Wussy TDI thinks it's too cold to start

[PassatB6]

The fuse thing sounds suspicious. Check tabs on fuse holders to see if they are tight enough to hold the fuses properly. Apparently this can cause the PRNDS flashing and no starting. There is a case of this on the TDI club site. Good luck with it.

cheers for that passatb6
it does sound like a computer problem
previously to me it seemed liek the cars were not priming when unlocked and weren't getting enough fuel to start

I found this one which best describes the problem

I'll let you know how I go

strange findings

the ECU was not sitting in its cradle and is scratched, evidently it has been removed before.

Left the car at Mike Webers to do overnight cold start test, both mornings it started no problem. This damn thing... had the ECU contacts and earth point cleaned and hopefully it will be ok.

Even went as far as removing the ECU and putting it in the fridge, what a PITA to chase an intermittent problem
