Hi guys,

I asked in the X5 forum, but it seems like all the hardcore diesel guys post mostly in this forum.

My wife's 2009 X5 with about 75,000 miles just gave me a CEL warning. The car was and is running just fine, and we haven't noticed a performance or efficiency loss.

Has any one had experience with these two codes? It seems that I am right at the mileage where the carbon build up becomes an issue.

Thanks,

Marco

So I asked my buddy if he could look up the codes in AllData, this is what he came up with.

Looks like the SCR valve is either dead or disconnected.

FAULT CODE: 47F9 - P2063
FAULT TEXT: REDUCING AGENT METERING VALVE, ACTIVATION: NEGATIVE SIDE, SHORT TO EARTH
FAULT DESCRIPTION: THE DDE RECOGNIZES SHORT CIRCUIT TO GROUND ERROR IN THE OUTPUT STAGE:
METERING MODULE.

FAULT CODE: 4C7C - P2064
FAULT TEXT: REDUCING AGENT METERING VALVE, ACTIVATION: POSITIVE SIDE, SHORT TO CIRCUIT TO POSITIVE.
FAULT DESCRIPTION: THE DDE RECOGNIZES SHORT CIRCUIT TO POSITIVE IN THE OUTPUT STAGE:
SCR METERING MODULE.

They'll replace your SCR metering valve.

Perhaps time for a downpipe?

Hi guys,

So I received the SCR valve and decided to look under the X5. To my surprise the valve was very accessible.

Here are the replacement steps:
1) Remove plastic transmission guards
2) Loosen v-band clamp, 4mm allen socket
3) Open up and remove V-band clamp
4) Disconnect DEF fluid feed, press the tabs and pull back
5) Remove electrical connector
6) Clean mounting surface with wire brush
7) Install new DEF Injector, and installation is reverse of removal

Here are some concerns I had, when I removed the DEF feed line, it was dry. I expected some UREA to drain out.

The actual valve did not look bad, but the codes are showing thats internally shorted.

I tried to erase codes but I couldn't do it. Anyone else have this experience?

[nobrakese28]

I will probably need to drive the car a bit to see if the code clears.

Has anyone replaced the SCR Metering Valve/DEF Injector?

Has anyone replaced the supply module (UREA pump)?

Has anyone replaced the transfer pump (passive to active tank)?

Thanks,

Marco

The DEF feed line purges back into the tank after every shutdown, so I would expect it to be dry. The reason it purges, the engineers were concerned about DEF freezing in the lines. So DEF is pumped back into the tank after every shutdown. Then upon next startup, when the car and the DEF in the active tank has been heated up to prescribed temps, then the car will begin injecting DEF.

So that is why we hear those noises back there after shutdown of the engine.

Hey guys, thanks for that info, that is great to know.

The CEL has cleared, I am a happy guy. The on system computer was right.

Just had the same issue with my 335d @ 125,000 km which is roughly 70,000 miles. Was getting codes P2062, P2063 P208E. Bought a new DEF injection valve from RM European http://www.rmeuropean.com/Products/1...206-MFG14.aspx which was the lowest price I could find (I live in Canada and had a buddy coming up from the USA who brought it up for me which saved a lot of $). Replacing the part is very easy - pretty well as described above. I measured the resistance between the contacts on the old one . . . infinite . . . indicating a wire had broken and the new one ~ 46 ohms. The longest part of the job was getting the v-band clamp back on. On start-up code 2063 was no longer there but codes P2062 and P208E are still there. Any ideas?

I believe after you clear code, the next cycle of start/run will register correct operating parameters and you should be good to go.

Does anyone have pictures of how to replace the broken part?

[Stevemeister]

Thanks - it did exactly that
