Noisey Alternator.

I have been told my alternator is noisy. Presumably bearings, I really
do not know. My mechanic cannot do it reasonably as it would mean
having the car off the road for days while the alternator was
repaired. Is this a known problem with 1998 535i's and how much is it
going to cost me to get it fixed please?

Days? Repaired?

It takes an hour to take it off and put a new one on. Assuming I used the
correct engine for your car, the alternator will cost you about $250 if you
go to the parts store yourself and get it. I can't tell what the price will
be if your mechanic buys it and passes it along to you, but $300 sounds
about the right ballpark.

I haven't looked at the specific application, but alternators are usually
pretty straight forward. They have a belt, sometimes two, and two or three
bolts and a connector. Loosen the bolts and remove the belts, unplug and
remove the bolts the rest of the way, install the new part in the reverse
order.

Oops, I looked up the price of an '88 5 Series, not a '98. Sorry. I can't
see that this would change the price range significantly. Go to
www.napaonline.com and plug in your car's data, and see what comes back. I
am not suggesting that Napa will have the best price, but they have a pretty
good look-up engine that will give you a good idea of the price you will
find. Frankly, you can drive down the corner and ask the guys at the
autoparts store in you neighborhood, and they will probably have it in
stock. Write down the part numbers from napaonline (print the page) because
the guy on the corner can use them as a cross reference.

Alternators can also be rebuilt and do very well like that if it's a good
shop, for much less money. But often, more downtime.

That is the position exactly;-)

Got the bearings replaced on my '95 328 5 years / 100k miles ago by auto
electric specialist. Cost <?50 (say $80) no problems since. Dealers wouldn't
bother with a repair - too much hassle and not enough profit I guess.

In the UK, their labour rates would make it cost more than an exchange
unit. Assuming they had someone who could actually do it. ;-(

Yes that is the direction I was going to go but I have now discovered
it isn't the alternator at all but the tension pulley beside it on top
of the belt thanks;-)

That is completely true, but downtime is a concern of the original poster.

Of course.

I suggest it because my dad opened mine because it was noisy, with 335,000km
on it.  He replaced the bearings for about $5 from his industrial supplier,
and the brushes for about $8 at the local alternator store.  Couple hours
later it was back on the car running perfectly.

Again, this is beyond the scope of the OP's expertise. His mechanic has to
take the car home, remove the alternator and take it apart, return back to
town on another day to procure the bearings, then return home and rebuild
the alternator during his off hours. Something that will take just an hour
or two, maybe three, for you and I will take at least three days for the OP.

And, it turns out the idler pulley has smoked its bearing anyway, so the
alternator is OK.

Well if the bearings just need replacing I do not want to buy a new
alternator especially at those prices + 17.5% VAT (Tax).

You can get a rebuilt one for usually $200 or less.  Its easy to do yourself
if you can work a wrench.  If not, it shouldn't take a repair shop longer
than a hour, hour and a half tops to do it.  I had never done one before and
did the one in my 97 M3 in just over an hour.

That is begining to seem like the only option open to me atm. I have a
place in mind and I was just checking out figures really. Thanks.

My mechanic would take the car to his home 30 miles away after he left
work on a Saturday. He would then take the alternator off and bring it
back into town on Monday to be repaired. Pick it up on his way home
and refit it that night and bring the car back on Tuesday so I would
be without the car for a few days. I cannot do the job these days as I
am just too old to get underneath it.

That is why he will take so long to do such an easy job.  Once upon a time I
owned a 1981 Chevrolet pickup.  It took me an hour to replace the
alternator, and that time included getting the rebuilt unit.  You might find
that finding a rebuilt alternator for a BMW not quite so easy.

The rebuilt units for the pickup cost about $40 exchange; a new alternator
cost $200.  That is reason enough to get a rebuilt alternator.

A twist to the saga. My drive belts started screeching today while I
was 40 miles out and I nursed the car back to an auto electrician and
asked him what he could do about the alternator (that I thought had
packed up) and it turned out there is nothing wrong with the
alternator at all. The pully on top of the belt just beside the
alternator was in the process of disintegrating. The car is now off
the road awaiting a new pulley which is much cheaper than an
alternator but I have to wait some time for the item to be ordered by
BMW. I am not a happy bunny at all.

One more time, go to www.napaonline.com and plug in your car's specifics.
You can find out the availability of pretty much anything your car might
ever need. Many of the parts you will need from time to time can be
purchased from the aftermarket and they will work as good as the original.
Yes, there are parts that you will want to get only from BMW, and some parts
that you must get from BMW. Of these two, I only get the ones that are only
available from BMW. This includes stuff like the fender liners and shift
knobs, and parts that are specific to my BMW. Parts that are common among
all cars - serpentine belt tensioners, water pumps, etc. - are available in
the aftermarket, often at a fraction of the price.

Thanks Jeff but I am closer to Germany than I am to your link. I am in
the UK but thanks;-)

I understand Pete, but there are auto parts stores in Europe. You can still
find the parts you need in the aftermarket. And Napa sells Bosch, Beck
Arnely, and other European parts maker's products. So, if you find your part
at napaonline, you will have enough information to cross reference the parts
locally. And, if you know that the Framis Valve you need costs $25.00, then
you will know that the mechanic is taking advantage of you when he lists it
on the repair bill at $150.00. (You can make the conversion to euros ...)
Knowledge is power.

Yes thanks Jeff, that is a good point.
