I'm out of warranty and this is definitely my symptom. I called Lotus USA, with the TSB, they said "as a class 3 TSB it's repaired only on a customer's complaint under warranty, if the complaint is after the warranty expired, it is the client's bill."
Well this sucks!
Any good sources for the part cheap? Seems a fairly straight forward swap. Any help is appreciated, your write up seems to cover most of it though.
