Orange Coil Light On Loss Of Power Fault Code P0406

11 posts in this topic

Hi all, I would appreciate any help I get on this one its
driving me nuts.

I will try to be as detailed as I can I know you are all
thinking it’s a faulty EGR valve but let me explain.

I brought a ford Mondeo 2006my 2.0 TDCI 130BHP for the
missus yesterday. As soon as we get it home the orange light starts to flash
with a small loss of power, not exactly limp home mode though!!

I have had the fault codes read and the only one found by a friendly
AA man is P0406 which I know points to the EGR valve. However I have changed
the EGR valve for the one off my car (the same model) and tested it using the
vacuum pipe directly from the brake servo while the old EGR valve was
connected. So I know this works. I also fitted the old EGR valve off the new
car to my car to see if the fault occurred and it did. So I thought hay presto
problem fixed the new car was running fine no faults no light great.

NO once the car cooled down the orange light came back on
again. Reading the many forums and fantastic advice given my attention then
went to the EGR solenoid which I tested with a multi meter and got a reading of
between 12-13 ohms but just in case I also swapped it for mine just to get the
new car working. After this took it for a test drive once the fault cleared (as
I don’t have a reader took about 20 restarts) all was great again.

Again NO once the car had cooled down the light came back on
again with again a slight loss of power.

Can anybody help this is driving me crazy I don’t want to
take it to a garage as I am more than capable of changing out parts if I know
what needs changing.

Any help would be appreciated

Thank you

Jason

Hi Mick,

Thanks for the answer I did check the supply voltage to the EGR solenoid and was getting between 13-14 volts with the car running. Do you have any other ideas as to what it could be is this something you have experienced before?

Thanks

Jason

This doesn't particularly help but personally, I'd have it back to where you bought it from and save the aggravation - once you start tinkering with stuff by yourself, your statutory rights go out the window. Under the Sale of Goods Act, the dealer is obliged to fix it at his own cost, given that a major fault has surfaced within 24 hours of purchase so it was sold unfit for purpose and not as described. Contact the Office of Fair Trading for more info.

Hi BigD

I am not sure where I stand on this one as although it was from a trader it was sold as seen as it was a part exchange he had in?

I did get the car for a good price as long as this problem is not a big one! any suggestions?

Thanks

Jason

That doesn't matter. He can say it was "sold as seen" as much as he likes, but he cannot bypass the Sale Of Goods Act by trying to get all "wordy". You still have statutory rights no matter what the dealer says.

The car is not fit for the purpose you bought it for - simple as that. You really should give the Office of Fair Trading a call tomorrow - take note of exactly what they say (which will be pretty much the above) and throw that at him if he gets funny, which, from what you've said I'm sure he will.

Sounds like a injector has given up I had the same problem with mine. You need to get a diagnostic plugged in yo give you the code

If it come back injector 2 or whatever above max threshold that means it's past its pulse rate and needs replacing and recoding but getting a injector ain't cheap Any where between 200 and 500 just for one injector.
