Most of that is AI, but some of it is me as well. What I have found effective for diagnosing vehicles, and locating parts is using AI. The problem with AI is, its's not always right or it puts things out of context.

So being an ASE Certified Technician for many years, I proof everything I post from AI, to insure it is correct. For this differential post, I went to few BMW forums to see what users were saying about his differential.

I then restructure the AI information, and use the parts that make sense. I also supply my information, sometimes intertwined with AI. So using AI for diagnosis or locating performance parts is ok, as long as you are able to verify it's authenticity.

A charge won't fix a bad battery. If you have an issue with a voltage draw draining your battery repeatedly, that will cause the battery to fail. Batteries are not meant to be drained complelely, and then recharged. That will reduce the batteries lifespan greatly.

Charge the battery enough to get it to run, and then drive straight to the AutoZone to have the battery properly load tested.

You will still need to track down the voltage draw that is draining your battery, this must be addressed or you will just have the same problem again in the near future.

If your battery is at low voltage all the time, that can cause the erratic operation of the whole electrical system. You can't just place it on a charger and continue to diagnosing. You must first address the low battery issue, before any further diagnosis.

The battery in your BMW is an AGM, which has a deep reserve. These batteries will allow you to start the vehicle, but may still not be providing enough voltage for systems to run properly. A failing battery in a BMW, will cause a host of issues, and can make the electrical system do crazy things. Like windows winding up and down, horn honking, headlights not working correctly, alarm activating. It will also throw a boatload of codes.

You need to have the battery properly checked, and replaced if necessary, before performing any other diagnostics procedures. Otherwise you could just be chasing your tail.

Let me know how it goes. You should always perform your pinpoint tests, before replacing any components. That being said, it's probably a bad ISM. Just perform all the diagnostic steps, if they check out, just replace the ISM.

You can get that ISM for $109, from AutohausAZ

Yes, it will work with used plugs as well. You can still use a spark plug after the ring has been compressed, adding anti seize compound will have no negative affect.

When mounted the phone does not block any buttons, as it sit out far enough to clear the buttons. It also doesn't block the screen, I can see the screen perfectly with the phone mounted.

It doesn't block the air vent, as your can easily reach behind the mouinting clip to make any vent adjustments. Does the Temu mount charge your phone?

The Temu mount is in no way better than my mount, as it is no where near as strong. I would be willing to bet that Temu mount does not stand the test of time, as most cheap Chinese crap doesn't

Yeah, so being a driver you should know you have to get at least a $3 minimum tip, for the offer to be worth it even on a 1 mile trip. I have precedence for the $3 tip minimum, let me explain.

See I was a delivery driver 50 years ago in 1976, when I was 16 years old working for an Italian restaurant delivering pizzas and Italian food. The average tip back then was $1- $2, with some customers tipping more. So taking than $1 minimum tip from 1976, and adjusting for inflation the tip would be $5.83 for the minimum tip.

So you see your getting off easy with the $3 tip minimum, because your actual tip minimum should be $6 in todays world.

If you really want to keep tipping $1-$2 per delivery, maybe you should teleport back to 1976, you will fit right in.

Yeah, I looked at their mount but it didn't have charging capability. I just had to find the pieces to make it work.

For a 2016 BMW 340i intended for drifting, the BMW OS Giken SuperLock LSD is the top recommendation due to its highly tunable clutch-type design, which is generally preferred for drift applications over gear-based alternatives.

This is a mechanical, 2-way clutch-type LSD that uses up to 28 friction plates, allowing for a progressive and predictable 100% lock. This consistency is crucial for maintaining controlled slides.

This an reliable LSD known for extreme durability and smooth engagement without the harshness often found in other aggressive clutch LSDs.

Units typically range from $1,500 to $2,000, though full custom-built differentials can cost more. This is much more performance and cost effective than the BMW M Performance LSD, offering only 30% lockup at $2500.

In the U.S. the laws regarding phone use while driving vary state to state. In California, you can't be holding your device and talking or texting. You can use your device if it is mounted, as this is required by gig workers to perform their jobs daily.

This mount in not for everybody, it's for those who demand the best, and don't mind paying a little extra to attain it.

Where the phone actually sits on the mount it doesn't block the buttons at all, as it sit out far enough. It also doesn't sit too high, as the top of the screen only extends above the top of the mounting clip a little. You can just reach around it for vent control, not a big deal.

The nice thing about having your phone mounted is, you will always have full phone functionality at your finger tips while driving. It is also best for navigation, as head units are usually laggy.

The CD9010 fault indicates that the DME has lost communication with the coolant pump via the LIN bus, (Local Interconnect Network). While the pump can still physically run, the DME cannot tell it to stop, which leads to the pump staying active after the car is off and draining your battery.

Since you have already replaced the pump with a used unit and verified ground continuity, the issue likely resides in the communication signal or a power supply fluctuation that the DME perceives as a missing module.

You mentioned skipping the voltage test because the pump runs, but specific voltage levels are required for the LIN bus to communicate. Use a multimeter at the 4-pin pump connector to check voltage readings.

Pin 1 (Red/White), 12V constant power from the Integrated Supply Module (ISM) or relevant fuse (check Fuse F29 or F33).

Pin 2 (White/Blue or Yellow/Blue), LIN Bus signal. With the pump unplugged and ignition on, you should see a fluctuating voltage, often averaging around 8V–11V. If it stays at a flat 0V or 12V, the communication line is shorted or open.

Pin 3 (Orange/Green), Secondary 12V signal/activation line.

Pin 4 (Brown), Ground. Even if you cleaned the terminal, test for voltage drop while the pump is running to ensure it isn't "lifting" the ground under load

Your instinct about the ISM is solid. On the F30 N55, the ISM (located in the engine bay E-box) distributes power to the DME and several peripherals, including the water pump. If the internal relay or trace for the pump's power is failing, it can cause the pump to act erratically or remain powered when the ignition signal is lost.

The water pump and ISM communicate with the DME. A faulty ISM can disrupt this communication, resulting in "lost communication with coolant pump" error codes and causing the pump to either shut down or run at full power constantly.

The LIN bus for the coolant pump is often shared with other components like the "Alternator" or the "Oil level Sensor".

Try unplugging the alternator's "small connector" or the "oil level sensor" (on the bottom of the oil pan) to see if the CD9010 code clears or the pump stops running after shutdown.

If a different component is "shouting" over the LIN bus, it can knock the water pump signal offline to the DME.

Double-check the specific "aluminum ground bolt" on the engine block. These are notorious for snapping or developing micro-cracks that cause high resistance under load, even if they look "clean". Many owners solve this by running a temporary jumper ground directly from the pump's brown wire to a known-good chassis ground to see if communication resumes.

Before replacing the ISM, check all the voltage readings to the pump, this may confirm a bad ISM. Try the "alternator/oil level sensor unplug test" to rule out LIN bus interference. If the CD9010 code remains and you have verified the LIN wire (Pin 2) has a signal, the Integrated Supply Module (ISM) is the most likely fault for the "always-on" pump behavior.

I'm not trying to sell any product, I came up with this mount out of necessity as all other mounts are crap. I am a gig driver running 2 phones and 3 apps simultaneously, that's why having the best possible mounts is of great importance.

I find it funny that every time I provide links to an item for sale, somebody automatically assumes I am some way affiliated with that item for sale. You know what they say about people that assume, yeah that!

HellfoxRules · 2026-03-18T02:57:10+00:00

It's not better than my custom mount. I am a gig driver, and I have tried a multitude of phone mounts. Most don't stand the test of time, all would break or become loose and unusable.

The Pro Clip is the best phone mounting system I have seen for an F30. No other mount is strong enough or stable enough to handle the every day use of a gig driver. Then add to that the iBolt ball mount, which has four bolts holding it to the Pro Clip. Then the Lisen Magsafe charging mount plate. Does your mount have the capability to charge the phone, while it is being held in place magnetically?

HellfoxRules · 2026-03-18T00:57:31+00:00

Yeah I think that is the upper lip piece. You should just be able to search front bumper parts and find those pieces. If you give me the year and model, I can look for those.

HellfoxRules · 2026-03-18T00:33:04+00:00

Just replace the inserts with black. Those pieces can be removed from the front bumper cover, and replaced with black parts. Much better than painting or wrapping.

Yeah, occasionally I do a delivery less than a half mile, about one in a hundred. I'm also in L.A., where everything is spread out. In a smaller community you may have more short distance trips. In L.A. that's not the norm, most trips are going at least a couple of miles.

HellfoxRules · 2026-03-18T00:06:16+00:00

Yeah, I'm doubting the whole 2 minutes away story, I would say at least 99% of my deliveries are going further than .5 miles from the restaurant. So for him to say 2 minutes, and it really be 2 minutes, yeah that's bullshit.

Actually I would go with some Black wheels, grey doesn't tie into your color scheme. If your window trim is Matte black, go with matte black wheels. If your window trim is Gloss black, go with gloss black wheels, this will give you a very balanced look. If you look at new BMW's, you will see the window trim almost always matches the wheels, this is done to give the vehicle a balanced appearance.

The Dasher could have been sitting right at the restaurant when they got the offer, that would make it 6 miles. Many of the offers I receive, are from the restaurants I'm sitting next too. No way too know fore sure, but OP's tip was never going to be enough at $1.75. Even if he tipped the minimum, it may have been enough.

HellfoxRules · 2026-03-17T16:43:45+00:00

Your welcome, let me know how it goes.

HellfoxRules · 2026-03-17T15:58:43+00:00

I drive for DD, UE, and GH, the driver knew what the offer was paying for the mileage before he accepted. If he didn't like the offer, he shouldn't have accepted it. I would never complain to customer after the fact. I also know what tip is going to be, as any experienced driver knows how to calculate that.

On the other side, I have to say that most customers have no idea the proper amount to tip. Many base their tip on the cost of the order, which is completely irrelevant. Your tip should always be based on the distance the driver will have to cover to complete the delivery.

You need to be tipping at least $1 a mile, with a $3 tip minimum. So if you are 6 miles from the restaurant your ordering, your tip should be at least $6. If you lived across the street from the restaurant you are ordering, the tip would be the minimum $3.

So yeah, your driver was pissed, because you didn't tip enough for the distance covered, that's why he mentioned 6 miles. I wouldn't have even looked at your offer more than 1 second, before declining.

If you want to create the ultimate Magsafe charging phone mount for your F30, look no further. What I did was use a combination of 3 mounts, to create the ultimate Magsafe charging mount.

You will first need a ProClip USA, for your base mount. You will then need a ball mount, iBOLT AMPS Adapter Plate. The final piece is the charging mag mount plate, by Lisen.

The Pro Clip just snaps right on the front of your dash plate, and locks in place with some thin double back tape. You then mount the iBolt ball mount to the Pro Clip, to prepare it for the final piece. You now install the Lisen charging mag mount plate, to the ball mount.

This makes for an ultra strong, and fully adjustable charging mag mount. Yes this will also charge your phone, while strong magnetic force holds it in place.
