S300 and ECU in limp home mode all of a sudden. S300 has red led on solid as soon as I switch the ignition to "on". ECU works fine with another S300. Bad S300 does the same thing in another ECU.
If I erase the ECU, it says "erase unsuccessful" but the red led goes out and it works until I turn off the car. Same thing repeats as if it cannot hold a calibration in memory.
S300 won't hold a calibration

Re: S300 won't hold a calibration
It sounds like the internal battery has died. Since we cannot replace this you will need to upgrade to the newest s300 V3. The price for this is $380 from a non-working s300.
Re: S300 won't hold a calibration
Do I buy direct? $380 plus shipping plus I have to retyrn my bad S300?

Good morning Spunkster, I posted a couple of follow-up questions. Please let me know how to proceed

It is $100 more for an s300 that is not in working order.
