white90 Posted November 25, 2005 Share Posted November 25, 2005 Black smoke = unburnt Fuel Turbo unlikeley to be a problem. does yours have the Electronic injection pump? or does it havea proper throttle cable? Quote Link to comment Share on other sites More sharing options...
BogMonster Posted November 25, 2005 Share Posted November 25, 2005 I don't know what age an S reg is but it sounds like the EGR valve jammed open to me, this feeds exhaust gas back into the intake system to reduce (ha!) emissions but when working properly should close as soon as you demand full power, if it jams open the engine is trying to burn a load of fuel in not very much oxygen hence F all power and F lots of smoke. First thing to check anyway... Quote Link to comment Share on other sites More sharing options...
Jamest535 Posted November 25, 2005 Author Share Posted November 25, 2005 Just spoke to the garage, they said that there is a mod regarding the EGR valve. They said the EGR valve is a common problem, and to take the EGR out and replace it with a blanking pipe, or something like that..., So, lets see if thats cures the problem with it smoking and no go!!!

Guest weeble Posted November 27, 2005 Share Posted November 27, 2005 I take it you looked at the obvious things like the air filter?. Quote Link to comment Share on other sites More sharing options...
Jamest535 Posted November 29, 2005 Author Share Posted November 29, 2005 Just heard from the garage where I got the Disco from, they have done the EGR mod and everything seems to be fine. They said they have took it up the road for a spin and the power is there and no smoke, but I will check it tom when pick it up. Do you think that might fix the power dieing off then coming back on again arind 3000 - 4000 revs??? LAst time they said its the Waste gate valave???

BogMonster Posted November 29, 2005 Share Posted November 29, 2005 Could do ... the EGR valve opens at certain part throttle settings but then should shut off above certain load/speed ranges - maybe it wasn't shutting the valve when it should. The whole EGR system is rubbish anyway and any Tdi engine which has it is better off without it IMHO. If it ain't there it can't break Quote Link to comment Share on other sites More sharing options...
