Blanking off my EGR Valve...

26 posts in this topic

After having read about a number of peeps blanking off their EGR valve, I'm interested in seeing the results myself. Can anyone post a photo up showing me exactly where to blank off?

I've read a number of threads on the subject, but I'd still like a photo or piccy showing just where exactly I should be blanking things up.

Many thanks for any brave souls that have already done this and wish to share their experiences, wisdom or photos.

Opps - should have said - it's for a Volvo S80 D5 (163bhp) on a 2003 plate.

It'll throw a wobbly since your D5 diesel engine is far removed from the older engines talked about in that thread.

It's also illegal due to the emissions.

Clean it out and remember to give the car a good run to keep it cleaned out.

It's all over then net. Over the last 10 days I've owned the S80, I've read numerous posts on T5D5, VOC and VPCuk.

On almost all threads that mention the mixer and EGR, there's always mention of blanking the EGR off. Some folks claim it gives better performance/economy, others say it threw up fault codes on their dash. I'm just curious and was considering doing it, but as always, I find it best to post up on a forum to get the general opinion. If it is illegal, then I'll not be trying this little experiment out.

Again, but - if I'm to clean it out, where the heck is the little blighter? Anyone has a photo indicating it's location?

There you go, just searched EGR.

Hey Gaz

Nope - that's not it...

That thread is about the plenum mixer thingy. There is a small (very small) photo of the EGR valve on the 3 page of that thread, but where exactly is it on the engine - any photos, Bud?

Can someone circle the whereabouts of the EGR Valve?

Follow the pipe from the EGR mixer back towards EGR, it'll be near the back since it's 'Exhaust Gas Recycling' Valve.

Awesome, Gaz. Thanks very much for that. It's just what I've been looking for!

I took my mixer pipe off (the big silver thing at the front of the engine) with 3 bolts, then undone the two jubilee clips, and removed the pipe. You'll then so a hole, with soot

around the outer edge. Clean this out, but DONT push the crap in, make sure it comes out towards you. Also clean the mixer tube you've took off. Mine was quite clear, but

i used brake cleaner or engine cleaner to clean the mixer pipe out. Use rubber gloves aswell, as ive heard its cancerous :(

I took mine apart the other day. It was gleaming inside. I only bought the car less than two weeks ago from a garage and just before I collected her, they had a specialist replace 2 of the injectors and the intercooler. They've obviously cleaned out most of the system while they were at it.

Over the last two weeks, I've given her an oil and filter change, fuel filter, air con re-charge, pollen filter, reversing sensors, bluetooth kit, engine clean and chopped and changed a few things to my own personal liking :D

I did my pollen filter the other week. What was the fuel filter like to replace, thats my next job, then the rear parking sensors, of which im getting the number plate type ;)

Parking sensors are fantastic. I drove without them for about 2 weeks there (From getting rid of my C70 which had them to buying some for the S80) and it's amazing how much you miss them when you don't have them. It's not that you rely on them, I just find that them make parking so much quicker and not being able to see where the S80's rear bumper ends from the driving seat, they're a God send.

As for the fuel filter, I haven't got a clue - I had ye old garage fit it for me and kept my hands clean lol.gif

What does the EGR acutally do?

Obviously it recirculates exhaust gas.............but from where to where?

I ask because my Gen3 D5 has just started to behave as if it has no turbo (makes it v hard to drive) and the dealer has diagnosed a stuck/sticky/faulty EGR.

it recirculates exhaust gases back into the intake under certain conditions to reburn any unburnt fuel and thus reduce emissions. :rolleyes:

the problem is as the hot exhaust gases are mixed with the (reletively) cool intake gases it causes a carbon buildup. <_<

hope that helps.
