Well they can easily test for a bad head gasket or a clogged PCV. There doesn't have to be any guess work here. Not sure, but I think your car is too old for extended warranties. I haven't had much experience with them, other than that these are not warranties of course, they are insurance policies, with lots of exclusions possible. They are betting your car doesn't break and you are betting it does. They decide the size of the bet, and you know they've done their homework.

Just about every aftermarket warranty has a giant list of exclusions and the almighty "warranty doesn't cover parts that fail due to overheating". Good luck trying to prove your transmission or motor wasn't overheating when it failed.
Even if by chance you can prove it they have ways to wait you out and more lawyers than you

I have a 07 750LI - the mfrs warranty expires in November 2010; any suggestions on companies that offer extended warranty up to 100k miles current mileage is 29k

Oct 26, 2010 (8:10 am)

My 2009 750 has 13,800 miles. To date, I've added 5 quarts of oil. At my last service, the dealer said BMW spec is that the car could use up to a quart every 1,500 miles. I've never added oil to a car between service.
 
I've also noticed that my car sometimes has difficulty starting. It either takes a while or just times out and stops. Is anyone else having these issues?

Well if this were a Hyundai I might say "let's see how it goes" but on a car of this price category, I find it unacceptable. Have the dealer check for a defective oil separator (fancy German PCV valve). Also play a little game of role reversal on him. Tell him that you are the dealer, and that he has just bought a $70000 car that uses 5 quarts of oil in 13,000 miles. Then tell him it's perfectly okay and ask him how he feels about that answer.

Great idea; unfortunately, it's $95,000.

Even MORE irritating. Hopefully, the oil separator is the culprit here.

You definitely want to have the codes checked. The rough running symptom could be anything from bad gas to a fouled plug (possible leaking valve cover gaskets -they leak into the plug wells This occurs between 60k and 100k, depending on how hot the car runs and climate), or as simple as a MAF sensor going bad. Before doing any major work, have a good independent shop clean the MAF sensor wire..takes about 10 minutes. If the symptoms (and check engine light )go away and then return, replace this (150.00 from autopartswarehouse.com for genuine Bosch part that the dealer wants 375.00 for) . A bad MAF sensor can throw out erroneous codes that indicate overly lean mixture from leaking intake manifold gaskets. As far as the Power steering, it is controlled through the "servotronic" unit, that regulates the amount of assist pressure relative to speed (faster, less assist and slower, more assist). The speed sensor is related to the ABS control module (General Module). When this isnt working it will throw a code from to the OBD unit. A good possibilty is that if you had an ignition hiccup as noted above, the General Module could have cut off power to the Sevrotronic Solenoid. When this part goes bad. gets clogged with filings etc, it will fail to engage fully at lower speeds or at all. Most 740's will experience this at above 100k miles. REPLACE THIS FIRST BEFORE DOING ANY STEERING BOX OR PUMP REPAIRS; its 125.00 from autopartswarehouse.com and about 1 hr to install.
