well i know us vaux lads can get Vauxhalls own EPC (Electronic Parts Catalogue) that the delers thamselves use to find parts and numbers which has all the blow out diagrams of every part of every car vauxhall have made for the past 20 years and theres also vauxhalls TIS which covers there mantanance bays which covers diagnosis labour times and service info. i am shore renault have a simler system you just need to know some one that can get a copy. (
for the vaux one)
but as the renault modding sene is not very big its prob not been worth some one coppying these things but you never know, just get very frendley with the workshop maneger and he might give you a copy.
can come in handy when refitting things because you can see what goes were and also when ordering things because you just ring up and say can i have 3 GMVX02495032010 and thats it no messing. also good to see what bits off other cars fit on other things and so on and so forth
