Urgent need of AL4 Autobox Lexia genius, North Essex!

[PeteC8]

I have just replaced the 2 pressure solenoids in the AL4 box on my 2004 C8 2.0HDi (90000miles).

My problem is the original ones were the factory fitted 50hz type, the new ones are the updated 100hz ones, so I need someone with a Lexia who can update the ECU firmware to the later version 02 or 03 in order to recognise the change.

Car is pretty immobile unfortunately. I have tried messaging a chap in Colchester who is on the forum as a contact, but guess he has been quiet on here since May.

Any suggestions welcomed, thanks Pete
