Temperature icon SolvedSolved

Volkswagen Jetta 2004  170000 miles
Hi everyone, this is what happened to me: on Tuesday, the engine was cleaned. On Wednesday, it worked properly. On Thursday, the temperature's icon on the dashboard turned on and, when I opened the hood, I noticed that the antifreeze compartment was not closed correctly and the liquid was coming out of it. That same day I filled the compartment with its corresponding antifreeze, left the car on for a while and the icon turned off. On Friday, the temperature's icon turned on again but, when I checked the antifreeze level, it was between the accepted limits. The car has not overheated lately, the water pump is a year old and the fans are working properly. How can I remove the icon? Or what is it that is failing?

Usually the icon turns on when there is a liquid deficit. In other cases it has to do with the engine still being cold because you have just started the car. The normal thing is that the needle which measures the temperature is right in the middle. If it is above that, it is a problem. Hope this helps.

I had the same problem with my Jeta and the cause was that the terminals that go behind the fuse panel were sulphated, so I cleaned them and it is now working properly. There are two connectors, a yellow and a white one. Hope my comment helps you.

I have a 2019 Volkswagen Jetta 1.4 TSI with an 8-speed automatic transmission.
I have been experiencing a jerking/bumping issue when shifting gears. The main symptoms are:

1. A noticeable jerk when shifting from N to D. 2. A jerk when shifting from 1st to 2nd gear. 3. A jerk when shifting from 2nd to 3rd gear. 4. A jerk when downshifting from 3rd to 2nd gear. 5. Sometimes there is also a jerk when downshifting from 4th gear. 6. The problem has been present for about one year. 7. The transmission fluid has been changed several times, but the problem is still present. 8. Different mechanics have suggested different causes, including the transmission control module, sensors, or internal transmission problems.
I would like a proper diagnosis before replacing the transmission. Please check the transmission control module, solenoids, sensors, adaptation values, line pressure, transmission mounts, and perform a complete scan for transmission-related fault codes.

2007 VW Jetta wagon cranks no firing...

Volkswagen Jetta 2007 Wagon 100000 miles
All Fuses where taken out by my helpful 10yr old son...I have replaced the fuses to the best of my ability. I did this from getting as many similar fuse panel layouts i could fined online. I may have some wrong...

After reinstalling the fuses in both panels A and B on my 2007 VW Jetta wagon. The car would fire up and start then it immediately died after it had fired up. Now it cranks but does not fire at all. Dead... I'm baffled as nothing actually changed to cause the change... Humm please stear me straight. Thx lol
