SOURCE: removing a 2005 2.0 jetta volkswagen battery

Battery is on the drivers side behind the left headlight.  Remove the battery cover by pressing 2 tabs in on both sides, remove fuse panel block by pressing same tabs and fold back, remove battery hold down using 13 mm socket and ratchet.  Be careful not to loose bolt and hold down.  Next disconnect battery cables.  Hold those out of the way.  pull battery forward and up.  Install in reverse order.  Note removing battery can cause codes in the control modules.  Radio could will more than likely have to be entered and window adaptations will have to be reset.  This really should be done by a dealer or someone w/ Vagcom.  The reason is sometimes you need to reset the throttle body and transmission adaptations.

If the door panel has never been removed then it could possibly be a bad speaker.

Being a 99 model it could also have a plastic liner under neath the door panel that has dry rotted and needs to be removed.

I'd place my wager on the speaker though.

If the panel has been removed check to make sure that you don't have any broken clips that attatch your door panel to the door.

SOURCE: my epc light went on in my 2002 volkswagen jetta

Take it to the dealer, the EPC warning light - and even more the failsafe run which doesn't allow you drive faster than 20mph) is an indication of serious motor troubles. They can read the ECU faultcodes, which should be a good startingpoint for troubleshooting the cause ...

You could do some basic troubleshooting like checking the air filter, the oil level, the spark plugs, etc. You didn't fill it up with bad gas, did you ? And does the engine make strange noises/vibration when running idle ? In case you fixed some obvious cause, you can dis- and reconnect the battery to erase the engine's faultcode. If it's not fixed, the EPC (and failsafe run) will simply come on again.

My advice would be not to drive it untill it's fixed to prevent more potential damage.

Check your battery charging rate. A possible alternator or battery failure.
If the battery is charging at around 14volts, then replace the battery.
If its charging anywhere below 13.5, then replace the alternator.

Hi,Kathmandu, Anything is possible when we want.To make your Jetta conventional with carburetor you need some parts extra such as inlet manifold and a carburetor-make sure is PIERBURG-2.Ignore fuel pump by removing the fuse,and then repair all fuel pipes from and to fuel tank.Don.t touch the electronics

Usually a dealer item, or junkyard. I've seen some on e-Bay. Also check europartsdirect.com. Do not replace them with hoses and clamps, due to a chance of a leak and fire. The fuel pressure is rather high.

OXS Dash light


There is a counter installed in the speedo cable. Open the hood and look below the coolant resevoir, there should be a black box that the speedo cable goes through. Press the reset button on the box and the light should go off.
