20 Most Recent 2008 Volkswagen Jetta Questions & Answers

Truly a ridiculous amount of electronics in this vehicle. Lots of fuses and modules for radiator cooling, but no relay. That means it is a function of the ECM and the 'modules'. https://www.autogenius.info/volkswagen-jetta-2003-2009-fuse-box-diagram/ In earlier models it is located under the coolant reservoir.

I always refer folks to alldatadiy.com for requests like this.

Jump start does what? Do you have dash lights? horn etc. Trying to figure out if the battery power is getting anywhere. The battery could be dead again from parasitic drain. The cables could be damaged from corrosion. The neutral switch could be defective of loose.

Time for service

Might just be indicating a fault in TCM, have vehicle scanned.

Hello, I had a similar problem with my expedition--where the lights would not go off, allowing me not to arm the vehicle. I had read that in high humidity sensors and or mechanisms tend to stick. To solve my problem I used some silicone spray in every lock mechanism--cycling the locks by opening and closing the doors several times after spraying the locks. I have to do this once or twice a year. Hope this helps--

Oh Your Done With That Piece Of ....

It's alerting you to an upcoming maintenance interval (oil change, etc...)

on my 2015 golf and my old 2011 golf, this meant the tire pressure has issues.

take it in to a diesel specialist shop as the vibration can be from misfiring injectors or low fuel pressure to the injectors if you haven't had the injectors serviced you are over due for injector tip replacement at 80 k/h it could be cv joints problem but that should have come it earlier check wheel bearings condition and adjustment

Under the hood.

It is caused by water vapour in humid warmer air inside the vehicle condensing on the very cold windscreen. As long as the interior glass surface is much colder than the inside air it contacts you will get condensation forming on the inside surface. 2. If you equalise the temperature of the air inside the vehicle with the outside temp for 5 minutes before locking up your car you will minimise condensation, as will garaging it. If you drive around with the heater on full on a freezing cold day, stop the car and lock it up exposed, you are going to get condensation, especially if you have used the recirc control to block the outside air from entering the climate control system in the cabin while driving. 3. If you are having this condensation issue set the air controls on the car (before you turn it off and park it) so that outside air can flow in through the cabin venting system. When you drive around constantly with just interior air circulation and no outside air entering you are going to get a build up of humidity.

sounds like the ignition switch (opposite the lock) has gone bad. I'm not sure if you are looking for the source of the problem or a fix like what parts do you need or just how to shut off the engine ? you can remove the shroud around the steering column find the switch and unplug the wiring harness from the switch. this should kill the engine. If you don't want to dis-assemble the shroud, then you can pop the hood, find the coil pack (I don't know if the VW uses one big coil or several small coils for each cylinder/spark plug). If it uses several small coils, there should be a main controller for all of them. unplug the controller or the one large coil. this will kill the engine. Next you will want to disconnect the battery so it does not drain over night. Because we don't know the condition of the switch, I can not tell you if re-connecting the battery and the coils will allow the car to start again or not. So make sure you kill it some where convenient and not in the way, also easy for a tow truck to get to if you may need one. Hope this helps

1. Check the air conditioner fuse and replace as necessary.
2. Air conditioner system discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary.
3. Air conditioner low pressure switch defective. Replace switch.
4. Air conditioner fan resistor pack defective. Replace resistor pack.
5. Loose connection, broken wiring or defective air conditioner relay in air conditioning electrical circuit. Repair wiring or replace relay as necessary.
