It sits in the factory ECU location, takes the factory connectors, runs the factory electronic throttle on its own and adds an onboard MAP sensor. Link has confirmed a short list of cars and engine codes, shown below; other 1.8T models are likely to fit but are not confirmed.\u003c\/p\u003e\u003ch3\u003eFits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAudi TT with the AJQ engine, 1999-2002\u003c\/li\u003e\n\u003cli\u003eVolkswagen Beetle with the AWU engine, 2005\u003c\/li\u003e\n\u003cli\u003eVolkswagen Passat 1.8T, 2000\u003c\/li\u003e\n\u003cli\u003eVolkswagen Golf with the AUM engine, 2001\u003c\/li\u003e\n\u003cli\u003eManual transmission only\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBefore you order\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManual transmission only.\u003c\/li\u003e\n\u003cli\u003eYour factory ECU must have two connectors with 121 pins in total.\u003c\/li\u003e\n\u003cli\u003eThe engine must be the 1.8T, and the drivetrain front-wheel drive or Haldex-based 4WD.\u003c\/li\u003e\n\u003cli\u003eOnly the cars and engine codes under Fits are confirmed by Link.
