Hi all, still struggling with an intermittent no crank/start issue. Can be fine for a few day's then suddenly return. Once it starts it runs fine. Basically not turning over, i hear the solenoid engage but that's it.

So far, replaced battery, starter and solenoid and main earth strap from engine to chassis. No error's showing.

Any thoughts? Thanks

I can't remember what's already been cover in other thread(s?) but as it's intermittent it could be caused by so much.

Do you have KESSY keyless door entry with keyless ignition? No crank makes me think of perhaps ignition switch or immobiliser issue or signal blockage (some charm hanging on or around the area. KESSY intermittent issue with remote key. Proximity keys, gawd bless their cotton socks.

Has ignition switch been checked? What type of ignition switch is it.

Have you got two remotes sniffing after one vehicle, one in your pocket or handbag another in a kitchen drawer within range - have you tried swapping keys/remotes.

If one of these KESSY things Is the key not in use kept in a tin box? Have you checked or changed the remote batteries.

There really needs to be more details of when the no-crank happens, the circumstances, where, what's being used, what's happening, just happened, when (time of day, engine hot/cold warm, first start of the day, etc.). need to see if there's a pattern.

As I remember it Dealership/garage can't find it, no error codes, a possibly earthing issue investigated from change of starter(?) or engine earth strap, battery, stater motor and solenoid and engine earth strap changed.

Then of course there's the potential for the wunderbar complex and intertwined VW computer systems and programs to have issues.

I think we covered things like fuse board or it connections.

Intermittent no crank, difficult enough with the car in front of someone but over a forum . . . if information is given in an extracting teeth fashion too the car could be replaced before possibly suggestions could be sensibly made (by those brighter than me).

It very much sounds like no cranking because the switch is an issue and the shifter is not properly in P or N. Connection not right. Throwing parts at the car like it is a game of bingo is not financially Simply Clever.
