I heard a bang like a ran over something on a dirt road. Kept driving fine. Got to my destination OK. But when I went to leave, the car started fine, idled fine, but NO throttle response and EPC light on. I had to abandon it in the middle of the forest. I ran codes with an OBD reader. It's a 2004 Beetle, standard trans. 2 liter. Not a turbo.
P0038 HO2S Heated oxygen sensor High Voltage.
P0141 HO2S Heated oxygen sensor Circuit Malfunction
P2128 TP Accelerator Position Sensor, Switch E - High input
P2123 TP Throttle Position Sensor switch D - High input
P0221 TP Accelerator Position Sensor APP Circuit Performance
I looked under the car and found the wire to the O2 sensor on the exhaust pipe had been pulled down in a dangling U shape that was dragging on the ground. the wires seemed to be OK and it was all still connected.
I have heard that this wire can short and fry the ECU.
I need to buy the parts and head up to the forest and fix it, so need to know what to get first.

Where you read this can fry ECU?
You are going to have a hard time in forest.
ECU is not plug and play! Needs to be programed in order to work.
Also dealer only unless you have VCDS and a way to get SKC/PIN for immobilizer.
Shorted O2 wires can fry ECU and loose throttle. Sure looks like that's the problem based on the codes.
Good Luck
