Cool, well i'm due a few hundred quid soon so will get that done asap. I took the maf off and gave that a clean. The torx head with the bit in the middle was most annoying so just fired loads of carb cleaner at it! Noticed a bit of an improvement but still don't think it's as rapid as it should be. Also the car does not rev past 6.9k (sorry to try and be so exact lol) It's not reaching the limiter which is 7500 I think? Presume this is down to the variator also.
Since cleaning the maf though I have noticed an improvement of the engine though, don't think it's 100% though. Got a rolling road day coming up soon so hopefully can get the variator changed before then!
