2018 Beetle Coast -Stabilization Control (ESC) & Angle Sensor Help
Posted: Mon Jan 13, 2025 12:22 pm
Hi,
I own a 2018 Beetle Coast and am experiencing some fault code issues.
Now my Car does not want to crank Start. It dies instantly.
Here’s what happened: The car initially had a low battery issue (the battery was bad), but I didn’t have a replacement at the time. Instead, I charged it temporarily until I could get a new one. During this period, my windows would automatically lower every time the battery was reconnected.
Unfortunately, I think I made a mistake while trying to resolve the issue. To keep the windows up (since it had been raining a lot), I turned on the ACC (accessory mode) without starting the engine to raise the windows and disconnected the battery while ACC was on. Eventually, I replaced the old battery with a new one, but now I’m getting a persistent fault code for Stabilization Control (ESC) on the dashboard.
Also even with the new battery installed, the window with the door closed does not automatically go up like before even when you lock it.
My scanner is detecting the following faults:
01826: Steering Angle Sensor, Voltage Supply Terminal 30
03803: Steering Angle Sensor, Power-Assisted Steering
Additionally, I’m receiving a constant LOW OIL alert on the dashboard. I’ve replaced the bottom pan oil sensor, but the alert persists.
I’ve attempted to reset these faults using my X431 car scanner, but I haven’t had any success.
