Sorry if this double posts, but it's taken over a day for my old one to be approved, trying again.

Hello,

I’m new here, and new to working on beetles/VW.

Little bit of what happened before doomsday. So it’s my girlfriends car, and we live in TN and it’s getting cold fast. Her blender doors were bad and I had to remove the HVAC to fix them. Good news the heat and ac works now! Bad news, the car’s tachometer no longer works, and it won’t shift above 3rd ger. I have a flashing red oil light, flashing red brake light, solid yellow ABS light, and Airbag Light.

I’ve taken the dash back apart and checked for obvious torn/scraped/exposed/cut wires and I didn’t notice anything, checked all fuses, sanded the grounds under the dash and the two in the ECU/TCU area. I’m at a complete loss, the car did not have any of these problems before. Tested Amp draw while key is out using multimeter with negative terminal disconnected, came out to be around 480mAh.

Could this possibly be a bad ECU?
