Hi all,
First off, I'm new on this forum so please don't crucify me for doing something stupid.
I have a 2014 Leon that has been acting up for about six months, the problems started with the start-stop system malfunctioning sometimes (wouldn't stop at red lights). That has now stopped working altogether (Start-stop error "Power consumption too high"): the car won't start using the key, but it will start on neutral by switching ignition on and then pressing the clutch. I have also noticed that the brake lights are sometimes always on, even though the brake pedal isn't pressed. The newest addition is the absence of cruise control.
At first I thought the Start-stop problems were due to a bad battery or a faulty neutral position sensor, but after reading the fault code memory through OBD I had to rethink my theories.
The fault codes are something along these lines (translated on the fly):
-Particulate filter pressure difference sensor cyl. row 1 (Unlogical signal)
-Fuel injection controller control "PEM" (ground fault)
-Brake light sensor (ground fault)
-Glow controller (fault in the circuit)
-Fuel cut-off valve (breakage)
-Fuel pressure control valve (breakage)
-Ignition switch circuit (short-circuit, positive wire)
-Fuel pressure control valve (ground fault)
-Airbag controller (Unlogical signal)
-Front airbag collision sensor, driver side (Unlogical signal)
My question to all of you mk3 owners would be that, have you had any similar problems (or error codes) to these and could all of these problems be the result of the brake pedal sensor wire ground-fault? I can't believe that the car could have had so many part breakdowns on different systems.
Also if anyone can provide me with a wiring diagram that shows how the ignition switch and the brake pad sensor are connected together, it would be greatly appreciated.
