thanks sean i did read a similar thing in the archives so its main dealer only and does any one know the rough cost the customer is a bit reluctant to take it to our local dealer as he did go in the other day before he brought it to me and the technician i think thats what they called him told him it was the glow plugs and it was a common fault on these diesel engines he was a bit embarrased when the customer told him it was a petrol engine ?
