Ive got a 2004 megane scenic 1.5 dci that has just come up with a rather random fault, When you driving at normal temp it come up with injection fault on the instrument panel when you get to around 3000 - 3500 rmp and it judders in a manner of speaking. So i took it to my local renault dealer to have the diagnostic plug in and they printed out the fault codes for me. Now when i asked them what the issue was they got very secretive i think and didnt want to tell me whats what, yhey just said id have to bring it back for the day for them to look at. Now when its not up to full temp it drives perfectly normal and also when it nuetral it revs cleanly all the way t maximum revs, No smoke or anything and you can here the turbo so i know its working fine

My main concern was it was either the high pressure pump on the turbo but they have confirmed it is neither of these, the print out comes up with fault code DF008 PEDAL POTENCIOMETER CIRCUIT RACK 1. And in the tech's handwriting it says Component blocked.

The second code reads DF053 RAIL PRESSURE REGULATION FUNCTION and again in the tech's own handwrititng it says at minimum limit.

Now when I asked about fixing it they didnt want to give me any more info just that i should bring it back to them.
Now i fully understand that they have to look after themselves and need to get work in but i didnt find them very helpful compared to other main dealers Ive used,
What i want to know is how do i go about sorting it myself rather than resorting to extorsionate prices etc etc. is there anyone out there that can help a fellow Passionforder. Cheers
