Recenty had car in for some fixes:

The 2krpm 'mooing' sound from the engine (Oil pump pressure relief cylinder - now given special coating to stop resonnance I think) That seems fixed.

I also had a fault which no-one else seems to have complained about, in that the remote locking had limited range. Security system replaced and keys re-programmed. Also fixing the problem.

Engine power seems OK, though I might have just got used to it. Maybe I should have a drag-race with someone to compare.
