Hi, I have just removed the EGR valve and cooler pipe off my 2007 Mondeo ST TDCI. All running fine but engine fault symbol lit up. The EGR was the Electric connection type. I have disconnected the battery and reconnected it after a few minutes hoping the ECU would relearn and reset. Is there a dedicated fuse for the EGR valve which could be removed to eradicate the engine fault light . I dont like the idea of taping over the symbol, and hiding another possible engine fault. The car is blue finned.

Horrid shit egr is lol I blanked it off on my golf

You will need to have the ecu remapped to remove the egr from the system.

grcossie

Have you remove egr valve or bloked it?

johnlboyer

Thanks for your replies, I know about the remap to delete out the EGR(Ł250)which seems overkill as the car is already Bluefinned. To answer the 2nd post, the EGR is removed totally and replaced with EGR-DELETE LTD kit.

You will still need to tell the ecu that it is no longer there as it currently thinks it is not working, thus logging a fault code. The only way to do this is with another remap that removes it from the system. Overkill or not, it's the only way around it.

I am running 3 cars and I am retired so some careful thought is required. I think I will learn to live with the engine management light on all the time. As there is an oil warning light and a temperature guage, that should be enough insurance to warn of impending problems. On the upside, the car has been averaging around 38 mpg but today, I did around 75 miles at motorway speeds and the average has gone up to around 43 MPG and the car feels quicker and smoother. So, a little bad and a lot of good. I will clean and keep the EGR valve and cooler pipe so as I can revert back if I should wish to at any time.

Don't forget it will fail an mot with the lamp on. Your logic sounds a bit daft imo. The car is now in limp mode so running a basic 'get you home' map.

My Kuga 2009 2.0tdci euro4 with bluefin, have run 4-5 years with egr blocked, no engine lamps or fault codes. Have done this on others euro engine with same result

johnlboyer

Hi, I understand your comment regarding failing MOT due to warning light on. Regarding my logic, surely if the engine has its life blood, oil and water and is running at correct temperature, it should be OK. As for the car being in limp mode, how can that be. It is flying.

johnlboyer

When you say EGR blocked, have you used a blanking plate at the cooler pipe/EGR connection. If so, is the plate solid or holed?. Does your EGR have an electrical connection plug, or vacuum pipe?.

grcossie

It`s a solid plate between the egr valve and egr pipe to inlet. It is an Electric egr valve. You must use a rust free plate, to blocking

Checked on MOT status today. EML not part of current test criteria. My MOT testing station confirmed today, and I have checked latest MOT items list. By the way, car still running great and smoke almost non existent.

Technically, it should fail, as per point 1 of this,

MOT Test of Exhaust and Emissions



Part of the system missing or excessively deteriorated
(from February 2014 a missing diesel particulate filter, if originally fitted, will be a Reason for Rejection)
>A catalytic converter is missing where one was fitted as standard (on vehicles subject to a full cat test only)
Mounting is missing or damaged so that the exhaust system is insecure
There is a major leak
>The system emits appreciably more noise than a similar vehicle fitted with a standard system in good condition.
>Class (v): Exhaust tailpipe positioned so that fumes are likely to enter the driver or passenger area.

And also,

MOT Test of the Instrument Panel

Warning Lamp

Missing
Does not illuminate
Indicates a fault
(For ABS) does not follow the correct sequence


So it should really fail on both points, however if you have found a garage lenient enough to pass it, good luck to you.

johnlboyer

My garage is not lenient, in fact quite the opposite which is the way I like it. All items on current test list are dealt with and tested or inspected. Sorry, we will have to agree to disagree.

Rowe

how is the tester suppose to know the the EGR system is missing?
also, i'm not entirely convinced the EML is actually classed as a warning lamp:

If you've got one of these warning lights then it must now work correctly:
Electronic parking brake
Electronic stability control
Headlight main beam warning light
Electronic power steering warning light
Brake fluid level warning light
Seat belt pre-tensioner warning light

studabear

If eml was a reason for rejection 90% of Vauxhalls would never have a mot.

I test loads and loads of cars with eml on and rarely are the emissions a issue.

johnlboyer

Absolutely agree with that.
