the Volvo V70, Volvo S70 and Volvo C70 the system was used until the end of model year 1998. 4.6 The Motronic 4.6 was used in Nissan Micra K11 from 2000 until 2003. Motronic 5.X 5.2 Motronic 5.2 was used in the BMW M44B19 engine. Compared to 1.7, Motronic 5.2 has OBD-II capability and uses a hot-wire MAF sensor in place of the flapper-door AFM. 5.2.1 Motronic 5.2.1 was used in Land Rover Discovery Series II and P38 Range Rovers that were built starting with late 1999. It was only used in cars equipped with V8 gasoline engines. This variant of the engine management system was adapted for off-road use. Unlike the Motronic system in BMW sedans, that uses a chassis accelerometer to differentiate between misfires and rough road, the Land Rover version used signal from ABS control unit to detect rough road conditions. This version of the system was integrated with body control module and anti-theft system. short list of ML-Motronic ML-Motronic appears in 1979. BMW equipped the E32 732i with the Bosch ML-Motronic. This was a L-Jetronic (now in digital technology) with digital ignition control in the same housing. Data was stored in EPROM. ML-Motronic and M-Motronic must be keep appart. There is ML3.2 and M3.2, these a two different things. short list of M-Motronic While the ML-Motronic is continuing and new ML-Motronic versions appers, Bosch launched the M-Motronic. There were many versions. While older versions were improved and further developed, new M-Motronic versions appear. So it makes no sense, to identify newer/older versions within the first counting numbers after the “M”. For example: M1.5, introduced by Opel in 1988 M1.5.2, 1991 M1.5.4, 1994 M1.5.5, 1997 The M2.3 und M2.3.2 (used by Audi/VW) appears long before 1997. So the M1.5.5 is much more developed than the M2.3.2. ML-Motronic and M-Motronic must be keep appart. There is ML3.2 and M3.2, these are two different things.
