Righty ... Anyone with experience of this issue who can point in the right direction....
Mk7 diesel transit, 2.4 l ... starts on the key and runs if key kept in the start position, but cuts out immediately on release. (People have suggested ignition switch) .... BUT
If I rev it before releasing the switch the van runs normally. Which is why I don't suspect the ignition switch. Could be wrong, but would like done reasoning.
Happens cold or warm.
Have tried sprinkling sawdust around obviously. Also I've put a bag of rice in the glove box overnight.
