It seems that this forum is the default go to forum for just about anything and everything, including topics best kept elsewhere, since we have a forum for most every topic.... But alas, place it here I guess - it's not likely to get kicked out... LOL!
This forum is for discussion about the production and distribution of smart cars. If you want to know the quantity of vehicles in each province or country, visit here! We maintain lists of special edition smarts, often with the VIN # when possible. This is also the place to visit if you need help with tracking your smartie. It could be in the factory, on a ship, on a train -- or at your dealership!

I was lucky enough to get a hold of #44
Maybe I'm not looking in the right spot but information on these is not as prevalent as I thought it would be. Correct me if I'm wrong but this is just an aesthetic package right? The engine is still a 40 horsepower 74 foot pound diesel engine.
There is no pressure sensor on intercooler. That sensor is for inlet air temperature.
On our CP1 high pressure pump the pumping element that can be disabled as fitted with a cut off solenoid. As I recall, pump element is enabled when solenoid is not energised. Solenoid simply operates a pin that keeps inlet valve in open position when solenoid is energised. The purpose of the cut off solenoid is solely to allow the pump to operate only two pumping elements, resulting in less engine power being consumed at low engine loads.
Disconnecting connector would therefore make all three pumping elements operate at all times.
I could of course be wrong so need to check this tomorrow morning.
Solenoid is seen on right hand side of above photo.
Solenoid pin is just visible in above photo.
PS. Good news you got yours sorted.
Ok, time to install the pump. Been working on fitting it in for about 2 hours. How do you line up the tabs? I tried putting the piece with two tabs onto the crank first and onto the pump. No luck either way. Frustration rising....
So I finally broke down and decided to have the turbo looked at in my 450 by and independent garage.
A short recap. Last summer, from one day to another I lost boost in the car. The question was always, was it a lack of boost or Limp Home mode?
The car didn't throw a code or CEL so I started digging.
1. the hose from the EGR to the turbo - It happened to me before when I repaired the intercooler so I reinstall the pipe. - no change
2. EGR is stuck - I remove and check it. I had put a blocker plate last year - Nope slides perfectly
3. intake pressure sensor mounted near the dipstick - Nope
4. intake pressure sensor mounted on the intercooler - Nope in tight.
5. limp home mode. - disconnect the battery for 10 minutes - Still no power
6. leaky waste gate pressure hose (the short one that goes from the turbo high side barb to the actuator head) - Looks good
7. Struck waste gate - Lubed and loosen but seemed OK. I lengthened the arm to see if it was not sitting well - Nope
8, Bad Intercooler - I changed out the Intercooler with a used one but in good condition and pressure tested.
9. Bad turbo - I removed the intake and it looked clean with no broken fins or free play
10. Pressure test with a rubber clip and a plastic plumbing fitting that I connected a fitting to connect to my compressor. Block off the Intake to the motor with a plastic sheet and see if it holds boost. - No leaks.
Finally I brought it to a independent garage I found who deals almost exclusively in Smarts. He found the problem in no time with a more elaborate code reader. His code reader showed a problem with the high pressure pump.
** It was the connector to the high pressure fuel pump. **
Somehow the connector was inserted but not clipped in to the end. When he pulled it came off in his hand! He plugged it back in and the car ran like it was new.
$60 and it was fixed! After all of the hours I spent trying to figure it out.
I highly recommend this garage if you're in the Montreal area and need service for your car. If, like me, you cannot stand bringing your car to the Stealership where you get robbed blind.

He is very knowledgeable and showed me exactly the issue without a big production.
I love my 450 and people ask me often if they should consider one. I always have to say that they are great if you know how to fix them because I have never found a garage that knew anything about them.
Also, as some may recall my experience with the dealer borders on litigation.
I can now recommend the car with the knowledge that someone can have it serviced at a reasonable price by competent mechanic.
