Atacama Yellow 35is build thread

[B21]

It doesn’t look that complicated..they all are variations of drain, new filters, new oil, move the trans through some gear shifts and reach certain temperatures and then ensure excess dribbles out through the relevant hole.

Yes, that makes it sound straight forward. It was the fill/run/fill-more part that seemed fraught with danger to me. This is the thread I read:
https://e89.zpost.com/forums/showthread.php?t=442369 (EDIT: I see this has been previously mentioned in this thread. Still catching up!)

Is it something you are going to do yourself, or have you found a garage with the correct knowledge?

I have a couple of tame local garages…one garage has the MOT capability so since it’s MOT time for the other Zed and oil change I’ve booked both in as a job lot…

Once my garage is built in the Spring and I get a hydraulic lift I’ll do more jobs myself

New speakers for the upgrade arrived today..

They have optimised settings for the DSP..happy days..

How much of a straight swap are those Helix P6B for the footwell woofers? What modding is required?

I covered that and other things in this write up on my 20i minor audio upgrade..basically its a bit of faff..need some O level woodwork skils to help and a soldering iron

Bit of advice on the leaky front adaptive dampers, you can buy remanufactured ones from Poland for about £250 a corner, but they work on an exchange program. This has been on my radar for a while in case it comes up as being required.

Hello, yes saw these guys before, wonder why they only do front 35is suspenders?

Alledgedley there are some folks in Notts that can re-furb them so now they are off, will investigate that, prior to selling them as 'good to go' for those you stick with 35is adapative suspension.

Starting to have a small amount of oil misting on mine now. Did you ever find the company that refurbs in Nottingham? Would be interested to give them a call if you can post their details please. Refurbished ones from Nagengast are actually more expensive than they first appear when tax/customs/shipping is added on.

HI, yes I spoke to the chap, 07877 453936

He wanted £280 each or £260 for 4 at the same time, but he couldn't do the rears anyway..my two rear 35is dampers appear to be non misting / non leaking if you wanted to buy them, Im about to put a lot of old N20 /20i /redundany 35is bits on eBay..

Sounds like a faff, but good fun. I've resigned myself to taking the easy option and paying somebody else to replace the audio. My car has base audio, and it's terrible.

I never had the 6 speaker version but I gather it’s not good..

It’s not that difficult to do a decent upgrade…

I’ve got a DSP/amp setup that would blow your socks off for a reasonable price…(sound of vulture picking over the remains)

However there are plenty of audio specialists …just be aware the E89 is unique and does not share the same audio setup as almost all other BMWs…so make sure he knows what he’s doing with a Zed

The Match one for the 676 you had in your 20i? I couldn't see that making that compatible with base audio would be an easy process. Match don't list any of their DSP as compatible with base audio, so I don't even know if the connector on the back of the headunit is the same. Then there's recoding the car to make it think it has 676 (to flatten the EQ), and the missing speakers it would expect to find, and the factory amp not being there. But I'd be very happy to have you tell me it's nowhere near that complicated.

I've spoken to www.audiofile-incar.co.uk. They have a good reputation and have experience of the E89 too. They are out of my way, but I'll be down in London next month anyway. But again, I'd be keen on doing it myself if it's not as big a project as I think.

[B21]

It’s not difficult, if you’ve already done the journey…the single biggest issue is that in the event that the wiring loom specifics are not there for the extra speakers you will have to lay the extra cables in…but if you were doing the Match 7 for the E89 as opposed to a 3 series you’d be over half way there anyway.

If you are interested best take it off line..to avoid cluttering this thread..the re-coding part is trivial if you have Bimmergeeks Protool..

Unfortunately it is the fronts on mine, rears are holding up well. Thanks for the contact info, very handy to have!

No worries…I wonder if the fronts fail first more often?

Quaife LSD kept both wheels in check with small amount of yoh- yoh through the wheels as they each gripped and then lost it but kept going straight.

Electronic diff / traction control coded out..didn’t try the same trick mid corner…

Just to clarify, does coding out the e-diff leave you with no traction control? I realise the e-diff is effectively traction control, but it would be nice to still have traction control left beyond my right foot!

[B21]

No, tractiion control and stability control remain effective…what’s coded out is that if either rear wheel spins it’s not braked by the DSC system and the engine doesn’t shut down due to that event…if the car starts to yaw (ie get out of shape) then DSC starts to intervene by applying differential braking and /or throttle reduction…

As detailed earlier I bought an Audiotec Fischer Match UP 10 DSP digital amp and DSP tp replace the 677 Top Fi set up in the 35is..

https://www.audiotec-fischer.de/en/matc ... s/up-10dsp

I bought the SDM125 box that allows the fibre optic signal with the audio information from the head unit to be decoded and fed to the DSP/amp

https://www.audiotec-fischer.de/en/heli ... ies/sdmi25

Amongst many other bits I bought a specific BMW to Match 1p cable adapter.

Given the confusing and overlapping nomenclature over names for various speaker positions I was suspicous that yet again, like the 676 Hi-FI version and the Match 7 that was 'plug n play' that it wouldn't all work out perfectly.

So I sat down today for about 5 hours to try and see if the custom cable matched and which amp channel (there are 10)on the DSP was powering what speaker..

Super colour coded spreadsheet later..plus multi meter..

So bottomed it out..as I suspected close but not exact.. most of the audio out of the orginal 677 amp goes via a 20 pin connector.

BUT..the rear centre channel between the seats at head height for reasons only known to BMW comes out on another connector whose primary job is to supply power to the amp.

Quite why oh why they did this when there are two spare connector pins going begging on the 20 way connector god only knows.

I guess, yet again, on the E89 they bodged and existing design to save costs.

AF obviously lost the will to do something about it as the 10 channel amp has one spare channel which would marry nicely with the missing rear centre channel..but they just didn't bother..

I'll work a way to patch that channel across to that connector.

It wll have to wait till the spring / summer when I finish building my garage and then can take the back end of the car apart in the warm and dry..all first world problems..

I very much appreciate the attention to detail here... 10/10
