Have you had it in for any of the computer updates? This is a fairly common issue on 08's. You need to take it in for the TCU updates.My 08 Passion has 22K miles. Doin fine until just recently & occasionally it does not want to go into Reverse & sometimes Drive. Need to see a dealer?
back in early 09 they put out a campaign where all of us 08 owners went into the dealers and got the 2.0 upgrade. Since that day, service centers have disavowed any knowledge that there was ever an issue with the TCU programming.... even though the current programming is somewhere above version 7.2 (This is what was loaded in my old smart back in 2011).how wound one knows when to do the software update?
You really don't know. MB/smart isn't exactly vocal about software updates. Usually it's folks posting on here that they got one when in for service.how wound one knows when to do the software update?
That was the original 2.0 updated. I believe there have been at least two or three since then. I had the 2.0 done, but haven't had any issues since, and haven't been back to the dealer since. I flipped over 158K on the way to work this morning, I figure if any software glitches were going to surface, they would have done it by now...Update was for the 2008 and early 2009 cars.
I'm not doubting your word, but I find it VERY hard to believe that ANY dealer would "service" the actuator rather than just replace it !!!There is a thread somewhere that goes into the clutch actuator being jammed up from old grease. This makes sense here, because a new clutch disc will inot help the shift in reverse problem if your clutch can't engage and dis- engage. I have this same problem of an intermittent failure to shift into R after my smart sits for too long. After I fiddle with the shift, eventually it operates fine, and as long as the car gets used, it doesn't fail to shift.
I have a 2009 Brabus. It's had that update, of the TCM AT THE DEALER IN 2010 I think.
Since then I have had DP TUNE re flash my ECU, AND TCM. No problems with that, and now after a couple years this failure to shift came around. So, at my 40 K service, after reading those old threads, when I went into MB smart Houston north, I told them about my problem, and they said this is a common problem, and re flashing the TCM FIXES IT. Well, I hired the dealership to just take my actuator apart and just grease it, and NOT TO REFLASH my TCM.
They did this and I will let everyone know how it worked. I have a strong opinion it will help, just because of that thread about a crusty actuator, and how it works.
Maybe someone can add the link to this thread here.
Hope this helps, MB Houston was all about that TCM update. I love the DP TUNE update, and it didn't cause any problems before, and the weak link has to be putting the clutch IN before the shift, and it wouldn't shift in gear on a manual tranny car, if you didn't depress the clutch pedal, so why would a smart shift into gear if the clutch WAS engaged??
Get your actuator disassembled and greased, like I did, and see if that helps. This is preventive maintenance and they charged me $149 for this service. If you don't have yhe update,get it done, AND have them grease the clutch actuator as well.
