Yea there is 114k on the clock now. I had to buy a new transfer case as last one cracked. The car is going great now so want to try and prevent any more mishaps. I will get the glow plugs changed at the same time doubt they have ever been changed and the mechanic did say one of them was flagging up on his computer but has not threw up a EMLI had my 2.2D autom. oil changed by the local GM dealer. I think had some 120tkm on the clock at the time. They just changed what came out when opened the drain plug. It is easy to do annual services by yourself but everything else i had professionals to do. You wont change autom transmission oils more than maybe 100tkm intervals. Same with transfer box and rear end oils.
