  1. Sorry, I don't have a picture that would help. Above your knees on the driver's side is a cardboard fiber shield which must be removed to expose the SAM. The wiring harness connectors plug into the top of the now exposed SAM. There is space between all the wires in the harness and the top surface of the SAM. It is a simple matter to insert a kitchen sponge between the wiring harness and the top of the SAM. The Sam does not have to be removed.
  2. EDiT: Just another thought. After buying the car I noticed that the driver's door handle had a great deal of vertical scoring on it as though the car had slid along the road on its left side, Where would the oil from the intercooler go if the car were tipped on its left hand side?
  3. Not even if parked nose up on a steep hill? This would mean that the crancase oil was pushed to the rear of the crankcase. I am not familiar with how the inlet hose is routed or what path oil from the intercooler would take when parked nose up on a hill. When I bought the car used in 2007 everything seemed fine until about a week later when I noticed oil ooziing out of the air intake on the left side. At the time there were a number of threads on the forum about overfilling the crankcase and when I checked the oil level it was way above the dipstick line. Removing about 1 litre resolved the problem.
  4. In a previous thread you stated "Oil on mine is separated out and ducted back to sump whilst air still containing some oil enters air inlet duct just before turbo." My question then is if the 450 breather enters the intake just before the turbo, how much oil would be deposited into the inlet pipe if the car were significantly overfilled?
  5. I doubt it. It wasn't oil staining, it was oil oozing.The car was extremely overfilled with oil. I don't know where the PCV valve output enters the air stream, but when parked on a hill nose up can't oil from the intercooler flow into the air intake? According to Tolsen "air still containing some oil enters air inlet duct just before turbo" Breather pipe repair https://www.evilution.co.uk/Engine/top_breather_pipe_repair.htm
  6. When I bought my used 2005 Cabriolet in 2007 I would park it on my driveway pointing uphill. A few days later I noticed oil oozing out of the air intake on the left hand side. Checking the oil level revealed that it had been significantly overfilled. I removed at least 1 liter to go below the fill line on the dipstick. My reason for telling the story is to ask if your car has been ovefilled and oil is veing vented into the intake from the PCV valve?
  7. Shortly after I had bought my used 2005 Cabriolet I noticed oil oozing out of the air intake on the left hand side of the car. I removed about a litre to fix the problem. My car is parked nose up on a hill on my driveway. I don't know whether this compounded the problem or not. Some on this forum have discounted my observations, but I think it is generally agreed that overfilling is not a good thing.
  8. After major water incursion into my SAM which I attributed more to cold weather (air conditioning ?) condensation collecting on the SAM wiring harness and wicking into the SAM connectors, I placed a sponge between the wiring harness and the SAM at the top of the SAM. Six years later of continuous outdoor parking and no further issues.
  9. My battery went dead after not driving my 2005 Cabriolet for a while. I charged it in above freezing temperatures and left it on a low current (<2 A) for a day after it was fully charged. During this time, the temperature dropped precipitously and when I got home I noticed a large amount of frost on the INSIDE passenger (right) window and the INSIDE of the windshield but not on the driver's side Because of the distribution of the frost it appeared to me that the battery was venting while charging. This was an ominous sign because 5 years previously I had major water incursion into my SAM after a similar dead battery occurrence. Because while overcharging the vented moisture also contained sulfuric acid, multiple traces and even one of the legs on an IC chip in the SAM were eaten away. It has been my belief that water incursion into the SAM occurs not by windshield leakage, but by condensation on the wiring harness above the SAM from air conditioning or low temperatures and which wicks into the connectors. As a preventative measure 5 years ago I placed a sponge in between the wiring harness and the top of the SAM to mitigate any future water damage. The battery is supposed to have a vent hose to steer such venting to the outside. It is likely that mine is not connected. Just a heads up for any who need to charge their battery and as a preventative measure I would recommend placing a sponge between the wiring harness and the top of the SAM.
  10. Thanks for the link. I recently found a new hobby. Buying and fixing used electric mobility scooters which frequently may be purchased for not much more than $100. The most common fault is dead batteries and the meter that you suggested appears to be a very useful tool in determining battery health.
  11. Perhaps my language wasn't technically perfect. 6 years ago when the first incident occurred, opening the car door while the car battery was charging revealed a very strong odour which was enough to irritate the eyes and could be tasted. Although you are correct in stating that hydrogen and oxygen are produced when venting, apparently a sulfuruc acid mist can also occur and hydrogen sulfide gas (H2S) can also be produced. H2S when combined with water will form a weak acid.
  12. My experience with a badly water damaged SAM is that condensation in cold weather or airconditioning accumulates on the wire harness and wicks into the SAM connectors causing corrosion which leads to increased connector resistances resulting in heating and other issues. My situation was compounded by having a weak improperly vented 12V battery which I frequently charged with an external 12V supply which resulted in sulfuric acid fumes being released into the car. Over a period of time this completely ate away at a number of metaliic pins on one of the IC chips in the SAM. After repairig my SAM 6 years ago I inserted a sponge on the upper side of the SAM between the wiring harness and the SAM. Parked outside in extremely bad Toronto weather for the past 6 years, no further problems. Many seem to feel that a leaking windshield causes these issues. I don't. http://clubsmartcar.com/index.php?/topic/27439-some-information-which-may-help-others-repair-water-damage-on-their-sam-circuit-board/#comment-316230
  13. Is your wastegate stuck?
  14. I don't know whether this related, but on the SAM are 9 connectors, 5 always on, 4 switched. If the ignition circuit has been plugged into the always on connector this may be the issue.
  15. Isn't this why the stability control light comes on?
  16. Do you mean that the tach isn't reading as high as it should be or the engine isn't revving as high as it should be? With your car standing still in neutral and putting your foot on the accelerator what is the maximum RPM that can be reached? If it is only about 3,000 RPM then the most likely explanation is that the car is in limp mode resulting usually from a stuck EGR valve or wastegate.
  17. Although I took material science at university, I must have been away the day that the von Mises and Tresca yield criterion was taught. I had to look it up.
  18. I have two 2005 cabriolets. Over the years on 2 occasions I have found metal rings on my driveway, both virtually identical. They are from a broken front spring, one on each car. The photo below is from another thread which comments that there is a flaw on the springs which creates a weakened point at the same place on every spring.
  19. See if this fixes the problem. http://clubsmartcar.com/index.php?/topic/30904-weird-issue/
  20. Although I haven't used it on my smart, I have used it on other tires and it works! I am referring to the liquid tire sealant in the plastic container that is stored in the foam footpad under the passenger seat carpet. Remove the tire valve, inject the liquid into the tire, replace the valve, pump up the tire, drive the car to spread it around.
  21. How are your tire pressures?
  22. My 2005 Cabriolet had a water leak on the front passenger side. When I took it through a car wash, water could be see dripping from the pillar. Later after rolling the roof back I noticed a significant amount of dirt and debris in the rubber flashing which seals the top at the front. Cleaning it out fixed the problem which I proved with another car wash check.
  23. It is my understanding that it is possible to add a knob with a pushbutton and I believe also a software change to enable "Tiptronic?" shifting.
  24. 75,000 km on my 2005 smart. After unseizing my alternator, a few weeks later I also experienced the no charge indicator light on my dash. I'm not a happy camper and am curious what type of fault (from corrosion?) occurred a few weeks after the alternator was unseized.
