My FC on highways is 8.2km/l while city+highway is 7.6km/.
My average FC is usually above 500km per tank.

 

Zig,

I thought your FC is very good for a 530i. Mine average up till now is 7.8km/l or about 500km per tank.

Remember you tried out driving on manual mode and achieved 10km/l right?

I am still wondering if we really pump one full tank and drive the car in manual mode, is the comsumption really lower? Of course, we have to assume we change gear at the reasonable rpm and not pulling the rev.

 

Haha you guys are funny. On my iDrive it says 11.4L/100Km.

Going to PML Kg Arang tomorrow, to get rid of seat creaks and screeching brake. I was reassured during my last servicing that the creaks had been caught, and brake noise will go away once I changed the pads, but $400 spent on new pads the brake still screech, and louder some more. See how tomorrow, but I must say Dennis is very proactive, just mention Wing Flap gang and everything is arranged swee swee.

 

But we are measuring Km/l. So 11.4L/100km is actually 8.8km/litre right? So if you top up 60 litre of petrol, you can clock 528km which consider good FC right?

 

mine is around that range.....funny...how come i only bother about consumption after nearly 3 years? All because of the wing flaps gang!

 

Still cannot but I'm gonna cut and paste below.


Dear Edward,

currently we do not have any M5 with which we could do any comparison. I would also like to
experience the the behaivior on other M5`s, but basicly I also have no reason not to trust my
collegs in Germany, when they give me any information!

Best Regards
Torsten Simon

Good afternoon, gentlemen. It has beenquite a few days since I last sent the message below, but I have not even received a written acknowledgement from anybody.

Appreciate receiving some indication that my case is currently being investigated.

Thank you for your response, Mr Torsten. However, I am not convinced.

Firstly, why does everyone else in Europe and the USA not have the same observation as me? They are in much colder countries.

Secondly, why has the high idle reared its head after 6 - 7000 km and not before? Why is it when PML reset my car the idle settled back to 750 rpm?

We are living in a country where the temperature is constantly high; in the region of between 32 - 34 degrees centigrade. I am quite sure the temperature at the exhaust is very much higher. I idled the car for half an hour just to test your explanation. We all know what this can do to the temperature; the idle did not recede to 750, so your theory goes out the window. Also, to rebutt your explanation, when you drive fast, more air flows "down there" and thus cools down the cat converter.

Please, I have respected PML (Kg Arang) and BMW Asia for their expertise so far. I don't think I am well read enough to totally dispute your explanations, but is there any case study that your M Division has to offer? Is there any paperwork to back this explanation? Have I, once again, made a wrong choice?

I have a 545 with problems that PML and BMW took more than a year to resolve, which still shows intermitent problems and an M6 that is now showing problems (as far as I am concerned) that will probably take alot longer to be resolved, if at all. All in, I have spent a stunning SGD 800,000.00 before options Buying More Worries. So much for my misplaced faith.

Dear Edward,

I got the answere already last week, that the behaivior of the car is ok, due to the following reasons:

The engines of M5 and M6 adjust their idlespeed by their own in dependence of requirement.

The requirement area`s are:
1.) Charge condition of the battery - increase of the idle rpm when alternator need to deliver more
current
2.) The catalytic converters need a specific operation temperature - increase of the idle rpm when not
hot enough under certain circumstances.

I think No. 2 is that what happens in your case. When you cruise slowly the catalytic converters do
may not reach their operation temperatures. While you are driving faster with more "throttle" the
catalytic converters reach more easier their operation temperatures and the increase of the idle
speed is not requirered.

Sorry for the delay from my side!

Best Regards
Torsten Simon

Good afternoon.

The high idle has begun again. It happened at 9905Km whilst I was at the Singapore Customs at the second link, on the way into Malacca. It has since been behaving like it was before PML "cleared the cache" the last time round.

Mr Torsten, do you know of a cure or maybe M Division has come up with some antidote at their end?

Please do not ask me to send my ride in for more testing without answers again.

Thank you.

Leslie,

Let's not try out-rank each other. I take a look at the ranking system and almost laugh my head off. You tot senior member sound very senior right. People like Tategoi is a veteran member and higher up like LMK is an Elite members. Our big bro Ed is a Specialist!! I wonder what's next after a Specialist.

So a senior is actually like a Private in the army (luckily we are not a recruit). By the time we become say an Elite Members, most of our wing flaps gangs will already be either Specialist or Scientist or maybe Nobel prize winner!!

So let's be good boys and take instruction..o.k?

Cheers!!!

 

I managed 10km/l in only in manual mode and very gentle on the throttle, upshifting below 3000rpm and keep the gears high when cruising. I did that out of curiousity to see how far I could stretch the car.

 

i am not trying to add oil into fire but from the tone of the reply from Torsten, he is just "unprofessional" about it.
instead of trying alternatives like isolating the CAT by removing the sensor or change a sensor if he thinks it is the CAT problem, he is insulting a customer intelligence.
On top of that, there are many reasons for high idling..gearbox sensor, flywheel, engine temp etc.....why only so simple???? A Cat? We all know, a diagnostic computer may not be always correct.
He has no reason not to trust his colleagues, but he has a bigger reason to trust someone who feeds his mouth and family by spending $800K! And a bigger obligation to make this cusotmer happy!

BMW Asia....a failure to customer satisfaction for this...
