While I'm waiting for my verification status to clear, I'm hoping someone can help me.

Around town my car has no apparent issues, but once I get out town (speeds >80kph or 50mph) and take a gentle left-hand turns the engine cuts out and the engine light flashes. Once the corner has finished, the car returns to normal. Sometimes the light clears itself and sometimes it doesn't.

I've cleared the DTCs and replicated this behavior again once and here's the VCDS code. Is this more likely an ECM short or a yaw sensor issue?

Any help is greatly appreciated. Thanks in advance.

Kia Ora Bro :D

Do the dash lights etc cut off when it cuts out? (as if the key was turned off). Have you tried removing all other keys from the ignition key?

It's strange that the engine light comes on/stays on... but there are no codes in the Engine ECU.

Since it's got a full Kessy system, I doubt he's got any weight hanging from the ignition switch at all. ;)

Yeah, but "No comms with ECU" faults in several other control modules. I'd speculate something breaks a circuit when loaded with the right G-forces. Might wanna let the vehicle idle and apply sideways forces on things like relays and any harness sections that are at all floppy to see if any of that gets it to cut out.

W00t, I'm now verified.

Thanks for the suggestions. The key stays in my pocket, so there is no weight on the ignition system. All other dash lights are unaffected.

What's perplexing to me is that I can't replicate the behavior under 50mph. But as soon as I reach that point, it's quite easy to do. It may also be coincidental, but this seems to be more pronounced with a full fuel tank.
