Car is now a paperweight - DCT HELP!!!!!

EB89 · 12-20-2017, 03:21 PM

Think they will refund what the put in ?

juld0zer · 12-23-2017, 01:26 AM

Mechatronics are a non-returnable item. To replace, it's a box out job as it lives mounted vertically. So labour, some fluid, guibo bolts.

That's very poor of them to not even road test it a few times. I guess it survived the 15 metres out to the carpark?

Do you have INPA or can you borrow someone's laptop with INPA? Try the procedure i suggested.

aaron_ · 12-23-2017, 04:25 PM

From Tuesday till Friday they have me a new hire car at their expense, coded the replaced module to the car (as it wasn’t before), fixed leaks on the transmission pan and drain plug and changed the filter, pulled the transmission out and checked electrical activity on the pins and modules outside the gearbox and inside the gearbox after removing the cover - problem still exists

All that was at their expense

Car is now going to Sylvania Bmw via my specialist Indy for diagnosing at trade prices. Will see how to proceed after I get more info but short of a fixed car this is a reasonable outcome.

As for road test, the problem occurs only on startup. If it doesn’t happen on start up it’s not happening. They road tested approx 30km return and it was perfect. Shit the car down, started it 10mins later and it did it again

As far as INPA goes, I do have it. Tried to use it once for coding my convertible roof. It was too complicated for me so I bought the Carly module. That’s more my level :-)

Will pass the link you sent me to the mechanic juld0zer.

And lastly, mechatronics were mentioned so hopefully it’s not that. If it was would that be intermittent and only work or not work during startup?

Thanks everyone

juld0zer · 12-24-2017, 06:24 AM

The mechatronics is the module they replaced. It is the only available control unit. That's absurd they didn't code it to the car because that's a mandatory step along with any necessary software programming. Usually the transmission does nothing and the GWS may not even light up after a new trans or mechatronics.

Im happy to have a go with INPA if you PM me the details etc. No charge as long as the shop is in metro sydney, i work in Parramatta

Wasn't there a guy who had issues with the harness? I cant remember which forum i read it on.

aaron_ · 12-28-2017, 03:47 PM

Car was picked up and is at the dealer. Last time I was at the dealer they said their computer couldn’t communicate with my car due to aftermarket software (I’m MHD tuned). If they say this again what do I do?

Flash back to stock, but MHD wouldn’t stop that?

Did you have any retrofits like CIC or combox ?

I think It shouldn't. But if he has flashed to stage 0 that means he has an "updated module" that the integration software mightn't like. DO you have a backup of your stock tune ? Flash back to that perhaps ?

aaron_ · 12-28-2017, 10:16 PM

It’s been okay so far. Diagnosing is no problem - the potential problem could arise if reprogramming is needed and fails. If it does, I’ll do a full 40min flash back to stock via mhd app. That should work. But hopefully it’s not needed

Dealer updated me just now. Said either wiring or module (which I already knew). Won’t be worked on now until Tuesday but happy they’ve started. They should be able to fix it. If not The M4 (or 650i depending on funds) upgrade might happen sooner than I’d planned :-)

N55 doesn't allow you to backup

Surely you Should be able to flash the correct ZB

aaron_ · 12-29-2017, 08:48 PM

It’s all hypothetical right now. We’ll see next week if they determine it’s a programming rather than module/wiring issue

But it’s been 3 weeks without a car now. I want it back!!

e36mmm · 12-29-2017, 10:49 PM

Oh I can imagine the frustration mate. Sucks not being able to drive it. I'm sure it'll be sorted soon and back on the road for you to have fun in it.

juld0zer · 12-30-2017, 02:22 AM

I'm still urging you to give the INPA 'refresh' a go.
I had a cruise control failure message and the fault was due to the DME expecting a road speed signal from the DSC, pretty much the same as your type of faults. I had several of them indicating a communication fault.

I went as far as swapping back DSC modules (because it only arose after fitting and coding a used DSC module) and running a new wire from the DSC to DME for the road speed signal. This was after all the other diag steps, reprogramming the car with ISTA/P and everything. Even in ISTA/D it doesn't have any guided troubleshooting, test modulea etc for this type of fault. It just tries to tell you more about this type of fault and how to interpret it.

I will be back next week if you want to try it.

Oh, one more question - does MHD have a specific map for a DCT, auto, manual car or is it one map for all N55?

Aus335iguy · 12-30-2017, 04:48 AM

^This guy's a pretty good beemer accredited tech. I'd listen to him.

I did read through the link you provided. From what I understood the German text you reset didn’t apply in my situation. That being said 99% of it went over my head.

My car is at the dealer (Sylvania BMW) now and they’re closed till 2/1/18. Maybe you can do it via a remote connection?

Also my mhd tune is a twisted tuning custom map.

juld0zer · 12-30-2017, 07:06 AM

Yeh it's not exactly the same as yours but the type of fault is the same (expected message from another control unit not received by DME).

I won't be able to do it during work hours, it would have to be after work. Otherwise i can give you the directions to access the menu and you can go there and give it a shot. If you are on good terms with Sylvania I'm sure they won't mind, especially if they are stumped.
You will need to have access to N55 DME on your copy of INPA though. By default it does not support it but there is a guide online that will tell you how to add N55 support.

Have you been liasing with Twisted Tuning about it? Maybe they could give you a new map to try?

Thanks for the offer, looks as though they’re not stumped. Ruled it down to 3 possible items:

Mechatronics (fml - 10k expense)
Loom into gearbox
Loom inside gearbox

Will have an answer by Monday arvo it seems

On the plus side, I have a 2017 bmw 125i as a loan car (1000km). Goes pretty hard. I like it :-)

Loom into gearbox is my bet.
I thought the TCU and Mech unit is sold as one ?

MJ80. · 01-04-2018, 02:29 PM

10k?

e36mmm · 01-04-2018, 03:26 PM

Can a tune by mhd actually cause a problem like this?

Fingers crossed you’re right

No idea if tcu and mechatrocs is one unit
