Electric Fan DDE 3.0
The DDE control unit activates the electric fan by means of a square-wave signal with duty factors (= variable pulse width) between 5 and 90 % and thus controls variable speeds of the electric fan. The electric fan features its own positive and ground supply.
Troubleshooting
The activation function is monitored for short-circuit and open circuit but not the fan motor itself. Fault code 52 "electric fan" is stored if a defect occurs.
Consequence: Engine temperature increases
The fault code entry "electric fan, short to ground" may be caused by a mechanically blocked fan motor (in winter by frozen condensation water).

S blatnikom si niesom isty, tiez som ho uz menil ale nepametam si presne ako bol uchyteny.
Blatnik ale mal dva precnievajuce profily ktorymi sa uchycoval o kasnu, jeden v prednej casti pri svetle a druhy v zadnej casti dole pod smerovkou.
Teraz si vsak niesom isty kde bola matka na plech ktora je na obrazku, ale podla toho ako tam je nakreslena tak asi pojde na profily trciace z blatniku a potom skrz nejaky uchyt na kasni prechadza srob ktorym sa blatnik uchyti.
