  1. My T180 has 2 problems. After looking through various forums, it seems that these are common problems on this car. A misfire/hesitation around 2000 r.p.m. Above 2000 r.p.m. the turbo kicks in and car drives OK. Since the hesitation occurs at the point where the turbo kicks in I'm wondering whether there is a turbo related problem. A faulty sensor or leaking hose somewhere. Or even a fault with the turbo itself except that, when it does kick it it goes well. Car occasionally goes into limp mode with the engine light/TRC/VCS lights on. This usually happens when going down long, steepish hills. In fact there are three local hills where this happens in the same place about 90% of the time. I've checked the fault code when this happens and it always shows "Exhaust gas recirculation flow", even after fitting a new EGR valve. Possible causes that occur to me are: low voltage to the stepper motor, bad connection or broken wire. But why would these cause the fault to occur when going down hill? Could it be fuel related such as clogged fuel filter or dirt in the fuel? Or, could it be caused by the DPF - e.g. back pressure when going down hill? So I've done the following: New EGR valve. Replaced injectors with refurbished ones. - but not the 5th injector New MAF sensor. DPF cleaned. Any thoughts on these problems? I'm getting to the point where I don't want to throw much more money at it. Thanks for any ideas. Mike Brogan
