MIL light on was created by mickt
Daughters M13 2001 has decided that after 7 years of faultless behaviour to flash the MIL(engine icon) light or rather illuminate permanently at her. I have a disc with the manual details but the whereabouts of this DTC connector is a bit vague. Unfortunately the illustrations are of LH drive variety and although it mentions about RH being opposite I have had a look under the dash and did not spot it. Is it a "open" connector like the modern day vehicles and is it mounted on structure. I want to do the light test mentioned in the disc about flashing sequence and am assuming it is the icon that flashes that sequence. Anybody able to confirm for me.

If you mean the main OBDII diagnostic connector, then when you sit in the drivers seat, it is up under the dash by your left knee cap

If yours has the "manual" diagnostic connector that you can loop out the pins to get a code then this connector is up under the dash behind the glovebox. This is age dependent and newer ones do not have it.

Now I am confused. I looked under the drivers side dash and could not see a OBDII connector and so thought because of its age, 2001 and hardtop, that it would have the manual diagnostic connector. When were the OBDII fitted?

Got my head up the drivers side and located the OBD connector which is mounted on the extreme LH side lower edge of the dash with the input facing forward. Looking up under the glove box there is a loom running fwd/aft which has a plug poking out of it. It is white, rectangular and is a 6 pin connection but only five seem to be utilised. It is about 12mmx15mm. Is that the other connector you were on about?
First I decided to disconnect the battery for a couple of minutes then reconnected it. The light has stayed out and on her way to work this morning and has not reappeared. So that's good and now if it does I can perhaps read the fault.

So the Mil light has returned. I managed to read the code and it states "Exhaust gas recirculation". So is that pointing to the sensors or/and possible blockage of the cat? It cleared OK. The daughter is about to go on her holiday and is set to drive to the airport tomorrow so it was nice to find it was not a disaster message. Her car is booked for the parking so we do not want to change the car details.

The car has an Exhaust Gas Recirculation (EGR) valve, which the car us suggesting is at fault.

I think they can be cleaned or replaced.

Got the EGR valve off and the head,valve pipe and intake passages are clear of any signs of carbon build up.( Right awkward to get it off, I disconnected the heater hoses for better access but even then its a pain. The worse bit will be putting it back because of the metal shims) So has anybody taken one of these valves apart to better see the valve. There are 4 bolts that run through the electric connection & through the valve body and into the mounting block which is also where the pipe to the intake bolts?

EGR valve ,

Did you clean the exhaust manifold channel that starts at the edge of the exhaust manifold, and goes up to the EGR intake hole? its part of the EGR system. if EGR was blocked up more than likely the EGR / Exhaust manifold channel will have heavy carbon deposits as well. I Used gasket remover and various other aerosols, scrapers and then blew the channel out with compressed air. Some of it is baked on hard.

i stuck my $5 USB china camera up there, used my laptop, and got the all clear . Only because i had one. Dont need that crap.

As mentioned the channels look clear of any build up. I split the valve easy enough and could inspect the valve itself better. Nice and smooth operation with no carbon build up. I then checked the solenoids resistance IAW the details in the manual Each one was 24 Ohms so that was good. As the light comes on very intermittingly I think the cause might be a electric gremlin as opposed to a mechanical type problem.

keep us posted Mick, maybe its the wiring at the connector is the culprit?

Will do. I did inspect the plug as is but did not want to strip it down. There are a few components in the emission system that interface so I think I will disconnect/reconnect each one just in case one of those is the culprit.
