Options for out-of-warranty Combination Meter

Some of you may have already seen my thread about ending up on just the wrong side of the extended warranty on the combination meter. I've just been continuing to drive and it's worked 99% of the time, but it's starting to fail more often and in milder temperatures now, so I'd like to fix it.

Option 1 is of course dealer repair, meaning full price and possibly an open-ended timeframe during which I'd be driving a rental on my own dime.

I looked into Luscious Garage but was disappointed to learn they no longer facilitate repairs of the combo meters. But something I read somewhere alluded to the possibility that they could offer the same service as a dealership, removing the old meter, sending it in, and receiving the properly-programmed meter and installing it. Does anyone know if that's the case?

If it's true, I'm thinking I could engage them (or another shop if I can find one) to order my replacement meter. Depending on how difficult it is to access, I could remove it, ship it off, and wait for the new meter to come back. I liked their policy of providing loaner CMs while waiting for the turnaround.

I was told the dealer won't allow the car to be driven while the meter is out - to avoid charges of facilitating odometer fraud - but I don't know if that's true, or if forces would conspire to prevent me from driving the car meterless. I'd rather put a loaner in so I can drive normally until my meter comes back, if I can procure one.

On a related note, I've noticed my speedometer reads about 1.5-2% higher than actual speed. Does that mean my odometer reading is similarly skewed high? I've been loathe to drive any distance with the CM not working because I didn't want my ODO to be off, but if it's already reading high due to the speed inaccuracy, I figure I've actually got about 2,000-3,000 miles where I'll be bringing my car's ODO closer to *actual* driven mileage. If that's the case I won't sweat it if I have to drive for a week or two without my CM.
