TD4 EGR Valve

titchfield9 · Sep 6, 2018

Hi all, my EGR valve is frozen solid closed. was going to use the EGR delete, then realised its an automatic fail on the MOT now since May to replace the EGR.

I have a pierburg 7.28264.00 the price is crazy. Rimmer Bros quotes over £150 copy £500 gen
Found Landy part LR005791 or WAV000040 is this the same item?

Have an mot later this month so want it working. The EGR delete would show out like a saw thumb.

Google is your friend. I bought a second hand egr after blanking mine and not keeping the EGR valve for just over £20.

Been on google was first point of call checking the Pierburg number 7.28264.00 on the body. Other is a BMW part number and you just add zeros for them.
Found a new LR005791 for £45 hence rather buy new than second hand. Think that's what Rimmer Bros offered me. Yes they are on there but its if they work or not.

They are usually guaranteed for at least a few months. Long enough to pass an mot then blank again.

mine has past its MOT last week with an EGR blank still fitted
I guess its were you take it and if they are bothered to look

Someone correct me if I'm wrong, but blanking the EGR is not an MOT failure as far as I know. However, dicking around with the DPF, if fitted, is.

As of the May MOT revisions, any tampering with the EGR or DPF will fail the MOT, if it's spotted.

Apparently it is from May, you can not alter the original vehicles emissions control on any year.
If its picked up, its a Dangerous fail and the car can not be driven, hence looking for a new EGR, otherwise would have left as is as its jammed with the divert closed.
It doesn't have a DPF so that's ok, also it has to meet its original emission rating as well not the previous higher rating.

Heard some have passed and others have failed.

As you can clearly see it wasn't going to take a chance.

If there is an MOT tester on here would be good to clear this up.

Remove the EGR from your car and give it a good clean, do the manifold also, and the MAP sensor, I can not see why it will not then pass the MOT.
Your EGR and manifold could look something like these below and once they are cleaned properly will still work as they should, worth a go.

You could also gut your original EGR and turn it into a EGR bypass last photo's below

Thanks Artic2

Its off the car and been cleaned, its was so bad, scrapped the crap out but its stuck solid in the bypass closed position. Its been soaking all night with WD40 but no joy in freeing it up. Will clean the others, I here oven cleaner boxes the manifold the world of good.
Have found a Pierburg EGR from Germany that's a more acceptable price of sub £100

The pictures you posted are the item I have. was just very surprised at the cost of these things for the size and what they are.

Wonder how much one cost 6 months ago, or how much one will cost in 6 months

When you say stuck solid how have you tried to move it, because if you try to move it by pushing it I doubt you will, it needs a vacuum to make it work, I have never heard of one failing completely very puzzling.

I know Arctic has done several of these, If I remember correctly, he converted the original EGR on SWMBO's into a bypass.

Arhh did it pass the MOT though

I bet the tester never knew, the intercooler set up is better on the R40 in my opinion less turns and bends,

Twice

If the EGR is stuck shut, then why not just clean it out and fit it?

longdog · Sep 7, 2018

Clean the EGR out, refit it, and block the vacuum pipe with a ball bearing/small screw before pushing it back on.

titchfield9 · Sep 8, 2018

The reason I want it working is to pass the mot emissions as its been reduced for my 2005 car from May and I don't know what it did last time only have its smoke test result.
Don't want to take any chances with it not passing.

Its a shame as got a by pass on and its running far better.
Do have a new Pierburg one coming from a friend in the trade, got it at a very good discount for £75

We had it on a vacuum pump in the workshop and sat WD40 in the bypass and nothing would soak through so taken its knackered.
Had to near on chisel the crap out of it.

Nodge68 · Sep 8, 2018

If the EGR valve is stuck shut, the just fit in place of the bypass.
The MOT doesn't test the EGR functions, just that it's not been tampered with or removed.

Arctic... What is that stuffed up the end!?!? If you don't mind me asking? In the exhaust port? Neat blocker.
