Question

I cannot recall if the glow plug timing can be lengthened on the PD engine like it can be on the 1Z & ALH >? my cable is pre-PD(04)

If so is there anyone in the denver area with a vag-com-cam who knows how and could offer that to me>?

It can not be adapted via VCDS. It would need to be reflashed into the ECU software.

Is there still anyone in the denver area still doing tunes &/or flashes on my car so I can get the car tuned with glow plug timing increased also?

the issue is up in the mountains after being parked overnight the glow plugs just don't stay on quite long enough to give what I expect as a smooth cold start...

On a related side note for info, in the metro denver area, the scan gauge II shows static atmo pressure @ 11.2-12 psig, while at sea level it shows ~a pretty steady 14.5....and the issue of that ~11 psig static atmo number dropping even lower in the mountains can make cold starts in every diesel I have ever owned be entertaining, to say the least....

Adjusting in the ecu with the vag com cable to have the glow plugs cycle a just little longer related to altitude & cold temps has always been one of the first mods I made to every 1Z & ALH I have ever owned/driven up here to make these cars crank/start ups much smoother in the cold with less coughing & missing once the engine catches up there...
