Sounds like a absolute beast when you put your foot down, but why when the engine has warmed up does it sound like a diesel??? Any ideas guys??

Compression ratio + direct injection.

It's due to the direct injection system on the TFSi motor  :happy2:

Doesn't sound exactly like a diesel but agree it doesn't sound like the average petrol engine either.

Isn't it the HPFP that makes the noise?

First ones tho on the AXX engine code were known to have the ''cam chain & tensioner'' fault which made them really sound like a diesel.My last 05 did & they had to be replaced.

Mine's on an 06, do you think if I had them replaced then it will make a difference?
