I think I have an answer But bear in mind that this is my assessment with the limited information at my disposal. I'll walk through my reasoning here. If someone finds a flaw in my logic then I'm all ears. Here is a summary of your data +-------------+-------+-------+-------+-------+ | Condition | LTFT1 | LTFT2 | STFT1 | STFT2 | +-------------+-------+-...

Model number differentiates the power (and usually size of the engine) of the car. You can often expect that car with a larger model number will have better optional equipment (it is valid for BMW 7 series models, perhaps series 3 and 5 have the same tendency). Models with bigger engines usually have different (stronger) suspension and stronger brakes. They ...

I believe SE stands for "Special Equipment" on BMW. Basically individual options. The "M" on the steering wheel means it has an M Sport package, mostly prettier design trim - bodykit, M badges, steering wheel, shift knob, exhaust tips, etc. Possibly a harder suspension as well, not sure if all models get that. From the pictures the BMW is an E90. If the car ...

Sounds to me like your starter motor is on the way out, as you are getting enough power, as a bump start is working, and sometimes you are able to start normally. This isn't that uncommon - they do take a lot of stress and load, and the internal friction can end up being too high for them to cope with. A temporary fix I have used in the past is to whack ...

What is a shock absorber? I'm going to answer the basic title question with a carefully selected quote from the great Wikipedia: ... their intended sole purpose is to dampen spring oscillations. Think of how you want your car to ride when driving down a smooth road that has a bump or pothole. You expect to feel a mild jolt when the car travels over ...

This be what the internet gives me. I have never owned a BMW but I hope this helps. In the picture look for the red arrow and on your car look on the left rear side of the engine.

I'm guessing that these are BMW spec runflat tyres? This isn't the first time I've seen such damage. Apparently, because they are intended to be used in an emergency without pressure, the sidewalls are thickened / reinforced. This basically means that they are made from several layers which delaminate with apparent regularity. You may want to get the expert ...

If you are hearing the starter turn (typical starter whir), the most probable problem would be the one way clutch has gone out. It's the part of the starter with the teeth on it which engages the starter ring gear. If the solenoid has gone out, the starter motor will not spin, because the solenoid is the part which forces a large copper washer into the posts ...

They may not have bled your cooling system properly As a possibility, if you had air trapped in your cooling system it would expand as the engine approached operating temperature. It would eventually, hopefully, make it's way into your radiator where the air would get released into the overflow tank by a valve that opens with higher pressures. As the ...

I've got the same sort of function on my Seat Leon (and on my old BMW 320D) - if you drop the clutch quickly enough it will move the car a little. Although I doubt that's enough to get you clear of a railway track. I would err on the side of caution in the event of being stuck on the track/road etc and evacuate the car quickly and safely (i.e. pay ...

I do not understand why the coolant system needs a bleed screw at all Because air pockets. Filling up coolant doesn't necessitate that the entire system will be filled with coolant. There are parts of your cooling system that will trap air when it is refilled. The bleed screw is a means to expel the trapped air from the system. I repeatedly fill the ...

If the picture you have attached is similar to the starter on you car, then the power to the starter motor is only delivered if the solenoid operates, so the solenoid must be working. However, the shift lever labelled in the picture, that pushes the pinion forward to engage with the flywheel may be broken, that would explain your problem. Your problem ...

I agree with @JPhi1618 that it is related to the MAF sensor. From the picture you provided in your comment, it appears your (really good looking) MSR intake comes with its own MAF sensor housing. I too am unfamiliar with this car, but the MAF housing on your new intake is likely a different diameter than the OEM housing. This causes problems, as your OEM ...

It will most certainly be more expensive if you get a professional to repair this bumper for you. However, it will be a safe investment on your trade-in if it is restored professionally. We cannot discuss price on this platform, but, the cost to do this yourself versus taking it to reputable shop will be substantial. If you decide to do this on your own, it ...

A knocking noise when braking (or during less noticeable maneuvers) can be attributed to worn front suspension parts - especially control arm bushings. The image below is from some random heavily worn lower control arm bushings. As you can see, the rubber wears out and the connector in the middle is free to wiggle and knock around. Using your brakes puts ...

I've rebuilt a few transmissions (actually a lot of transmissions LOL) and no, manually shifting is just fine. All your doing is replacing the TCU with your own shifts. So your just fine manually shifting the car. WOW just saw this was a four year old question... sorry folks.

All cars are different, especially when it comes to clutches. Some have, as you say, a high engagement point on the clutch, where you can almost let the clutch out all of the way before it starts to engage. Others do it much lower in the clutch pedal arch (further pushed towards the firewall). It's just something you have to get used to. I cannot tell you ...

Your problem is caused by decompression valve problem in 650 engines prior June 2012. Only way to get rid of it permanently is to replace decompression valve, which fortunately is not a huge job. BMW bulletin about the issue: http://www.gravesurrounds.com/bike/hotstart.pdf Chances of having hot start problems due decompression valve are higher when your ...

The OP responded in the comments and stated the fix. He primed the motor with carb spray to get it going. Perhaps it had a mechanical fuel pump or needed the fuel rail primed in some way. OP's response as the fix in comments below Found out i need to spray some brake cleaner into the intake to prime the engine

The mileage of the car doesn't matter as people can get the mileage reversed. Which make the buyer dumb infront of them. I sugget you Look for the obvious signs like the head-gasket's condition, any oil leaks, try looking at the under-frame,signs of rust,check the relay box.(reason, because the relays are long lasting in most cases,and if they're replaced ...

I believe that what @JPhi1618 stated is a major factor in your rich condition: Could the different air flow path cause issues for the MAF which would have been tuned specifically for the stock intake? And that this statement that you made to counter I believe not to be true: BMW uses the same Bosch `MAF` sensor on all turbo cars. I highly doubt they ...

I know nothing about BMW, but this might help. My VW Jetta had a "La Cucaracha" warning buzzer that was plugged into the fuse box and looked like a relay with a speaker on it. Rather than unplugging it, I covered the speaker part with several layers of electrical tape. The tone could still be heard, but it was very quiet and not nearly as annoying. So, ...

Are you referring to the Driveshaft FlexDisc?

I'm afraid the only way to resolve this is to get matching width wheels plus matching sized tyres across the back axle. Even with the same sized tyres on different width wheels, the effective surface and sidewall profile shown to the road will be different. You may have success trying to find a second hand set of wheels cheaply or even buy an incomplete ...

Sounds like it's possibly involved with the transmission and/or clutch. But first, I would check all the heat shielding on the car to make sure that's not a factor. When the transmission is engaged (when the clutch is not depressed) it can cause some NVH (noise, vibration, harshness) that will cause nearby heat shields to rattle and make it sound like a ...

I would check the idle air control valve, or the IAC. This might likely create the exact symptoms you describe. Determining if it's working properly is a bit of a chore for a DIY person, but this is where I would start. The part looks about like this: And I think was located about here on an '88, behind the Vane Airflow plugged into the checkboard intake ...

Please take the following text with a grain of salt as this is just an interpretation of a complex problem from a random dude on the Internet The steering angle sensor issue (DSC) is the most dangerous (and probably expensive) issue as your road safety depends on it. Perhaps it is caused by the later mentioned electrical issue, but this is something ...

Welcome to Mechanics SE! A white milky, mayonnaise like substance is indicative of oil and water mixing. This could be down to a failed cylinder head gasket or a failed oil cooler. I'm not sure if your car has an oil cooler but the first thing I'd do would be to have the engine either compression or leak down tested. Either of these tests ought to ...

Two possibilities occur to me: a too-large turbo or a too-loose wastegate. when I press the accelerator there is no power until the rpm tachometer reaches 2500 This almost sounds like the replacement turbo is too large. when I press the accelerator there is no power until the rpm tachometer reaches 2500, then I need to release the accelerator ...

Wheel speed sensors would explain the ABS & TCS problems, but shouldn't affect the transmission. Does your transmission fluid smell burnt? Is the level OK? Does the car shift normally at lower speeds? Shifting an automatic manually doesn't hurt anything (unless you downshift at too high a speed or something), but it's hard to say what might happen ...
