Throttle valve control unit -J338-: cleaning
  Note
t  If a new engine control unit -J623- has been fitted, the throttle control unit must be adapted. Adapting is only carried out with the new or previously cleaned throttle control unit, because if there is dirt/carbon at the top limit of the throttle, the adapting readings could be faulty.
t  Take care not to scratch the throttle valve housing when cleaning it.
–  Remove throttle valve module -J338- → Chapter.
   
–  Open the throttle by hand and lock with an appropriate tool, such as a plastic or wooden wedge -arrow-.
  WARNING
Acetone is highly flammable. Respect the accident prevention regulations and the safety indications when working with highly inflammable liquids. Do not use compressed air when cleaning the throttle valve. Wear safety goggles and protective clothing to avoid possible injury and skin contact.

–  Clean throttle valve housing, especially around the points -arrows- where the throttle valve closes, using commercially available acetone (DIN 53247) and a small brush.
–  Clean the throat of the throttle valve with a lint free cloth.
–  Wait for the acetone to evaporate completely and then fit the clean control unit.
–  Erase adaptive values, and adapt the engine control unit -J623- to the throttle control unit.
