SLS problem doing my head in

I can't see why to be a difference for nanocom if it's plugged into the cable or with the cable into the OBD port cos i see no logic and i've pluigged mine in so several times without any problem but if there are instructions about that better follow them and forget about this test even though it would have been a good test... but if you have access to testbook wait untill it's plugged in maybe you get a fault code and then you are on the good track

Xaymaca is correct. The cable should be connected to the Nanocom before plugging the obd2 plug in. This is because the earth contact is longer on the obd2 Plug than the other contacts, so the earth connects first before all other contacts which prevents voltage spikes from damaging the Nanocom.

Yes !!!!!!you can get sparks out of the nanocom plug if you plug it into the cable that is already connected to the OBD2 plug.

People that remove airbags and fit coils just can't man up they made a mistake and tell the truth that they would prefer the coils instead

The ride is just like chalk and cheese.
Airbags last quite a while, it's just a consumable that will need replacing at some time.

So I still haven't managed to do the exhaust valve test due to a flat battery from repeated start stops. I was charging the battery (while it was still connected - I know bad form) and I was measuring the volts it was putting into the battery.
I noticed, with key out and all doors closed, that it was dropping then going back up, then repeated. I could hear a clicking when it happened.
It was the exhaust valve cutting in and out? Not sure why it would have been doing that?

the exhaust valve alone would not affect anything as long as the air supply valves are closed... that releveling thing with ignition off was discussed fe w times i think on this forum too and there's no final conclusion on it...some of them are doing it some dont but it's not normal behaviour cos the system was built as to inflate bags only with engine running(except when SLS fob is used), IMO it can be a quite common ECU missbehaviour or the ECU gets a false engine speed signal somehow
