The vehicle runs on 6 wheels. The Trucks 3.5–12 t (Class N2) series covers 1532 models. Rated output within it ranges from 44 to 415 kW; the 518 CDI sits in the lower part of that range with 135 kW. Its immediate neighbours are the Atego 918L - 97023 / 4220 below it with 130 kW and the ATEGO 1224LNR/42 above it with 137 kW. Unladen weight within it ranges from 1,660 to 41,500 kg; here the 518 CDI sits at the bottom of that range with 4,750 kg. 8330 Mercedes Benz models across 126 series are on record.

The Düsseldorfer – Mercedes T2 and what the numbers mean: range 508 D to 813 D, four-cylinder OM 314 diesel, collective page of the N2 truck class from 3.5 to 12 tonnes

Anyone looking for a 508 D or 608 D is looking for the T2 — called "Düdo" by drivers and collectors, after the Düsseldorf plant where it was built from 1967 to 1991. The series ran until 1996, making it one of the longest-produced commercial vehicles in its class.

The type designation is arithmetic: the first digit gives the permissible gross weight in tonnes, the following ones the engine output in metric horsepower. A 508 D is rated at 5 tonnes and around 80 hp, a 608 D with the same engine at 6 tonnes. The "D" stands for diesel. Technically, then, less separates them than the numbers suggest — the 608 D is essentially a more highly rated 508 D.

Under the bonnet of most of these vehicles sits the OM 314: a four-cylinder inline engine of 3,758 cc with direct injection, rated at 80 or 85 hp depending on version. It was the most popular choice in the first T2 generation and also appears in the O 309 bus. Anyone hunting for parts still benefits: an engine used across several series stays supplied longer than a one-off.

In 1986 an entirely new second generation arrived, built until 1996 and delivered mainly with diesel engines. When buying used it is therefore worth checking the year: a complete redesign lies between the first and second generation, even though both go by T2.

Register entries in this class come largely from official registration data. They are reliable on dimensions and weights — equipment details of individual vehicles are naturally not part of it.

What to check before buying

  • Check the hour meter against the service records — a replaced instrument is the most common gap.
  • Compare the data plate and chassis number with the papers.
