Correct valve position for Corsa installation…

[Yo Nadz]

I’ll be installing the Corsa cat back exhaust next week and want to avoid the CEL valve issue I’ve been reading about. Rather than reviving an old thread I figured I’d make a new one in regards to it. Has anyone figured out the correct valve position for install? Disassemble with the valves open or closed? Install in the Corsa with the valves open or closed? How do I avoid this dreaded CEL?

Any insight is appreciated.

Put it into Tour mode, disconnect negative, install. If you throw a valve position code, perform a relearn. Very easy process. Regardless of which mode, if the computer senses an out of range variable it will require a relearn. Might as well just grab a Launch OBD bidirectional tool (unless you have one) and have just in case. If a shop is doing the install, they can do a relearn if need as well.

Are you suggesting the OP buy a $2000 tool?

No, I'm suggesting the OP buy a $129 tool, which has been mentioned MANY times by myself, if he plans on installing the exhaust, to avoid any potential headaches.

I have been trying to do an exhaust relearn but the tool says "not ready" under the learn function for exhaust valve relearn. The valves still function just fine, open and close as they should. Just cannot get rid of that damn CEL. Does anyone know what isn't ready? Or maybe if a dealer or tuning can override it and force readiness for the learn

Around the 1:50 mark they discuss and show the valve install. Doing mine very soon. Corsa also has instructions that go with the exhaust.

This is exactly what I’m trying to avoid.

Corsa’s instructions (at least the ones on their website) don’t mention anything about whether the valves should be open or closed, or what mode to disconnect the battery in. I did find these 2 instructions online, but they contradict each other.

Oh boy, not sure. I think as long as it goes back in the same way it came out the it should be ok?

Doing my install in a week or so.

Let me know how yours goes. I just got an email that my order has a 7 day lead time, so I’ll probably be installing closer to Easter.
