		Don't worry dude, these TUs like to run nice and warm.
My 1.6 runs are 95-97 as standard and has done for 2/3 years

		What size is it? If its a 1.6, it's a TU. if its a 1.8 or 2.0, it's a XU. also, if its 16 valve in a 306, it's definately a XU. All 306 diesels were XU but only 8v. 
The only 16v TU They did was the 106 gti which was a 1.6

		They generally do wander up and down the temp scale in hot weather - they don't hold much oil or water so the temperatures change fairly quickly in traffic or under load.
