Got my car remapped around 3 wks ago, and have noticed a high pitched whining noise when i accelerate, and it goes away when i decelerate, almost like a police siren but nowhere near as loud! Reckon this has anything to do with the remap? Also noticed today the smell of diesel when i was sitting stationary in traffic. Definitely not from other cars as i smelt it when i was stationary in the car park with no other cars around me! Any ideas? My dad had this police siren sound comming from his bora 150tdi and it needed a new turbo.
