Just my opinion, in an open forum, where I can have my opinion and freedom of speech, whether my opinion is wrong or right, The engine THP EP6DT/S 156 and 175 share the same engine, as fitted in the BMW MINI Cooper S engine code N14, they have the same water coolant pump, thermostat and turbo coolant pump, both share Bosch ECU's and electrical control sensors, fuel injection systems etc etc, there is more common ground, than you might think!
It was and is simply my opinion, and I am free to express that, like I have already said, if Peugeot deem it necessary to take preventative measures, then they will, regardless of what I or anybody writes, to the contrary, on a publicly read open forum, which allows freedom of speech, of any individual, with their opinion.
I am not out to, or have called Peugeot a liar, it's my opinion from my technical understanding point of view.
If my comments/opinions on this matter, have offended or upset the Peugeot RCZ forum community, then feel free to remove them.
