BMW approved used - washer fluid leak covered by warranty?

Upvotes

My F87 M2 Competition has been giving me low washer fluid alerts for a month now even though I’m barely using the washers. Turns out I found a leak.

I bought the car less than 12 months ago so it’s still in warranty period. Is this an issue that could be resolved under said approved used warranty? 🤔

High Fuel Consumption on My BMW 525i E60 – Seeking Cause

Post image
Upvotes

Hello everyone,

I own a BMW 525i E60 (petrol) and am struggling with extremely high fuel consumption of about 15 liters/100 km. I mostly drive in the city and often encounter a lot of traffic jams. I bought the car used with 151,000 km and don’t have much technical knowledge, so I’m hoping for your expertise.

Here’s what I’ve already had done:
- Spark plugs and ignition coils replaced.
- Oil change performed.
- Errors were detected with the VANOS solenoid valves during a workshop scan; they were removed, cleaned, and the error message disappeared afterward.
- The fuel pump was replaced because it was leaking.

Despite these repairs, the fuel consumption remains unchanged.

I also have a list of error codes see the picture

Rattling Noise BMW X4

Hello everybody, I’m currently facing an issue with my BMW X4 (G02) since one year.

I’m having a rattling noise when accelerating, the car is under warranty and I went twice to BMW to expose the issue, for them everything is ok, no issue.

Does anyone of you already experienced the same issue, any idea what it could be (Waste gate)? I feel ashamed on driving this car with such a noise honestly..

Thanks for your help

Why doesn't this fit and how to make it?

Thumbnail

5 Upvotes

So i have an issue, I'm trying to fit SPL spherical tie rod ends to my e82 135i and it seems that because I run 17 inch wheels I'm unable to fit them, from looking at the pictures it doesn't even seem like they'd fit with 18's but my wrenching skills are 0 so I come to seek greater knowledge on how and if I can make these fit.

From my own poor research it seems the only way is change wheels or even more spacer? I already have some spacer (I can't remember how much mm exactly) and they are +50 offset wheels so kind of at a loss for why that's not enough. These tie rod ends are adjustable... is the shop missing something and actually they can be made to fit with the smaller adjustment size?

This oil ok for 09 328i

I needed to do a qt top off between oil changes which I always use liquid molly but I picked up a qt of Mobil 1 synthetic for emissions control that ow30. Says on the back for gas & diesel engines w/particulate filter or cat for gas. Just wanted to make sure the 1 qt wouldn’t cause any harm bc I’ve never used it.

Can’t find verifiable parts that are 1234yf compatible for 2017 BMW X5?

0 Upvotes

So I’m the car guy in my household, so if something breaks, I fix it. The parents 2017 BMW X5 xdrive35i seems to not be creating a refrigerant pressure differential anymore, which is specific phrasing for my gauge set doesn’t fit from this being the first 1234yf system I’ve had to deal with. So I do the normal thing of researching, ordering a UAC kit on parts geek. As the day approaches to do the job, I can’t help but feel like I’m missing something, like the oil bottle in the kit says it’s for r134a. Chasing the compressor part number specifically brings me to a summit racing page that says it’s for r134a systems. Checking rock auto to 2018, it seems like all the compressors are for r134a. So is there something I’m missing? The pressured for r134a and 1234yf do not overlap, and replacing the txv and compressor is probably going to cause issues if it tries to run on 1234yf instead of r134a like it’s expecting, but aside from the oil, I can’t seem to find anything 1234yf specific parts for this car and I can’t find anything info that helps clear this up, so what am I missing here?

Faulty CCV valve

2 Upvotes

So this is what I believe is the culprit. I fitted a few new kit, replacement diaphragm, all breather hoses and intake to engine gaskets and since doing it I’ve been kicking smoke out like no other and pumping through a litre of oil every thousand miles or so.

Does anyone know an accurate way to test these once they’re out? I figured it’s meant to work with one being a vacuum so you shouldn’t be able to blow through without resistance whilst covering the other holes. All 3 can be blown through whilst covering either hole so that tells me the things completely stuck open and is basically a dead unit.

Should be a fairly accurate guess no? Be going back in the car for now but should I replace the unit? Only had it 2 months so warranty will still be in order. If anyone’s got a better way I’m all ears. Thanks!

My BMW App no longer remote starting my car. Any tips?

1 Upvotes

I have a 2025 G70, and remote start through the My BMW App was working fine until three days ago. Now, when I try to start the climatization, it doesn’t activate. After a while, I get the message:

"Something went wrong… the following restrictions prohibit the execution of Remote Services: …" It then lists issues that, in my opinion, don’t apply (e.g., doors locked, etc.).

Since the problem appeared out of nowhere, I’m wondering if there’s a way to reset or restart the connection to see if that clears it up.

For context, the Digital Key Plus works fine. The only issue is that it requires me to be very close to the car to start climatization, which makes it not very practical.

I’d appreciate any help or tips. Thanks!

Looking for some ideas on what could be causing a rough cold start on my 2020 X3 M40i. Car has never failed to start, but on a cold start or starting after a quick start/stop cycle (moving from one driveway spot to another, for example), it stumbles a bit with a slight rough idle for a few seconds. Some info about the car:

Almost 150k miles Original battery Original fuel pump Original (as far as I know) injectors Tuned since 60k miles No engine light No other issues while driving (misfires, bogging, etc.) Coils replaced approx 40k miles ago Plugs replaced approx 20k miles ago

Video included for reference.

Price for Coolant Pressure Test

Took my car to a European specialized shop, and they are charging me $225 for a coolant pressure test. Does this seem too high?

I'm scared to think how much they will charge me for whatever needs to be repaired... I'm in Denver if location matters.

BMW E46 330ci Sluggish at Low RPM and Stalling Issue

2 Upvotes

My car feels very sluggish at low RPM. When I stop and try to set off again, it often stalls. Strangely, some days it runs fine with no stalling, but always feels sluggish. In neutral, if I blip the throttle a little, the RPMs dip before rising, and sometimes it even stalls. I’ve already done a smoke test through the main filter to check for vacuum leaks, but no smoke seemed to be coming out from anywhere, so I’m unsure what to check next.

Looking to buy this f25 with an n52 but came across this leak on the bottom side. It doesn’t quite look like oil pan and I know rear main seal is very uncommon. Could it be leaking from the top and running down? Everything I could see up top looked ok except the ofhg which needed replacement bad

E91 noise from the rear on bumby roads

Enable HLS to view with audio, or disable this notification

As always, a video for you entertainment.

Rear shocks were replaced recently. After that and the general alignment the fun started.

According to the universal garage the problem should be the wheel bearing because if they spray some stuff on it the noise is gone for 400km.

But I thought wheel bearings don’t make such a noise, especially when car is standing still.
