    White smoke is coming from the exhaust of my Toyota LandCruiser Prado diesel

    Toyota Toyota Advice Toyota Prado Toyota Prado Advice Toyota Landcruiser Prado 2016

    My 2016 Toyota LandCruiser Prado TX (diesel) produces a lot of white smoke from the exhaust, which stops after a while. It will then repeat the same behaviour. I have changed the diesel filter and it still does the same. Kindly advise.

    White exhaust smoke in a diesel engine is usually the result of a fuel system problem. Possible causes are dirty, worn or leaking fuel-injectors, but a modern common-rail diesel fuel system is pretty complex, so a scan of the vehicle might be a good idea too.

    Some owners of these modern diesels have been reporting very short injector lifespan, although some workshops seem to get good results with ultra-sonic injector cleaning. Even then, the problem can recur, and some mechanics reckon brand-new injectors are the only way to go.

    Don’t rule out a problem with the engine’s internal seals, the turbocharger and the DPF system, either, as these can all contribute to smoke of various colours at various times.
