Some cars have problems in winter Reliable to start. This is of course annoying when you are on your way to work or to an appointment. And at the same time, other people's vehicles seem to have no problems at all with the winter. Can someone give you start Help give, then you might still be leaving on time. But this helpful contact is often missing and, of course, it is annoying on top of that. If the car causes problems in winter and won't start in the morning, it can several causes to have. If the engine does not start, check the following things. For one, a Engine oil that is too viscous be the cause, but also one weak battery.
Starting problem due to engine oil
According to the German press agency, TÜV Nord recommends a motor oil for the winter with low viscosity. A high viscosity motor oil is relatively thick. In freezing weather, the engine often has problems starting up. The starter cannot handle the viscous oil, as the effort required to start the engine is significantly increased. That is why TÜV Nord recommends an oil with a low viscosity in the range of 0W30 to 0W40 for the whole year.
Starting problem due to low battery
Batteries that have been in use for several years can become weak. Therefore check the battery before winter. The batteries are sometimes significantly less efficient, especially in sub-zero temperatures. The alternator consumes a lot of electricity when it is started. The battery must be efficient for this. If your car won't start, it can have one weak battery lie. To get the engine to start, you may need help jump-starting or try the car to roll up. In addition, when the engine is running again, you have to eat up electricity such as the Heated seats, a Rear window heating, the Air conditioning, Light and Radio turn off.
This is the only way to fully recharge the battery via the alternator. And avoid short journeys, as the battery cannot fully charge here. Depending on the vehicle type, a battery only charges after a distance of at least 10 kilometers completely up again. You can get the battery expertly in the form of one before winter Winter check check leave or maybe just reload yourself. Also can a battery monitor help to identify a weakening battery ahead of time.
Does the car generally not start? Or are there only starting problems in winter? The information summarized:
- The following problems can cause a car not to start:
- and the Ignition lock is defective
- can Fuel Lines is leaking
- of Fuel Filter is blocked
- can glow plugs are broken
- the glow plug control unit is defective
- can ignition coil is defective
- and the Engine control unit is defective
- a engine failure is available
- of AdBlue-Tank is empty
- of Fuel tank is empty
- so that In order for the engine to function properly, it needs fuel, electricity & air (If something doesn't work, it's usually due to one of these three points)
- Important: is the problem continuous or only isolated / sporadic available?
- other causes if the car does not start
- car battery empty (does the starter turn?)
– do the lighting or other electrical consumers have interruptions? - If the battery is to blame for the problem, there can be various causes:
– Battery too weak due to age
– Battery not charged correctly recently, because there is a problem with the generator?
– Battery "deeply discharged" and therefore defective?
– the cause of any charging problems must be eliminated - Simply check the battery yourself
– using a voltage tester for the cigarette lighter
– using a multimeter
– Less than 12 volts are critical
– Start from the car using start Help is normally possible (with another vehicle or with a mobile battery) - Is the starter defective?
– Starter or magnetic switch defective, then the engine cannot be started
– no start using Jump start possible? Then the problem is rarely with the battery, but perhaps with the defective starter.
- A starter can often also be repaired - Cars with a manual transmission can get through if necessary Push to be started
- sensor defect
– such as a defective crankshaft sensor or a defective coolant sensor (a message should be stored in the error memory) - fuel pump is defect
– A defective fuel pump or high-pressure pump does not deliver any fuel to the engine
– A blown fuse or a faulty fuel pump relay can also cause the problem - Marten bite
– Ignition cables are often bitten through by martens (Direct damage caused by martens is usually covered by car insurance) - Diesel filter clogged / frozen
– if it is too cold, the diesel fuel can form paraffin crystals and clog the system (also referred to as "slurring".)
– so-called “winter diesel” keeps down to -20 °C or special additives can also help
