First Timer: BT Scan Results?

shoes · 10-22-2009, 11:55 PM

Well I just got my 'JB3 + Basic BT Cable combo' and I decided to mess around with the BT, just to get acquainted with the software.
My car is used, I've had it about a month now. It is completely stock other than a BMS drop-in filter that I just installed. I have not yet installed my JB3 and I'm now reluctant to do so after seeing the codes I found - no sense in installing if I have to pull it right back out.

Anyway, so I was looking through the folders on the left of the BT Sofware, looked through the fault codes, fortunately, nothing was there.
I saw Shadow Fault Codes and decided to check it out.

These were my results from the Shadow Fault Code folder:

Code:

Current Shadow Fault Codes	 		
 		
2AAF:
2AAF Fuel pump, plausibility
Error will not cause a warning light
Error is not currently present
Test conditions have been completed
Short circuit or signal interruption

 Freeze Frame Information 
Odometer	47584kms	29567miles
fuel pressure before mass control valve	4,627.46	hPa
Engine speed	1,568.00	rpm
voltage Kl. 87	13.81	V
injected mass of fuel	9.00	l/h
Event 2 
Odometer	47584kms	29567miles
fuel pressure before mass control valve	4,797.27	hPa
Engine speed	2,016.00	rpm
voltage Kl. 87	13.81	V
injected mass of fuel	11.00	l/h
Event 3 
Odometer	47872kms	29746miles
fuel pressure before mass control valve	4,500.10	hPa
Engine speed	1,344.00	rpm
voltage Kl. 87	13.91	V
injected mass of fuel	7.00	l/h
		
 		
2A17:
2A17 DMTL diagnosis module tank leakage, system failure
Error will cause a warning light
Error is not currently present
Test conditions have been completed
Timeout

Upon searching the forum here at E90, I have come to the conclusion that these 'shadow fault codes' are nothing to worry about. Is this true? or am I looking at a dealer visit in the near future?
I have not received any warning or check engine lights.

Through searching again, I read that the other code was something about the gas cap not being secure or something of the like. Anything to worry about with this?

-So what do these codes indicate? A fuel pump on its death-bed?
-Should I proceed to install my JB3? Will the tune push my fuel pump over the edge?

Need some experienced advice.

EDIT: Checked the Stickied topic 'Bavarian Tech Code List' and looked up both codes.
For 2AAF it states: "Very common code stock and modified alike, does not trigger a CEL. Just ignore it."
And no explanation for the other code (2A17).

ya the 2AAf is nothing to worry about. the one to worry about is the 2FBF that will throw a light though. That usually mean the pump needs to be replaced. That is the one I got and had to replace it.

Cool thanks.

I panicked a little bit when I saw the codes.

So I'm OK to install my JB3? I wont be taking it right back out for a bad fuel pump fix?
What about that other code?

HPFREAK · 10-23-2009, 01:05 AM

You should be fine to install the JB3. the other may be because of the gas cap. give it a check to see if it clicks when you take it off and on. That is kind of common as well.

shoes · 10-23-2009, 01:17 AM

I will double check the gas cap in the morning.

Thanks Brad!

No problem

Have you been smelling fuel vapors or anything?
