So I came across 'Wynn's EGR3 Cleaner' today.
http://www.autosessive.com/9/section.aspx/1685/Wyn...

It is meant to clean up the inside of EGR valves, and make the engine run smoother. Sounds ideal of my TDDi focus, which is pretty rough at times, and has had the very occasional power hicup when pulling away.

I've heard lots of good things about on various forums and reviews. The concept being that you let the engine idle about 2000rpm, and spray it in the intake body in 1 second bursts. Its meant to remove the build up of gunk in the EGR valve.

Found this video too: http://www.youtube.com/watch?v=1DhYk3Mm8HQ

Has anyone used this before? Does it work?

On the other hand I've also heard that it doesn't clean it 'Properly' and the only way to do so is to take out the EPR valve and manually clean out the gunk. But this is much bigger job.

So I'm weighing up the options really.

What do you guys think?

Better to take the thing off and clean it, or better still blank it off.

It sprays down your inlet so I don't much of it will actually get inside the valve to clean it.

Carb cleaner is significantly cheaper.

I blanked off the EGR in my Mondeo TDCi engine, worked a treat. Actually made the engine a little more responsive too.

Sounds promising tongue out

Any drawbacks?

A lot of cars will stick a engine management light on and may reduce power if you blank the EGR off.

Ist it just carb cleaner in a smaller tin yet twice the price?

Is there going to be any solvent left after it has been through the entire engine?

Great stuff! picked up a can out of curiosity after seeing it in the local motor factor and put it through the air intake pipe of the golf mk5 tdi. The amount of soot that came out of the exhaust was a real surprise, the car never smokes normally even on full throttle. Its cleaned something, because it runs quieter now and I actually get some decent throttle response below 1900 rpm whereas before it was just nothing-turbo boost-nothing, it pulls right from tickover now.

Doesn't this just shoot all the dissolved crud through your engine or have I missed a link in the combustion cycle somewhere?

Believe me when I say this but cleaning the EGR valve will be easier than cleaning the interior of your car.
Not sure where your EGR valve is located in the Focus but in the Mondeo it had 2 nuts to the side, 2 at the back, a jubilee clip and an electrical which just pulled out.
WD40, toothbrush, some rag and 20 minutes later a spotless EGR valve.
Noticed no difference however but thought it would be worth doing anyway.

Might've been this one?

Not a hard job on a Mondeo, can't see it being too difficult on a Focus?

Snake oil of the highest order. Your EGR valve will be upstream of the point where the EGR enters the inlet air. So assuming the idling engine does not swallow the cleaner straight away, it then has to flow against the exhaust gas to get to the valve.

I've had EGRs that have taken 2 days to chisel clean so i doubt this stuff will clean one of those but use it on a low millage car every year to keep it clean i will work, 10K boostworks IF you use it on mildly clogged inlets.

That's because your EGR wasn't dirty, trust me it would take more than 20 mins with a toothbrush and WD40 to clean a clogged EGR, more like a chisel a drill and 2 days work frown

All that jazz

If you run it on the standard part-bio crappy diesel then yes, but if you use a premium diesel or shove some Millers Diesel treatment in on each fill (same shizzle as V-Power but cheaper) then the most your EGR will have on it is a light dusting of carbon, same for your inlet ports. I have surprised many a mechanic who has instantly said more than likely clogged EGR when taking my motor in with some running problem, only to find that it's like new. Since using V-Power (or Optimax as it was back then) in the early days and now Millers Ecomax treatment, I've never had any EGR, injector or any carbon build-up issues since and I do lots of short runs. A rare case of stuff actually doing what it says on the tin for a change.spin

All the carbon dissolved off easily with carb cleaner.

And I use 'normal diesel'

Yep. This isn't even the valve either, just the mini-manifold that the EGR itself bolts to.

Before


After (still needs a 'final' clean with some carb cleaner).
