Does anyone know if it is physically easy to fit the electric heating element in to a Mk3 Octavia? According to Skoda, it can't be retrofitted, it can only be done at the factory. However, suppose your element broke, it has to be removable or replacable. So I figured if it's easy to get to, I could just take a 100amp feed direct to the battery via a switched relay and mount a switch somewhere. Not a "proper" retrofit, but better than nothing. Anyone any ideas? Or even better still, anyon
