I'm not referring to Cruise (C) mode .. but the Auto Cruise function which is the button function on the right hand side of the steering wheel.

1) When driving press the I/O button ... That will turn on the auto cruise function.

2) Then press the +/- to increase or decrease the desired speed.

3) Once you're comfortable with the desired speed press the button No.3 as indicated to 'lock it'. Since the auto cruise will be disabled anytime you step on the brake pedal, pressing this button again will get back to your desired speed automatically.

4) Pressing button No.1 again to tun off auto cruise function.

Hope that helps.

grrr....anyone has change control arm (front) bush to Super PU bush? Quoted to me 3 time of lemforder price. I think the mech being reasonable that i would solve my problem. After 3 months replaced, that bush went koyak again - I hear a "gedeguk" sound if hardly brake to stop. Need 2nd opinion here.

While inspecting under carriage, there is visible leak at the gearbox area. After a thorough look - found that the leak is from engine - gearbox assembly. Its yellowish. Time to change the clutch? Now no juddering, no sign of clutch slippage..SMG system works good.

Opinion please - Read through again from first page of this thread, M-Speed at USJ seems nice to drop by for:-

1. Seal/gasket change out for engine to gearbox assembly.
2. Change of clutch - of course will cover scope 1 above.

I saw there are lots of parts to be removed before the gearbox can actually be accessed. Thats why im thinking, why not change the clutch while they are struggling for only seal/gasket change.

SMG ROCKKSSSS!!! rocking my pocket...rocking my pocket...and i love it anyway!

do you know if the cruise will work if the shift stick in C mode and in +/- mode ?

SMG control unit

Hi there
I browsed through realoem searching info on the SMG control unit. What is the differences between BASIC CONTROL MODULE SMG and
PROGRAMMED SMG CONTROL UNIT ?

hi all,

this is what i did today...damn boring at the office.. So many component on hydraulic connection that could cause leak let alone be a common one, clutch actuator. I believe there are others that we need to look at once our SMG asking to rock our pocket.

here we go...my imagined hydraulic and signal schematic for our SMG by looking at those drawings from catalogue



maybe we start with basic logic first - ECU will:-

-signal the clutch and shift valves to open, to let hydraulic pressure goes to clutch and shift actuator. COndition: input from user intervention (gear level been touched) blablablablablablabla.
-signal the pump to pump more pentosin to hydraulic unit/block. Condition: low hydraulic pressure

come on SMGians! lets keep this thread active..opinions and comments are most welcomed!

Guys, how's the consumption for your 325 SMG?

Great thinking bro :top: and we need more technical people to join this discussion. Funnily enough last week (well misery would be the right word) discovered a leak on my SMG which is severe :-

It's the item No. 1 which is the hydraulic pipe unit which incidently is the only pipe that is flexible, the rest is made of brass pipe

Called Bavarian Auto and they quoted me RM1300 :43: and it'll take around 2-3 weeks to arrive ... Almost dropped my phone when heard that LOL

You can see the hydraulic fluid dripping at the end of the banjo clamp

Because of the angle of the hydraulic pipe is connected to the shift actuator causes the leak at the neck of the banjo fittings. Anyway a picture says a thousand word :-

Leakage occurs at the neck due to the angle where it is fixed.

so there you have it another weak link in our system that can cause leakage. We're trying to work out a solution to it and that means fabricating new parts and a slight lengthening of the hydraulic pipe. Hopefully it'll work lah

Bear in mind though I have not seen or heard anyone having this sort of problem except for me (lucky me huh!)

 

[redhybrid]

yup..the pipe could be easily be replaced....he he.. I think.

anyway, how do you access the pipe? gearbox down? from which angle u took the picture?

It's not easy bro trust me hehe and yes ideally when the gearbox is down for easier access. You can do it w/o bringing down the g/box but the exhaust and drive shaft will still have to be taken down in order to access it.

Finally picked up the custom hydraulic pipe kit :-

I'm extremely happy with the build quality ...

Comparison to the original

Fitted :4:

So far so good the new pipe works as it should but i will check again in a week or two just to be sure. Cost me RM280 not cheap but a whole lot cheaper than paying RM1300 from BMW.

If anyone is interested to get one let me know and if there is enough interest we can organise a group buy i can try to nego for a discount.

Tuan Syed, is this custom hydraulic pipe tested to take the indicated pressure as the original? anyway, it looks strong.

Thank you kind sir :4: That is a very good question and i will ask the hydraulic specialist about it. I would reckon the materials used would be over spec for the SSG application. If my memory serve me right the hydraulic pressure for the SMG/SSG is in the region of 100-146 psi

Will get back to you on the data for the hydraulic pipe :top:

 

[redhybrid]

wawwieee!!!!! i want one! i want one!

10bar is more than enough to kick the clutch/shifter. Summore it is hydraulic with about 1/4" fitting/tubing..most of standard industrial tubing sells at at least 1500psi rated pressure. dont worry about it can tahan or not.

 

[infinityKL]

Im in for group beli
Tq
; )

 

[afazlee]

kudos to b33mer for the effort to save our wallet. count me in if thrs a group buy for this part

 

[geronimo]

hello
my clutch slips i take this photo of the inpa state
957 indicates i need a new clutch?

 

[infinityKL]

went in for regular service and found some hydraulic oil leak under gb...

gb had to come down...

problem..

new part from BA.

fitted..

 

[B33mEr]

Nice! How much did it cost from BA and which workshop bro?

Hehe your underside looks really clean unlike mine lol
