Hi I have a Vectra B 2.0 TDI -1998. I have been trying to find out if this car used the OBD 1 or 2 system, and what is the best and cheapest scan tool I can get for it?

Can anyone help this chap?

Someone must know.

For once I havent got the faintest!

same here mate, whats an OBD?

I'm still in the land of the carburettor!

On Board Diagnostics?

Although Vauxhall put in the ALDL 16 pin connectors (next to the handbreak) they did not comply with the OBD2 standard. This means that the off the shelf scanners/fault code readers do not work with Vauxhall. There is one available at ukodb.co.uk at £265 but I have not seen any cheaper that work. From 2001 onwards for petrol and in your case, 2004 for deisel OBD2 standard is complied with. In the US this standard came out in 1996 (by law) so most manufacturers in Europe saw the writing on the wall and complied, unfortunalely not Vauxhall. Most of us enthusiasts short out pin 5 and 6, turn on the ignition and count the fault codes. As for scanning active sensors, the main dealers use Advanced Diagnostics Tech2 and I suspect that Sykes-Pecavant do a scanner for the professionls i.e quite expensive.
