Issue:

I’m experiencing a problem with my Beetle it's Dead & Wont respond . Here’s a summary of the symptoms:
Not Key Ignition, Its a push to start..


- Push to Start/Stop Button Dead – No response, completely dead.
- FOB Remote Control – Works fine; locks and unlocks doors.
- Dashboard Display – Only shows door/hood/rear alerts when open and no other symbols or indicators.
- Odometer Toggle – Displays mileage works.
- Hazard Lights – Functional.
- Radio/Display – Completely dead.
- High Beams – Work temporarily holding the toggle.
- Steering Lock Immobilizer – Was Removed for pushing and maneuvering the car but remains connected and tied off to the side.
- Fuses – Checked all fuses individually in both the engine bay and interior fuse boxes—none Blown/ Burnt found.
- Battery – New and fully charged.
- OBD Access – Unable to use a scan tool since I can’t turn on Power ACC to enable access because the push to start button is dead.

Its Not a Mechanical problem, It's a an electrical issue
Is there a hidden fuse or component burnt?

Unable to find Service manuals, Wiring schematics

Looking for advice on troubleshooting and resolving this issue. Any suggestions would be appreciated!

disconnect any aftermarket electronics, and check all fuses... start withthis and get back if it doesn't help

Try pulling and cleaning the contacts in the start/stop button. They are known to cause issues. There are several 'how-to' instructions and videos online.

Thank you! It turned out the push button was defective.

However, I’m now facing other issues with the Stabilization Control (ESC).

After installing the new battery, the car dies instantly. The windows don’t roll up fully, and additional faults keep appearing.

I’m also getting a constant OIL LEVEL alert on the dash, even after replacing the oil sensor.

My scanner is showing these faults:

01826: Steering Angle Sensor, Voltage Supply Terminal 30
03803: Steering Angle Sensor, Power-Assisted Steering

Any advice would be greatly appreciated!

For the oil level alert, it's usually the oil level sensor in the pan, hood open sensor (look it up and you'll see why ) and/or the wiring and connection to each.

The steering angle errors could be the steering wheel 'clock spring' inside the steering column. VW/Audi had a lot of issues with those across several models from 2010 onwards. I had similar issues with an A4. Not sure if the Beetles are in that mix.

Were any of these issues present prior to messing with the steering column and replacing the start switch? What type of scanner are you using (Ross Tech, OBDEleven, etc.)? Changing batteries alone on some VAG cars can create problems by themself. Have you tried clearing the fault codes to see if the errors and warnings return?
