I know they go bad. Any way to test? MiL's car died on Christmas.

Default It happens, but it's probably not the number one cause of no spark

A defective Hall effect sensor (G40) or engine speed sensor (G28, I think) is more likely. Check trouble codes.

Primary and secondary resistance of coils is easily measured. Got a Bentley?

Well, the timing belt broke, so no spark trigger. Sad, the replacement TB lasted only 70k.

Default Soft codes can be cleared by disconnecting the battery for 30 minutes

Hard codes have to be cleared with a VAG-com or VW scan tool.

You have an OBD port, not 4-prong?
