help me please guys. My car drove to work perfectly this morning but when I left to come home it felt like it took longer to start and like it had a misfire. I thought it was a N injector as I have done a couple of them now. After driving for a few mins it felt better. I got nearly home and popped into the shop and when I came out it took forever to start and had no go in it whatsoever and was running really badly. I then took the uncomfortable journey home at 5 mph (normally a w min trip from the shop, it took me half an hour). When I got home I plugged my cheep obd reader and it threw up P000a then changed to P0016 camshaft position sensor. Is this an easy fix or is the car now dead? It is a 2007 Audi A3 1.8 tfsi.
