Module 65 - VAG MED17, EDC17 CAN TP2.0, K Line

Caption:

• RD: Read
• WR: Write
• CK: Checksum correction

Supported ECU

• EDC17U01/U05/CP04/CP14 K-Line [VR/WR/CK]
  
• ME17/MED17/EDC17 CAN TP2.0 [VR/WR/CK]

A new package 65 “VAG MED17/EDC17 CAN TP2.0/K-Line” has been added, designed to work with Bosch ME(D)17/EDC17 ECUs that operate on the CAN TP2.0/K-Line protocol. It supports writing modified firmware via the diagnostic port, checksum verification, and correction. Supported ECUs include MED17.1/17.1.1, ME(D)17.5/17.5.1/17.5.2/17.5.5/17.5.6/17.5.20, EDC17U01/U05, EDC17CP04/14/20/24, excluding paired ECUs.

Explanations:

1. Only writing of firmware to ECUs with any TPROT is supported. Stock files are taken from the archive. Full software is written (just like in UDS blocks). Calibrations read by other tools via OBD are not suitable.
2. Reading is not available and won’t be added. ECUs with high TPROT cannot be read (and some with low TPROT as well). It’s not worth implementing.
3. I may add reading for ECUs that only have low TPROT. Separate modules for these may be included in the package.
4. Full reads from boot/BSL can be used without prior preparation, but please send such stock files to be added to the database.
5. When choosing software, ensure the exact match of the part number, just like with other VAGs, which ensures compatibility, while the software version indicates the software level. The software can be updated immediately.
6. After writing, clear errors using the button to avoid guessing why the “Check” light is on.

Features:

1. Read the explanations.
2. During writing, the fan may turn on, so connect a battery charger in advance (but not to laptops) or disconnect the fan connector if it’s accessible.
3. Writing is slower than UDS, so keep this in mind. The writing time is usually 5-10 minutes.
4. K-Line is only found in EDC17. If the ECU provides identifiers via K-Line, try starting the writing process through it. If the process stops when entering programming mode, the ECU is CAN-based. Use the “neighboring” module (note: Touaregs with the CASA engine can have either K-Line or CAN, so don’t be surprised).
5. ECUs are not afraid of connection interruptions, so you can turn off the ignition.
6. If additional equipment is installed in the vehicle connected to CAN (like LPG systems, radar detectors, trip computers), it may cause issues where even the identifiers won’t be shown. This equipment needs to be disconnected.

What is supported: This was primarily developed for 17.5 with high TPROT (for example, PASSAT CC, PASSAT B7 – 1.8/2.0 TSI engines), 17.5.2 (e.g., facelifted Tiguan with 180 hp, PASSAT), edc17cp14 – 2009-2010 Touaregs with CASA engines, etc. However, it also works with other ECUs. Note: 17.5.6 (North and South American markets), 2.0, 2.5 FSI engines have not been tested yet, but there shouldn’t be any issues. 17.1.1 – RS Q3 – similarly supported.
