I have a Smart 450 2007 with 20000k on the clock, I have had it stored for a couple of years and went to it a couple of weeks ago, connected the battery and it started first time. I noticed it was a bit smokey so I purchased the fuel treatment and all was good until now, It has now lost power and its creating smoke even at slow revs, I have removed and cleaned the EGR valve and its now sparkling once reassembled it still smokes... any thoughts would be useful.. thanks in advance

The Dorkmobile is at it again. When the boy drives it he says it gives a little bump then loses power and had a hard time maintaining 85 Km/h. Rarely gives a CEL. When it finally did, it came up with P2038. (Reductant injection air pressure sensor- range/performance problem) Everything I can look up referred to a DEF injector, which we all know it does not have. I had parts on hand so I replaced the Fuel Pressure sensor and the MAP sensor. Still same issue. The only thing I can think of, is it may need a new muffler. There is an exhaust leak at the bottom seam and a significant amount is escaping out not far from the exhaust nozzle. I went to a custom exhaust shop and he said he can fab a system with just a resonator for less than half the price of an OEM muffler but he had an 03 and never had that issue when his exhaust was leaking. I am at a loss. No idea where to go from here. Ideas?

Last year driving my 2008 I all of a sudden had no power, couldn’t get above 10 miles an hour. Unfortunately I had to let it sit because of funds. When I went to move it recently it wouldn’t move at all so I went drive then reverse and after a few tries it “broke” free. Now it sounds like the brakes are locked and it scratches metal on metal while driving. Went up my hill and it kinda sputters with the power now. I did notice a very small puddle of some oil on my passenger side front rim. Is my axel shot? Could that have been my problem last year with loss of power? Thanks in advance everyone!

I've been having a lot of problems with my '06 450 CDI Passion. The battery light keeps coming on after the engine has been idling for about 10 seconds, and never goes off again. I took it for servicing, and was told that the aftermarket stereo & amp were causing a drain - not true, because I've removed both from the car. Here are some more details: I'm on my THIRD alternator in 3 years (replaced 1 year ago, car has only been driveable for 3 months since!!) so I doubt it's the alternator Brand new Smart battery installed 3 weeks ago, driven once since (back from mechanic, battery light came on about 15 min into my trip home) The only issue I can see with the battery is that the bolt for the bracket that holds it down has been sheared off (see red box in photo), so the battery slides around a fair bit, and the bolt hole is very rusty (I wire brushed it). Also, the ground connection to the frame is rusty as well (see green box in photo), and I cannot remove the washer, so I'm not convinced that the ground has proper contact with the frame. No error codes Used multimeter, battery puts out about 13V (I think? I don't know much about electrical stuff) Last week when testing the battery with the multimeter, I turned the car off. Then tried to start again, and got the immobilizer key on dash. Pulled key, locked/unlocked doors, tried to start, got the immobilizer again. Repeat x3 before giving up. 2 days ago, I brought my portable power pack and jump-started the Smart, started fine, no battery light. Let it idle for 5 minutes before unhooking the jump cables. Battery light came on within 10 seconds of removing the jump cables. I can't find a parasitic draw anywhere (doesn't mean there isn't one, just that I can't find anything) All fuses good I've also been having an issue for over 2years with a drastic loss of power when on the highway. The car won't go more than 90km/hr, even in 6th gear. I used to keep it in 5th for maximum torque. Replaced turbo TWICE, did EGR valves, replaced clutch, transmission ok, and no error codes. Please help me figure this out! I've spent over $3,000 fixing this car in the past 1.5 years alone, and I'm not putting any more money into guesswork. If I can't figure this out, I have to get rid of the car. I'd like to keep it, but I'm out of ideas on what to check or do to figure out what's going on. **Photo from Evilution
