Guys / Gals,
Been having this engine noise since i got my car, (tdi 140) now when you let off the power on boost you get like a cricket tuk tuk tuk sound like something in the let off valve winding down (other turbo tdi and petrol ive had you can hear the re circ valve sigh at this point) and when having the engin under load it makes the same noise but constantly (tappet sounding) until you let off and on again then it goes.
Any one else had this at all? dealer said it was just because its a tdi but im not that stupid, just sounds odd to me.
Thoughts appreciated please, its worrying me.
