I appreciate this is a response to an old thread, but I've had a similar issue with my def system and my mechanic is suggesting a failed heater element or def pump or both. I've found a supplier for both parts made by Bosch - much cheaper than buying the complete system from Mazda.

Cx7 issue
I found buycarparts.co.uk. Although it's a .co.uk domain address they are based in Berlin and have several other trading names that offer the same parts at differing prices. In the end, my issue turned out to be an electrical glitch that didn't require new mechanical parts.

I discovered it was a broken wire feed to the def pump in the adblue tank causing an intermittent fault. It was an easy fix in the end. I've since sold the car but now I'm left with a brand new adblue injector that was never used!
