Can lambda connection issues

The map is wrong again.  CAN 2 should be off - or at least it shouldnt have a CAN Lambda assigned to a channel.

CAN 1 has 2 channels set up with CAN lambda, you can only have 1.

If still no joy, the next thing I would try is stepping through the different bit rates and trying the find devices thing each time - just in case bit rate was changed somehow in one of your earlier connection attempts.

Update to the latest firmware and then have a look at the runtimes screen CAN tab and tell me if there are now errors showing on CAN 2.

The map that you attached yesterday still shows old firmware.  Did you attach some old map, or has it not been updated?

Not impossible I guess, but all CAN ports and the CAN lambda is tested before shipping.  You cant get it to connect to either CAN port and its highly unlikely both CAN ports would have failed at the same time so I would probably rule that out.  So it could potentially be a faulty CAN lambda but again pretty low chance since they are burnt in and tested before shipping.  Where about's are you in the world?

Please post a copy of your tune and a PC log.  Also post any error messages that come up when you press F12 and then go to the CAN tab.  How have you wired in your CAN Lambda?  Are there any other devices on the CAN bus besides the CAN Lambda?
