BMW Z3 E36 Z4 Do I Have a Problem Oil Level Sensor

07 3.0Si with 15000 miles on the clock with the electronic oil level sensor no apparent oil consumption problems. Had a dealer oil change for annual low mileage service about 3 months and 2000 miles ago. As a habit I always check oil level each time I use the car. I realize that with someone else performing the oil change the actual oil level (a little overexacta little under) is unknown due to the

The following is right out of the owners manual. There is no way to check increments less than 1 quart. It either tells you OK or that it has too much oil or not enough by 1 quart or more. It will never tell you that it is a fraction of a quart low. RTFM Reference Mobility Driving tips Controls At a glance 93 Add engine oil at the earliest opportunity e.g. when you stop to refuel.

BMW Z3 E36 why did my Z4 just take this much oil in

Hey everyone I made a major stupid today. I washeddetailed my car and decided to change my oil as well. I drained the old oil replaced the O-Ring replaced the filter replaced the gasket for the oil plug and sealed it back shut. I SHOULD HAVE PAYED MORE ATTENTION TO WHAT I DID NEXT. I filled the first 5 quarts of fresh oil and then STUPIDLY put in the next 5 before realized Oh my god that was incredibly

if you overfilled the crankcase with oil but you did not crank the car then there is really nothing to get damaged providing you drained the oil before you started the car. If you did try to crank the car then you could and will likely have blow-by through the exhaust system. (this will be evident fromt eh exhaust pipe) or crank bearing damage from the high pressure of the pistons splashing into the

BMW Z3 E36 Z4 Coupe.. went in for 1yr oil and came out with problems

Hi I took my 2006 Z4 Coupe in to the San Diego bmw earlier this week for an oil change and to check on a weird high pitch whine that occurs when the car is up to temp. The dealer replaced the fuel pump which apparently was making noise. When I picked up the car the porter drove the front end of the car into the high curb. They had to sand and repaint the front air dam. Next day I went to pick it up

I took the car out for a drive today and it didnt start to rattle until 15 minutes or so on the freeway. It may be the the heat shield as Ron mentioned since it is making the noise when the exhaust system has suitably heated it up causing the shield to lossen and rattle. Kind of sucks because the delaer wont hear it unless they drive it enough to get it to the point of rattling. After that it doesnt stop rattling until the car is turned off for a while.

BMW Z3 E36 Dealer Service mileage question - Z4

2007 Z4 3.0i - Bought as a CPO with about 26K miles. Im getting close to the end of the free dealer service 4 year window and want to make sure I get what I can. Our mileage (about 31) is very close to 15K since the last full service (not including the CPO service and the CPO dealer did not reset the service mileage counter). However the mileage counter show about 2500 miles to go and Ill never get

wasnt sure if the service counter was just a linear mileage counter or measuring some other way. Ill have to do the math but my avg mpg indicates 24.2 or so. How did you find or know the 2500 litres formula That not a bad setup since it would somewhat increase the interval for mostly highway miles and shorten for lower city mpg. The 2500 litres between service was published in about 2000 in some bmw

BMW Z3 E36 Z4 - Steering issues

I just got rid of my beloved Z3 and moved to a Z4 3.0 perf & sport pkg. It is a totally different ride and I love it but on occasion the steering seems grab and release control .. kind of spotty. It allows the car to jump around at higher speeds to the point that it seems almost dangerous to me. Im new to the forum and didnt go back through too many postings - but does this seem like a problem others have had

steering anomalies I feel are related to run flats or the electric power steering. All I know is that I have to constantly correct the steering on the roadster compared to driving the same roads in the Z4M. My friends who have roadsters have almost all removed their run flats in exchange for regular tires . They like the handling changes and have never looked back. BTW the last time I checked bmw

BMW Z3 E36 Z4 Possibly bringing a car from California to Seattle - water pump thoughts

Ive been looking at Z4s. While I am not ready to buy (that will come in the late springearly summer) Im actively reviewing the selection of cars out there and have been doing research on them. Ive come to the conclusion that the Seattle & Portland areas have a pretty unfavorable selection of used Z4s. Maybe its due to the climate (3 to 4 nice months in the summer rainclouds the rest of the year). So

Posted by Shrike That having been said how risky would it be to bring a Z4 with 40-60k total miles on the 800 mile jaunt (approximately) up I-5 in the late springearly summer from NorCal to Seattle Could the cooling system be a major area of risk and should I nix a car unless it has been documented that the water pump etc has been replaced Once I get a car I plan on taking it to a local bmw

BMW Z3 E36 Help me Decide Sold 911 buying either Z3 3.0 or early Z4 3.0 (Beemer newbie)

Folks - At age 49 I recently purchased my dream car a Porsche 911. Mine was a 2002 Porsche 996 Carrera Coupe 6 speed low miles and in superb condition.

I also did not particularly care for the long throw shift heavy clutch combo when noodling around town. (At speed these cars

The newer ones dont even have an oil dip stick. Besides I totally agree with Mpire on the styling question. Also bmw

BMW Z3 E36 96 Z3 - How do you reset the reminder light after an oil change

To save money I had my cars oil change done in a good shop that is not a dealership. How do the reminder lights get re-set Mine still shows one yellow and the words inspection. Im sure folks out there who do their own oil changes know how to reset this. Thanks

I just did an oil change and the recommended way worked on my Z4 produced in 052003. I did an oil change for a guy with a Z4 made in 112002 and for some reason i had a tough time with it and gave up. I dont know if it was something i did or if it doesnt work on ones with that inspection system(The way it displayed the miles and inspection was different than mine)....But yeah basically car off position....hold

BMW Z3 E36 Lack of oil dip stick

I just heard that the 3.0 si does not have an oil dip stick. How long has this been the case with the 3.0 For those that have this engine doesnt this drive you nuts I would not trust an oil sensor to tell me what my oil level is. What was bmw thinking Was trying to justify an M over the si and this alone would push me over the edge.

BMW Z3 E36 Z4 75000 miles

OK old schoolers what would you do (or have done) to your Z4s at the 75000 mile mark I bought the car last July with just over 72000 miles on it and a recent independent dealer service. I just went over 75000 and have not done anything to her except the inordinate amount of washing and waxing.

and possibly all 4 rotors. Other than that do you normal oiloil Filter changes plus the cabin filter spark plugs and battery if its over 3 or 4 years old. I would bleed the lines since the fluid is old and check the belts also. If you have to take the rotor and caliper off to do rotors and pads you might as well pack some grease in the wheel bearings as well. My mechanic who has been working on bmws

The hardest part on both the Transmission and the Differential is the fluid break in period. Just keep that in mind for the future. Power Steering is a very small concern. Its nearly all electronics on this car. After years of racing cars i have found that cars dont break any more often when you baby a car or if you dog it after a fluid change. Of course it doesnt hurt to heed the advise of bmw.

BMW Z3 E36 Z4 Tire warning

I was driving on the freeway around a long sweeping corner the other day at 80MPH in a recommended 50MPH zone (yellow suggestion sign) and my (A) tire warning light came on. Im assuming the computer thought that the tire was aspherical and had a puncture. Is this normal or am I just pushing the car too hard in the corners Im used to motorcycling and I didnt really think there was that many Gs going

when one tire was slower than the others it deduced that the tire was low on pressure. The SUV has pressure monitors on each tire that transmit pressure to the cars computer. I believe the new Z4s are like this. So if the light comes on and then after a bit goes out then I wouldnt worry. But check the pressures anyway. As Jeff said never depend on the dealers service department Especially the bmw

BMW Z3 E36 328i to a z4 si coupe

My lease is up on my 328i 6mt zsp in a couple of months and Im considering a 0708 si coupe as a replacement. I love the looks of the z4 coupe but have never driven one...can I expect a big difference in driving dynamics compared to my e92

The other major maintenance differences with the M is the more expensive oil used (10-12 per qt vs. 6ish per qt for standard bmws) and brake parts (1000-1200 in parts for the M vs. 5-600 for the standard Zs labor cost should be similar.)

BMW Z4 E85 E86 E85 vs. Gas 87 octane

Hey guysgals Ive been wondering this for a while about the differences in actual cost per mile between E85 & Gasoline. Well I finally got around to doing a test and this is what I found for my 2007 F150 5.4 3v. E85 - total miles to a tank 350 - used 27.5 gallons - 12.7mpg - e85 price 2.26 - tank cost 62.15 - cost per mile .18 Gas 87 Octane - total miles to a tank 400 - used 27.5 gallons - 14.5mpg -

Ok.. here are some basics that are missed. E-85 as was said is subsidized by the government. That means all of us are paying for it in taxes. Taxes bad. Brazil is almost all ethonol. It is totally subsidized by... TAXES.... once again.. taxes bad. The food price increase because of ethonol is unacceptable. It puts an unfair burden on the poor... which leads to more welfare. Welfare bad. Also when

You CAN run your truck on E-85 as long as you have some extra to throw at it. Now understand most of this was talk to install it on a Turbo charged system due to the high octane rating of the fuel[105]. To get it running in your truck you will need the following

BMW Z4 E85 E86 Whatever happened to e85

I have read quite a bit about e85 and it seems the only thing really that needs to change is it can cause a lean condition. Flextek says they have a contraption that fixes it. I am not gonna try it but its Friday afternoon and Im bored at work so I thought I would see what others think.

E85 is mildly corrosive. Quite a lot of materials that are perfectly happy immersed in gasolene or E10 gasohol erode rapidly E85. It is also electrically conductive so electrical components in the fuel system have to be insulated.

E85 is going to destroy your fuel pumps and fuel system and fuel injectors. E85 is not equal to or about 105 octane and the octane is really more along the lines of 98. your entire fuel system will be destroyed in less then a year using E85.

BMW Z4 E85 E86 E85 or just regular GAS

My 2011 F150 is my first flex-fuel vehicle and I have mixed feelings on whether or not to use E85 in it. Mostly it comes down to the effects it may have on the engine life. I also know that gas mileage is not as good and there are other environmental reasons that E85 is not all that some crack it up to be... Who here has opinions on this Gas prices are making E85 look like an option that is worth considering but is E85 just not a good option

I change my oil every 5K no matter what. I like the performance of the e85. It picks up a little timing which gives you a little more pep. I dont loose anywhere near 6mpg. More like 2.5 for me. If it is 45cents lower that about costs out based on how it performs. Higher alcohol content should make it repel or get rid of moisture in the fuel system better. that is basically what HEAT is. These engines

BMW Z4 E85 E86 Switched from E85 back to gasoline

Been running E85 in my 02 5.4L for quite a while. Decided to switch back to gasoline. The 25 gal tank had 8 gals left in it so I was gonna switch tunes back to gas and fill up. I switched to the gas tune and ran the truck on the remaining E85 to the gas station. I filled up with premium and drove back home. It ran good and since I still had 27.2% alcohol I kept an eye on the fuel trims. Runs a little rich but not bad.
