I have a 1999 VW Jetta GLS 4 cylinder 2.0liter SOHC New Body Style. My Alternator died, according to the technician at the VW Dealer. The electrical system diagnostics done by the tech indicated that the alternator was producing only 10amps and should be producing something like 14 amps. Backing up a bit; during the morning of the failure, my battery light went on. Later that night, I noticed that all interior lighting (including instrument dash-board lights) went dim. Additionally, the brake, ABS, airbag, etc. lights went off and a beeping noise occured. Long story short, my car started to sputter and eventually died on the highway. When I tried to start the car, the engine would barely turn over and the instrumentation lights flickered rapidly. I called around and found that PEPBoys or Advanced Auto Parts had Bosch alternators that fit my car for like $250. Bosch alternators at VW Dealer Parts Department costs $500 minimum. I'm not sure if it's the same one, but the VW guy on the phone said "Bosch". You do your own reasearch. Labor is 1.5 hours. Total from VW Dealer was around $750.00. I'd like to hear the experience of others as well.
You should be able to remove the alternator bracket, on your 1995 Jetta, by removing the three retaining bolts. The bracket should easily come off.
Begin by removing the belt from your 1994 VW Jetta alternator. Remove the alternator wiring harness. Remove the alternator retaining bolts.
Remove the wiring harness from the back of your 1993 VW Jetta alternator. Remove the three alternator retaining bolts. Remove the alternator belt. Reverse the process to install your new alternator.
You will need to remove the belt from your 2002 VW Jetta alternator. Remove the wiring harness from the back of the alternator. Remove the alternator retaining bolts. Reverse the process to install the new alternator.
have you checked the alternator??? that's the first thing that comes to my mind if your battery is being drained
There is no fuse for the alternator.
you might need a new alternator. thas what happend to mine. Did any dash board lights come on and the radio start changing by itself?
Begin by loosen the tensioner bolt. Slide the alternator to the left and remove the belt. Remove the wiring harness from the back of the alternator. Remove the alternator retaining bolts.
changing the bulb
most likely the alternator is bad.
you need to reprogram your radio when the battery has been disconnected - see owners manual
A rebuilt alternator is around $90-250 USD according to the year of the unit and whether you have A/C or not. Figure 1 hour to r&r the unit and test at $75 /hr.
