hi guys had a diagnoses on my td5 03 plate. as i had the 3 amiego lights on. come up with shuttle valve electrical fault. i have the link on this site how to fix that. now i had engine managment read. this is the faults it came up with. high speed crank synchronization lost (fault) next noisy crank signal detected. (fault) road speed missing (fault) now can any one explain what s happening with them and were they are on vehicle if i have to change them.

why couldnt the bloke that tested it explain?

hi because i borrowed a snap on off my m8 and decided to go through the lot so i just wrote down what was on the display.
