Service Lights Reset - pin 7, 19, or both???
 

I just went to the dealer to get an oil change and they did not reset the service indicator lights because I just got and oil change and filter instead of an OIL SERVICE. Kind of lame. So i've read you can reset them yourself by grounding the pin connector 7 or 19 or both, but I'm reading differnt things, so which is it??? I have a 98 328is. I don't want to screw up any electrical stuff, so I'd like to be certain before doing it. If someone has a good website with pictures and instructions, I'd appreciate it. Thanks!!!!

If you dont want to screw it up, but a reset tool. I too have heard that it is possible to reset the lights by grounding out pins, however I have also sold brand new ECU's to some people (big bucks) because of voltage spikes.
