I have recently had a planar heater installed on my T5.1 underbody. I am aware that it is covered by the underbody plastic tray, I have found a stainless steel box that you can buy to house the heater in to prevent any damage and to protect against rust.
Can anyone tell me if anyone has got one and are they worth the £90.
