Went onto the Bosch website and the recommended GP were 0250202038 which is 11v rated.
NGK recommended Y1031J which is also 11v.
However these seem to be rated at 11v, and I am pretty sure I have 7v.
Is there an issue running these Bosch GP 0250202038 in my 2006 CRD ?
The weather here in Brisbane never goes below 10c.
The 11 volt plugs are only for the Export 2.5 CRD from 2002 to 2003 I believe....definitely not for 2006 CRD!
There is no glow plug controller on these early 2.5 CRDs....two fat relays supply 12 volts direct to the plugs...drops to 11 volts by the time it gets to the plugs themselves. The ECM then rapidly switches the plug ON/OFF with Pulse Width Modulation. The ECM does not check the plugs at all...merely checks that the relay coils are not open circuit or shorted out. Pretty basic system that works fine. I saw some posts from Austrian KJ owners who were not happy with the 5v/7v system on their newer CRDs and had developed a system to backtrack to the 11 volt plug system!
My 2002 Export 2.5 CRD uses the 11 volt plugs.
Some CRD owners like to use 5v plugs with the 7v controller tune in the cold climates.
