Bosch MG1CS011

New AT Protocol!

Dear Users,

It is our personal flasher's turn to welcome the VAG group's most widespread engine! We are very proud to announce that the Bosch MG1CS011 ECU (1.5 TSI, TFSI, TGI) is now supported on the end-user tool: the One.

This is a golden commercial opportunity to sell your remote tunes to thousands of Golf, A3, Leon, or Formentor owners!

🔄 The Workflow: For your customer to use their One through the diagnostic port, an initial unlock is required:
• Mail-in Unlock: The ECU must first be sent to our facility for a highly secure unlock.
• OBD on the One: Once returned, the ECU is ready! Your customer can now flash the solution directly from home via the OBD port with their One.

⚠️ IMPORTANT TECHNICAL INFORMATION ⚠️
• The protocol has been specifically adapted for the SPC5777M variant.
• Application blocks have been added to the readout.
• Crucial consequence: Older readouts are therefore no longer compatible with this protocol. Please ensure you take fresh readouts!

Supported Highlights (1.5L engines):
• Audi: A1, A3, A4, A5, Q2, Q3
• Volkswagen: Golf, Polo, Passat, Tiguan, T-Roc, Arteon, Taigo, Caddy...
• Seat / Cupra: Ibiza, Leon, Arona, Ateca, Formentor, Tarraco
• Skoda: Fabia, Octavia, Superb, Kamiq, Karoq, Kodiaq
• Ford: Tourneo Connect
