200tdi guage running hot.

Hi all, been a while since I was here but I have a problem or 2 that I hope the collective can help with. I have a 110 200tdi, recently had a small car run into my rear crossmember and caused a small amount of damage to the body work. Since the bump, the engine temp gauge now sits at the very far edge of the range just under the black line before the red, normally it would sit at half way. Engine temps are Block 65, Head 55, stat housing 72, top rad hose 42, all temps celcius. So are the engine temps normal and gauge gubbed or is there an issue with the engine.
Cheers
