Better go to dealer and ask them to order based on your VIN. You know it will be right for the car and may have been superceded.

They do fail after about 15 years

I replaced mine about 5 years ago with one from ebay cost £15.00, there are dozens available, just make sure it is the same part number and you will have no problems, apply silicon grease around the connector
