Big Bangle Booty - 635D

Some more petulance from the 6 series. Since purchase I've had sporadic 'High Power Consumption' alarms when first turning on the car. It seems fine, I've left it 2 weeks without use twice while on holiday and it fires up fine, so I don't believe I have a big battery drain.

Last year I had the battery replaced which didn't remove the alarm, now I've had the IBS (Intelligent Battery System) cable replaced as it was assumed to be that. No joy - alarm persists?

I think I'll live with it.

Furthermore, an oil leak from the swirl flaps area has killed the newish glow plug module - garage recommends blanking these now.

I deleted swirl flaps on my M57 35d and it wouldn’t regen. I replaced the manifold.

I’m going to assume the above resolved the issue. My question though is why …

Swirls flaps were leaking. I deleted them. Then the dpf blocked and wouldn’t regen. I fitted a new manifold with flaps and the dpf regenerated fine. My thoughts are that the flaps are necessary for an effective regen. (This is my experience, others may have removed flaps without issue).

DPF not regenerating would indicate something else, not really swirl flaps.

It's usually the thermostats, car not getting to temp and then the car doesn't regen.

Had the same issue on my M57 35D X5, having no coolant gauge doesn't help, using the 'hidden menu' will give you a reading, I have bought an external OBD2 gauge to monitor levels and a multitude of other items.

The thermostats were fine as were all other variables needed for dpf regen.

I’m glad your issue got resolved, but from my (admittedly limited) understanding I have trouble relating these.

I had a leaky manifold, whereby oil was drenching the side of the block. I took the manifold off to replace seals and was not overly impressed with the state of the flaps. I should mention that my previous 03 530d had a flap failure, which led to a very unhappy engine. Current steed 07 LCI 535d has the “updated flaps” apparently, but as I said looked a bit sorry for themselves, so I decided to blank them off.

Probably done 10k since and regens seem to be operating. I thought the flaps were closed at idle and opened as revs increased, so that at regen speeds they would be open. From memory regens depend upon (this may not be accurate)
Coolant temp
Speed
Amount of fuel in tank
Lack of limiting fault codes

I have had regen problems in the past but they were always resolved by changing the two engine thermostats. I think I’m on my 3rd set currently and about to change them again.

Glad yours is sorted and regening okay. Lots seem to without flaps. I’ll stop talking flaps as don’t won’t to derail the op’s thread. The M57 is still fundamentally great!

If the op does want a swirl flap delete I have my deleted manifold on eBay. This title may find it: BMW E9x 335d M57 Inlet Manifold Swirl Flap Delete 11617800585

I have to agree. I don't doubt your experience (both with your car, and many more BMWs than me!) but it's not something that I can understand based on the functional description in TIS, unless there was also some error logged that was causing the issue?

My wifes M57 X5 has the swirl flaps blanked off (personally not for me, but it came that way) and it does regens - although it did arrive blocked due to bad thermostats and needed some cajoling to regen.

Was the battery coded/registered to the car?

I have, at least within the confines of Carly. In there you can register existing or new battery - I re-registered the existing. I've got a 95aH AGM battery fitted, I could select 90aH or 115aH I think it was - so went with 90! There is no selection on there for the type of battery (i.e. AGM or the older type?), but I'm unsure if that would make a difference.

This was the battery info on Carly - the cars used most days, it seems like the majority of charging was between 70-85%. Again not sure if that's normal as it'll get a good discharge initially starting the car each morning?

Just as a FYI carly states it can register batteries but it definitely does not register it properly.

Great read, very similar story to myself with my 07 635 conv, indoor puddle caused by blocked holes in fire wall, all clear for 6 months then more puddles every time it rained, it appeared one of the rubber strips at the bottom edge of the the roof was perished needs replacing, cheers BMW £700 for a 2ft strip of rubber!! + fitting

Got the car with 33k miles now on 123k, had new battery which as mentioned has to be tied into car ecu.

Only issue i have is the SOS thingy is not working so everytime i start i get a warning, been to BMW and advised it is a 6-9 month wait for the part and approx £600 + fitting!! not sure if a 2nd hand unit will work.

Alot of car for the money imho and in the future i would like to test drive a 640 gran coupe so the children can sit in the back.

Keep the updates coming

Interesting, I've done some reading after your message and found the same. So really, I still need someone with the proper tools to register it before I can rule this out.

I must say, Carly seems a rip off - it auto renewed with no warning this year for £125 I think it was. The main reason for purchasing was to adjust the number of indicator flashes on my wife's X1 and it failed to do that.

I almost went with carly, that annual fee put me right off.
Your car is a belter, I have the same interior in my 630, with the same seatbelt and door seal dirt, I'll try the lint roller.
Have a look at bimmer link and code, see if they will do the battery.
There are some electronic wizards on e63/64 facebook page.

Yes, luckily I got carly a few years ago when it was a one off fee. I still don't think it's brilliant, luckily I managed to code a few features for people to claw some money back and it costs me nothing.
I find it useful for reading error codes but even then some of them don't correlate. A few people I know swear by the foxwell 510 unit which I may buy as a back up.

Recently just bought a 635d to sit alongside the V10 M6, just had swirl flaps changed and luckily timed it well, car was only on 106k. Thermostats seem to be opening and using the trip reset my last few runs on the motorway have surprisingly returned 45-49 mpg. Which I didn't think I'd achieve.

Plan going forward is a full service in 8k, and also to do the gearbox service along with the additional filters. Do you happen to have a link to the filters you bought? I will also look to blank egr and cooler and have it remapped

Yeah, its a rip off and the auto renewal is a killer. I had a tantrum when I was stung the other year and complained that there was no warning email prior and they basically said tough st, they're not obliged to so ps off.

I had exactly the same conversation, they must send that email 100 times a day. Immediately asked to cancel next year's renewal lol

Minor milestone today of hitting 90000 miles, driving down the M3. So roughly 35k from purchase in a year and a half, not bad going!

[CornedBeef]

Thorough clean today, and showing how Carbon Black can look completely different in the sun!

It's had a service by me as of last weekend, I've essentially lined up the oil changes with it hitting each 10000 mile interval now - next will be at 100k which will be around Christmas time.

Gorgeous colour, what a pop!
