All, First what a great resource and I am hoping someone can confirm I'm on the right track here. I am getting the following errors 02-16 It only recently threw a 02-17 once and has never again. I have changed out and put in new bobcat hydraulic fluid. Replaced main screw on hydraulic fluid filter. Also did engine oil, air, fuel filters as well. Now I get the error message more often and sooner during use. The only thing I can see is I've followed the lines from the drive motor and my T200 with approx 3700 hrs appears to have 3 of the aluminum cannister type filters. One on each drive motor line and the one main one at the hydraulic Junction bolted down to the frame. So I appear to have 3 of these. The Junction one will be easy to check.......any tips on getting to the ones on the drove motor lines....? Also I am assuming from everything I've done it is one or all of these that are bad or causing my codes? Or is it something else I am overlooking. Thanks in advance. Scott
