Hehe, I was going to suggest it was a bit like HP Laser Printers - a lot of fault codes are "undocumented" - i.e. the manufacturer (errr, now my employers) haven't got a clue...
Nice find Tim. I'll bookmark those.

So I would probably check for contamination from overfuelling of something like that maybe? As a check I looked in a couple of other sites and found this at http://www.landroversonly.com/forums/f39/after-weeks-research-p1316-codes-41140/ Code P1316 Reason: 1. Spark plugs 2. Spark plugs Wires 3. Engine Head Gasket 4. Deformation engine head 5. Clear Exhaust & Intake Valve 6. Valve Stem Seal 7. Water in Cylinder (little) 8. Fuel Injector most Clear with Special Fluid 9. BeCM - worst option 10. Crankshaft Position Sensor I have no idea why MMC or anyone else would have been unable to do this 20 second exercise.

It cost a lot more than £30, but that's by the by. I bought it from Halford's. 'Nuff said. Now, to demonstrate to me that what you say is true, tell me what this fault code means: P.1316; and how I cure the fault. It's one I get often from my 4.0 litre, Land Rover V-8 powered, 2003 +8. If you can tell me, you can also tell the MMC - they don't know, nor do any of the dealers I've taken it to. Nor does the AA. I just cancel the code and carry on as before. Nothing seems to happen except that it occurs again, sooner or later. I gather Rover used to charge about £5 grand for their Testbook set-up. I'm not prepared to spend that on diagnostic equipment.

Sadly, this myth has been well and truly sold to many people, who honestly believe that you can't work with modern cars at home. Routine servicing is much easier than it used to be, spark plugs only have to be changed once in a blue moon, tappets, never need attention, all you really have to do is change the oil and check the fluids - and yet strangely the costs we get charged by the dealer are vastly higher than ever they used to be. Cheapest entry point is 30 quid or so, which buys a code reader with which you can interpret any stored fault codes and clear them (a process which a dealer would charge 70 quid plus for). Plug the reader into the OBDII socket, download the codes, look up what they mean, fix the offending part. Perfect for identifying and cleaning or replacing a dirty MAF sensor or similar. If you want to spend a bit more money, then a couple of hundred quid on a laptop, a copy of the relevant software (e.g. Rovacom for a GEMS +8) and you can furtle to your heart's content, really getting to grips with what your engine's up to. If you want to get properly ambitious, then you can buy a complete replacement ECU from someone like Omex (who supply MMC), Emerald, or MBE, and completely remap and reprogram your entire performance envelope. And if you want to go completely OTT, you can even build you own engine management system from scratch with Megasquirt. I fully understand that messing about with one's engine is not everyone's cup of tea - and fair enough, I wouldn't try to convince anyone to do stuff they don't want to, but I would hate to think there are people out there who think 'I wish I could work on my modern Mog like I used to with my old one". It's a different set of skills, sure, but certainly not beyond an average enthusiast mechanic. I reckon that adjusting one's fuelling map with a laptop is a heck of a lot more straightforward than trying to understand the complexities of twin DCOEs.
