It’s me again with another problem (face palm) So I’ve had my stagea for around 8 months now, pretty much from since I’ve had it the 4WD Light has been on and off intermittently. Last scan said “pressure sw [on failure]” not sure which ecu they scanned but I didn’t muck around and ordered an after market pressure switch from Frenchies Performance Garage had it installed with my manual conversion. 4WD light was still there, mechanic told me they bled the system and it still wouldn’t work and they think power is not going to the pump or something… so I took it for another scan at my local and they said there was no error code just gearbox code so I’m assuming they scanned the main ecu and not the attessa ecu, but did say the 4wd light was gone. But like I said it’s intermittent, it came back after a long drive. So any ideas what I can do next i really want to get the car on the dyno this month.
I’ve also tried pumping all tyres equally as front left was low pressure and still, 4wd light is intermittently active. Also the atessa fluid is always at the max line doesn’t change when car is on or after a drive.
Car also has a slight ringing noise towards the rear wheels on either side that doesn’t change in volume or pattern it’s just a constant ring, I don’t know for sure if it comes on when 4wd light is on but the noise is also intermittent. (If that helps)
Car is in the shop getting parts installed so I can’t do much at the moment but hoping for some ideas.
This was the first scan error code not sure which ECU
