You may want to just print out the idParts page on the 7v Etecno1 gps as it says they are a direct replacement for the OEM 7v ceramics and present same to your mechanic. FYI if you are anywhere near Alice Springs check in with Mark Kapalczyski who is stationed there with the US Air Force and knows all about the CRD.

I live in Sydney about 3 to 4 days drive to Alice spring from here but I will show him that I'd parts page he has just given me the jeep dealers contact to pick it up so I will show them and see if I can change there mind on the subject I'll let you know how it goes thanks

Glow plugs fitted all good so far no module needed but jeep still pulsing when in park only was really hoping the glow plugs were the cause of it but unfortunately not might have to look in to swapping the fuel filter hopefully it might be blocked and it's an easy fix
Can't say this enough thank you
