    Haven't read of any problems as such, apart from if you have a 170 and you get it mapped to over 200bhp without removing the DPF

    Otherwise the exhaust gasses get over 1000degrees and basically melts the sensor (so i've been told)

    So to map a 170 over 200bhp to about 225ish you need to remove the DPF

    1000degrees! that will melt the entire engine and probably the car! once mapped a diesel car usually produces more smoke (depending on the map ofcourse). The role of the DPF is to clean the smoke and it has more smoke to clean, hence get blocked more easily, but you can usually regenerate it by driving at 3000prm in 3rd gear for a few mins.

    see link for more info.
