Problems starting a 2013 Ford Focus: weak battery and warning light

Weak battery when starting the engine

Warning light in the speedometer of the vehicle

Car won't start

Dim or flickering lights

Hey guys, I have a problem with my 2013 Ford Focus, petrol, it won't start, the battery is low on start up, the lights are flickering or dimming and a warning light in the speedo is illuminated. I have a suspicion that there is a message fault. Has anyone had similar experiences or ideas on how to solve the problem? How did you get it sorted out in the workshop? I am grateful for any tips!

Hey, I once had a similar situation with my 2011 Ford Fiesta. I'm not a novice when it comes to cars, but I'm not an expert either, let's just say I have a bit of experience. The symptoms you describe had also sent me to my garage. And after some tests and troubleshooting, it turned out that the control unit was defective and sending wrong signals to the BUS system. It cost 1000 euros, but after that everything worked perfectly again. Can you provide more information about your vehicle? Mileage, has it recently had a service? This could be helpful in providing you with more detailed information.

Hi, my Focus has already done 142365 km and the last service was recently, but that hasn't changed anything. What you mentioned about the control unit makes sense. Will probably need a trip to the garage. Thanks for the tip!

No problem, always happy to help! Yes, it seems that you can't avoid a visit to the workshop. With over 140,000 km, it's easy for something to break, especially when the warning lights come on. I would recommend that you don't wait too long before visiting the workshop to avoid further possible damage. Maybe it really is the control unit, but it's better to have a specialist look at it. Let me know what you find out, I'm really interested. Good luck, buddy!

Thanks, I really appreciate your help! I actually wanted to avoid going to the garage, but I think you're right. With the high mileage, something is bound to break at some point and I don't want to risk it getting any worse. Well, it looks like it's going to be expensive fun. I'll let you know when I know more. Thanks again and see you then!

It sounds like your vehicle might be experiencing an issue with the AC compressor. When the AC is turned on, the compressor puts additional load on the engine. If there's a problem with the compressor, it could cause the engine to stall, especially during start-up. I recommend having a mechanic inspect the AC system to confirm this.

My radiator fan isn't working, it's been a few days now and I've noticed that it doesn't turn on, I've realized this because my air conditioning doesn't work very well, what should I do?

Firstly, check the fuse for the radiator fan, it could be blown. If the fuse is fine, then the issue could be with the fan relay, the temperature sensor, or the fan motor itself. It's best to have a mechanic inspect these components to identify the exact issue. Remember, a non-functioning radiator fan can cause your engine to overheat, which is a serious issue.
