VR6 Lupo Posted October 3, 2008 Report Share Posted October 3, 2008 hey, I have a vw bora 1.9 tdi pd 115 bhp, sometimes when i start it, it revs its balls off for afew seconds,this is problem 1, problem 2 i could be driving along and the turbo will just cut out, if i turn off the engine and restart it the turbo works again, but the turbo will still sometimes cut out again, it is doing my head in, i dont want to take it to vw as they will charge my an arm and a leg, any ideas anyone???? cheers gary Quote Link to comment Share on other sites More sharing options...

nfbr Posted October 3, 2008 Report Share Posted October 3, 2008 (edited) That seems really really odd. Have you done any VAGcom checks ? Edited October 3, 2008 by nfbr Quote Link to comment Share on other sites More sharing options...
lupo pd 150 Posted October 4, 2008 Report Share Posted October 4, 2008 Problem 1. A faulty coolant or fuel temp sensor can cause a pd to rev up when started ( normally a check light on dash )Problem 2. If you do get the fault memory checked there will be a fault regarding boost pressure regulation, the ecu knows the boost pressure is not within the range that it should be at that given rpm/load.It could be a number of things from a split vac pipe,boost pressure control valve or it could even be a faulty turbo (sticky vnt) Quote Link to comment Share on other sites More sharing options...
VR6 Lupo Posted October 4, 2008 Author Report Share Posted October 4, 2008 think it would be easier to drop a new engine in, would a pd 150 be a easy swap? cheers gary Quote Link to comment Share on other sites More sharing options...
