Dash lit up like a Christmas tree, all errors under the sun. Turned off car, now it won't start. Turns on, but immediately turns off. Immobilizer?

Yes. Keys still lock/unlock the doors.

One thing I just mentioned to him I noticed in the video, is the digital dash doesn't load the milage.

View attachment 233336

Mine does that pretty much instantly the second it kicks on.

Thats not a good sign, I’m not in my car but just having the door open should display the mileage IIRC.

Dash is a lot more expensive/time consuming swap than a start stop switch, but that makes the dash look more suspicious.

So it doesn't do it the moment you open the door on this dash, but it should load up when you press the ignition to turn on the accessory power without turning the car on. I have the same dash (installed at the same time), and that's how mine behaves.

I recommend to him to swap the original unit back in. It's a bit of a pain, but no more than an hour or so of work.

In that case the switch is still my top pick.

The power on functions aren’t matching switch position.

Do you mean the actual physical push to start button/switch itself? That'd be a quick 5 minute swap to try plopping mine in his car that wouldn't hurt to try.

Unless you're talking about the BCM (BCM might not be the right term) that the switch connects to that actually controls those functions once you press the button? That might be a little more challenging...

Yeah the push to start switch itself

Almost has to be the display.

This is such a weird issue I can't get behind "Almost has to be..." for any suggestion. But also wouldn't rule anything (that hasn't been tried yet) out.

It's just a very inconvenient time. I think he plans on trying to put the original dash back in, but just tough finding the time 3 days before Christmas.

Fuel pump still primes when i open the door.
Going to try the cluster swap back to OEM and see how that goes.

Push button not matching positioning is a possibility but less likley given how the whole thing first manifested itself in the middle of my commute to work this morning. Car was driving normally, no limp mode or anything like that. Codes you see in the video popped while i was driving and the radio shut off (still turns on just fine now) but the radio does say that in order to make any changes in the car settings page that the ignition has to be on - and no matter the sequence of of push to start pushes with and without clutch depressed, it continues to report the ignition as not on.

The dash shouldn’t have any control over the radio turning off and on, or the car cranking but not starting.

Rule out the push to start switch before you dive into taking the dash out.

Update - He went down to try to fiddle with the push button start like @GTI Jake was talking about.

Car randomly started fine, no issues. Drove it around, drives fine.

Got back home, did an OBD11 scan with the car running. Bunch of databus errors.

Cleared codes, everything looks fine. Turned it off and back on again fine.

Scan results below.
