TMM-- Thanks that was what I was afraid of. I was hoping it might be a sensor or a wire issue. So is this a definate or is there anything I need to rule out first?
I finally bought a low profile hi lift jack today, Am I understanding correctly I need to drop the engine if this "bank 2"vario has gone kaput?
Anyone else please chime in with a second opinion/option, please!
Back in the day I could drop a VW bus engine in 12 minutes flat, somehow I am thinking this will not be so simple, I am sure...
