Fuzz Posted September 7, 2014 Share Posted September 7, 2014 Hi guys, I have a 1.6 tdci focus 07 and previously I used to hear the sound of the egr valve clicking for some seconds after turing off the engine, however, recently that sound has disappeared I dont hear it anymore. There are no fault codes present and the turbo seems to boost later than it used to, before the boost was felt at 1750rpm but now it boosts at 2500rpm and doesn't boost all the time it struggles to get up to speed. Please help me solve this problem. Fuel consumption is not good 39.4mpg average. Thankx. Quote Link to comment Share on other sites More sharing options...
FOCA Posted September 8, 2014 Share Posted September 8, 2014 It is possible the EGR valve is leaking or faulty You say there are no fault codes present - what type of reader did you use? Quote Link to comment Share on other sites More sharing options...
Fuzz Posted September 8, 2014 Author Share Posted September 8, 2014 I used an obd 2 scanner as well as the other one from the garage one that shows you more details like egr position and a lot of other things. Quote Link to comment Share on other sites More sharing options...
FOCA Posted September 8, 2014 Share Posted September 8, 2014 May be possible you have lack of boost - would explain lack of power / lag and it might not show up in codes Have you got a boost gauge? Quote Link to comment Share on other sites More sharing options...
Ianb Posted September 8, 2014 Share Posted September 8, 2014 Perhaps just blank it off... That's what everyone else seems to do anyway... :) I've not got round to it :( Sent via carrier pigeon using Ford OC Quote Link to comment Share on other sites More sharing options...
Fuzz Posted September 8, 2014 Author Share Posted September 8, 2014 No i dont have a boost gauge, however the obd scanner shows that when it boosts its between 7-11 (psi /kpa) one of the two units cant remember which one is correct. Wanted to blank it off months ago but damaged one of the bolts corners while trying to take it off..lol Quote Link to comment Share on other sites More sharing options...

Wanted to blank it off months ago but damaged one of the bolts corners while trying to take it off..lol if its 7-11psi that seems quite low for a turbo-diesel, i read that 14psi is typical for a 1.6tdci, some other diesels run a bit more, thats under load though Quote Link to comment Share on other sites More sharing options...
Fuzz Posted September 10, 2014 Author Share Posted September 10, 2014 Thanks for the advice guys, will have to look more into getting the best out of the turbo somehow, but I think there may be a fault with the ecu or something seeing its not self testing the egr as it used to.
