I have thoroughly investigated the fault i have had within the 400V controller resulting in Error 276 and ive found the following failed components inside. 1) Mosfet TR3 IXUS IXFL100N50P failed RS Components 2) Resistor R3 Cracked 68 OHM ordered Farnell 3) IC1 MCP6031E Shorting to ground...

Am i right in saying the recharge RC circuit relies upon the resistor inside the 400V controller? looking at the controller the large metal film resistor inside appears to be part of the circuit the car needs to decide to start or not. ie, if this resistor fails then the error triggers and it...

great advice, do you have the part numbers for the gold plated versions you suggested?

yes it appears my roadster is also having the same issue. I have removed the controller and disassembled it. The MOSFET had blown so i replaced it, however after replacing the controller in the car im still getting the same fault code when i try to start the car. The cabin fan doesn't appear...

Do you know what controller failed? any additional info? is it the one located under the front that also controls the heating? Did it take out the battery fuse? was there still coolant pumps running when it had the fault?
