Do you have any codes? Check with code reader not all code set a check light. Do you have spark? Did you do the head gasket and was this a recent problem, is it not starting since doing the head gasket?

Those are communication codes so one of the computers is not talking for some reason. I would start by checking all system fuses. If one of the computers is not getting power it will cause this error.

Here is a guide and some diagrams of the fuse box (below) so you can do some testing.

Please check all system fuses with the key "on"

Please run this test and get back to us.

Cheers, Ken

All communication errors. Please check for power at each of the fuses and make sure the relays are working. If everything checks out check the power and grounds at the computers because something is not working or powering up. This car is diesel correct?
