So I have a 2010 R56 S and have the limp home issues. Right now its on jacks for the oil cooler leaking ( whole 'nother issue ) but along with this there are a number of codes that I have been pulling from the car when it seems to be above 3K RPM and in a boosted condition. I've done some checking online and not quite sure where to head with it as it seems by what I'm seeing it looks to kinda be all over the place.

Here's a link to the Google Sheets spreadsheet that I have started creating to keep track of what Im reading and what the decoder ( being that I'm using INPA to read it because the regular generic code readers will not show anything )

Google Sheets List

It would "appear" that there's an issue with the Footwell Module ( shocking possibility ) battery, and the one that I think is throwing the car into limp mode would be ( 12DME/DDE288562DME: Charge-air pressure control deviation, plausibility ) but not sure where to start looking into that one.

Any thoughts on it would be greatly appreciated as I'd really like to get this off jacks, out of my garage and back onto the market for someone else to enjoy but want to make sure that its not a basket case when sold.

And what it looked like the other day:



Thanks!

 

Most of these codes are related to the battery. if the battery in good condition, clear codes and see what comes back. make sure everything is connected for accuracy.

 

Cleared 3x and still codes for days.

Might just have to replace it ( battery ) at this point. It's been completely discharged multiple times due to sitting and think its about time on it anyhow.

 

yeah, start with the battery for now and see what else comes back.

was the limp mode because of this or the oil cooler?

 

The oil cooler was just making one heck of a mess and needed to be cleaned up and taken care of. I'd say that its unrelated. Not quite sure what the limp mode was but I have a feeling that it may be DME: Charge-air pressure control deviation, plausibility related.

 

If your code "12DME/DDE288562DME: Charge-air pressure control deviation, plausibility " is related to the P2885 code, you most likely have a turbo related problem --- waste gate, DV, blocked cat, etc.

 

This does not sound like its going to be "wallet friendly."

Thanks

 

this codes sometimes appear with vacuum leaks, sometimes misfire...sort out the easy ones then move the major ones. dont assume anything just yet!

 

Good call.
