Faulty EGR Valves on my D3

Hello all,

This is my first post so bear with me guys.

I had my D3 in for a service today and the've told me that my 2 EGR Valves are faulty and need replaced, being me not knowing anything about engines I surfed the net for info. All I know is that I've been losing power for a few weeks now, it gets better when the engine heats up and after that its intermittent.

I'm looking for advice basically, after surfing a bit I see there are blanking plates available which I have seen on Ebay, is this the best route to go down as I see from a lot of posts people are doing it with no after affects?

If this is the best route, is the blanking plates/screws all I need or do I need the gasket as well, people are talking about butterfly thingy's - I'm sooo confused - Please help?????????

Stephen

Hi Stephen,
Accepting that the EGR valves are faulty and that you want to blank them off rather than replace them, have a look at, site sponsor, Bellautos blanking kit.

Being in Lanark your pretty close to Gibsons of Cumnock, they'll suply and fit a blanking kit if your not confident in doing it yourself or has been said in above post B.A.S do one but you'd need to fit it. I've had mine done for acouple of months now and the difference is astounding.

Welcome to the forum and watch out for some days out at Drumclog that you can join in.
 If in doubt............flat out.

Thanks for your help, this sites brilliant.

AlanG also sent me a PM, as much as I would like to do the job myself I might need to get it done by a mechanic. The difference with getting someone other than a LR Garage is that they could possibly show me around the engine and maybe build my confidence a wee bit, I've serviced my other halves car but its just a wee punto, a D3 under the bonnet is quite daunting.

Had a day at Knockhill last year would love to take you up on the offer at Drumclog, is a it a proper off road course??

The D3 under the bonnet is only scary because it's covered by plastic - pull the cover off and have a poke around....you'll soon see that it's all fairly straightforward and like most other modern engines.

To be honest, fitting simple EGR blanking plates is a very easy job. Fitting the full blanking kit from BAS would be my option (it's what I did) and is only a bit more complex, but there's not much skill needed - the kit comes with excellent instructions - just an hour spare and some patience.

It would be a good way to build up your confidence Thumbs Up

Thanks,

What's the difference with blanking plates vs. the full kit?

Can the parts be fitted from the top of the engine or do you need to get underneath ie are there ramps involved etc?

I take it your car is running fine now you've fitted the parts?

The blanking plate just blanks off the outlet from the EGR valve by fitting a thin shim/plate inline.

The full blanking kit provides thicker plates to seal and blank off the EGR valve output and also the other end of the tube which goes into the throttle body. It is also recommended to remove the butterfly valve.

The first one I would say takes 30 minutes, the second one 60 minutes - both times are really taking your time and assuming you haven't done it before.

It can all be done from the top of the engine (put the D3 in access height first to make it easier to reach in).

My D3 was working fine before but was 3 years old Shocked - I did it as a purely preventative measure and being a 2006 model there are no real downsides. If I was still in warranty I honestly would not bother doing it.

Cheers,

Not sure what to do, I'll probably order the parts and decide from there but I need to do something the lack of power is frustrating me.

I came across one of your old posts, a lot of the posts etc I've seen is that fuel economy is better, is yours worse after fitting the parts?

Thanks again

Stephen

Mine's worse, but then again my EGRs were fully funcioning when I blanked them.

If you have an EGR failure than it's likely that you'll have such poor consumption that you'll see an improvement upon blanking, but my experience is that it consumes around 0.5L/100km more Thumbs Up

Oh yeah its a proper off road, many of the sections are for quads and scramblers others for heavily modified 90's and ML's. Also a lot of mod'ed jimnys and vitaras bombing about. Check out Alan G's youtube page for some shots of what we got up to a couple of weeks ago. There is enough to keep you going for 45 mins easily and by the time photo chances are taken into account you'll be 90mins plus plenty of guys to keep you right.

The guys at Gibsons i'm sure will be more than happy to let you poke about while they're working and show you fully whats going on.
 If in doubt............flat out.

Stephen,

You sound as wet behind the ears as I am on this subject and these great guys on the forum have been giving me some good advice. (I can just about top up my water bottle, inflate tyres, fill with diesel and load the CD player!)

It sounds like you have exactly the same problem as what I am experiencing with my D3 (no power when cold and improvement once the engine has warmed up with lack of kick-down here and there)

I have booked my car into a reasonably priced local Land Rover tinkerer on Tuesday for a diagnostic check but it sounds almost inevitable that it's the EGR valves.

If it is the case then (shock horror) I may just have a go at doing the blanking kit exercise myself, so I will let you know how I go on if I attempt this. (I think I'll bottle it)

The only thing that concerns me (other than having to lift the bonnet up) is having to ensure that NOTHING gets dropped into any of the holes during the loosening of nuts/bolts etc.....

I am not the best at avoiding disasters in this respect. Think Frank Spencer...............

I'll keep you posted....

Just work on ther assumption that if anything can drop into a crevice, it will. So, stuff the crevice with a rag or dust sheet. Also, one of those cheap 'magnets on a stick' is invaluable in my experience of kit car building!
