Hey guys,
I have a 2007 Mini cooper r56 and she doesn't seem to be starting, I scanned for codes, and pulled a P15E8, I have searched everywhere but can't find what this means, I replaced the battery but still all she does is crank. I replaced the radiator recently but I don't think the problem is related to that, I mean the car would still start right? I have no idea what the problem is, any help or tips are appreciated. Thank you

 

Do you hear the fuel pump??

I'm referring to the one in the tank under the rear seat..no fuel, no vroom.

Oh and
P15E8 - Engine shutdown time, plausibility: Time too short relative to temperature drop in engine coolant

 

I took pressure off the fuel system and put it back into on and the fuel rail is recharged every time, so I don't think its fuel.

 

can you spray "quick start" after the air box and see if the car starts?

 

I second that. Remember to read the instructions - more is not always better

 

I already tried quick start still no luck.

 

If you've used starting fluid through the MAF sensor chances are that it is ruined.

If there is a bubble in the cooling system at the temp sender or the temp sender is not reading properly it may very well keep the car from starting.

 

Did you try it after the intercooler right when it elbows to throttle body?

 

P15E8 relates to coolant --- you recently replaced the radiator --- try resetting the code, check and fill coolant to proper level with 50 - 50 mix as recommended in owners manual. You may have had a large air pocket that circulated to the temp sensor. Code is "Engine shutdown time, ---" it's possible that the ECU has actually shut it down, waiting for you to fix a coolant problem and reset the ECU.

 

I cleared the codes, but it still won't start, oh and do you know how to get rid of the large air pocket I may have created?

 

For all of the engine swaps i did, i never had issues with coolant being less or not enough. I think there is something else.
Can you check for spark?
Also, how did all that happen?
Did you check for compression?
Do you have N14 engine or N12, did you have timing chain rattle issues, or replaced...etc

 

I'm pretty sure it has spark and p15e8 was the only code I pulled, I have an N12 engine, I've never had any timing issues, only a valve cover gasket that needed to be replaced.

 

And you checked all fuese and all plugs? How far are you from philly PA?

 

I haven't checked all fuses yet, but I just flushed the cooling system and and cleared the codes again, and now all it does is choke it doesn't crank anymore, haha, and I live in California.

 

Oh..you're far...i would loved to stop by and look look into it. The car is automatic or manual? Take the plugs out for and take a look if they are wet. Also shine some light into the cylinder and see if they are flooded. Charge the battery for now.

 

It's an automatic, and okay will do. Thank you for your help.

 

Also check just for the heck of it of the cables to the ECU are connected right. Also check the ground connection on the passenger side right next to the motor mount

 

The ground connection for the spark plug boots?

 

I meant the ground strap. But you can check this too. The car wont start after you finished the radiator replacement job, right?

 

I don't know where the ground strap is, but yeah after I replaced the radiator, it turned on so I let the car sit for a while but after going back to it, it didn't turn on, Update, yesterday the lights and everything were flickering, and the radio was on and off and some windows were moving by themselves, I'm starting to think it's an electrical problem, maybe an alternator

 

I found the ground and it looks okay, there's no fraying or anything

 

The flickering is because the battery dying. Try to get another obd reading even though no check light!

 

The check engine is on, but when I plug in the scanner the light on the scanner flickers so much and is so faint you can't read it.

 

any updates my friend?

 

hey, sorry for the wait, but no still the same problem, a put in a new battery and that is drained to, i'm starting to think it's for sure an alternator
