Hi Andreas,
Not sure if this is the right spot to ask a question regarding my 2012 Bmw X1 N20 (Canada).
At idle, when outside the vehicle, you can hear a…. hard to explain….kind of a ‘rotational thumping’ or ‘soft knocking’ noise that seems to be coming from underneath the car. The thumping happens maybe 2 times a second and isn’t perfectly consistent in intervals.
I had the BMW foreman listen to it and he wasn’t overly concerned but I feel it has gotten louder since seeing him and it’s just driving me nuts even if it’s not a serious problem.
Any ideas?

I would have someone lift up the car and listen from under the car while it is idling and see exactly where the noise is coming from.

Dear Andreas,
maybe you can give me a short estimate from your point of view:
My F13 /650ix with 77.000miles makes a squeaky clunking noise by low speed over bumps or bad roads from the front left side. It can be also repruduced when the cars is pushed down in the front. Then it can be heard in the engine bay in the area of the strut bearing when the car rebounds.
This nois can also be heard sometimes directly after i stoped the car on a trafic light. Then it makes two times “clunk clunk” from the left front side.
We have allready changed:
Wishbones
Trailingarms
Sway Bar Links
Track rods
My workshop suspects the EDC Damper. This is for the front very exepensive (2000 Euros) 😦

Hi there BMW tech,

I have a 2014 F11 LCI 530d
I have just replaced the front pads, the job was simple and fun but now after finishing the job, one side of the car is sitting 1.5cm higher than the other.
When I did the pads, I jacked up the front of the car using the subframe and then i placed jack stands at the jack points under the door sills….
Have i possibly bent the subframe or something? Any advice would help?
LikeLike
This doesn’t make any sense,,,,I don’t think you bent the subframe,,,,are you sure you didn’t jack the car up on one of the front suspension arms?,,,,,also take a look at where you jacked up the car on the subframe,,,,look and see if you put a dent in the subframe,,,,,question for you did you loosen the front shocks by any chance.
LikeLike
No dents on the subframe where I used the jack. I jacked up using the point of the subframe that pokes out underneath the car with the hole in it….. I did a fair bit of reading around and this was identified as the place to jack the front up from.
100% sure I didn’t jack up on any arms or suspension components.
I used a trolley jack under the middle of the front, then placed jack stands under the left and right jacking points.
When it came time to take out the jack stands, one side was able to come off after about two pumps of the jack, the other side took quite a few more, say 5-6…. that’s why I’m worried. Yes both jack stands we’re set at the same height. I was on level ground (as far as I can tell, it was on a concrete slab in my barn) and yeah, it was only after I took the car outside I thought “Jeez that’s weird”
After closer inspection one side (front and back) is sitting higher.
Any ideas?

That could totally be it I hope. Maybe when I was pulling on the caliper to create room for the pad to clear the rotor this had happened and it’s popped out, 1.5cm or so would probably be the amount it would be out maybe….

Thanks for the video,,,but it’s hard to tell if they are bad by prying on them,,,,even the new bushing will move around when prying on them,,,,,what you have to do is look at the bushing and see if any black staining is on the bottom of the bushing,,,,them you need to look at the side of the bushing where the rubber is,,,get a flashlight and shine it at the rubber part of the bushing and see if there are any cracks in the rubber,,,you can use your pry bar at the same time to get a better look,,,,if they are cracked or broken or fluid stains on the arm then they are bad.

Greetings from Australia. I have 2006 BMW X5 3.0D, 230,000Kms. Car went into limp mode, engine running evenly, no misfires at idle, but no power. I can hear the turbo spinning up, so probably OK. Lifted the engine cover and found 20mm hole burned through the intake manifold, just by the firewall. Car starts and idles OK!

Hoping you can point me in the right direction. 2011 E70 Diesel w/ adaptive suspension. About a month ago, I drained and refilled the Power Steering reservoir. About two weeks later, it got very cold here (I’m in Minnesota) and on cold start one morning, iDrive showed a steering warning for low hydraulic fluid. I popped the hood, and the top of the reservoir was covered in fluid. I assumed the gasket on the cap failed. Replaced the cap, problem persisted.
This has been going on for a while, to the tune of a bottle of CHF a week.
I first tried the old fashioned “jack it up and turn the wheel a bunch” method, assuming it was just air in the lines. Lock to lock for several minutes with engine off, until no more bubbling was present. Cycled engine a few seconds, and repeated several times. No cavitation and no leakage. Drove it for a few minutes, and CHF clearly leaking out the bleed on the cap.
Swung by the shop to see my Indy one morning. We learned two things: On startup, flow from the return into the reservoir is VERY aggressive. If you start the system uncapped, it will spray everywhere. If you start it, let it run for a bit, you can remove the cap, but it’s very turbulent in the reservoir. We looked at a 7 series with adaptive suspenion, and there is almost no fluid movement in the reservoir when running, even on a cold start.
I have tried vacuuming down the system repeatedly, even applying vacuum while running. It generally gets to the point where there are very few bubbles, but once I take it for a drive, the leak returns.
I ran the recalibration for the system in ISTA. It seemed to eliminate the aggressive return, and when I checked the reservoir, all looked good. Upon driving it, the problem persists, and the excessive flow back into the reservoir is back. I vacuumed down the system again, got the fluid level set, and then ran the calibration again. Same result.
Next thought is to change the reservoir: it could be the filter is clogged, so the system is starved for fluid, trying to compensate by boosting return flow, or that something which is to regulate the return flow in the reservoir has failed. The system is not storing any meaningful codes, just the code for low fluid. The proper procedure for start-up calibration is to run the vehicle w/ the harness disconnected from the valve block, turning the wheel lock to lock for several minutes, then running the recalibration. I have yet to disconnect the valve block harness. I’ll be doing that this go-round when I replace the reservoir.
Any other thoughts or things you think I should have my Indy take a look at?
LikeLike
Ok is the CHF fluid flowing out the top of the reservoir cap almost like a volcano and is the CHF fluid foaming?,,,,if it is and what it sounds like your power steering pump is cavitation internally which will cause this problem.,,,,,the only other problem we have seen only one time was a power steering hose at the steering rack collapse inside causing a blockage but what happen usually the hose will split open causing a major leak from the bad hose,,,,so I don’t think that is your problem,,,,,I would think your problem is more like the power steering pump

I bought a brand called VDO Continental which they said is the same brand in the Genuine package.

I been doing plenty reading about the 328 and 528 and it seems there is a massive issue with the design of these valvetronic system. So do you think i should just go ahead and purchase the shaft and bearings along with another motor to just have him do a complete change? He also showed me that the motor is wired to the ECU and it could also be an ECU issue. What do you think on this?
Another issue im facing with the vehicle is the fan. The fan isnt spinning how it should. There are times it spin but most of the times it doesnt spin. I ended up buying a fan and we are having the same issue. When we checked the fan harness the live and grounds gives a reading however the small activation/signal wire is reading up and down (mostly 0.2 and and rarely goes up to 1.2 then back down). We checked another 328 in the shop and its activation/signal wire reading is constant (1.2) so we are thinking there is a problem with wherever this wire comes from. Any thoughts?

Help, I own a bmw i3 Rex 2014, I was suspecting a low capacity high voltage Battery, so went to dealer and he performed battery capacity test (the short one). The test show good battery. I wanted more information but he couldn’t tell me more (% of lost, remaining battery life, etc.), the test show enough battery capacity only. So I install ista-p on my computer and run the full battery capacity test (10 hours descharging and charging), at the end of the process, the computer tell my it need to write the result to the SME and need to stop the high voltage contactors switch in the SME and start a countdown of 15min and do not disturb or stop the comptuer because contactors are off. After 7 min. the contdown stop and never went to zero so I cant’ finish the process, Now my car is “brick”, I have no voltage from the high voltage battery going to EME or everwhere else, because SME contactor switch are still off from the failed countdown. What can I do to restart the switch? I tried each test plan without succes except battery change. The only thing I saw that could possibly help me is to do a battery restart, witch involve a BMW EoS tester that I don’t have. Do you know a tip to restart the high voltage switch? I saw in SME that the contactors are still of but I can’t trigger them to on.
Your input or question are essentiel for me, I can go to the dealer (towing) but need to tell them what I did and where to start looking because my dealer is a new “i” dealer and don’t know well I3.
I still don’t understand what happened and why the computer stop working, I used ista a lot to do tests and never let me down.
