Default New JB4 install, Couple of errors/intermittent issues... - 06-11-2020, 10:49 PM


Have just installed a new JB4, with Pinned power Bluetooth module from Autoinstruct.

First run of the car - car was running quite rugged, and no boost. All of the warning lights on the dash went away after a moment of driving except for the 'EPC' light. Limped the car back home.Scanned for codes : 431A, 3B11, 0000

Parked the car & left it off for 30mins , started back up, and it was running fine, EPC light now off - really impressed with how strong it felt.

Put the engine cover back on, and took it for another drive. Went back into a rugged/ struggling to get to revs/speed mode.
Quick scan showed errors : 431A, 3B11, 0000

Took the engine cover back off, let the car for an hour, took it for a another drive, and it was fine again (EPC light off). Has been fine for the last 40km's of driving. Very fun!

But 20 mins into a drive just before, the EPC light came back on, and car went back into a struggling / stuttering on take off mode! Read error codes: 3Ae2, 431A, 0000, 6500, 2000.

Left the car off for half hour by the road,Turned it back on, and the light went away/driving well again. Cleared the codes, all codes are gone, and the car is driving well.

Am concerned i'm going to have this happen when in traffic again. Any advice? is this irregular ? Cheers.
