I own a Pajero 3,2 DID turbo diesel of year 2001. It all started when I pulled a small boat trailer. I connected the trailer lights to the hook plug and the left indicator was short-circuited. I removed it and the car indicators worked OK. I drove aprox. 5Km and delivered the trailer. On my way back the car started "Knoking" and lost power at low RPM. For example, when I stop at the traffic lights, it has hard time to accelerate eventhough the pedal is squeezed to its end! I parked it in my garage and left it for the night. Next morning it started very difficult (I had to press the throttle and after a lot of "knocking" it starts, but it is so weak that it cannot climb the garage ramp to get out. However, at higher RPM (>2000) it works like normal, it even reaches 200Km/H on the highway. I took it to a garage, where they changed every disposable material (Air filter, Oil+Oil filter, Diesel filter, Cooling liquid, etc.), The problem still persists and I took it to garage with OBD scanning capability. It's been 3 days now and they chew their words: We get 3 error messages two for emission sensors and one for can-bus communication error. We do not know what is the exact problem... we checked the cables and connectors ok and probably you need a new ECU (this really scared me, since everything else works OK and there was no MIL light on). Today I decided to pick it up, since I am afraid they do not know what they are doing. The closest Mitsubishi representative is 300Km from here and I am afraid I will mess with more delays and expenses. Can anybody help on what might be the problem? Thanks a lot.

After the trailer hitch incident and all , did yu atleast inspect yur fuse panels for all the fuses? There are common fuses that run 2 or more item that is not gegtting adiquete power. This could be the issue since there is a communication error betwen the ECM and BCM or an other control module.

No, I did not check, since all tail-lights etc. work fine. Following your advice I checked all fuses, They visually all looked OK, however with help of a multitester I located and replaced a suspicious one (the "legs" of the fuse were moveable without indication on the tester). Now everything works OK. I saved a lot of money (getting shivers on the ECU replacing idea...) and I want to thank you for the advice that actually solved the problem.

No problem at all. We are all here to help each other. So glad yu got yur issue sorted and everythin is well.
