G'day All,
My 93 Defender 200 tdi has developed a noise similar to Pinging in a Petrol motor,it only occurs under load around 90k's in 5th gear.Because it doesn't do it all the time it is hard to pinpoint,but,it seems to be up front somewhere.It doesn't seem to effect the performance at all but is a worry!I'm sorry it is a bit hard to explain,but I'm hoping someone might be able to help.
Thanks
