the rear bank is bank1 and the sensor is on the intake side of the head. It is mounted on the back head but between the two heads next to the air box

There's a website that has all this information about all this and manuals everything totally free there are many actually but I personally like few . . let me know if u need help thanks

Remove the internal handle and I think 1 or 2 screws and lift inside door panel off, pull the latch and it will open!!

check the electrical harness , and wires

take it to the work shop

I assume its a petrol version ,,Now first thing is check out O2 sensors with a voltmeter ,undo plug in turn and check for 12v feed with ignition on ,this will be two wires the same colour normally white ,now check for continuety on the sensor end of the plug .Now if this checks then reconnect the plug using a small pin push through the wire to gain contact and start engine and check voltages ,should run between 0.120 to 750 as engine is revved .if no reading or it stays the same normally around 700 then renew .Use universal ones around 50euros each These must be working correctly or the symptoms are exactly as you describe .You cannot remove the catalyitic converters as this means the vehicle will be poluting the atmosphere also it will not pass the annual vehicle inspection .Also yes the throttle position can cause similar problems plus a few other things as well .If you are not capable of this sort of work then use a local mechanic to check it out for you.

possible abs actuator issue....need to pull codes to know for sure

Until the fault is fixed it won't stay reset. Once the fault is fixed it should go off on its own

Is the accelerator cable damaged, or does the engine have a vac leak ? Either the throttle plate is open or there is a vac leak allowing air to enter the intake manifold.

For water leaking inside the rear door panel, I'll suggest you check and replace the black rubber/foamy seal that is part of the high-mounted-rear light assembly. It gets weak over time and soaks water, thereby allowing water seep into the booth lining and also into the underlay of the carpet. If you have a cracked rear-light (the one attached to the boot hatch), you may also get a leak. Change this rubber seal/ gasket. I used an old rubber carpet to make a gasket to fit the light assembly, and it stopped the leakage. Hope this helps.

If silicon is working,I would go with it,silicone last a long time and it's working.

Check rad/coolent fluid level
