BMW 525d problem or not a problem?!
 

Hi all,

yesterday I was cheking the oil and coolant level then I opened the oil cap and WTF this sound appears! Check the video!


Does anyone knows what is that? Someone tells it normal, but I want to be sure before I go to the garage for inspection.

Another problem is, I don't know when this starts to happen but my iDrive don't save any settings I made in it, except clock, date, and settings for lock, light and that stuff.
Radio stations and language does reset when I get from car like for 5 - 10 mins. And it's reseting the hidden menu on the dashboard. I get the lock off, and when I am off the car for like 5-10 mins it reset and I need to do the process always! It very annoys! Did someone had this problem?

I have read of Several people posting up about exactly the same noise with the oil filler off so its is normal yes.

Thank you, and I have read the same but I want to be sure before I go to the garage.

Btw do you know something about self-leveling air compressor?

Self-leveling of E61 is also called Electronic Height Control, Sports wagon rear suspension is equipped with air springs. This device control air spring height to allow the rear of wagon to remain at a stable height to achieve handling stability. The air system (the valve and the compressor) is underneath the real of the wagon between the spare wheel and battery box. The power relay and control module are in the cargo compartment under the spare wheel. If something wrong with the system, a fault displays a warning triangle of message of level system malfunction.

you have serious problems on engine, the chain probably...

Id say its worth checking your engine breather as the loo roll type are bad for blocking if thats what type you have. The self levelling suspension is bad for going wrong, the pipe breaks in several places, mainly beside the jubilee clip at the compressor, the compressor still runs but the car doesnt get to the right height and flags errors, all the while your compressor is slowly dying from the dirty air its sucking in......

Its fairly common noticed it on my E60 525d checked at a bmw dealer and all the other deisels were making the same noise
