Fristly Welcome.

Check the wire that rans from the bottom to the back of the seat as they do brake. And that the wire under the seat.

Check the idle control valve, give it a good clean or replace it.

Last one sorry have not got a clue.

when you turn the steering or put a lot of electrics on the load will slow the engine at idle. The computer senses it as the extra load is placed on the engine, the car will try and raise the engine revs a bit to give more power, the idle control valve is playing up so it cant do this properly, the lack of power in your battery is causing the gauges to drop as you turn the steering, also revs droping may cause oil pressure to drop, try replacing your battery if it goes ok then starts playing up again check the alternator, if not it was the battery, but clean or fit a new idle control valve then the revs will change correctly as well

Heated Seats.

Use a multimeter and check the resistance of the heater pads. If it is open circuit it's broke.
If it's ok Check for voltage at seat. If no volts at seat check relay is operating.
If relay is operating but seats don't work change the relay.
If the relay is not operating change the switch.
If you have any probs mate drop us a pivate message and i can help you out with your electrics.
