I thought I'd just post my recent experiences regarding the pesky EGR valve on my 55 1.6 tdci focus. Had to act following numerous and increasing limp mode activations and associated red cog illuminations. Spent a few evenings on this forum which convinced me that blanking it off was the way to go. (thanks to all the expert contributions)

First tried unplugging the EGR valve with very positive results although it brought the engine MIL light on after the 3rd start. Bought a stainless steel plate off flea bay for the price of a pint and fitted it on Saturday.

I only removed the engine cover bracket and pushed the fuel filter out the way 6 bolts in total. Found no need to remove the plastic scuttle or wipers. Used the wife's small mirror to see the 2 bolts on the EGR and slacken them off. Slid the plate manifold side of the gasket and tightened it all up etc. Including re-attaching the plug and restting the MIL it only took about 30 minutes.

Happy to report 250 miles with no limp mode and no engine lights on. If you're in any doubt, give it a go. It's not challenging and the benefits are immediate.

All the best

I did exactly the same on Sunday with mine and have to agree with your comments..... Easy to do and instant results :)

Is there any sort of performance benefits to the blanking in your experience?

probably no performance benefits but its the crap from building up and throwing engine lights

Agree with sal and lotty.Glad I did mine now and its not as hard as I thought to fit.Just got to clean out the inlet manifold now to really benefit from the cleaner air in the engine but its a bit trickier to do...No lights on on mine yet too... :D

Hi - what benifits did you notice?

probably no performance benefits but its the crap from building up and throwing engine lights


Theoretically there are performance benifits because the burnt exhaust gases that are normally injected into the engine are replaced by (relatively) cool clean air,

The EGR valve/ system may operate at specific revs/ conditions (eg at certain low revs/ at part throttle) so the EGR valve may be designed to close at higher revs or full throttle

So the difference fitting a solid plate may be quite subtle and may be percieved as "smoother running" or "less flat spots" and not "better performance" but nevertheless, the engine should pull/ pick up better within from low revs (in the "EGR zone") - so a slight performance improvement is normal


To get the full benifit, the inlet manifold/ EGR valve needs to be cleaned out completely, and the ECU reset. this may give a more noticable improvement

If 2 solid plates are used, (one near the inlet/ EGR and one close to the exhaust manifold/ EGR cooler) and the EGR pipe is removed, this can have further performance (and efficiency/economy) benifits, because the inlet stays cooler (cooler = denser charge = more oxegen per cc = more power) and the volume between the engines exhaust outlet to turbine is reduced/ less exhaust energy is lost, reducing lag, increasing throttle response/ power

Again, this is not a massive gain, but adds up in conjunction with other modifications, like remaps, bigger intercoolers etc, and economy is liable to be a little bit better. And reliability (the EGR cannot go wrong if its not there!)

My obd scanner says that the egr flow is normal...How can that be seeing as its blanked??? :unsure: Interesting...Also the flat spot I was having is just my right foot,I only slightly depress the pedal normaly but today I booted(put my foot down) and boy did it fly(well for an estate it wasn't too bad)lol...and no flat spots... :)

Hi I have a 2004 c max which has been plugged into the computer and comes up with egr fault. Also I have a battery drain as the engine managements staying on because of a fault. I was wondering if I put the blacking plate on will this sort this. Thank you

I blanked the egr valve about 8 months ago. Less smoke, beter pick up, no lights in the dash. but I also found I'm getting less mpg. was having around the 50 mpg mark but it dropped to anything from 40 to 45.so took the plate of. Now it's back up to the 50 again.

Is this normal??.

Exact same thing with me mate.
Was getting 49 MPG around 4 months ago, blanked EGR and MPG has dropped significantly to 42 MPG.

Thinking of taking the blank out to be honest.

I found my MPG improved (as well as the performance) with the EGR blanked, the trip computer / displayed MPG may not be accurate/ may not be reading the true MPG and perhaps fitting a blanking plate changes the displayed MPG  

 

Theoretically  the MPG should improve with the plate fitted (cleaning out the inlet manifold and resetting the ECU (as well as the trip computer) may help/ get the most out of the plate)
