About Us

The Company T.W. Diesel, situated in Witbank, has all the equipment, specifications, jigs and test benches to do professional repairs to our SL’s tough, but nevertheless ageing, high pressure fuel injection pumps.

These BOSCH pumps are very robust and have run for more than 45 years and will continue to do so, unless they are ruthlessly manhandled or run without oil. Unfortunately they easily get blamed for all sorts of problems that are usually due to twiddling all the inviting adjustment screws and handles!

Rolf has been in this game with BOSCH since 1970 and qualified in the BOSCH environment here and overseas before opening T.W. Diesel in 1981. T.W. Diesel has even received awards for being the best BOSCH repair facility on the African Continent (the coveted Jetronic Continental Cup). T.W. Diesel's expertise stretches beyond our pump interests into complete engine recon and automotive electrical work as the pics show. A complete story on T.W. Diesel's activities goes beyond the scope of the SL Chatter, so feel free to browse the rest of the website to learn more.
