PEH,tell me more about the SD/SDL's bypass/full flow filtering capability. I was not aware that there is more than the one full flow filter. Where is the extra by-pass filter located?
Lube, thanks for the input. I have found a great web site called "Fred's TDI", and the users are very familiar with the by-pass filter and its pro's and con's. Sounds like a good idea if you want to really get extended life from oil and motor.
