TDi Questions??? Ask Away!

505.01 is VW's special oil for the PD (pumpe Duce). I've tried getting a straigh answer and all I get is "it's special" and if it's not used it can void your warranty. My best guess is that it's a no/low ash oil like what is required in the new 6.4 PS, 6.7 CTD, & 6.6 LMM.

I posted this elswhere before I found this fourum. I have two TDI's in the family, an 05 Jetta wagon and an 06 New Beatle. Is there an air intake/filter system that will give me any noticable power increase. How about some of the systems made for the 1.8 turbo gasoline engine?
Nope! VW has there air/fuel ratio so dialed in, that you won't notice any difference. You will just get the benefit of a re-usable air filter. I must also warn you about the oil air filters, if over oiled they WILL damage the MAF sensor!
