Anyone know the difference in the Mechatronics unit fitted as part of the voluntary recall of 7 speed DSG units, in my Jetta yesterday and that of the original unit fitted in 2009?
My understanding of the problem with the units is "electrolysis of the oil" (becoming conductive?) in the unit causing the computer circuit to short out . Cause of this being moisture absorbtion ?, corrosion of parts ?or breakdown of the surface of components (corrosion) of the material of the housing ? or any one or all of these?
I'd be very interested to hear what has been done; assuming VW aren't just replacing the original ones unchanged.
New materials? Different oil?
Also does this DSG, the dry clutch, one run considerably hotter than its oil bathed cousins?
Thanks in anticipation.................................
