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.
