1.2 TSI Cold start noise

Post by Niknaks »

Hi all,
I have a 2015 1.2 TSI Polo.
It has only 48 000km on and regular service with the agents.

When I start the car in the morning it makes a clattering noise and bumpy idle for half a minute.
Why?
Should I worry?
Is it the cam chain and tensioner?

I am almost too scared to drive the car which otherwise goes fine.

What do the experts think? And dankie in advance.

I believe this is normal.
My wifes 1.2 TSI does the same thing.
The owners manual actually says the motor being noisy is normal for the first couple of seconds

I'm certain that will be due to the oil not reaching everywhere immediately at start up as it's still pumping. But 30 seconds seems a bit too long, 2-3 seconds would be normal in my opinion

My brother, best mate and I have the same car.

2017 = 43 000km
2015 = 101 500km
2014 = 175 000km

They all do the same thing on start up but the duration and loudness seems to get worst with age. The 2017 one is much less noisy on cold start and lasts a few sec only vs the 2014 (almost sounds like a diesel for a few seconds but then gets softer and softer until normal idle)

Hi
I know this is an old thread, but did you find out if anything was wrong with the cold start? Carbon on intake valves? Do you smell some gas from exhaust? Increased fuel consumption?
