N54 Fault Code CDA7 / 52647

MrHeavyFoot · 05-19-2011, 07:12 AM

Anyone can shed some light as to what the fault code CDA7 is?

Happens pretty consistently, anytime I accelerate gently to around 100mph, I get the half-engine light and reduced power. This light goes away in about a minute and power is restored.

I'm running Procede V5 3-30.

CDA7 STATUS, REVERSE GEAR .
No idea
Do you get it in valet as well? if yes i would remove completely the procede and see if it still happens.

Oh my. Reverse gear!

Happens in valet too. Will try removing the Procede though I think it's probably the car acting up.

Thanks!

Anyone ever find an answer for this ? Mine just started throwing this code just happened to see it on the Procede when I was doing some data logging.

My problem just went away on its own. You could try the latest firmware?

Did any of you ever sort out what this was? My car has no obvious problems, but this is the one code that consistently comes up and doesn't seem to be related to "module unavailable." For example, I have code E18F on CCC, but that's something like "module failed to respond" which makes perfect sense, since I don't have a CCC.
