EGR Error Code - following EGR valve clean

[sgould]

It's inside the wheel arch - driver's side.  Jack up car and remove wheel.  Undo the two or three screws and peel back the plastic liner.  The ECU is just there.  See picture above.

If you put the wheel on full left lock, you might just get enough space to undo the liner bolts and reach in.  But, wheel off is the recommended way.

i have the switch cleaner now,

The EMU (ECU)  best way to clean the connections

Is there a cover to remove and then take the connections OFF and clean and reseat them all - whats the consequences of doing that - will it reset anything if i remove a connection -

do i need to undo the battery and if so - what again are the consequences of that - windows pinch, key activation, etc etc

just so i know what to expect and dont do

looked at some youtube tutorials - but could not find one for the 93 in the wheel area

Doesn't seem to be anything special.  Just be careful.  Ease things apart.  Don't touch the pins.  Don't bend the pins. 

Make sure that it's all square when you put it back.  Don't force it.

Be really careful with the ECU, the connectors get covered in dust and muck and can be very hard to removed and very often will break when you remove them. This isn't a real problem as you can still undo them but you must be *really* careful. If you damage any pins on the ECU then you're likely to end up with a £700 bill and this is potentially an easy thing to do if you are not *really* careful.

I also doubt that fiddling around that end is going to resolve the CEL given the described problem.

thanks - just had a look under the wheel is it front of wheel or rear of wheel
screen shot looks like it the front of the car wheel
but these can be deceptive

@Audax
Thanks for that advice - any way to test the solenoid via a couple of wires off the battery , is it just a simple 12V DC on/off solenoid - last one I sorted out on a car was for a starter motor quite a few years back, when cars had points and you used feeler gauges
i will take it off again and recheck the extreme ends, but i was pretty sure I did all that and really made sure , as it was the third time I have taken it off

I'm happy to try anything if i can find the instructions on what to do , and although a novice on modern cars,  I do have some mechanical and electronic training as an apprentice and then worked on older cars. But they did not have anything like the electronics or special settings

It's at the front of the wheel arch.  There's a picture of what you are looking for in my earlier post.  It looks like the connectors are at the bottom.

Much the same as me really 

I used to do everything on my old MG - nothing was really a challenge other than the electrics - but now modern electrics are my worst fear on all modern cars ...Every damned thing seems to be connected!!

.Every damned thing seems to be connected!!

or you need special equipment or computers to link into the car - well I know about electrics and computers
But taking a bit out and connecting up to the battery and testing are all long gone.

I played around with old escorts and beetles and with a haynes manual  did my own serving and brake changes and most repairs for quite a few years

anyway, no garage available so i have positioned the car so i can at least get to the front safely , without anyine running me over , hopefully get to it over the weekend, if family do not take over

thanks for all the suggestions - any others while the tools are out welcome

i cleaned the MAS and MAF on saturday
Thanks - its been working perfectly - upto today started with no error about 25 times

my wife used the car today and drove 100miles and on the last startup in failed again

The code reader I have reads the live MAF and MAS sensor data

I just restarted 5 times just now after resetting the code - its been working fine - how I hate intermittent faults , even on PCs they are terrible things

so , next steps to look into are

the throttle body and EGR clean with Mr Muscle, the connections on the ECU and the 15min battery reset - so will plan those in over the next few days, and just go through a process of elimination

Also the gasket is available locally for £3.00

interesting my wife said it drove differently after the light was on and did not have the pull in the gears until after the revs/turbo kicked in - i have not noticed - but maybe a stranger , as she only drives a few times a year , may see it differently - But then if the engine light is on , it maybe a factor - does not seem lick limpmode , as i had a saab go into limp mode and it drove very differently

Thanks again
