29DC from cleaning MAP sensors?

Is 29DC anything at all related to MAP sensors?

So I woke up this morning and decided to clean my MAP sensors because I was getting a hiccup every now and then. I've clean both before using carb cleaner, but this time around I used MAF cleaner I got from Napa. I took off the charge pipe and sprayed around in there also to get rid of some of the oil and then put everything back together. I hit the highway to see how it's running and all of a sudden I get the half-engine light and my car goes into limp mode. Pull over, restart, try again. Same thing, at WOT the car goes into limp. I do the resets using BT tool. Same problem, this time it will barely make it around the block and the car dies. I get a 29DC code, which usually means HPFP (I'm on my fourth). Clear the code and repeat, only to get 29DC over and over again. I did see the actual code for HPFP once (not 29DC), but only once. I disconnect the battery for 30 minutes, hook it back up, and am able to cruise around for 2-3 miles, then the car dies. Sputters and sputters then dies. I do this about three or four times until I decide to call a tow truck. Lucky for me, BMW has no loaner and won't touch the car until Monday evening.

Any ideas? No long cranks, car will start and then sputter and die. I am able to get a bit further the longer I leave it off.

Any other codes besides 29DC? Thinking it could be your low pressure sensor.

Plausible. I've had that replaced twice already, though I don't think the first time was necessary (hpfp, dealer didn't believe me but ended up replacing the lpfp sensor first then the hpfp when it didn't solve the problem). I brought the car in to BMW of Honolulu on Friday and they replaced the hpfp tonight (I didn't know there was a night shift!). I requested that they do an extended road test before they turn it back over to me tomorrow afternoon. Well see how it goes.

Side note: The dealership is replacing the hpfp under the 120k mile warranty even though I still have all my mods on. YMMV.

HPFP replaced under warranty and car is pulling strong again . . . for now.
