Moin, I drive a Smart451 (BJ2012 with only 25TKM), which I took over 4 years ago from 1st hand, basically little driving (about 3-5TKM per year) and was maintained by a Mercedes workshop every year checkbook. I don’t plan to leave the car anymore and remember that this year a “big inspection” is due. Now I wonder if checkbook in a Mercedes workshop, which is quite expensive, is still worth it? I have acquaintances, who know each other well with cars and would “repair” the smart for a fair deal, I just have to tell them what to do. What is your opinion about it? If you let friends do what I know (there is a catalog on the Internet)? Greeting, Constantin

Hello. The climate has not been running for a few years and now I have filled the climate myself with …. 300g climate gas 50ml climate oil 10ml sealant. The compressor runs and the system cools as well. Unfortunately, I am dissatisfied with the cooling performance. She also noticed that the cooling at high engine speeds cools better, but that doesn’t make any sense. After the last ride it also dripped the underbody and it was no climatic gas, probably more water. Is that normal?

Since today’s 28.11.2021 the little one stretches out, since I don’t really understand what of vehicles I would like to draw on your knowledge. The electronics of the vehicle started spinning during the ride, turn signal did not go, ABS light jumped short to radio went off, fans stopped turning, engine lost power went but then again. Did it go up to a parking lot. Engine: off -> yes, on -> no. Turn the key in the ignition lock, there is no effort of the starter or the same. The electronics stricken: – Headlights (if at) falckern – Fans run at all or turn down – Gang indicator changes short to 3 strokes – Locking of the vehicle not possible After a short pause “stricts” the control device and the closing of the vehicle is possible again. Bordbaterie is vital and well charged, terminals on the battery are well attached and have contact. All fuses in the installed condition checked and passed. Can anyone help me, do you have an idea?

Currently I use Mobil 1 FS 0W-40 with LM Molygen MP and MoS2 for the control chain. Would you like to use my oil supply (15L) to switch to something else, because the molygen is quite overpriced. Should there be something with solid lubricant again, because I have a control chain in Smart 451! Would the Ceramo Ester from MANNOL be recommended? You get much cheaper than the additives from LM. In addition, I would like to add some ester and in the summer the MANNOL Motor Doctor (VI-improver) My Smart 451 Turbo has a Sport-LK and has been chipped, is now about 130hp. The Mobil 1 FS 0W-40 is certainly one of the best 0W-40 oils anyway? If the Mobil 1 FS X2 5W-50 is cheap on Primeday, I would probably take that for the summer. But unfortunately, most dealers only have the X1. In winter I don’t like to drive 5W oil!

Hello, I have the following problems on my Smart 451 since this afternoon. – If I turn on the ignition the radio does not automatically turn on (until this morning always functioned perfectly), but it can be switched on manually after the engine start – the air button no longer works – and finally the seat heating also strikes (if you keep the push button of the seat heating lit a lamp, but does not stay on) as said …. this morning everything was still OK …. and all of a sudden these three mistakes!! about helpful answers and tips I would be very grateful!!!

Hello, I have a “comish” sound when starting the first one after a long standstill. It sounds like a wheel bearing or drive joint is broken…so a duck duck duck…and then it’s already gone and doesn’t appear any more when driving on. Is there something broken or is there possibly something in/after. Hope the little one doesn’t develop into a patient already in the first year ;/ Greetings Thomas

Hello people I have a problem with my smart and that is that a smart year 2000 with 54 hp is the problem when I press the remote control to open the flashers 5-6 times that can not be opened and close I had to work over the small suitcase room me in the anteroom and open with the hand door and start it also can not be displayed in the display a x now I wanted to ask what it can be when I lay down at the bottom left in driver’s room then where the relays are clicks it also six times or five times unfortunately I don’t know about the matter and would be happy about some tips how I can fix this I already thank you for your wheel stand with kind regards Basti

Hello dear SMARTis So first of all to my smart: Fortwo, 60PS petrol – Passion BJ 07/2004 70000 km/h Checkbook maintained if anything is important please ask, am the total car noob , especially I have the smart only 1 week The problem: Suddenly on the highway after which I already kicked it arg ( almost to the red area of the rev indicator ) happens suddenly the following: Engine light goes on and power loss of the engine. Error read out: Diagnosis: Ignition problems sporadically Cylinder 2 Reperature: Ignition plugs change, compression impeccable, car runs again 1a ! ABER: The Autowerkstadt ( not a smart partner ) my spark plug looks questionable, another borderline – both from cylinder 2… and the spark plugs were even wilted 5000km ago, he would have seen something like this already with a smart engine which was then full in the ass! Here is a photo of the spark plugs : Is each the “good”, the “thinkable” and a “normal spark plug” would somehow be used for me.

Hello, with the Smart (Smart smart fortwo coupe pure micro hybrid drive, 999 cc / 61 hp) which I want to buy, the yellow engine control lights up and starts to flash after a certain time. The dealer says that head gasket is defective. White smoke or stinking exhaust gases are not available. Also no cooling water drops in the oil. Oil is very good. Also no smell in the cooling water. Further there is the uncertainty whether the cylinder treads have a damage. Since I want to buy the Smart first, I can of course not say anything what happened with the car before. I am a trained engine builder and would like to direct the Smart. Would be nice if the repair went WITHOUT engine expansion. First and most important question: is the head gasket change possible WITHOUT engine expansion? Thank you!

Yesterday, when I drove my girlfriend to work around 1 p.m., the car was still running quite normal. But on the way back, I noticed something strange: the brightness of the radio changed by itself between bright and dark lighting, in a rhythm that I usually only know, because when I turn off the headlights or the brightness of the radio adapts. At home, I first turned off the car in front of the front door and wanted to leave again later. But when I returned after about 1.5 hours, the car didn’t jump any more. A look at the dashboard showed me that the left turn signal flashed by itself, although I hadn’t activated it. I then looked at various forum entries and videos regarding the problem that the smart didn’t start. There, among other things, possible causes such as starter, alternator, cable breakage or cable shoe were discussed. However, these explanations did not take into account the additional problem of crazy electronics.https://youtu.be/Vr6ZJWDXi-8 Petrolter 698 cm3 37kW BJ 05/2003
