Description

### Describe the car bug

## Summary

My vehicle is a 2019 Volkswagen Tiguan Allspace (Mexico) that is not automatically recognized by openpilot.

The vehicle works correctly after manually selecting:

**Volkswagen Tiguan 2018–2024**

This indicates that support already exists, but my ECU firmware versions are missing from the firmware database.

## Vehicle Information

- Vehicle: 2019 Volkswagen Tiguan Allspace
- Production: Mexico
- Platform: Volkswagen MQB
- VIN: WVGZZZ5NZKM16****
- Harness: Volkswagen J533
- Device: comma 4
- Fork tested: sunnypilot
- Manually selected platform: VOLKSWAGEN_TIGUAN_MK2

## Current behavior

Without Force Fingerprint:

- openpilot reports **Car Unrecognized**

After manually selecting:

**Volkswagen Tiguan 2018–2024**

everything works correctly:

- Steering works
- Lane centering works
- ACC works
- No more "Car Unrecognized"

## ECU Firmware extracted from rlog

```python
(Ecu.fwdCamera, 0x74f, None):
b'\xf1\x872Q0980653C \xf1\x891302'

(Ecu.fwdRadar, 0x757, None):
b'\xf1\x872Q0907572AC\xf1\x890401'

(Ecu.eps, 0x712, None):
b'\xf1\x875QM909144C \xf1\x891082\xf1\x82\x0521A60604A1'

(Ecu.srs, 0x715, None):
b'\xf1\x875Q0959655BR\xf1\x890403\xf1\x82\x1312110031333300314240013750379333423100'

(Ecu.transmission, 0x7e1, None):
b'\xf1\x870DL300013G \xf1\x892620'

(Ecu.engine, 0x7e0, None):
b'\xf1\x875NA907115E \xf1\x890007'
```

## Request

Could these firmware versions please be reviewed and added to

**CAR.VOLKSWAGEN_TIGUAN_MK2**

so the vehicle can be automatically recognized without manually forcing the fingerprint?

I can also provide:

- rlog.zst
- qlog.zst
- full Connect route
- additional CAN logs

if needed.

Thank you.

### Provide a route where the issue occurs

91998696732ba457/00000004--c333d4f896

### openpilot version

openpilot 0.11.1

### Additional info

## Additional information

The physical forward camera installed in the vehicle is:

2Q0 980 653 D

However, the ECU firmware identifier extracted from the vehicle reports:

2Q0980653C

This appears to be the firmware identifier returned over UDS after coding/SVM and matches the firmware extracted from the rlog.

The attached ZIP contains the corresponding `rlog.zst` for this route.

Research direction

Start by reading the Volkswagen Tiguan MK2 firmware entries and compare them with the ECU firmware identifiers reported here; use the provided route and attached rlog if verification is needed. Done means the valid fingerprints are associated with CAR.VOLKSWAGEN_TIGUAN_MK2 so this vehicle can be recognized without force fingerprinting.
