2011 77 TSI Engine Rattle on Start Up.

[pontiff]

I have got the rattle again, and it has only been 9 months and I have driven 17,500 km. I might have to take it in again.

The receipt mentions the part has a 2 year warranty, so hopefully it should be ok.

Let us know as mine does too now.. Probably the same timeframe too, few more kms tho...

I moved around one of the fuel lines and ever since then I haven't had the rattle on start up. I don't know if this is just a coincidence, so I will check it out over the next week or so and will keep you posted.

How did you go... just curious as mine is doing it again still..

I finally had mine done about two weeks ago just before the warranty finished and on 44k. My rattle was only very intermittent though.

Hey all,

Quite interested in this thread as it sounds as if I am experiencing the same thing.
In April this year I took ownership of a Polo 81tsi Manual. Not a thing out of place with it. At around 5,000km I started noticing quite a loud rattle on start-up and it predominantly occurs when it's a colder morning or night.
So sounds identical to what you all described.
Does the 81tsi engine differ in any way that may mean that it's a different issue?
Or is it the same engine?

The 81TSI is a 16 valve engine (4 valves per cylinder) while the old 77TSI was an 8 valve engine (2 valves per cylinder) and I'm fairly sure while the 77 was timing chain driven, the new 81 is timing belt driven so the rattle must be coming from somewhere else. I may certainly be wrong but that's my understanding anyway.

Just bought 2011 polo tsi with 110ks on the clock, everything feels as tight as a drum but seem to have the infamous death rattle sometimes on cold start sometimes when warm.
The test drive was from Gympie to Cairns , nearly 1600ks drove like a dream. Do I need to be concerned, really appreciate any feedback. Thanks.

Thanks for the info regarding the engines. I'd also thought that I had heard the 81tsi is belt driven but wasn't sure. I'll take it down to the dealership and hope that I can replicate the sound in front of them.

Hey pontiff, I still get the rattle but its very random. So I'm afraid if I take it down they might not hear it.

Del, you definitely need to be concerned. Get it replaced before it takes your engine out with it.

I noticed the rattle on cold start when I bought the car, price was right regardless and I purchased it. About a month (2000km) later I started it up one morning and it was making an almighty racket. Turned it off, called VW, tried again next morning- same noise. Had it towed to VW. Very lucky not to have skipped teeth.
