I have a 1.6 tdci Gina showing the following faults

P0014 - B camshaft position - timing over advanced or system performance

P0015 - B camshaft - Timing over retarded

I am wondering if anyone know what is making my car show these faults. 

Cant find anything on these fault. Any help would be great. 

if this is the 2007 car shown in your car details section then it will have twin camshaft engine. I do not know if each camshaft has it's own camshaft position sensor on it . The first camshaft is driven by a rubber (toothed) timing belt from the crankshaft. the 2nd camshaft is driven by a chain from the first camshaft. I am wondering if there is a load of slack on the chain and a possible chain tensioner problem which means the relative position of the 2nd camshaft keeps varying.  It's a total guess on my part really. (but what I have told you about how the camshafts are driven is definitely correct, not a guess).

Does it put the engine management light on?  does the car go into limp mode?  I assume one of these is Yes to have caused you to check the codes.

How did you get those codes?  Generic OBD scanner?

The DV6 engine has fixed timing and only one cam sensor.
