Hello all, just purchased a 11 SW and looking for some direction on getting this running. Car has 97k on it and had zero maint done to it except oil changes since the prev owner bought at 44k. It was sitting for 9 months in a field prior to me getting it. Owner parked it because it threw a check engine light and lost power (limp mode). I guess local shops couldnt figure it out.


When i got it, with a jump, it started right up and idled fine with no issues. Was in limp mode i believe so it could barely make it up on the dolly.
-Glow plug light was flashing
-Check engine light on
-DPF light on.

Scan with basic scanner revealed
-P2BA6-NOx exceedance - SCR NOx Catalyst Performance
-P0544 Exhaust gas temp circuit bank 1
-P2463 Particulate Filter Restriction
-P12D4 ?

Researching showed me the P0544 seems like a common code, which disables the DPF, then plugging it up. So i jumped the gun and ordered that EGT sensor for that fault. Hoping that sensor was bad and running reruns in hopes to clear out the filter. I decided to clear the codes and scan again, only the NOx exceedance and filter restriction code came back, not the EGT one (i did not replace it).

Bought VCDS and checked all the EGTs, they seem to look good and not out of range, even unplugged them to make sure theyd go bad readings. Current VCDS scan shows the EGT faults, but i believe its from me unplugging them.

Current faults
- NOx Emissions Exceeded
- Excessive Soot Accumulation
-Exhaust Gas Temp Sensor; Bank 1 Sensor 2 P2031
-Sensor 1 for Exhaust Temp Bank 1 (G235) P0544 - 001 - Circuit Malfunction - Intermittent

Any advice on what route to approach next?

Many thanks

Does it have a pano roof? Any signs of water entry? Lots of electric faults in there.

yes it does have the pano, and when I got home it did struggle to open. Also noticed the interior windows were really foggy when sitting in driveway, my other cars in driveway were not.

I will mention again it sat for 9 months and also the battery needs replacement, if that matters.

thanks tor the reply

When I sealed my roof shut(first with clear gorilla tape, then the whole roof with white vinyl), some of my weird intermittent electric problems went away. Check floors for water, esp. the spare wheel compartment. You'll probably see water staining on the headliner as well. It probably doesn't explain the emissions codes, but I bet it has something to do with the other stuff. If you want to have a fully functioning sunroof, then that's your deal, but I think it's more trouble and money than it's worth. If it's fully shut, leave that thing closed. And you probably have some very expensive emissions items to replace or delete(which is also expensive/ labor intense)already.

Most of your DTCs above are from low supply voltage. Get a new H6 starter battery (OE 000915105DG or Costco for $119) and reset all the DTCs. Run the car for a bit then rescan with VCDS and repost the modules with DTCs (fault codes). Let's see if those ECU "circuit malfunctions" DTCs return. --g

Do you have soot in your exhaust pipe? If you wipe it with your finger is it black or just normal road dirt? If sooty chances are very good you have a cracked dpf which has to be replaced or deleted. ID Parts has good prices for the dpf.
The problem with replacing the dpf is the next time it fails…. I would hesitate to throw too many parts at it until you are sure of the dpf status and have a plan.

Reading everything here I think you have a mix of issues.

- The DPF/soot codes are most likely pointing to a bad DPF, the other codes can be thrown with that code, and they make sense if soot is building on the other sensors and NOx converter.
- The moisture on the interior windows is a tell-tale sign of sunroof leaks, whether that is clogged lines or leaking lines.
- You didn't mention fuel filter, I would replace that ASAP and hope no hpfp (high pressure fuel pump) damage has occurred.
- Get a solid battery in it before testing and get at least 2 drive cycles (fully up to temp) on it before reading/clearing the codes again.
- Check really well for wiring issues from mice, they can set up shop really quick and start eating wires, hopefully they stayed away though.

Hey there thanks for reply, no soot in the exhaust. It idled for a hour yesterday getting up to temp and after wiping finger in tailpipe, just looked dirty on the towel, no sooty black.

Thank you for the reply, the fuel filter was the first thing I did, filter look fairly dirty but didn’t see any metal shavings in the canister which is good.

I imagine You’re right with the bad Dpf, I just don’t want to accept it lol. Is there a way to take it off limp mode and force a rerun while driving with vcds in hopes to clear it out a little? Also getting it out of limo would allow me to run a few drive cycles like you mentioned.

battery is next on list. Been keeping the battery charger hooked up to the car while it’s not running

I haven't had to do an emergency regen at all but that is probably what you would want to try doing, you can find the procedure in the forum or on google. I would also suggest if you have a hitch to try pulling a small enclosed trailer at highway speeds, 70mph or more, if you can get up to that doing an emergency regen or manage to get it out of limp mode temporarily. Towing a small trailer at highway speeds will get your EGT's high enough to passively regen, going uphill is even better with a trailer, it can do it as long as it's not in limp mode. That would be your best shot at actually clearing out the DPF if it is able to be saved, doing full throttle redline runs will also help clear out ash from the DPF but wont be enough to regen because of how short that lasts, it doesnt get it hot enough to burn out all the soot.
