My first post and unlucky it has to be one with a problem about my CVT. Gearbox type is "GHW"...does this mean the the multitronic slush box? http://www.audi-sport.net/vb/images/smilies/bye.gif
I brought a 2004 A4 1.8T (non S line) and everything is fine with the car apart from the CVT "speed sensor". My mech tells me this part is not like the old B5 but actually encased inside the "automatic gearbox control unit" which lives inside the gearbox.
I understand the unit is submerged in ATF oil but how does it read the speed from the gearbox? Does the contorl unit have any mechanical parts attached to the outside that bad ATF oil could affect it?
I'm trying to weigh out the differences in buying a new control unit to trying my luck by changing the ATF oil. I read online that it maybe possible to fix this error code by just changeing the ATF oil. However, ATF oil isnt cheap at 86 pounds for 8lts required but could save me a small fortune. New control unit is 400 pounds + 86 ATF oil + 100 labour charges.
Does my gearbox really take 7.7lts or ATF.
Billion thanks!
