Why would they bother "monitoring", the car is ancient by Japanese standards and out or warranty by a very very long time. The remote on our new Forester is completely different to the Impreza remote so maybe they redesigned them recently. Daryl

However, if the problem is of that nature, then the manufacturing solution is obvious, and should long ago have become the standard. Sylvia.

I meant monitoring in the sense of checking that what the suppliers were providing would perform the task properly. Sylvia.

But how many people can or know how to solder anything some have major problems just replacing a battery(yet they seem to be able to continue breathing) Kev |
