SMG Share thread

[redhybrid]

hi beemer!!

can share some screen shot on the bleed procedure for SSG hydraulic system using GT1?

heee....i see u got ur K+Dcan interface.

 

[afazlee]

Let's all SMG guys go for the official TT at Borneo Rainforest this week, i'd be thr about 10pm.

 

[redhybrid]

afazlee,

hows your SMG doing? boleh tumpang for TT??

 

[afazlee]

mine ok lar not bad. still enjoying every bit of my daily ride. for the the price paid i think it was a steal to have that hp of german tech on d pedal. can tumpang 1 no problemo, on the flipside why don't U give us a ride on yer spanking new ride redhybrid. dh dapat belum? n btw d thud sound during gear shift adds 5hp to the kick ;P. come to TT lar n meet all the forumers.

p/s : crap, missed that ESS TS2 SC at the classified

Looks like I finally have the dreaded SMG problem.

Unlike with the 325 SSG or SMG1, on the M3 the problem is more likely to be (fault code 056) the SMG pump or the pressure accumulator and sometimes the SMG relay.

Initially only the transprogram/smg light will appear on the cluster when some hard driving is done, and it will be appear in more regular fashion till occassionally it will pop into N, before going back to the proper gear. It is an indication that the pressure cannot be maintained either due to the pump or the accumulator which is actually a pressure tank like those you see in a hotel water pump room, where the usual cause is the diaphgram failure.

I am going to swap an accumulator (21532229716) and see if the problem goes away and I hope it does, or else it will be SMG pump unit (21532229716).

afazlee, not yet lah... orang gaji kecik like i am, loan susah sket nak approve, and finally, i will be getting my UDM by end of next week if there are no issues at JPJ/PUSPAKOM.

Sorry geng, cant join TT lah. I got RedBox session with officemates, bos treat!

Cheeers! have fun on TT tonite~!

hello smg's ...

car shakes a little(ass feel) at cold starts for about 45sec to a minute, warm engine no problem...

diagnostic - no fault codes.

anyone wt this experience?

hi,

anyone having the same problem like mine?

whenever we unlock our car there must be a long long buzz right?
and when we stop in traffic or when idle the buzz will keep coming.

my current problem that im facing is, instead of a long buzz, it goes really really short and buzz like 3-4 times when its idle every minute.

got any idea what cause that?

run a check at Ab JB and also another workshop show no error.

pls help.

thanks

Finally, she's here!

Got to change outside temperature sensor. Climate Control went south. Its trying to work when its raining outside by giving below degC in which heater comes into play! hott!! (anyway, already got discount for that).

Everything else, works fine...

Bro which workshop do you bring your car to for your SMG problems ?

It can be a lot of things really one of the possibility is the O2 sensor, check out the the link it seems this one describes the problem same as yours :- http://forum.e46fanatics.com/showthread.php?t=740426

SMG pumps will turn on to pressurise the hydraulic system in which the accumulator job is to hold that pressure. If it leaking then you will hear the pump turn on more often. Seems that you have the same problem as Albundy. I'd suggest whenever you're in KL give gearbox specialist M-Scope a visit or Ah Wai at BM World desa tun razak (he's done plenty of smg but it's not cheap i warn you)

Item no. 1

Checking in. Hi B33mer

I need to stop worrying about my 325Ci SMG 'characteristics'. It is running fine, getting a transmission oil change on Friday. The only thing I have to say is when the engine is cold, every now and then it shudders between 1st and 2nd as if the clutch disengaged before the revs were high enough. Once the engine/gearbox oil is at operating temperature it doesn't do it. I believe this to be normal.


It's a bit like when you have a headache so you research on the internet and suddenly it's a brain tumor!

I have been sending both my rides to this shop called Autobahn in Sunway. This chap used to work at Heritage. His rates are very reasonable compared to BM World, and a friendly chap.

As for the SMG issues, there is nothing much one can do. Just hope the culprit is the pressure accumulator. The problem is intermittent as of now.

Bwahahaha so true about the research thing lol ... Nice seeing you here bro :top: Do an intro about yourself in the newbie section that way we can welcome you to our forum proper :top:

Yes i've heard about Autobahn it's run by a chap name Tan ... Will visit him one of these days, thanks for sharing :top:

it was a very bad traffic at federal on way back from subang. pehhh....in 1st gear for almost one hour from hilton up to midvalley. my car was moving like d driver is having first driving class.

the thing is, i think it is not normal..like 2 or 3 times, when i accelerate a bit, release and accelerate again, very bad 'kluk' sound from engine bay.

anything that i need to check? i hope its not yet the time for a new clutch actuator...

sorry, was bad in explaining.

 

[Gravity101]

I got the trans and diff oil changed today. As soon as i started the car and shifted from N to 1 it felt smoother, quicker and sounded quieter. Driving was definitely smoother/quicker. Still has the characteristic noises for the SMG transmission but this is just the sound of the clutch, etc.

Also had the suspension control arm bushes changed as after the mechanic drove it and found it was knocking when he went forwards and backwards a few times. All up cost me AU$506

 

[Gravity101]

Crazy idea......AFAIK both the non-M3 SMG and Alfa Romeo (Selespeed) use magneti marelli, so.......Are the sequential parts or even some of them interchangeable?? If so perhaps the Alfa hydraulic actuator is cheaper than getting the same part from BMW. If the hardware is the same then perhaps all that needs to be one is to swap the circuit board. As I said, a crazy idea....

 

[infinityKL]

It cost about the same here.
This country is crazy when it comes auto and parts

hi albundy,

how much it cost to change the item you mention?
and does the problem solve?

beemer,

thanks for the great advise!
just dont dare to simply go any so called bmw "pro" shop anymore.

headache

anyone wt this experience?

Finally it broke, sat morning start car, rpm dancing till engine die.
Had to try few times wt more throttle till engine a bit warm.
Drove to mech, diagnostic - no fault codes. (still wondering why)
Anyway, we attcked the ICV straight away and true enuff it was jammed.
Gave it a good clean service. All good. Cold start shaking also gone.
Infact, the usual jerks at cold start gone.
Basically no more need of warm up, just start and go now.

Happy man
