W205 C63 - Sqeaky exhaust cure?

[Kiwi79]

Test drove a C63 AMG W205 today and greatly preferred it to the W204.

One iritating niggle was the presence of a squeak when blipping the throttle stationary in switchable exhaust "open" mode in sport+. Is this an easy fix as I think it would annoy me during ownership (Garage could not say at the time).

Car is 2017 pre facelift estate

Thanks

You might be able to lubricate the valves, but usually when they start to do that, they’re not long for this world.

Be aware there’s to way replace them individually, you’ll need to buy the bit of the exhaust where the suspect valve sits (or possibly the entire thing from the cats back)

Thanks for the reply. Hmmm sounds worryingly expensive!

My local Mercedes Indy spray some high temperate grease stuff on the valves when it goes in for its annual service as a preventative measure. They have quite a few C63's in their care and they say it works wonders.

Can't help more than that I'm afraid.
