Default Deleted N249 Throwing Codes

A couple months ago I bought a stg3 S4 Avant, it ran strong and boosted to 23 psi. 2 weeks ago I was driving home and the car bucked and went into limp mode, after cycling the ignition I was able to drive again but only could get 20psi. This works for a little while but it eventually goes back to limp mode and only gives me 6psi. I have an air/fuel gauge and before everything it was pretty constant somewhere around 14/15, now while stopped or idling it drops down to 10 and sometimes up to 16/17. Driving brings this back to inline to what I understand is a good afr, just no boost.

I had the car scanned via vagcom last week and the codes called out the N249, which has been deleted along with the pcv. The valve is gone and no resistor so I believe it's been coded out. Right now all I have are the fault codes but I just purchased a vagcom so once I find a laptop I can provide more information.

Any ideas?

If it's an open circuit, it knows it's not plugged in. I don't think it's been coded out.

You can get resistor from urotuning like this one SAI_Resistor_Square SAI Delete Resistor, Square Connector
