Hi all! I have a 2008 L200 warrior model and recently when driving lights have appeared on the dash which I think are traction control lights and the jeep shakes and there is a massive drop in power in addition the engine management light also comes on causing further power loss which I presumed to be the EGR but having checked it and cleaned it out the problem still persists. The oil light has also appeared recently and I've checked the oil level several times and it's fine. If anyone knows anything about these things your help would be greatly appreciated.
Thanks in advance.

Firstly has the truck had a full de Coke as that is a service schedule of about 30000 miles
Secondly it could be the suction control valve
To carry on is the truck fitted with a power upgrade module if so unplug it and return it back to normal
The list of possibilities is pretty extensive
