Hi,

I've had a garage mount a "DEFA warm up" engine heater to my ZT. However there seems to be a problem. The heater unit shorts itself somehow, after running for a couple of minutes. All the connections are fine and the garage is used to fitting these units in other cars (however not MG's)

As my car is a 1.8T it does have the "to small cooling system".. I wonder if this could have anything to do with the problem.. Sort of the heater running dry when getting hot.

The garage contacted the manufacturer, and the only solution they could come up with was to fit a short extension hose to the cooling system allowing more fluids to remain in the heater element(?!)

Has anyone else had this type of unit installed in their car? I had the system in my old ZR, no probs, warm & snugg...

I've had to replace the unit twice alreaady, going to replace it again this week...

Need to get it fixed as we had our first snow here in Stockholm this week, and there's more to come...

Any ideas?
