JST Posted January 17, 2006 Share Posted January 17, 2006 Have been asked to help out on identifying a 300tdi to fit into a def. from some of the photos i have just received of the FIP i notice a little black box above the arm for the throttle control. Is this an electronically controlled throttle or is it mechanically controlled but the black box on top senses the lever position then adjusts fuel, or is it a std mechical system like early 300tdi and all 200tdis? In other words can this setup be linked staight to the exisitng throttle linkage and run without any electronics. i have a feeling this might be one of the later electronic 300tdis, but then it could be something to do with EGR - just cant remember. Sorry dont have the engine number to hand Nay help greatly appreciated. Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted January 17, 2006 Share Posted January 17, 2006 It's a throttle position sensor for the mini-ECU to control the EGR. Unplug and continue as before. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted January 17, 2006 Share Posted January 17, 2006 As JB said, it's an EGR one so just tells EGR what the pump is doing, doesn't affect the operation. The EDC pumps have a whole load more electrocrud bolted onto them than that! Quote Link to comment Share on other sites More sharing options...
JST Posted January 17, 2006 Author Share Posted January 17, 2006 Jon, Steve many thanks for the help. good news that i was trying to remember what the one on my old G reg 300tdi was but it escaped me, eventually found some pics at home so all double confirmed. It will be removed prior to fitting! or ignored anyway, along with the EGR blanked off and the top pipe changed for a straight through one. thank you for the confirmation. mind now at rest well sort of Quote Link to comment Share on other sites More sharing options...
