Engine Drivetrain 2nd Gen Most liked posts in thread: Seafoam = Check Engine = Will Not Clear

This is incredible advice after days of trying various things. I now have new plugs and have switched coils (to no avail, lol), and NO CEL! Thank you! This worked!

 

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?

 

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??

 

Sounds more electrical related than anything you did with the seafoam.

 

Glad it worked out. Not sure how your problem might have changed your clock???

 

Don't argue!

MM the miracle worker strike again!

 

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.

I could be wrong, but I think both generations take a certain amount of start cycles to clear certain codes.

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...

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

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?
