Great Wall X200 Engine Problems

I don’t believe that what you want is out there, and can only reiterate past advice, buy a Patrol/Pajero/Prado/LandCruiser.

It all depends on the model and variant of the vehicle you’re talking about, but, generally speaking, the fuel rail pressure sensor on a turbo-diesel engine will be somewhere along the fuel rail. But, even if you know for absolutely certain that this sensor is the problem, we have to advise against any amateur mechanic taking on this, or any other, job that deals with the fuel system. That’s because the fuel systems on a common-rail turbo-diesel run at incredibly high pressures. So they’re dangerous things to fiddle with.

In some cases, the pressure could be enough to slice fingers off. Which means you have to know the exact process to follow in order to bleed off any residual pressure in the fuel system (even if the engine hasn’t run for days) before you can safely tackle jobs like this one. Leave it to the experts, in other words. Also, a specialist is a chance to be able to make a more accurate diagnosis than the one given by an online forum of dubious credibility.

You can use a 0W-40 A3/B4 or a 15W-40 dedicated diesel oil, and a Ryco filter. A local auto retailer should be able to help.
