I have a 1998 740iL that I plan to retire to our Florida condo. It
will be driven only four or five weeks out of the year when my wife
and/or I are there. What should I do to keep this car happy during the
time it is sitting idle? I suspect one thing is, disconnect the
battery. Any reason NOT to do that? Anyone have experience with
quick-disconnect products? All advice and comments welcome!
I live in Florida year round. You could leave it with me and my 98 740iL
and 97 M3. I'll drive it periodically for you to make sure it stays happy.
I also do most of my own repairs, so if it needs any TLC, I'll take care of
that for you as well.
You would need to put gas stabilizer in it and put the battery on a
trickle charger (a smart one that knows when to stop charging). Even
then you're going to have trouble with the rotors rusting and the other
effects of it being idle. Cars don't like to sit unused.
That is not what those covers are for. They are to limit the UV
exposure of the tires. Tires on RVs tend to dry rot due to the UV
before you can wear them out. Shading them from the sun will extend
their life some. Parking in a garage does the same thing.
I would assume that it would be in storage in a dry garage, in which
case rust on the rotors will not be a problem.
I also would not disconnect the battery, instead just put the car on a
battery tender (special trickle charger for long term storage) that will
periodically recharge it but not constantly so it won't cook it.
Also, the OP will want to increase the tire pressure to the max (as
stated on the sidewalls) for the duration of each storage to help limit
flatspotting. Either that, or jack the car up at all 4 corners and put
it on jackstands.
Just let me keep it here in my garage in Texas. I'd be happy to garage it
for you, keep it cleaned up and make sure it gets driven everyday. When
you need I'll bring it to you and not even charge you for it. :-)
Long periods of non-use can be very bad and ask for trouble. For example we
used to store a Corvette through Michigan winters. As a result, the water
pump failed (and took an ignition module with is) in under 12,000 miles. If
you are going to do this, at least use a storage-type trickle charger. These
things are very small and can only put out a few amps. They're are not meant
to charge a battery, just keep it charged and they work great. Some even
claim to desulfate the plates.
Get a trickle charger from BMW. Don't disconnect the battery. Keep the tires
inflated at all times.
The trickle charger will maintain the battery and not disconnecting it will
keep all the settings intact. Do not just start it up for a while. If you or
someone is going to start it up, make sure you drive it till it gets to full
operating temperature for at least 15 minutes or more.
How long can the tires sit before they start to crack? Would it be better to
put the car on jack stands so the tired are just off the ground and then
lower the pressure about halfway?
Are critters an issue in Florida? would it be a good idea to tape the tail
What about oil? Does this car require synthetic oil? how would the oil hold
up to sitting for that long?
