Post revival.

Having similar issues. Cleaned my ETM, cleaned connectors and added Stabillant-22 on connectors for ECU and ETM. Thinking I may need to replace the connector to the ETM. How hard is this?
 
Nevermind. It appears the actual fix is to solder a new connector. But the clean and cover with Stabillant -22 may have done the trick. Drove it around and no issues yet.

So, I replaced the wiring connector by soldering the wires. Problem solved.

Edit: problem is still there.

The problem with replacing an "entire harness" is that a wiring harness will typically have many branches that go to various different locations in the car. During the manufacturing process, the harness is installed after the body has been welded up and painted, but before the various systems are installed, including hvac, interior lights, engine and transmission, instrument panel, interior panels, and seats. This means that the harness is buried in the structure of the car. You can see portions of the harness, including the plug connections, but much of it is not easily accessible. It is not so hard to repair a wire, or a bad connector. I had to replace a headlamp connector a few months ago, because the old one had become oxidized, and overheated. I think it took an hour.
My son pulled one off a p80 at the yard and replaced his with it.
