2006 Z4 2000cc. 21000 miles, eight appearances of the light, none explained satisfactorily by BMW. One occasion--caught out the BMW dealer telling fibs. had an apology from BMW. Came on a few months ago. Ignored it and it went out. It's on again now. The car is rarely used-I'm told that this is significant. The light always seems to come on after the car has been running for about two hours. I have no faith in BMW in resolving this, certainly not at their prices.

My wife's Honda CR-V has the "Check Engine" light come on every 7,500 miles telling you to get the oil changed. (It has no way of telling if it's been done or not.)

There are instructions in the Owner's Manual on how to reset it yourself...

That is the temp light for low coolant or over heating.

More then likely you need to change the spark plugs because they are fouling out. Thats the cheapest fix that I would do first! Then check coils.

you cannot check the oil a light will tell you as and when it needs oil which is a dealer only type job ,so its a expensive business .sorry to bring you the good news

Changing the sensors &/or tone ring may work temporarily but it won't last. I have a 2005 and have had it done and it kept happening. Had it serviced at dealer, asked dealer how to fix it or make light go out and on and on....after I think 5 yrs. it is still on. It hasn't affected my vehicle as far as I can tell. Comes on blinks 8 times, goes off....drive another 8/10ths of a mile and it comes back on, flashes eight times...and so it goes tidily bomMust be an Escape kinda thing.

if you tell a BMW garage you only want an age/mileage service, thats what you get BUT they will give you a list(on paper)of things that you may want to consider doing,BMW dealers have strict instructions from the factory and if they dont follow these they loose the franchise...THEY DONT PLAY GAMES like some domestic makes.....(dealers)

There is a lot wrong with "low oil" and low oil is not normal in a low mileage healthy engine.

The dealer is fobbing you off in the hope you will go away.

If the oil is being changed at least every 5000 miles or so there should be minimum oil depletion between changes with only very minor top up needed. Some oil consumption is normal but it should be minimal.

If the oil level is dropping to a very low level in about 4000 - 5000 miles of normal motoring you have a significant problem. The oil is either leaking out or the engine is burning excessive oil or a combination. If there is no leak through faulty seals or by other means such as oil escaping into the cooling passages of the engine, then there is excessive burning.

These engines are known for excessive oil consumption because the problem is a common one in the 06, 05, 04 and previous year builds back to about 98/99. The dealers know all about this problem - as does BMW - and they will try to fob you off until the car is out of warranty because the fix is expensive.

From what you say the problem has not been fixed on your car. Document the oil loss and insist on your warranty rights because your engine is using excessive oil and this is NOT normal in a properly functioning motor with as few miles as yours has. Make it clear to the dealer that you are well aware that excessive oil consumption is a common problem in many of the 325 petrol engines and you want it fixed under warranty.

Then sell the car as these vehicles will cost you quite a bit in repairs once out of warranty and once you clock up around 60000 miles or more. If you have an auto you can expect major problems at about 65000 miles (later if you are lucky) and replacement of the transmission will be necessary. Once you notice any significant problem with the auto transmission it is on it's way out.

leased? take that thing back and dispute that it is not safe to drive. they need to do a complete check up on that vehicle. it could be as little as the the dash malfunctuning, to brake broken and 4wd broken. which idk how that would even be possible. at 21000 miles it may still be under warrenty and there is prob something writen into the lease about problems like this. please go to your dealer

Probably the pollen filters as well, brake fluid and anti freeze. If this is your last free service with the dealer it pays to ask them if you can check the service schedule list for your car.

This might actually be a software issue in the car. It can be taken care of at the dealer with re-programming. Its best to leave it for a few days because drivability concerns such as these can be the hardest to pin point. Best of luck and please let me know if anything changes.
