Hello Jaruba. I have just joined this forum and have exactly the same problem with my car. So far, the engine coolant bypass valve and it's connector have been replaced but the engine warning light is still on. Did you manage to find a fix for your car ? Any help would be much appreciated !

I dont have leaking pump - level of coolant is still same, so why it looks like that connectors are shortened by liquid ?
