Good pm. Just want to know if anyone had experienced a problem I experienced tonight with my e30 325i.

This morning, I heard a slight langitngit coming from the engine. The sound is similar to a worn out water pump. (I had a brand new water pump, timing belt and tensioner installed just three weeks ago). This evening, the overheat warning light on the OBD suddenly flashed for a few seconds. The temp guage was normal, a little less than half. Upon reaching my destination, I checked the engine bay and smelled a slight burning odor.

On my way home, the warning lights on the right side of the instrument cluster - hand brake, abs, battery, brake sensors, etc - suddenly illuminated. They remained illumanated till I reached home. Lights and other accessories remained normal and did not decrease in power inspite of the warning lights. Engine power seems normal.

Has anyone experienced a similar problem? What could have gone wrong?

Many thanks in advance.
