Canon 7D Error Code 01

Help Please!
While on the Isle of Wight, earlier this week, my 7d, sporting an 'L' zoom 24-105 lens, developed an error code 01, reading, coomunication between the camera and lens is faulty. Clean the lens contacts. I thought I tried to clean both contacts of lens and camera body, using a lens cloth, but it's made no difference. I can take photos at the widest setting, but as soon as I zoom, I can't take a photo, and the error message appears.
I visited a Jessops store on the Island, who tried again tried to clean the contacts with a lens cloth, but still the error appeared. They took off my lens and put on their own 50 mm lens, which worked well. I failed to ask them to try a zoom lens.
Now for the rest of the story. While staying at a hotel in Portsmouth, I idiotically failed to realise, that I had left all my photo gear in the boot of my car!
THis of course would cause condensation, I'm assuming.
My question is, have I caused dire faults with my gear?
I thank you in advance, for helping an old codger like me!

your 7d is weather proof so leaving it in the car won't or should not cause any problems.
my 7d has been flooded by sea waves and left over night in the van at times with no effect on anything so to answer the question

No it will not cause faults. or should not.

Hello Friends,
thank you all so much, for your kind replies, I really appreciate it.
Mr. Robinson, your comment really calmed my fears.It's probably a coincidence, that the lens played up when it did.
After posting my question, I checked my other 3 zooms, and they all worked perfectly, which is marvellous! At least there's no problem with the camera. So I can at least carry on using my other lenses as normal.
Once again, thank you for your help in this matter. Once I get home, I shall contact a Canon repairer.
