im no mechanic so can anyone tell me if they have heard this particular noise.in a petrol engine you would describe it as "pinking".when accelerating from say 1300 revs it makes this noise until you reach around 1500rpm.???

wha?
Lots of 150 CDTI drivers in here mate, but can you be a bit more clearer? Im not familiar with the pinking terminology.....and I have had a few probs with the CDTI so would be very interested to see what you mean. !
pinking is pre-ignition I believe
conny, does it do it standing still when revving in neutral or whilst accelerating or both?
A ticking kind of noise on hard acelleration, like I think someone described as wastegate chatter? ?? I dont know?
But on hard acceleration mine has a low down ticking, small enough that I ignore, couple of taps a second..when going up the rev range.
hertscol seems to have summed it up here.a ticking sound under hard acceleration for a few seconds,a lack of fuel? i dunno,ive been reading all about them egr units on here,booster sensor,third injector! christ im scared to death of reading any more its enough to keep you awake all night !!!!
Little bit of what I would discribe as diesel knock until its on boost right? They all do it and are even worse with a chip....I tested it on mine and is quieter when warm
