Recommended Tech in PE?

[StangV2_0]

Morning Gents,

I purchased an '09 Pajero Sport 3.2 on Friday. Very clean and with full service history on 168000km. I replaced the shocks and I am loving it.
When I engage 4H I have the flashing lights indicating an issue with engaging front diff.

I have read many threads last few days about the 4wd system and what it could be. From a leaking vacuum pipe or faulty vacuum pump to a problem with the actuator or even a fuse.

I can't seem to find any obvious problems and want to take the vehicle in to get it diagnosed. I just wish to know where the problem is and then if possible sort it out myself.

But I am a bit hesitant taking the vehicle into the agents. No one particular reason but was just curious if anyone here can recommend an alternative persons in Port Elizabeth who would be able to look at this for me.

Thanks in advance.
