Hi John,
No, unfortunately, you can't, for many reasons.
What's your schedule like on Monday? I'll be travelling down to WOM and may be able to stop at yours and fit a loan ECU to your TDI such that you can at least move it.
Regrettably, I've had no time to fix your ECU - getting the first batch of Colour DIS clusters sorted has had to be my priority, as lots of people are waiting for them.
Cheers,
Tom
