Notwithstanding that we are basically French Car Lovers( ), it has been my experience that when it comes to quality mass production engineering, PSA are streets ahead of Renault - not even in the same ballpark. Apart from often apalling vehicle build quality, Renault engines in particular often just don't last anywhere as long. Engine technology can be excellent though...For owners of newer/fussier cars I would think twice before diabling the EGR system, for example it's thought that EGR faults are what leads to the demise of the Renault 1.9 DCi's.
Electrical probs can sometimes be horrendous... I have known folk to just dump the problem on some main stealer and buy out of the situation. That is not to defend PSA on occasion, just a general summing up. Anyone different ideas?
