| The garage plugged in a diagnostic tool to my Astra today to see what was going on with the alarm system. It´s a ´99 1.8 CDX Astra Estate.
 As far as I could understand the nice German mechanic, his machine required the ECU code unique to the car before he could ´get in´ to the system and start checking stuff.
 This apparently comes on a card...which I don´t have in the car document wallet. Grrr.
 Now, is there a ´default´ code that will bypass this problem, like a master key, and get into the system? Or is there another way round it?
 Any ideas very much appreciated.
 Thanks,
 Barchettaman

                    | I guess this isn't a Vx/Opel dealer.  The ECU code is available from any Vx dealer.  Every new car is supplied with a 'Car pass' which contains the ECU Code, radio code, key number etc.  A replacement pass can be obtained from Vauxhall - costs a tenner or so.  The ECU code is needed, for example, to programme new keys to the system, or download new software, but I didn't think it was needed just for a diagnostic code read.  Ceratinly wasn't on my old vectra ('96), but maybe things have changed.  Whatever, the code is easily available.

                    | Cheers John. I have rung the original dealership who helpfully had the codes on file. Nice people too - CD Bramhall in Wolverhampton (altho´ they´re called something different now). Haven´t heard the ´black countrei´ accent in a while...
