[QUOTE="lass 18, post: 114922, member: 1494"] Just heard from a mech 2day. The coolant sensor could be the culprit. Was with a mech 2day 2 replace tensioner bearing. The mech noticed coolant residue on the expansion tank and when checked discovered valve broken. Advised changing the expansion tank as this could result in engine overheating. He also replaced the coolant sensor as the sensor was cracked at a few locations (I presume due to heat) and informed me not to be surprised if coolant warning light activates intermittently even after replacing the damaged sensor with a new sensor. It seems that this is quite a common problem with the e36. Not sure about the e46 though. The price 4 the coolant sensor the workshop charged me was RM75 (excluding labor). The workshop bought the coolant sensor from Bavarian Auto. Saw a delivery boy in Bavarian Auto T Shirt delivering the sensor. [/QUOTE]
