[Biturbos4] LOW VOLTAGE CONDITION ?

[Chris Newbold]

Alternator and/or voltage regulator. The regulator is integral to the alternator and likely not replaceable independently--at least not cost effectively. I would get this fix ASAP-- I had exactly the same symptoms and the car lasted about two days before the battery was shot and I was dead on the roadside. You may find the busted alternator has fried the battery--that's what happened to me.

A good wrench may be able to replace the alternator with only the belly pan off; mind did.

> Got a 2001 b5 s4 with odd reading on volt guage. On start it reads 13-14 v like it should but drops to 12.5-12.30 after about 5 min. Batterey is new, belt not slipping. Can drop to 11.85 with max load. New alternator? Volt reg? Can the volt reg be replaced w/o dropping entire nose? Look forward to hearing thoughts
