2011 CC - ruslting of leaves in turbo engine ?

[kribnutz]

HEllo everybody

I am excited to be the new owner of a 2011 VW CC. So far it has been a great car and there is absolutely nothing I don't love about it! I just have this one question tho:

I hear a 'rustling of leaves' kindda sounds from the engine at around 2500ish rpm. Is this the turbo kicking in ? I don't have prior experience with turbo engines so sorry if this sounds stupid.
The Audi A3 turbo apparently has the same noise but I don't know if the CC and the A3 have the same powerplant so....Can someone help me out here ? I won't have peace of mind until I know that is normal or something that can be fixed.

Thanks a lot

Welcome! This topic is a big discussion on here actually. There is a thread dedicated to it. It's the wastegate actuator arm rattling under partial boost. There is no fix at the moment but it's a totally normal noise for the 2.0TSI engine. Adding a weight to the arm will reduce it slightly. I would leave it alone for now.

Thanks a lot mate! At least it is not just in my car - good to know!

Another thing that I just noticed - the rear windows sliding up into the rubber grooves once the door is shut produces a slight 'squeak'. This is not the case with the front door windows though. This kindda happened after a really cold night so I am guessing something shrunk and the fitting became tighter ? Either way, is it again something to be worried about ? Would something like that hurt in the long run - maybe the 09 and 10 CC owners would know something ?

Get some silicone spray and spray the rubber seals. It keeps them happy in winter and prevents them from freezing and becoming brittle.

Nitro is there a certain brand of silicone spray you recommend for the rubber seals?

Any spray silicone will work, but German silicone from VW works the best. EXPENSIVE but works great. head to your local dealer to grab some.
