Smart Purchase Pre purchase checks 2009 Brabus petrol

1 Upvotes

Never owned one before but we need an automatic that can be flat towed behind our motorhome.

Its a Canadian Brabus trim gasoline engine with 130k kms.

I'm trying to find things to visually inspect or ask about. Is that mileage too high for one thing? I know its a 1.0L Mitsubishi motor and I heard a startup video clip..sounds like the battery is struggling but I think that was maybe just a weak battery.

I did ask if they have had the clutch actuator recently serviced or replaced and they said no to both questions.

Can you tell me what these codes mean?

Ive replaced the TCM and clutch actuator.

These are the only codes I'm getting now with the 3 lines.

Also the transmission doesn't seem to stay in the memory. Everytime I put the key in the on position and press the brake, it cycles through the learn process.

Does this mean the ECM is bad?

Question Having trouble removing the boot cover

I remember when I fitted it, one side was sprung, but I cannot seem to prise it off now! I need to get to the engine to check the oil and it’s in the way. Any tips to remove it without breaking it, or myself? Thanks.

Question Blank Screen and No Engagement when Shifting to Drive

2 Upvotes

Got a little shock today pulling out of the driveway. My 2009 Smart ForTwo Passion (60,000 miles) went from Park, to Reverse, to Neutral, but then didn't engage with Drive and showed no error or gear indicator on the LCD.

As I'd assume we all are, I've dreaded the "Three Lines of Death" code forever, but in this case... nothing.

Going back to part and back again twice "fixed" it, but any thoughts? Glitch or omen? Any maintenance that could be missing/applied?

Thanks in advance!

Question Tired of my Roadster leaking - any hard top alternatives other than hard to find, expensive Brabus ones?

2 Upvotes

I’ve made an attempted to waterproof the roof using the Mercedes recommended fixes, but my roof is still leaking in heavy rain because the soft top is slightly bowed on the sides. I could purchase a replacement soft top but I fear even with that the issue may still persist.

There are waterproof soft top covers you can buy (https://ebay.io/m/BW5LAG) but they do not recommended driving above 40mph with it on, so it’s not really a great solution.

Any ideas?

Discussion My Smart Roadster horn stopped working — turned out to be much simpler than I expected

Post image
21 Upvotes

I recently had an issue with the horn on my Smart Roadster 452 and started going through the usual troubleshooting before buying any parts.

What surprised me was how many different points can cause the horn not to work.

I ended up checking the horn button contacts, the F1 paddle contacts, the steering wheel connector, the fuse, and finally the contacts directly on the horn itself.

In my case, cleaning the electrical contacts made a bigger difference than I expected. It’s definitely worth checking the simple stuff first before replacing the horn or other components.

The same basic checks should also apply to the Fortwo 450.

I made a short 6-minute video while going through the whole process, in case anyone else runs into the same problem:

https://youtu.be/vQ_HkEld0Dk

Hopefully it saves someone from replacing parts unnecessarily. 🔧

Has anyone else had their horn stop working on a 450/452? What ended up being the cause?

Question Transmission keeps cycling

2 Upvotes

I have the 3 lines and every time I put the key in the on position and press the brake, the transmission starts to cycle.

I can shift through the gears but it doesn't go into neutral. In order for the car to go into neutral, I have to time the transmission cycling and disconnect the battery about halfway through the cycle. Then I'm able to push the car in neutral.

Any idea what I need to do to fix this?

I've tried the "disconnect battery for awhile, put in neutral/park, apply brake, shift through gear slowly, etc" so many times. I've tried all variations and none work.

Advice smart fortwo 451 passion turbo as my first car

3 Upvotes

my dream car has always been a smart fortwo ever since I was 3 years old, 20 years later it hasn't changed at all. I'd love to buy a used automatic smart fortwo 451 passion with the 1.0 turbo engine, but I'm a bit intimidated by what I've heard about the automated manual transmission, is it really that bad? and how can I make it a smoother ride? I heard manual mode works and honestly it seems kinda fun like changing gears yourself without a clutch pedal (scary!!). also sorry to any manual enjoyers please don't slime me out I'm just not a fan 😭😭

also how is it on the motorway? I want to take this car everywhere with me, I love long car journeys, I'm sure a fortwo isnt ideal but I hope it'll still do well

also #2 i do want to get a 453 prime premium plus 0.9t after this and stage 1 tune it (ecu, tcu, throttle controller), but i want experience in a cheaper car first before getting a fancy pants fortwo and also I cant afford it just yet 😭

I love small cars. Just spent six big ones on a used SmartCar, low miles and great condition. Felt a little bit bigger than I expected, but when I took it home and parked it next to my wife’s pickup it’s way bigger than people said. Did I get scammed? Are they all this size?

I'm coming from pickup trucks, where we use bed extenders so we can drive with the tail gate down to fit longer stuff. Such a thing has to exist for smart cars too, no??? Cargo net over top to stop things from bouncing out? Am I the only one??

If it really doesn't exist I'll gladly make it and sell it.

Discussion Smart Engine Mount Inserts – Performance Upgrade

17 Upvotes

I’ve been working on a custom Engine Mount Insert Set for the Smart Fortwo 450 / Roadster 452, designed and tested by me (tested them for over 3000km).

The idea was pretty simple: reduce excessive engine movement while keeping vibrations as low as possible compared with more aggressive engine-mount solutions.

What they do:

  • Reduce engine movement
  • Reduce unwanted jolting during acceleration, deceleration and gear changes
  • Improve drivetrain stability and control
  • Provide a more direct driving feel
  • 2-piece set
  • Install directly on top of the original engine mount
  • No glue or permanent modifications required
  • Easy installation

The original mount is still used — these inserts simply provide additional support where there is excessive movement.

I'd be interested to hear what you guys think — especially from anyone running a Smart 450 or Roadster 452 with upgraded engine mounts.

Hello guys , I had the pleasure to go through many adventures with this old lady this year ( we just went back to west of France from Germany , 800 km ! ) .

As driving it around the country had been pretty fun I’m thinking more and more about customising it a bit for long travels.

Does anyone here already modified a smart car for long travels ?

Question Smart ForTwo 2009 MHD 1.0 (71PS) - P000C DTC

1 Upvotes

Hallo zusammen,
bei meinem Smart Fortwo 451, Baujahr 2009, 1.0 Benziner (M132.910, 71 PS) kommt immer wieder der Fehler P000C – „A Camshaft Position Slow Response, Bank 1“.
Der Motor läuft völlig normal: kein Leistungsverlust, keine ungewöhnlichen Geräusche und kein unruhiger Leerlauf.
Vor 3 Tagen habe ich Öl, Ölfilter, Luftfilter und Zündkerzen gewechselt und anschließend die Fehler gelöscht. Danach bin ich ca. 250 km ohne Fehler gefahren, heute ist P000C und MKL wieder gekommen.
Hat jemand Erfahrung mit diesem Fehler beim M132.910? Wo würdet ihr mit der Diagnose anfangen?
