disclosure: I work as a professional diesel mechanic for a midwestern chain of shops. old diesel cars are literally the worst. I wholly endorse anything that will turn a 1986 Mercedes E class from a smog belching iron yacht into a functioning member of polite society. the price quoted here is a steal. take it. If i were hired to make an old diesel car come up to modern emissions specifications, it would easily be three to five times the cost. Im looking at ripping the engine apart, machining new entry points for sensors, buying a new ECU, finding a place for urea tanks and pumps, and retrofitting a nox scrubber somewhere not to mention the labor charge. the engine will run hotter, so ill need a new radiator or intercooler too. it also has to be retrofitted with a limp or purge mode for when the vehicle runs out of urea or is due for regular service to prevent violating emissions regulations.
