Hey guys I have a 2004 m3 with smg and for the past 100 miles the car shutters from a stop. The car just hit 45,000 miles. The problem only come when the car is warmed up and I have done the smg reset witch helps for a second but then it come back. Please help me fix this problem!
Ok if you own a SMG M3, you should always have at least 1 spare salmon relay in the car at all times. you can get the relay at any BMW dealership, but I would check around and get it at the lowest price (including shipping & tax).
Now to address your issue. Will a clutch adaptation learn-in fix your problem. Yes, if your problem is clutch engagement. Maybe or no if there are other issues. A SMG clutch should last in excess of 100k miles under normal usage. (now anything man made can fail at any given point in it's life span) Check your regional forum section for someone with a INPA/DIS/GT1 computer that is willing to do a clutch learn-in. You're going to need a heavy-duty battery charger also.
The cost will be based on the hourly rate of whomever is performing the work. A fanatic might charge you $60 and a dealership might charge you $250 ( all prices are guesses as I don't know what the person performing the work's hourly rate is and how long they perceive the work to take.)
Hey, first post ever, thought I'd give my 2 cents.
I drive a 2005 M3 SMG and I've been having this same shuddering problem. But mine has ~72000 and it shudders when it's both hot and cold. I took it to my mechanic (we are very good friends) and he said it needs a new clutch, but I can wait a little longer before changing it. He said it will cost about $1500. Not the greatest news, but I trust him. This could possibly be the same issue for you.
Usually a new clutch isn't needed. The clutch needs to be re-learned (adaptations). Sometimes it's the slave cylinder. Very seldom is it a damaged / worn out clutch until you're closer to 100k. But failure has happened before 100k.
Also, if he replaces the clutch, the relearn process has to be run after installation to ensure proper inital engagement.
Ask for smg clutch teach in. this will let the computer know when the clutch is engaged. same as when you would drive a manual and feathering the clutch. The teach in will let the smg know how far the clutch is until full engagement. Where as the manual you can feel it and start pressing the accelerater
I have only done it once when we swapped over to the CSL SMG software. Before that I had 68,000 miles with nothing more than a soft reset done.
Hope that helped a little. At any rate, as long as something physical isn't messed up, you should be good for a long time after you reset... If you go through all of that though, you may as well do the CSL flash.
You shouldn't have to do it for a while under normal driving. But it doesn't hurt to have it done every couple of years if you drive your car aggressively.
You will need a battery changer when performing the process.
Hello guys, today I went to a fellow member and he preformed 4 thing on my car with his autologic. Fully adapt the gear box, teach clutch value valves, teach in clutch slip point,reset the clutch characteristic curve an I think I'm not sure he did a teach in of the longitudinal acceleration sensor. My problem is now the car when changing gears jumps 500 rpms when up shifting with out letting off the gas. What could this be? Also was it wrong to do these thing all at once? There is also another problem. When engaging 3 or 4 gear the clutch slips or dose not engage well. Pleaseeeee help me out I'm worried that I have messed up my car. He told me that all these thing will get better once the car has adapted. I hope it's true.
I had a very similar result when I did this process with my AE for the first time. I found a thread over on m3forum.net where the op had the same issue. I did what he posted as the solution and my car has been shifting perfectly ever since.
Also at the time the suddering and jerkiness started a vibration type of noise started coming from the transmission or around that area at 1900 rpm. What could this be?
