I agree on your 'some cause problems, some don't' this is even confirmed by Lotus themselves, who don't know what causes the problems.
In fact, some cause problems using the original airbox!!!

Did the dealer tell you exactly which error message was on the MIL testing gadget?
And did the system you had on your car had the red nose cone?
