BMW 520, Diesel, 360,000 km from 1999.
Old lady very smelly at the exhaust and now slow.
We carried out the treatment for internal cleaning of the engine with hydrogen #Hydromaverich #Ecleaner, we cleaned the entire engine up to the exhaust.
Now he no longer smokes and the smell has significantly reduced, plus the ride is smoother and quicker.😎 Very smoky BMW 520, solved with Hydromaverich Ecleaner hydrogen decarbonisation
