I found this on another site,
There a 2 types of engine listed like this.
From January 1994 - September/October 1998 there was the GEMS (SAGEM) engine, which has the black rectangular box on top of the engine. After this period there is the Bosch engine.
So from Nov 98 it was the Thor/ Bosch, Motronic Engine Management System. (MEMS).
Does that sound right?
Motronic is Bosch not GEMS.Gems is bosch Thor is motornic !
Yes my mistake bloody petrolsMotronic is Bosch not GEMS.
The change date is Aug 1st 1998,this is the beginning of the 99my for LR,any petrol P38 with XA,YA,1A or 2A before the last six numbers in its vin will be Bosch Motronic injected.Apart from some NAS special edition ones from memory.
