Cooper, 2009, Seafoamed for second time at 31K miles. Got lots of smoke (almost a half hour worth) and the "yellow check engine" light (that did not happen the first time. Smoke, but no light). Scan guage says "2 codes", but one is blank and the second is P0000. Tried to clear it and only get blank screen (manual says engine not responding). I do not see a P0000 code in Nathan's chart. What is going on here ??????? Jim
Half an hours worth of smoke, wow, bet your neighbors were impressed. Jim, didn't you just do this recently? It's POOOO, your engine is saying the s ward. Where did you add the sea-foam in your engine? And did you add a lot?
It was done about two months ago. I read that you should do it again as the first time normally did not do a lot and you would get more smoke the second time which I did. I let it sit awhile then took it for a drive. Runs fine, idle is smoother, but I still have the light and some smoke. I put it in through the PCV line, just like last time. I used just over half a can. I did NOT put any in the gas after what happened last time. Jim
I found this over at the you know where site. MINI COOPER :: North American Motoring - Vacuum Leak? Sounds kind of like what you have going on about the second code being thrown but can't read it? The SGII is somewhat limited in what it can report. DrO sells a very good one, but that won't help you now. You might consider going to AutoZone and see if they will put their reader on your car?
I've got the S which has two PCV circuits, one goes through the IC (don't want to use this one because several sensors will get fowled up) the second goes directly to the intake manifold (that's the one to use). You have a Cooper if I remember, so I'm not sure where you PCV hose leads to. If any of your sensors have been fowled??
Thanks buddy. Something else odd happened. I did not touch the battery or reset anything, but the clock changed from 24 to 12 hour rimwe on its own. Jim
After reading the thread you found for me (thank you) I opened the hood and checked the PCV connection (The Cooper has only one hose). It seemed tight, but I fiddled with it anyway. Styarted tha car and everything was back to normal. No light, smooth idle, good responce. The Scan Guage still says two codes, but all is well again. :confused5: Jim
I don't think I want to know. Haunted perhaps. The Cooper (non "S") DOES have direct injection doesn't it? Jim
After a certain amount of start cycles the lights will likely go out. If I start, from cold, my 03 justa, and turn it off right away, then restart, I sometimes get a light, and a 02 sensor code. I just start it normally 4-6 times, and the light clears. It may be time for a new 02 sensor though. Mark
Thanks Mark, but I have a 2009. I surely hope the o2 sensor is not going. I did actually re-start her about 5 times when the light went out. Perhaps there were some Irish workers in the plant when she was built and there is one of the little people lerking under the bonnet. Hummm, need to go see if there is a pot of gold in there some place. Jim
I could be wrong, but I think both generations take a certain amount of start cycles to clear certain codes. Mark
Jim, I wouldn't worry about the O2 sensor. Your 09 would still be under warranty and the O2 sensor is part of your emission system. I'm also thinking that the emission system has a longer warranty as a federal requirement.
Justa is NOT DI... it's conventional port injection. And there are codes and there are codes. Some clear by themselves after a certain number of "drive cycels" (a drive cycle is usually defined as going from cold start to fully warmed engine) without the fault being found, some latch and stay till cleared. The only ones to really, really worry about are the ones where the check engine light flashes. Those are the ones where the electrical mother in law thinks that further driving will damage something... Matt
Are you trying to clear the codes with the engine off or on? Some codes only clear with the engine off -- insert key press the start button without touching the clutch -- then try and clear the code.
There is only one hose regulated by the PCV and it is the one with the small rubber hose and grey pipe connected to the manifold. The other is just fresh filtered air and is not under constant vacuum from the manifold because it is in front of the throttle. I have also seen code readers like scan gauge unable to to read codes properly. R56 software is just too new and there are too many vehicle specific trouble codes for older scanners to recognize. I have a really good Mac tools hand held scanner but the software is too old to deal with R56 scanning. You need to read all codes Key On Engine off. The only way you scan with Engine on is if your scanner can do live data
Cal330ci......... Thanks for clarifying the pcv circuit. Are there effective methods to prevent carbon buildup on the back side of the valves on the DI engine short of a head removal and manually removing the buildup?
If the Cooper is not DI, then do I need to use Seafoam at all?? Thanks for the info about the codes. Jim
