Hi Quinny,

 

Replacing an EGR valve for £1k is over the top.  You can buy a new genuine Jaguar valve on e bay for £170 each.  Having looked at them it does not look too difficult for a DIY job, but if you want it done cheaper and reliable garage will probably  of it for no more than three hours about charge.

 

A Jaguar Main dealer will do the same job for about 5 hours [which will include a tea break or three] at about £140 an hour.

 

The other and cheaper option is a terraclean service for you car   --  this is very good for diesels, and coupled with the Millers EGR cleaner will save you quite a few shillings.

 

Regards,

Peter,

Thanks for this. I will try the Millers ERG cleaner first. I quite fancy dropping it into Sports mode and giving it a "blast" on the motorway.

Regards,

Quinny

Hi Quinny,

 

The 2.7 diesel has two EGR valves on either side of the engine, but when they get stuck the engine warning light comes on and if you have a OBD2 code reader it will flash up the code, P0420, I think which indicates too much exhaust gas in the area not getting into the Valves.

 

There are several EGR valve cleaners on the market - I used Millers EGR valve cleaner once  and it worked [less than tenner from 

Halfords].  The other way to cure a sticky EGR valve is to get the car on to a fast road, press the S button and give the car a blast. 

 

Cleaning out the valves manually is possible, but I don't get dirty hands any more, so I haven't done it.

 

But you don't need diesel fumes in your car, so you are choosing the right course of action.

Welcome to the Club, John.

 

Try switching on the interior air circulation, and if that stops the fumes coming in then it must be a leaky air circulation duct. Also try closing all the air intakes and switching off the climate control.

 

There could well be other suggestions that could assist.

 

Regards,

 

Peter.

Thanks for the reply. I have tried what you recommended, and the interior air circulation does help, although as you will be aware, this function is on a timer, which defaults back to normal after about a minute.

I have made some enquiries, and I am being pointed in the direction of the emission valves. Apparently there is one on either side of the engine. I have been told these carbon up through time and stick open, giving the condition I am experiencing. I have also been told it is about 1k to change them.

Quinny

I have a 2006 2.7 Diesel Sport S-Type, which recently has developed a dangerous fault. When idling, diesel exhaust fumes emit from under the bonnet, and make their way into cab via the air ducting. I have stopped using the car as I feel it is slowly killing me. (A slight over exaggeration, but dangerous). This only happens when idling. When accelerating and up to speed all is normal. Does anyone have any ideas???
