Bit the bullet and changed everything. No noticeable wear after 70,000 klm since last change but has been over 7 years. Serpentine tensioner wasn't done before and had miniscule movement at pulley. Car will be over 20 years old before due again! Could not budge the alternator pulley, snapped 2 special...

Hi all,

I am seeking advice on a definitive date T5s require coding/registration to account for a new replacement battery? Is this required for a 2008 model?

I am sort of mystified by all of this, and isn't battery charging from the alternator adjusted according to battery...

Driving late today and aircon suddenly went off, then looked at the instrument cluster - red battery symbol - so strongly suspected the original alternator had gone (likely carbon brushes have given up by now - 158,000km0; VW 2009 Passat CC 2.0 TDI (CBBB engine). Anyway, RACV confirmed it was the alternator...

The seller I bought my T5 from told me the alternator regulator needed replacing.

My van has 360,000kms on it. Am I better off replacing the whole alternator while I’m at it?

Can anyone recommend where to buy this from ideally within Australia?

Has anyone else had there alternator go at 100k . Auto electrician said it’s very rare and cost so far for replacement is $2500 nzd to replace

Hi all my 2005 T5 petrol 2.o litre van is nowadays just staying home more often , the battery goes flat after a prolonged period of time and I,v had to jump start it a few times .

Hi all, just wondering if anyone knows what the 2013 Highline alternator voltage should be sitting at ? At starting and whilst running, or is the alternator supposedly a fixed voltage, I’m having varied reading with the scangauge.
Any ideas would be great.

Hi all. thought I'd share a recent experience in case anyone else faces a similar issue. Not long ago, whilst driving along the great ocean road, I started getting weird electrical issues, firstly the radio volume disappeared, then random error messages, and eventually the car dropped into neutral and...

Hey guys,

Been a whilse since i have driven my tiguan, had RACV come by to jump start it and they noted that the alternator is catus as it is charging the battery at 12.7V and at load 13.1V... is this normal for a car that has driven 100k km~? Also how much should the damage be for...

Hi All (first post )

I've had a number of VWs. Currently own a B5 Passat 2003, 2014 GTI Perf7 and a T4 van.

So, I think I fried the alternator on the Passat due to reverse polarity on a jump start (don't ask).

I have VAG COM and it's not showing any codes, however...

Hey everyone!

My mk5 Golf had a flat battery the other day. I have a android head unit which connects to canbus and shows battery voltage. When my car is idling/driving the voltage seems to spend alot of time around 13.2-13.5. Sometimes I notice it around 14-14.5 but not as often as I...

So I started having the ars and abs lights flashing on my mk4 golf, also noticed that this would only happen when I would use something that draws more power like the windows, indicating or turning on the headlights. I comepeltely charged the battery overnight and when I woke up i removed the charger...

Hi all,

I've recently purchased at GTI MK4 2001 and now having a little trouble with it.

It's a very weird issue: If the car stalls, I go to switch the car back on but it doesn't turn over (sometimes). Other times it just hasn't turned over and I've had to push start the car....

Hey all,

So we purchased a (used) 2012 2.0TSI DSG Tiguan with 84,000km a week ago and everything was looking pretty good.

Yesterday out of nowhere the we were driving it near home down a hill and the engine light came on, car lost power and we coasted into a side street. Upon...

hi guys

Hoping someone can offer some advice or suggestions.

I'm having minor electrical problems and on occasion the vehicle won't start without the battery being jumped, but I don't think the battery is the problem, it's still under warranty and is only 18mths - 2yrs old....
