I have an 04 plate scenic f9q 212 engine scenic,in july last year the turbo blew on the m6 without warning and since fitting a replacement,which only lasted 500 miles i have had nothing but a catalogue of errors,i was in dispute with the turbo suppliers and after a prolonged period managed to get a replacement f.o.c..in the last week i have had that turbo fitted along with a new egr valve and a total clean out of the intercooler,after doing just 22 miles on the new turbo low and behold,the engine started running. On and the usual pall of smoke was emitted from the exhaust.i am waiting for the mechanic to pick the car up and assess the latest episode,surely,someone,somewhere,must be answerable for the very poor design of these dci engines.i am a second owner of the vehicle and as far as i can make out it has been serviced by renault regularly before i got it and i have followed the service intervals albeit by a non renault garage.terry
