Recently purchased a 2008 200 Sahara. Drives mint and tows great. however I’ve not been able to put in 4 - Lo. Following lights come on dash- vsc- engine- ! - and the 4 - Lo flashes constant. Left me stranded as I it wouldn’t go back in to 4 hi. It’s in the workshop atm getting new actuator but that hasn’t fixed the problem. What a bummer.

The symptoms (not being able to get into 4lo) could be a lot of things unrelated to the drive train. Evap codes are a typical thing that causes this and all you need to do is clear the codes with an OBD2 reader. The first step is scanning for codes.
There is more in this thread than just actuator info.
Transfer case actuator issues are not uncommon on the 200-series. Not much documented solutions other than exercising the mechanisms regularly. Here's my attempt to provide more information on where and what the actuator is, how to service the transfer case actuator motor, and potentially provide some fixes.
Two main parts siamesed together that compose the transfer case actuator which is a plastic housing hanging off the rear:
1) Upper motor and rod is the center diff lock actuator/gearset
2) Lower motor and rod is the Hi/Lo actuator/gearset
Access is pretty easy and...

Diesel or petrol?
That could really change the facts on emissions as a cause. Yes very different evap strategies, but a lot more complexity in the diesel exhaust system.
Either way please post the details and results. Anything helps the knowledge base here, even if most of us are in the states with the 3UR gasoline engine.

Does it have the oem rear diff lock? If that one is blocked it can also cause the problem.
Oh another possibility is the sensor for the diff lock. If the motor is spinning but the sensor doesn’t give info it will also get stuck there. Easy to bridge it since it is a normal two wire NC sensor.
