OBC was an option. It can be retrofitted fairly easily and cheaply if you have reasonable DIY skills. Check out RennTech.org for instructions, or drop me an email via my profile page.

ah OK

thanks for replying

I can do without it tbh unless its an inexensive procedure?

cheers

The cheapest way is to use a rocker switch in one of the spare slots in the "horseshoe". It costs about £30 in parts, and an hour and a half to do. It then needs activating by someone with a Porsche tester (a 5 minute job).

My very basic '99 c4 had this stuff. It's just on one of the two lower stalks (left one i think)
