Computer Reset. I have a Golf it had a broken motor mount and ended up making this simple fix a lot harder than needed. I got sidetracked and decided to pull the whole intake and clean it. During this time I had my battery disconnected a day or so.
After I put it all back together the thing wont start because the computer reset and it forgot my Key's!! And does this happen every time the battery is disconnected? I was looking around but it seems everyone has a different answer to this problem.
Does anyone know for sure? Does the car start then cut out after a couple of seconds? Does the glow plug light come on when you try to start it? If it's the first one then it's the immo but if it doesn't start at all then it's not, if it cranks but doesn't fire and the glow plug light doesn't come on then it's the relay with stamped on it.
Ya it cranks and then fires runs for about a second then dies. This happened before when i had to get my key re programed. Also the Key light on the dash is flashing. Any Ideas?

Remember Me? Mark Forums Read. Page 1 of 2. Thread Tools.Most Volkswagen vehicles are equipped with an electronic computer system that is linked to the dashboard, that tells drivers when the oil needs to be changed. For these reasons, performing all scheduled and recommended maintenance on your vehicle is imperative to keep it running well so you can avoid the many untimely, inconvenient, and possibly expensive repairs that come from neglect.
Once the oil monitoring system is triggered, the driver knows to schedule an appointment to take the vehicle in for servicing. When the engine is running, the sensors continuously monitor engine oil temperature and calculate the oil level.
Both calculations are sent to the dash panel insert and trigger a service light as necessary. The computer system also tracks the engine miles from the time it was reset, and the service light will trigger after a certain amount of miles add up. The owner has the ability to have the mileage intervals set to reflect the best possible maintenance schedule depending on how the owner uses the vehicle, and under what conditions he or she drives.
Since the oil monitoring system is not algorithm-driven, like other more advanced maintenance reminder systems, it does not take into account the differences between light and extreme driving conditions, load weight, towing or weather conditions, important variables that affect oil life. It is best to speak with a mechanic to help you determine the best maintenance plan for you. Do not hesitate to contact our experienced professionals for advice. Volkswagen recommends two different maintenance schedules based on the type of oil used, as well as certain driving habits and driving conditions illustrated in the graph below:.
This is a general depiction of what a Volkswagen maintenance schedule can look like. Depending on variables, like the vehicle year and model and your specific driving habits and conditions, this information is subject to change for maintenance frequency as well as the maintenance performed:.
Some servicers will neglect to do this, which can lead to premature and unnecessary service light triggers. With only a few simple steps, you can learn how to do it yourself for newer Volkswagen models with one of these methods:.

While the Volkswagen oil monitoring system can be used as a reminder to the driver to have the vehicle serviced, it should be only be used as a guideline regarding how the vehicle is driven and under what driving conditions.
This does not mean Volkswagen drivers should ignore such alerts. Such maintenance tasks should always be performed by a qualified technician. If you have any doubts as to what the Volkswagen maintenance system means or what services your vehicle may need, do not hesitate to contact our experienced professionals for advice.

GuruD7RQT answered 2 years ago. If you installed a new battery and the horn blasts continuously then you have installed the battery backwards!! This is extremely dangerous. Turn the battery around and this will solve the problem.
When the battery is placed correctly, the horn will not turn on. Also note that the replacement of the battery will also trigger other sensors on the dashboard so don't be surprised if other lights come on when you turn your car on.
