Smart Car Soft Top System Adjustment | W451 | DIY Guide 

Yes, it is possible to adjust the roof on your W451 Cabrio to bring it tighter on the side where you are experiencing wind noise. The adjustment will depend on the specific issue causing the uneven closure of the roof. First, you should check if there is any debris or obstruction preventing the roof from closing evenly. If this is the case, remove the debris or obstruction and try closing the roof again to see if the problem has been resolved. If there is no debris or obstruction, the issue may be with the roof latch. Check if the latch is securely fastened and tightened. If it is loose, tighten it using the appropriate tools. If the issue persists, you may need to adjust the tension on the roof cables. This can be done by loosening the cables and then tightening them to ensure equal tension on both sides. If you are not comfortable performing these adjustments yourself, it is recommended that you take your vehicle to a qualified mechanic or dealership to have the roof inspected and repaired. They will have the expertise and tools to properly diagnose and fix the issue.

Did you manage to fix it?

@@byPulsey much better, put a thin washer behind the latch on the front screen, the hook on the roof wasn’t quite reaching, then sprayed silicone on the side slide runners and front latch and kept working them over a 2 week period. Much better now 👍

I really want to know this aswell. Or another link for 450 🙏🏻

@@leolundgren2054 More than 5 years ago Mate 😅👍🏻

​@@rikybologna3579Yepp but I know many 450-cabrio owners has, are or will struggling with their cabrio. I have the problem now man. Dis you find any guide for 450 during these 5 years? 🙏🏻

It's possible, but it will be much cost to pay. Better sell the coupe one and buy cabrio then

Did you find them? They are just spacers. I imagine you can just cut a small section out of washers the correct thickness if you cannot get the part. Not ideal I know but I may have to try and adjust my soft top myself because it doesn't close properly. I can't afford a pro to do it.

@@DivergentDroid thank you for the reply but this was over a yr ago. That car has long been sold. Thanks again.

@@socomsfinest1184 Ah.. I was hoping you knew where to get the correct part. I just bought my Smart Fortwo, I plan to keep it till the day I die.

@@DivergentDroid yes! That was actually my 3rd smart. In total I have owned 4. And I do plan on buying more. Just not the convertible any more. To many problems and not enough techs or no people here where I live to fix it.

@@DivergentDroid 🤣😂

keith phillips - having the same issue with the "2nd stage" not dropping all the way. Did you get the problem fixed?
