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

[jeebowhite]

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

[salsheikh]

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

[jeffnat68]

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...

Hi - what benifits did you notice?

[FOCA]

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??? 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...
