Mike, I was under the impression that disconnecting the battery would have no effect on the ECU memory, hence the reason why the fault codes can't be cleared using this method.
Carlos,
X2 on what Mike said about Autozone. In my experience, they have read the codes for free, but will not reset them (the guy said for liability reasons). I have heard only a few stories where they have reset the codes.
You can get your own code reader for dead cheap these days. It may be a wise investment. Although it was a bit more expensive, I just picked up a Scangauge II (
http://www.scangauge.com/) for about $170 shipped. I really got it for my other car, but it works with the Rover as well. It will read and clear codes and much more like real time data and gauge display of various systems.
I remember my first winter with my D2. Driving up North in very cold conditions, my SES light went off. I'm trying to remember the code, but I think one of them was something like adaptive value out of range (or something like that). I can look the exact code up later as I saved it using the Rovacom.
The point I'm trying to make, is that my MAF was going bad, and the cold air entering seemed to exaggerate/manifest the problem.
I'm not saying this is your problem (especially since you mentioned in you first post that you recently replaced the MAF), just something to think about.
You don't have a K&N air filter do you?
Peace,
Dan
