does anybody know where i can find a list of ecu login codes for specialist functions such as switching on/off the egr valve functionality..

there is also a login code for locking the ignition timing so you can set the base timing of the distributor with a timing light but i can't for the life of me find the code anywhere

I have successfully used 12233 on non PD Octavia's (and IIRC a VW Transporter)

11463 works on Octavia vRS's (MKI) as well as MKII Octavia's (not used it on a MKII personally though.

thanks for those, they are both bosch ecu's though
