in about 2 years time.

Lets be cynical and say for the next car it will be a chain?

 

It can be strange how our logic works, "current engine uses a chain = great one less thing to worry about" - no, VAG messed up again, "current engine uses a belt = great no stretching or duff chain to worry about" - well let us see how far the recalls go for the issue with the inlet camshaft pulleys coming apart!

To be honest, I don't know of any issues, my reason was purely I didn't want the cost of renewing a cambelt, it's a big cost and in my mind it was just the idea that a chain won't need doing.

I don't know what the change of belt requirements are but hopefully I won't be affected if I change the car in about 2 years and leS's than 30k miles.

It would only be a issue if I have to keep the car longer.

I asked my dealer who said that all 1.2tsi engines are chain driven. Who to believe?

believe me! the later 1.2tsi engine is belt driven.

edbostan,  

what kind of 'dealer' did you ask, (not a Hash Dealer?)

was it a Car Salesperson,  or a Service Desk person or a Trained Technician in a Skoda Dealership?

 

With anyone standing or sitting around in the Showroom i ask them what their Mechanical Qualifications are and would 

they like to put their answer in writing and give their name.

 

Many do not know what comes as standard or as an option, let alone about the Engines Specification.

The Hash Dealer is liable to know more about the car you own.

The later EA211 as fitted to Fabia III 1.2tsi and recent Yetis 1.2/1.4, Octavia III 1.2/1,4, Superb III 1.4 and 3 cylinder version in Citigo (non turbo) are all cam belt

 

In fact despite the similar power outputs the engine is TOTALLY different in design. On the tsi If the exhaust/turbo position on engine is at the front of the car it's the earlier chan cam, if the exhaust/turbo is near the car bulk-head then it's the EA211 belt cam
