I have absolutely no experience with the Deutz engines, but I might try replacing the temp sender with a temperature sender_guage to verify what the stable temperature is when running under a full load. This is to establish a baseline that the engine is running at the correct temperature. Then work your way back. Depending on the type of sender the engine came with stock, you should be able to check it with a DVM. After that, have the idiot light cluster checked out by an AGCO rep. Other than that, I'm not sure what else could be wrong if your sure the sender wire is okay. Good luck.
