# MQB RVC Mid to (7N0) PQ Conversion
**Introduction**
![[MQB RVC Mid.png]]
I first theorised this conversion after noticing the MQB and PQ **RVC Mid** modules were both Panasonic-built and nearly identical aside from the CAN transceiver. To test the idea, I bit the bullet and paid **$400** for a genuine PQ unit online.
To my surprise, the so-called "7N0" had signs of prior soldering and a plain white label instead of the reflective OEM style. Proof I wasn’t the first one down this path! But it did confirm the theory: the difference really is in the CAN physical layer and firmware.
- **MQB Native Units**
Found everywhere from **Audi A7** and **Porsche Panamera** through to the **Lamborghini Huracan**.
They also have provision for a **second video input** (front camera / TV tuner), have not got this working on PQ yet.
Audi sourced modules are common at wreckers and go for around **$40–100**.
- **PQ 7N0 RVC Mid**
Only fitted for about a single model year in **Tiguan** and **CC**.
Scarcity drives prices up (**$300–500+**).
Functionally, they’re MQB units with a **fault-tolerant CAN transceiver**.
Because of this, MQB to PQ conversion is the smarter path.
**Prerequisites**
- **MQB RVC Mid Module:** See the table below for compatible part numbers.
- **Flash Tool:** Software capable of writing .odx files (e.g., ODIS).
- **Soldering Equipment:** Required for component modification.
- **Electronics Components:**
- 2 x DTA144EUAT106 PNP Transistors (SOT-323)
- 1 x AMIS41682CANM1RG Fault-Tolerant CAN Transceiver
**Compatible MQB RVC Mid Modules**: Note only 5Q0 has been tested

**Conversion Instructions**
1. **Bench Setup:** Connect the module standalone (no gateway).
2. **Flash:** Using a compatible flash tool, upload the file `FL_5Q0907441__0130_to_7N0907441B.odx` to the module.
3. **CAN Communication Loss:** The module will temporarily lose CAN connectivity.
4. **Component Modification:**
- Desolder the MQB CAN transceiver and marked resistors (see images).
- Install the **AMIS41682 fault-tolerant CAN transceiver**.
- Fit the two **DTA144EUAT106 PNP transistors**.
5. Wire into the PQ CAN network.
6. **Parameter Upload:** Enter EOL mode, upload vehicle-specific parameter set.
7. **Calibration/Update:** Run calibration or import EEPROM data to finalise operation.
