First issue with the Genesis today :-(

[MT-Genesis]

Ah, the electric trunk and multiplexed wiring.
I scored a complete fog light system on Ebay late last year and finally got around to installing it a few days ago. Unhooked the battery, removed air bag from steering wheel, removed steering wheel, disassembled column as to get to turn signal stalk and replace with OEM stalks with fog light switch, put everything back together and the fog light indicator on the dashboard display did work when I turned on the fog switch. Everything worked except the electric trunk.
Thursday, I put the car up on the hoist and proceeded to install the fog light assemblies. When I got to the part of installing the new harness for the fogs, I realized that the wires for the fogs were not in the car side connector so consequently there was going to be no wires to supply power the fogs. At that point, I accepted that the later builds of the car did not have the required wiring.
So back to work and removed the wheel again and put the original stalk back on. What do you know, the electric trunk works again. Looks like a switch and relay is going to be required to make fog lights light up.

Or you can just wire them to one of the accessory terminals on the fuse block and call it done.

How does carbon build up on the throttle body when the fuel is directly injected into the cylinders? Sounds like a pure money maker for the dealer to me.

carbon/oil blow-by is a major concern, specifically in Direct Injection engines. Typically the carbon build up issues are found on the intake valves where in port injection, the valves were washed by the fuel. On Direct Injection, they no longer get fuel washing over them, so any oil and deposit build up has nothing to stop it from building up to a detrimental effect. As for the throttle body, a lot of engines have a PCV tube that is routed into the intake tract prior to the throttle body. I don't think I've ever seen an engine where major carbon build up was a problem on the throttle body, it's usually just a grimy oil build up on the throttle body. Either way, the design of a DI engine is the CAUSE of major build up, so I don't know why you specifically site the function of the DI setup to counter the argument?

And also, as someone who has done manual carbon cleanings on DI engines, I can say it's not smoke and mirrors. The prices they charge for the amount of work it actually takes is a total joke, but the problem is a real thing.

This thread got off a bit on a tangent. So was the valet button the issue? Or is your trunk still jacked?

I tried to un-hijack this thread, but I think it was in vain.
