Do the same thing on the positive terminal.
Now, wait a few minutes for the computer to reset.
Finally, reattach the clamps to the terminals and tighten them up.
The procedure in resetting the ECU may vary depending on the year, make, and model of your vehicle. The above suggestion is just a generic guide.

What could be the problem why VW won’t start after changing the battery?
There are different reasons why a Volkswagen may not start after a battery change. One of the most common reasons is that the computer has not been reset properly, as mentioned above.
The other possibility is that the alternator was not properly disconnected before changing the battery. This will cause problems with the charging system and can damage other electrical components in the car.
A faulty battery cable can also be a reason why VW won’t start after a battery change. If this is the case, it’s best to take your vehicle to a mechanic to have it checked out.
Another reason is a malfunctioning immobilizer. The immobilizer is a system that prevents the car from being started without the correct key, mostly known as the electronic security device installed in your VW. To reset the immobilizer, you can either bring your VW to an authorized car dealer or do some DIY work by disconnecting the battery cables, leaving it disconnected for about 15mins and then reconnecting them.
If you have tried all of the methods mentioned above and your VW still won’t start, then it is most likely that there is a more serious problem with the car. In this case, it would be best to take it to a mechanic for further diagnosis and repair.
How do you reset the computer on a Volkswagen Jetta?
The Volkswagen Jetta is a compact car that was introduced to the market in 1980. It’s now in its fifth generation, and each generation has gotten progressively more upscale and luxurious.
Some of the features that come standard on the latest model (the 2019 Jetta) include heated seats, a 6.5-inch touchscreen display, leatherette seating surfaces, Apple CarPlay/Android Auto integration, and automatic emergency braking. You can also upgrade to features like a panoramic sunroof, lane departure warning system, adaptive cruise control, and keyless start/entry.
A Volkswagen Jetta is equipped with a computer in it. This computer controls many things in the car, including how it starts and how it runs. If you change the battery in your Jetta, you will need to reset the computer so that it can learn about the new battery.

Once you have your scanner plugged in, turn on the ignition, press the power button on the scanner then choose reset. This will reset the computer and allow it to learn about the new battery.
If you don’t have an OBD 2 scanner, there are other diagnostic code readers available. This is a device that plugs into the car’s computer and reads any error codes that might be present.
