  1. Hey everyone, I picked up another smart the other day! It's a 2005 passion and was only $250! I plan on using it for parts but I'm curious to fix it as well haha. The previous owner said it died on him a few times and was lacking power so he wanted to part ways with it. I drove it home 40km and it ran/shifted well but noticed it lacked any power in 5th and 6th gear with 90kph being all it had with the foot to the floor. It revs over 3000rpm so it isn't limp. I scanned for codes and there were none. I repaired the sam cracked solder joints, fixed the intercooler, deleted the egr, lubed/tested the wastegate, checked hoses for obvious boost leaks, inspected the turbo and checked for play. The turbo spools nicely and doesn't make any abnormal noises. The cars only making 2-3psi of boost at this time. Anyone have some insight on what could be causing the low boost pressure? Thank you.
  2. Its been some time but its been worth it. I've been able to achieve stable boosts above 20psi on the 2005 and 2006 CDI. Both cars do not have any after market items, except the 2006 with a 2" lift kit and larger tires. The tune I've been working on changes the boost pressure sensor voltage and that allows us to pass the 18.1psi limit. The turbo has been pushed and registered 22.6psi, how accurate that is on a digital reading? Time to install a boost gauge. The rest of the tune has produced considerable gains in all rages and currently verifying fuel mileage. Next step is adjusting the shift patterns and times. Looking forward to comments and anyone else with know issues I should consider or keep an eye out for.
  3. Hello all, my 2005 CDI is having issues in 6th gear. Monitoring boost in gears 1-5 seem to be normal. When I shift in to 6th gear the car will make around 4lb of boost at roughly 2,000rpm and I eventually have to shift back into 5th to maintain speed. I plugged my Delphi scanner in and there is no codes. I had pulled and inspected the inter-cooler along with all pressure piping. The wastegate tension is tight and lubed up, EGR is clean, Clutch actuator has been inspected and lubricated.Has anyone seen this in the past, is the other parameters that i should be monitoring? TIA
  4. Hey Folks, 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. The owner is Norman Comeau 200 BOUL LAURIER, McMasterville, QC J3G 1P8 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.
