Good point sir bvnzn. For the diesel quality, I don't think it's of poor quality though because I regularly top-up at Shell. And sometimes even the V-Power diesel (which I assume is cleaner than Fuelsave)
As I said, the car is well-maintened and I know it's properly driven (I have the MX5 for aggressive driving
) I guess it's just the lack of cleaning of the EGR valve then. It's been about 4 years since I bought the car and only now did it break. And with all that time, not once was it cleaned. So I guess it's that then. As for the changing every 2 years, I think it's one of those schemes to get you to trade in your car for a newer one that they say has a supposedly "better" engine design.
Thanks for helping sir bvnzn, I guess I won't be selling it then. Either way, I'll be buying a new car this year (I'm looking at you Ford Ranger/Kia Optima/Mazda CX5/Honda CRZ). I just wasn't sure if I would sell the Fortuner so I could get 2 cars for 2012
