Temperature Warning Light on 2002 Volkswagen GTI

My temp. warning light appears as soon as I start my car. I have let car idle for 2 minutes then turned it off. I start car again, & warning light is off.NO PROBLEM, RIGHT ? Wrong !!! The oil & coolant fluids are correct, but after driving for 5 min. The engine is giving off a strong burning smell.Temp is correct, no high reading...WHAT CAN IT BE...?

Replace the coolant temp sensor first as they are known to have a lot of problems (the sensor has 2 circuits, 1 is for the gauge and the other is for the ECM). The burning smell is probably engine oil on the exhaust manifold or turbo from leaking valve cover gasket, cam seals, or cam chain tensioner gaskets (also common problems). Make sure you replace all of the timing components and water pump by 100k. This is a great time to re-seal the cams also. Good luck. James

Thankyou for your generous info, & sorry, I have'nt been on here to read your diagnostic suggestion. Just this past weekend, my GTI over-heated, & I had to replace 2 plastic coolant hose connectors. The main problem was this, The cooling fan had a kink in the wiring<& would go on when it felt like it, thus leading to that burning over-heating smell I would notice once & a while. My problem was totally fixed today & I once again THANK YOU for showing a concern...
