Audi 2.0 TFSI Simos 18 ECU Bench Programming & DTC Review
This workshop record shows an Audi / VAG 2.0-litre TFSI petrol engine ECU connected to a direct bench-programming fixture. The recorded programming interface lists the Continental Simos 18.1 / 18.2 protocol family; the precise fitted ECU revision requires label or diagnostic identification.
The customer-described request involved NOx, EGR, catalytic-converter (CAT) monitoring and permanent DTC / P-code deletion or removal. The photographs and short video document the hardware connection and programming session—not which fault codes were modified, any emissions test outcome, or legality for road use.

Bench-programming connections
Wide workshop view of the opened petrol ECU, direct probing connections, power and signal wiring, and controlled access to the board.
Close-up of the circuit board and test fixture
Detailed view of the ECU, probe needles and connected wiring. The exact ECU identification should be checked from its part numbers and supported diagnostic data.

Workshop assessment
Continental Simos 18.1 / 18.2 ECU software and fault-code assessment
The ECU-control-system family is used in selected VAG petrol applications. Simos 18.1 and Simos 18.2 are not assumed interchangeable: software access, checksums, calibration and fault-code interpretation depend on exact hardware/software identification and the vehicle's configuration.
NOx, EGR, catalytic-converter monitoring and permanent diagnostic trouble-code (P-code) concerns may appear in customer enquiries. Our documentation distinguishes a customer's requested software change from verified findings: no individual P-code list, calibration values, or post-repair test results were supplied for this case study.
For roadgoing vehicles, our related work includes vehicle fault-code diagnostics, ECU software flashing and programming, VW, Audi, SEAT and Škoda module programming and DTC assessment information.
Emissions compliance & roadworthiness
Important distinction for UK road vehicles
This is a factual record of an ECU bench-programming enquiry, not evidence of road-legal emissions-system removal. Removing or disabling manufacturer emissions controls, or suppressing their fault monitoring, can make a vehicle unlawful for public-road use. The MOT checks original emissions equipment, including catalytic converters and EGR components where applicable.
For road-registered vehicles, faults should be diagnosed and repaired with applicable emissions equipment and monitoring functioning correctly. Any competition or non-road project must be assessed against the specific applicable requirements; no off-road-only status is claimed for the photographed ECU.
See the DVSA MOT inspection manual, Section 8 for the relevant inspection standards.
