Hi there. At the and i and up by changing the whole unit. I have found used switch, same spec, but made for 4 cylinder cars, part number 61319123041. What i had before in my car was the 61319123049, same spec unit but for 6 cylinder cars. They coded the old new switch to the car, and now everything is fine, all working good. Visually what i found is that now the symbol in red circle is missing, beside this all is ok.
im giving this info to anyone that and up changing the unit, you can use the same unit from 4 cylinder cars also, no matter it is another number. Cheers.
