#12 of 21 BMW DSC light acting up after tire rotation
Apr 18, 2011 (7:56 pm)
re: 2000 BMW 323i\130,000 miles
Since I had my tires rotated and balanced about 6 weeks ago, my DSC has been acting up. First, it was coming on once a day. When it kicked on I would hear a noise (click?) in the engine, car would kind of pull, but then drove fine but light stayed on until I turned car off then on again. Then after a suggestion, I checked my tire pressure & they (Tires Plus) overinflated my tires to 40. I deflated them down to about 30 where they should be about at, then the DSC was coming on about once week, or at about 100 miles. Then for the last 3 days it is coming on again more frequently. Half of the time the light just comes on w/ no noise/slight pull (ie indication it is coming on).
As a side note, I had some engine work (spark plugs, coils, tune-up) done on the car about 1 mo ago and they did full diagnostics and module did not show any error codes.
Any suggestions as I'm not looking to put much more into the car as will be getting rid of same w/in the year.
#13 of 21 Oil change question
May 06, 2011 (5:58 pm)
I may buy a Preowned BMW 3281 manual transmission from a private buyer. What concerns me is that going by the car fax reports the first oil change was done at 11k and the next at 15K. Is this normal? Will appreciate any advice

Oil service is included in the BMW maintenance plan... It's an experienced based system, that usually calls for an oil change around 15K miles (though, it's variable..).
Though it's not officially in the program, BMW has allowed low-mileage drivers to have their oil changed at the 1 year mark, even if they haven't reached the oil change interval... Rather than re-setting the system, they just get an additional oil change, and then have it changed again when the indicator calls for it...
That scenario fits perfectly with what you report.. At one year of service and 11K miles, the car's oil was changed.... then again, at the regular service interval of 15K..
It's all good!

OVERHEATING I have a 1993 bmw 318i 4 cylinder,
E30 engine series 1.8L, 4-spd automatic trans, DOCD car that keeps overheating. I have a brand new radiator (install by a certified mechanic shop, but couldn't afford to have them work on it after that), I also needed, so I bought and install, a brand new fan clutch. Now here's my question, I have bought 2 thermostats, one from O'Reilly's Auto Parts and one from a specialized European Automotive shop. Both places gave me a thermostat that opens up at 192 F, with the specialized shop insisting they were giving me the right thermostat, an OEM part. I told them that my car requires one opens up at 176 F, but they still insisted that I was getting the correct one. Could installing that thermostat cause my car to still overheat, fairly quickly? Also we checked the waterpump and and it appears to be good, but were not sure. Oh, also the hose going from the tank is cool, but the return hose going back to the radiator was steaming hot after I test drove it and the temperture read hot in the red zone. Thank you, Shelly B.

Well if the thermostat were stuck, or in backwards, yeah, it could overheat the car quickly, but being the wrong temperature rating--no, that wouldn't matter.
Given the age of the car, and being a 318, you'd best check for a bad head gasket, too.

An M42 shouldn't need a cylinder head gasket prior to 200K miles unless it has been severely overheated(or the profile gasket has never been replaced). It sounds as if the cooling system wasn't bled properly.

One might hope, but there's no such thing as 'shouldn't" to the thorough investigator because all cars are treated differently in their long life. You gotta look at everything as possible or you might get tripped up on diagnosis. I brought up the head gasket because he said it overheats "fairly quickly", and a bad head gasket or cracked cylinder head is very good at boiling water for tea.
But sure, let's hope that's not it. Seems like an air block would cause his temp gauge to move around alot.
A simple pressure test should solve this problem. Pressurize the system, then while holding the pressure, remove the spark plugs one at a time. If you see coolant on the tip of any of them, there you go.

A head gasket problem is certainly possible, but as I said extremely rare if the car has never been overheated. If the OP has continually overheated the car the whole engine may now be toast. That said, I can guarantee that an incorrectly bled cooling system can generate all kinds of bizarre symptoms.

Well it IS a 20-year-old car, so head gaskets simply wear out like anything else. It's certainly not a "fault" of the car, any more than wrinkles on a person.
And if we add in the inherent weakness of the cooling systems of most 3-series in the 1990s, one has to at least be suspicious of overheating stresses, as you pointed out.
