Hi I have a 2011 c5 1.6 e-hdi and wanted to fit one of those reversing cam,s so I looked on ebay and found many to choose from and at anything from 18 quid to 25 quid so I got one and it took me about an hour to fit and to this day is still working very well. Have a look mate. There are the 100 quid to 200quid one,s but they don,t in my mind do any better.
