Nissan Problems

If we were in the USA your car would be called a ‘lemon’ and you would be getting a refund or a replacement car. Unfortunately this isn’t America and we have pathetically weak consumer laws and an even weaker body (ACCC) overseeing them. You could try to negotiate a deal with Nissan, who I don’t think have a leg to stand on, or get a lawyer involved.

It’s against the law to tamper with an odometer, but I’m sure it does go on. If you’re going to buy a car like this you need to have it thoroughly checked by a mechanic who knows them well. An experienced mechanic should be able to tell if a car’s odometer doesn’t appear correct.

The car’s electronic brain has observed some issue with the engine. Take it to a dealer or a mechanic with diagnostic gear and they should be able to isolate the cause and fix the problem.

Without knowing the cost of labour in Qatar the cost seems about right if you’re going to replace the transmission.

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

Unless it’s a massive leak that drains the oil from the engine, which is most unlikely, it won’t affect the engine.

Get it to a diesel mechanic, but if you can’t check the fuel pump.
