Then I got off track reading about the Benz gearbox as several codes pointed there - Benz expert was pretty sure I was experiencing a common Benz box fault due to the limp mode but diagnostics couldn't be 100% sure - so didn't go down that road.
Ended up being poor connections in the main wiring loom that starts out under the battery carrier. Loom opened up, all connections resoldered, and so far so good, no more codes. There is a Jeep service bulletin for poor connections.
I've fixed numerous issues with cars over the years but never had to deal with this before.

Hello,
I have the same problem
Error Code P0235 on 2004 Grand Cherokee 2.7 CRD Overland
Intermittent: Sometimes engine light comes on when I start the vehicle other times not. Sometimes no power when I pull away other times it is fine, sometimes lose power while driving then stop and pull away it is fine, sometimes lose power then switch off and on it is fine. Sometimes gears wont change then switch off and on and gears are fine (this usually happens if I pull away and not let vehicle warm up, not often). Loss of power and engine light is concerning. Also having problems with battery been drained overnight.
my English is very bad. How did you solved it? Show me the picture?
Or tell me step by step?
Regards,
