Hi guys. Well the vans been running a bit rough and a rac friend of mine has used his unit to find these errors. The egr one I can understand but the P0683 seems a bit vague. Any ideas?

the p0103 is just a faulty light earth.

P0683 = Glow Plug Control Module to PCM Communication Circuit.

It could be a break or poor connection in the wiring between the glowplug control unit and the engine management ECU.

the p0103 is just a faulty light earth.

P0103 = Mass or Volume Air Flow Circuit High Input.
