P0597 - look at the rear of the thermostat housing and there's a two-pin plug kind of pointing down and towards the bulkhead. That's the thermostat heater connector. See if it's corroded.

Cheers Equinox i found the 2 pin plug but cant see how it releases to remove plug,when i get it out if it isnt corroded does that mean i would have to buy the complete thermostat housing to replace the switch if its faulty.
thanks for your help

before going any further remove a battery lead and pull main plugs fron ecu and fusebox, check for any water or corrosion.
the o2 sensor is the top and more expensive one so rule out a short first.

have taken apart a thermostat heater before and its just a heating element so guess you can do a resistance check on that.

Engine compartment is full of very similar plugs. For the best clue have a look at the connector on the Exhaust Electrovalve. its at the front of the engine, on the left as you're looking at it, just below the rocker cover, pointing towards the front of the car.

To remove the connector you gently prise upwards on a locking tab with a small screwdriver. Figure out how it works on the electrovalve then try the thermostat heater - but this time the bloody locking tab is UNDERNEATH!!!

Have fun
