Thought I'd found it by searching Bentley but only on the V10 and another production code (=newer) engine. Mine's the BFM as are all US 2004s.

Trying to run down codes including a trail to fuel pumps and would love to log pressure, pump status, etc. for each, but I searched last night and no luck.

Do all these cars (4.2s) need the EGR Adaptation MP talked of in the past?

More details later, sorry gotta run...

I can't find one anywhere in the (non encrypted) label files or the parts list.

Have a look at these general MVBs: http://www.ross-tech.com/vag-com/m_blocks/
If you don't find one, you know where to ask...

Thanks, Jake. Yes, I know who. Either some EE who can speed through a wiring diagram like we read the comics; or my Laird Uwe who might know the correlation of these codes - they all occur together and the car stalls. She was kind enough to provide a full set just now, for my immediate use. Didn't quite stall as my 11-year old is getting good at save/clear codes! It is happening with increasing frequency, every 40 miles or so.

Please to enjoy le codes:

Then there are usually these codes as well, not sure if caused by the stall or if they "mean something":

1 Fault Found:
18265 - Load Signal
P1857 - 000 - Error Message from ECUThe first two codes are almost always there.

Anytime the 16487 MAF P0103 occurs the car stalls. It only occurs at or near idle, usually after driving at 45-55 MPH for 5-10 minutes.

Once, the car stalled without the last two, but usually they are set.

I know there is a common connector where these converge that's broken! Or at least they are related somehow.
Also that big pucklike throttle control valve makes me nervous. Can't find much info on it.
Another thought I'm entertaining is to swap the old MAF back in. Bosch doesn't send out defective ECUs right? I fixed the EGR lines and airbox since then....

Naturally, and as usual; thanks in advance for any help.

Going out to look for vacuum leaks. You can still do that with propane, right? I've got a big full tank that won't connect to my grill. Hmmmm.

Post it up over there - you're verified IIRC.
No offense, but you're not likely to find anyone here who knows, yet.

I'm one of the few there who know the C and D chassis, but there are some top notch guys who have access to a lot of info - and experience.

Propane you say?
No propane accessories? Dammit BobbyTom !

Reminds me of my grandfather 'testing' for gas leaks with a propane torch or a match.

FWIW, I liberally sprayed the manifold/block juncture with CRC MAF cleaner without result. Then I thought I better verify its effect , so I disconnected the vac tube from the B/W check valve and sprayed into the tube going straight into the manifold (I guess)... it took a surprisingly large amount to affect the idle. I then took off the fuel pressure regulator tube and it had virtually no effect.. I sprayed first a little then a lot into the tube and finally got a slight reaction. No DTCs triggered by all this...

One old school test I performed was manifold vacuum; it was not exactly steady at idle, but varied +/- maybe five pounds. Measured at FPR tube. Revved to ~4000 RPM but vac performed as expected, smooth and up & down.

Very tired and sore. And up too late...

Have you checked the wiring from the maf to ecu for continuity and resistance as suggested in the other thread.

Its unlikely that the new maf is faulty but not impossible.

If the cable from the maf is dodgy then its entirely possible that the ecu is getting a reading thats outside the normal operating parameters and it doesn't know how to respond.

Check the wiring and if your satisfied with it, log the maf when your driving.

aTOMic

I deoxited the large plug to the ECU in the cowl. I will have to educate myself on how to determine which is which so I can "ohm it out".

I'm attaching one file (EDIT: or not...) which I hope are useful. It DID stall once when I was data-logging, I hope someone can figure which and it's useful.

aTOMic

So far all I can report re the health of the new MAF is in measuring block 002 at 5000 RPM, my wife thinks the highest she saw was 280. Probably 80% throttle.

I've got all these logs I dunno how to post. Or if they would even be helpful.

The evap one @ 80 MPH was the insufficient vacuum. Just level ground, nothing remarkable

All the other logs are too big for this forum.
CSV files show as "Invalid File"...

Steep learning curve with something this complicated, I suppose.
And yes, I know I'll have to get under it at some point...
