The Scanguage I installed on my 2008 Passion now tells me the smart has a "Secondary Air Injection System Malfunction (P0410).  At the same time, the smart's gas mileage fell from 50mpg to 38mpg.

Does anyone have a clue as to what's going on, or a troubleshooting procedure?  The nearest smart center is 400 miles away.

Do you also have a check engine light illuminated? Believe it or not it can be as simple as a loose gas cap, or as extensive as a secondary air (smog) pump.

All the best,

Update:

took the smart to dealer service dept.  They replaced the s"secondary air injection valve" and fixed the stuck shifter in an hour.  I got a replacement valve at their parts counter ($42) so that if if fails again--said to be fairly common--I can replace it without driving 400 miles.  Looks pretty easy, on top of the engine.

They even washed the car.  No charge for anything.  So I had them fill the tires with nitrogen (lots of side extras with this program).  $60.  I'll update when I've had some experience with the nitrogen.

Glad it worked out for you! Thank you for the update. Hopefully this was a 1 time problem.

Update # 2: smart dealership called.  Factory had sent a replacement entire shifter assembly in response to a shifter lockup I had experienced.  I took the smart to the dealership, where they replacedd the shift assembly in an hour and detailed the car.  Nocharge for anything.  I believe the new shifter is an improved version to address the numerous complaints smart owners have lodged re shifter lockups.Louis

Thanks for keeping us informed! Do you know if the dealership had heard the same problem from other smart car owners?

All the best,

the smart service rep was very aware of shifter problems and spoke of a factory service alert sheet.  smart mechanics are having to fly by these service alert sheets in the absence of a smart service manual.  Let's  see . . .you produce a car before you have a service manual for it.

I bought a smart service CD on eBay.  Its shortcoming is much of the content is 450 stuff and its in Btitishese.  You know, bonnets and spanners and blimeys, etc.

Thanks for the heads up! I was thinking about getting one of those CD's on Ebay as well. I will wait for an official manual.

All the best,
