I read somewhere on the forums how to eradicate chain noise on cold start up. I first noticed the whirring chain noise on cold start up in Austria 2019. Recently I have heard this more regularly especially near oil change time.

I tried the recommendation of turning on the ignition key and wait until the fuel pump stops whining. Wait a further 5 seconds and then start the engine. It promptly starts with no chain whirring noise. So far every time.

What age of 1.2 TSI if it is that? How many miles? Maybe go for VW502 00 oil, 5w 40 full synthetic non long life and change at fixed regime or sooner if you use VW 504 00 / 507 00. 5w 30 FS III.

How bizarre

Must try that even though ours makes no noise that worries me.

Can't understand what possible explanation there might be for that working.

Engine is 86bhp tsi with 75k on clock. It has the revised chain tensioner and 2013 reg. I have owned it since new and dealer serviced. The dealer has changed hands and also oils. Currently it has 0W 30W Castrol Edge. In its lifetime it has had Shell Ultra Helix 0W 30, Castrol Edge 5W 30W all Skoda filled

I would be requesting back to 5w 30 FS III then which was @nd still is the spec of oil for that engine. Personally if noise I would go 5w 40 FS which was and is still the spec if you want and as long as doing fixed regime oil and filter changes.

It's has gone into an independent garage today for oil an filter change. He uses 5W 30W for this engine so looking good

For best cold start-up filling of tensioner and lubing of chain, 0W oils should outperform 5W.

Why was 0w 30 FS III not the recommended oil back when they produced the Euro 5 engines. There are EURO 6 and

I would guess that there weren't any 0W30s on the market then which met the correct VW group specs.

Things evolve.

They did. But the recommendation never changed. Actually there were recommendations as the engines. Actually with the Euro 5 TSI,s VW recommended as engines aged you changed to servicing using 5w 40 FS and fixed service regime. the 40 better at higher temperatures more stable & better turbo charger protection. Compensating (after 5 years) for internal engine wear. The slightly higher hot viscosity oil helps maintain oil pressure and cushioning. Those were from VW not me, and not AI.

VW group specify the numbers like 502 00, 504 00, not viscosity.

& the VW 502 00 is 5w 40. which is what they do recommend after 5 years with the Euro 5 TSI,s. That is the not recommending continuing using the VW 504 00 / 507 00, 0w 30 0r 5 w 30. After all the Manufacturers warranty has expired and the Service Costs and running costs of Fleet cars no longer concerns them. Honesty being the best policy from them... Because Dealership like to keep it simple and buy in 2 oil specs 0w 30 FS III & 0w 20 FS IV and not the Non Long Life suits them but does not mean it suits the engines / owners,.

Got car back from oil change and as always after the service engine is as sweet as a nut. You would think that 0W would hit the tensioner quicker but 5W has more body. The consensus is that the tensioner is tired and at maximum adjustment so a replacement chain, tensioner and sprockets.

Nope, even back in 2024 (last saved list I could find) it could also be 0W40, 0W30 and 5W30, here's just the first few oils listed as 502/505 approved.

^^^ That is good, but VW specifically recommended the 40. 40 for the HIGHER STABILITY. so really the 0w 30 FS III is neither hear nor there. But the 0w 40 meets what they said. VW not me.

Where was that recommendation, and for which cars/engines?

Do not use AI mode. Use the key words VW recommendation euro 5 tsi,s oil 5 years +. VW 502 00 'Usually 5w 40 full synthetic. & they explain why. And that has been the case since 2014.

I don't use AI.

I just understand how VW group specify oils.

If there's an official VW group document you're referring to, I'm sure you'll manage to post it or link to it in due course.

Well you will understand way the made that recommendation within a few years of introducing the Euro 5 TSI,s and having so many issues. 1.2, 1.4, 1.8 & 2.0 TSI,s. Issues with higher than acceptable oil use with some, timing chain issues a premature expiring engines especially 1.4 TSI Twin chargers and 1.8 / 2.0 TSI,s. Long Life Oil, lots of short life engines.

Waiting for link or doc.

I can not link it just now, but a man of your ability can read it easily. Do a key word search. If i could link it because on a very poor internet connection.
