525:. It was sold in vehicles from 1974 to 1991. The OM617 is considered to be one of the most reliable engines ever produced with engines often reaching over 1,000,000 km (620,000 mi) without being rebuilt and is one of the key reasons for Mercedes' popularity in North America in the 1980s, as it was powerful and reliable compared to other automotive diesels of the time. It is also a very popular choice for the use of alternative fuels, mainly straight or waste

laws in Europe by changing the bore to 90.9 mm (3.58 in). September 1979 saw a new camshaft with greater valve lift let air and exhaust gases have less resistance. Power output rose to 88 PS (65 kW; 87 hp). Torque remained at 172 Nâ‹…m (127 lbâ‹…ft) @ 2400 rpm. In
November 1980 the MW style injection pump was replaced with the M type for non-North American engines. Engines were equipped with
700:; sodium filled valve stems and a stronger nitride-hardened crankshaft. Also an uprated oil pump with separate chain drive was fitted as the turbocharger lubrication required higher flow. Bosch MW injection pumps were calibrated for greater fuel output and fitted with an ALDA device which prevented overfueling until the turbocharger had begun to provide boost pressure. Pencil glow plugs were provided on all OM617A engines.

The series-production turbocharged OM 617 A was fitted with a fixed-turbine-geometry wastegate turbocharger developed by Garret. It has a compressor efficiency of <74 per cent and a pressure ratio of ca. 3.0, delivering a corrected airflow of up to 200 g·s. Its maximum turbine speed
