Ok so I have been using this car (2008 smart fortwo)for 2 years now with no problems (except for my headlights bulb always burning within a few months)

IN the last week my car is not acting too well. Basically one cold morning I started the car, put it in reverse, ....it indicated it was in reverse, but the engine just revved up with no motion. Put it in Drive, it indicated Drive, and no motion forward, ....the engine just revved up again. As I am in quebec (-20 sometimes) I thought ok...its cold I'll wait till it warms up. TO no avail. I shut it off and retried. didnt work.
Shut it off, put it in Park, and a couple hours later,(in the afternoon, as it was in the sun) it operated normally. It worked as if nothing had happened in the morning.:shrug:
Then it worked yesterday (wasnt too cold) BUT I saw the motor light was on in the dash...
TODAY its -30., and it happened again.
Tried a trick I saw on internet (brake on, going through teh speeds slowly up and down to resinc I think they call it) but it didnt work. Now this afternoon as it is sunny I thought ok, it will work...
NOOOO it wont even start now.:crying: NO click no starting sounds. I turn the switch on and it wont start but radio, heater they work....


HELP me, cant afford an expensive repair( I bet you know if I drivea 2008 car!). Willing to try to do things to fix it as I know mercedes in my area will come up with $$$ bills (they are well known for this!). I am no mechanic but with pictures I cant see why I cant try it.

I heard on youtube of a brake fuse/swithc that might do that???But I dont know where it is.
THen I heard of clutch actuator...at -30 I dont think I can try to do that (and maybe not as first solution)... Could it be just low on oil? (as there is no dipstick I didnt check...was going to try to do transmission oil change on my own this spring...)
PLEase help me, I work part time and am a student I need my car there is no bus system in this town(and I study 30 minutes away from here)so I need it to work asap

oil dipstick yes I know I added oil once a few months back.(does not burn oil) but transmission oil?
there is no voltmeter in dash for battery, but the car always started (ok it was -30 but it still started up to today)

Today the car started as if nothing had happened but it is -9...but the motor light is still on.
The car never started or look like it would start (no starting noise at all)yesterday.(-30)

It has something to do if the car maybe is too cold? I dont have a garage so it does stay outside. Brake works so then I assume it is not that brake relay I heard of?
I was going to check some fuses today...but car started and ran as usual(meaning before the last week problems).

I am now scared to get in the car in the morning, would you say I need to grease lithium that clutch actuator (by moving the rubber I was told(youtube) it can be done. OR even though started always well even at -20 could it be just the battery? but if so would the motor light come on? How can I check if the battery is still good enough? To me my dad (when alive) always used a battery till wouldnt start or charge...so I dont see why the battery would be right now the culprit....
ANY HELP?

Well, the first time this week and yesterday morning it did start the engine it just wouldnt go into moving(gears changed on screen and were not flashing...just as if it would move) then yesterday afternoon when I tried again thats when it wouldnt even start anymore.

But this morning Aok as if nothing ever happened.

Brake switch...if my brake lights work (had my mom check today...but today the car is running!) then it means it works? but it is possible it is intermittent you say...how much is thta and where is it located (can I change it myself? cause if cheap I can try that)
so the actuator then....would temperature affect it... I never did much to the car except oil change and I know I will have to change transmission oil. Now I think the next day that we get above zero I will change it(could it be taht?)

ok so the past 5 days we had near-30 today was the first day I tried the car as it was -20 (yeah still too cold probably). car starts no problem so I would say its not the battery.

tried 1-2 tricks I found on youtube with no luck. car now stays stuck on park with (after I release the brake) then abs light goes on.

I found on internet it might be brake light switch BUT I dont know where it is located and how to remove. The garage in my town that is the only one that is affordable (he is about 25$ per hour) doesnt even want to play with it (he said mercedes smart needs special tools he doesnt have) and the other garage would make me go bankrupt.

So if not too cold. it drives ok, with no light on. And for past 2 weeks where we had mostly -20 to -30 temp. then it developped all these problem.

I dont think the actuator is broken....as like I just said the day it was warmer it shifted no problem and the light disappeared after a few times. But 2 days later it was back to -20ish and then wont even move from park anymore.


First my brake lights are on...can it still be the brake light switch. Second the car started no problem after 5 days not even trying so probably not the battery?

if the car had not move on the warmth day then maybe the actuator might have been broken... but as it drove nicely I guess that is out?

So what this car cant be driven anymore in winter? or theres something to be done?

My mom was kind enough to let me borrow her car...but today I am stuck at home (catn go to school!) because she needed it. Help please willing to try all I can. Links on youtube appreciated...
Tomorrow is warm(-10) so maybe I can try a few things?

(no luck with msamson) they are all $$$ in this area... BTW when it was warm 4 days ago it started ran like a charm, and the codes lights disappeared. But the day after it was -20-30 and would nt get out of park (starts no problem)

to CHRIS: no bars. when it ran 4-5 days ago all was well (but it was like I said warmer) after just park shows now as I cant move the stick anymore.
