[Vwdiesel] TDI error codes, wanted to try this group first.

[Bryan Belman]

I think these are pretty common on the TDI with 130K.
I have never really gone in and cleaned up the intake manifod, for starters.
I have the Free-ware Vagcom, so I only get deffinition of the 1 code, I will 
look the other ones up later today.
16516  -  O2 (Lambda) Sensor B1 P0132 Intermittant Signal
16512  - P0128
18627 -  P2195
17524 -  P1116

Any thougts on the first one, what to do first, pull it out and clean it?
