Yes indeed Dave! shame its your wallet that's paying BHM to become the experts though. I really am starting to wonder just exactly what is accessible via the OBD2 port. As I said little is available to me on my Duratec 2010 car. yes you can clear fault codes but so can the most rudimentary readers. and any fault codes I have had which have been almost negligible I have induced myself from disconnects or component changes. When I first got the car the OBD2 port was nowhere to be seen, I eventually found it tucked way up out of the way and unless I hadn't removed the dash it was ..... er! Hidden? I wonder if Morgan had just removed the power lead connection from the block on these locked cars. Anyway Dave, I think you probably were closer than you think to solving this one. Had you had someone like RichardV6 looking at the car together with you I'll bet you would have found it.

Good news it's sorted Dave, I assume a spare MAF will be added to the Scottish tours kit
Out of interest, did you ask BHM if they could unlock the OBD2 port for your own future access ?

That is not a question for an open Forum maybe Jon

I didn't ask. Given that there were no fault codes when it failed the MOT with the AR upgrade, where both CO and HC was more than double the maximum limit, I really don't see the point. It's almost as if the ECU is blind to faults, and just alters fuel pressure as a consequence of the MAF input. It will remain a paradox.
It's tempting to get a spare MAF, but it's such a rare occurence. I had the Roadster run a bit unevenly a few years ago, and a squirt of MAF cleaner sorted it. That's the usual routine. This is another reason why I don't really worship oiled filters like K&N, because there's a risk of oil droplets contaminating the MAF sensor.

I picked one up a few years ago but have never fitted it. They aren't expensive but my reasoning was that with a 2007 engine they might become unavailable in the future. Even now they are only around £90 on eBay. Yesterday I did decide to have a look at mine and gave it a good squirt of sensor cleaner. I do have an oiled K&N filter but I rarely re-oil it and have never had a problem with contamination.

Ditto re the K&N slab filter on my Roadster. Cleaned MAF sensor twice now always catching the drips of dedicated cleaner onto white tissue. Absolutely clear though as was our Mini's. I guess there is an opportunity to over oil the element but the instructions clearly say just enough of the red oil to show as a uniform covering on the filter material after washing it.

In answer to are all GDIs locked out the answer is no. I had one of the first GDIs from new, a 2014 car, that used to regularly display the engine warning light when applying full throttle after a lengthy time at low revs. So stuck in traffic and finally having an overtaking opportunity I could almost guarantee the light would appear. I used to carry an OBD reader with me so I could clear it when I stopped. No idea if Morgan locked later cars. I don't suppose you can remember the fault code Andrew  . At a guess maybe O2 sensor 1 although engine would be in open loop under such conditions.

As I have previously mentioned I do follow a young lady on You Tube as she m/cycles solo around the world, and into all sorts of road and off road conditions from jungles to deserts and everything in between..... For her current escapade through the Stans, China, and across Mongolia, deserts and all, she chose to ditch modern tec and went back to a pre digital Yamaha in the hope of increased reliability by way of fewer things to go wrong....which overall seems to have worked out rather well, if interested you might like to beam up Itchy boots to get an idea of what she is about...?

So we are all seeking our MAF sensor now, just in case…but it looks like the standard 2.0 Duratec engine that preceded the GDI does not use a MAF but instead has a MAP sensor down on the inlet manifold. This measures pressure and though not quite so accurate as a MAF, requires virtually no maintenance.

If that early GDI was throwing an EML at the drop of a hat, that does suggest that MMC 'fixed' it.
