![]() Hi, I have a 2003 sl350, the car has an overheating issue. Joined 2023 Add to quote Only show this user 1.If you haven't been babying your cars until they reach operating temp thus far, there's zero reason to start with this car just because it has a light instead of a full gauge (obviously full throttle from a stop maybe isn't the best practice until things get warmed up, but that seems like common sense).Īnd obviously, if the other indicator light comes on (a red one I think) then you're running hot for some reason, then may be a good time to head to the shop.

The light goes off after a couple of minutes (obvious this will vary in time depending on how warm it is outside). even the 10th gens which have a normal temp gauge start with zero bars on start up. However, a radiator fan may also turn on and off to signal that there’s something wrong with your vehicle. A low coolant level can be due to a leak in the system, which should be addressed immediately. The coolant or antifreeze is responsible for maintaining the engine's temperature and preventing it from overheating. They turn on to cool your car and off once the temperature is at the lowest possible level. When the coolant warning light is on, one of the most common causes is a low coolant level. An engine, at normal operating temp is way hotter than the ambient air temp, so even on a hot summer day, the engine isn't going to start up warm enough to already be normal operating temp. A radiator fan goes on and off to maintain optimum temperatures. This indicator light is completely normal. However, if your VW actually overheats, it could be due to several reasons. ![]() It could be due to sensor issues or wiring problems, which prevent you from accurately monitoring the engine’s temperature. This may seem like a DIY job, but it is actually a very complex repair to tackle. If you notice your Volkswagen Tiguan Coolant Light Flashing, it may not necessarily mean that the engine is too hot. ![]() ![]() When the low coolant sensor goes bad you could have a perfectly operable tank and no leaks, just a bad sensor or light that will illuminate due to a bad reading. Some of ya'll never drove a 9th gen and it shows, lol. One of the last remaining things you can check is the coolant temp sensor and if it has gone bad.
