EPC light, multiple short to ground codes

[RiverRS4]

Hello everyone!

About a week and a half ago I was making a trip home from errands and the EPC light came on. Bascially went into limp mode, only wouldnt accelerate and has a lumpy idle with surging. Dug into the ECU compartment after looking through the fuse panel in the car with nothing out of the ordinary. 15A fuse blew above the relays next to the ECU. Replaced it with a new one, started it up, ran fine with no light, the once I took it down the road, accelerated a little bit, the light came right back on with the same symptoms, so that fuse has popped now as well. I considered a short potentially like a bare wire, but my driveway is extremely bumpy, so if that were the case, the light would have been on a lot sooner than when running down the road. Or even when at startup.

Regardless, I need some help figuring this one out. Here are the codes -

01112 - EVAP purge control valve (N80) short to ground P0456
04199 - Intake Air Switch (N335) short to ground P0167
06173 - Seconday AIR pump relay (J299) short to ground
08552 - Fuel Pressure Regulator valve (N276) open circuit P2294 no signal
05170 - Secondary Air Injection Solenoid Valve (N112) open circuit P1432 no signal
09217 - EVAP leak detection pump control circuit no signal P2401
00048 - Oxygen Sensor B1 S1 open circuit/no signal P0030

I know these codes are in relation to the fuse being out, but I’m wondering if anyone has some insight on where to look or an idea of it something needs replaced? Symptoms are weird and don’t seem to be a short/bare wire somewhere. Any help is greatly appreciated!!

Thank you!

Hi mate any updates on your problems

Not yet unfortunately, I have been researching and digging through the car for any possible bare wires/bad sensors, but nothing yet. Car has sat for over a month now.

Where are you based?
Might be best to get the car trailered to a specialist?
