Hi, I have an '05 Jetta (BEW) that makes an intermittent growling noise on start-up that causes the battery light on the dash to light while the noise is heard. After about five minutes of idling it stops making noise. The battery light comes on only when it makes the noise.
I did the searching on this forum and it sounds like the clutch pulley is the problem but I don't recall anybody saying their battery light comes on with the noise. Why would a noisy pulley cause the battery light to turn on?
I have some numbers off the alternator but don't know if it's a Bosch or Valeo, and the dealer couldn't tell me either as of now.
I checked the pully and it spins in one direction only although it felt just very slightly a little rough, I expected from the noise it would be worse.
Anyway, here are the numbers on the alternator:
038 903 023L
90A 14V
3RO 32/04
0 124 325 001 (904)
Made in Mexico
Also the alternator spins very smooth both ways with no noise.
Can anybody tell me alternator I have and if all the clutch/pulleys are the same?
Thank you.
