I see kits to remove troubled ERG valves. basically neat blanking plates.
has anyone had experience removing the valves?

What does the dash warning lights do? when the valves are no longer connected? doe you get a constant ERG warning light to drive you nuts?
I am looking at the 2.7 Diesel engine fitted to a 2005 S-type, but it applies to any car with ERG.
are the hard to fit remove on the 2.7D? as I am considering remove and clean...any tips?

Stan,

Let me start by saying I have no idea!

Reason for my post is twofold:

1. should that be EGR (Exhaust Gas Recirculation) valve
2. any reason you chose to post in General rather than S-Type section

I can move it to S-Type section if you want.

Hi Stan, I can't help with the specifics of the EGR on the S type I'm afraid, but have had recent experience on a few other cars, and they're all pretty much the same tbh.

As for the blanking plates?
I've seen them like you and read about them, but have never fitted one, although it looks very simple. Some people say they have no issues with CEL after and some say not.

The guys in the S type area will be better placed to advise I'm sure, but removing and cleaning is not a lengthy process, although can be very dirty obviously.

An hour or so removing a few connections and a few retaining bolts is usually enough to get it off the vehicle, £5 for some carb cleaner along with a toothbrush or similar and a rag is all you need.

I'd suggest while you're in there looking at the throttle body as I'll bet thats coked up too and will benefit from some attention too.

Once I'd done this work on my sons Vauxhall Astra, the car ran smoother, eliminated the hesitancy when accelerating and it generally seemed more eager / more responsive in all gears. I'm not sure about any improved mpg but as I haven't logged it but could be a small gain there too.

Good luck

 

Stan, on a diesel of your vintage, removing the EGR valve should not cause any issues. You get into the 2008 versions and newer, then you are going to have issues.

In short, what you are doing is preventing the vehicle from taking a small amount of the exhaust and burning it a second time. This is done to help with fuel mileage as warmer intake air causes the fuel to be turned to a vapor faster, leading to more rapid fuel burn and also reducing emissions since the same air is being burned twice. The down side is that the warmer air is also less dense. Less dense air means there is less oxygen to burn the fuel, therefore, power goes down. Hence why a lot of people want to get rid of them, to get more power.

As for installing them, can not speak on that. I just know the concept behind why they are there and the pros and cons.

 

Hi Graham,
yes please feel free to move the post, and yes again I was talking about the Exhaust Recirculatione Valve

Stan,

Moved and thread title amended to 'EGR'

EGR doesn't operate when max power is requested, does it? So, won't reduce power. I guess early cars maybe did but this is a Jag not an old el-cheapo heap!

This sounds like the kind of mod you might have done 10 or 15 years ago to one of those heaps.
