Very interesting read that.As I'm new to Ford Transit engines,I'm feeling my way,so to speak,but because all modern engines work,more or less,on the same principles,it should be simple to kind of figure things out,if you know what I mean.On the EGR issue,this component,I suspect,works on vacuum,so stopping the vacuum prevents the valve working,however,you have to make sure that the valve is in the "closed" position when you stop it working,otherwise it will interfere with the inlet manifold pressure (MAP) readings that are being sent to the ECU.MrMPuk wrote:http://fordtransit.org/forum/viewtopic.php?f=5&t=60324

This confuses the ECU as it's used to taking readings from different sensors,and allows the correct amount of fuel to be mixed with the air present in the manifold.This can lead to over fueling,hence less MPG!,(in theory).The reason the engine keeps going into "limp mode" is because the ECU is uncertain of what's happening and is doing it to safeguard the engine,(pulling things back so to speak).Unfortunately,as I'm aware,because of all the sensors in modern engines,it's virtually impossible to stop the EML from coming on unless you have it deleted from the ECU program.Not all vehicle engine go into limp mode however,and continue to run quit happily,with the benefit of improved in the low down end,(torque),of the acceleration curve.Please be aware,this issue only applies to engines that have the EML/sensor present in their ECU, (Mk7 etc).On engines without this,(the Mk6),there should be no similar problems,you should be able to go blissfully on your way.However,there is still the question,does EGR blanking increase fuel consumption or not?. FELIXX.
That sums it up perfectly. However,on a Mk7 series engine,the ECU might compensate by over fueling.This is only theoretical,and has never,to my knowledge anyway,been proven.That's why I asked the question in the first place,to see if anyone had any experience in this area.FELIXX.martynx wrote:EGR systems account for up to 30% of the mass gas of the intake, so blanking will result in that % coming via the intake & will therefore have more oxygen, & more oxygen means what is present mixture wise will combust more efficiently....
Felixx wrote:What I'm trying to find out is will blanking a Mk6 have an adverse effect on the fuel consumption?.Because the ECU is not,I presume,programed to compensate for the drop in manifold pressure by over fueling,it shouldn't therefore,effect the fuel consumption,.............should it,???????????.

The copper pipe thing wont work as the intake is pressurised at about a bar above atmospheric pressure, & the egrs gas feed's in at a lot more than that - if it ran at a vaccum like possibly a petrol non turbo it would work
