I purchased an 041 MPS from a fellow board member after finding a small vacuum leak on my current MPS. The car ran really rough with the 043 and I checked the part # on my current MPS and it is an 019? I cannot find any data on an 019 MPS - anybody have info on these? Is there a source for these?

"019" is only a small portion of the part number. Perhaps you'd get an answer if you were to give us the whole number, or even both the Bosch number and the automaker's number. The Bosch number will be x.xxx.xxx.xxx, and the other number will be (if it's VW or Porsche) xxx.xxx.xxx.x (the last x representing a letter).

No info here on the 019? Had already searched this - could only find info on the 037, 043, and 049. When you say "cross reference table" are you referring to the compatibility table - am I blind?

ah so you have a 1.7 I will assume....there are a couple early MPS numbers he doesn't have on there because its based on 2.0 djet. I believe I have a couple 019s for my 1.7 and they all work fine.
like the cap'n said, give us the whole part numbers...does the other number end in 51A or 51E? where did you get this MPS from? |

The 1.7L should be running a 049 MPS. A 019 will work fine if its still virgin and hasn't been tampered with. The difference is inside the 019 early 1.7l MPS has a WOT stop built in to the cover while later MPS havea different cover design.

Sorry for the (IMG:style_emoticons/default/hijacked.gif) but am I reading that compatibility chart correctly if I believe a "037" ECU is compatible with ONLY "037" MPS's?

The part numbers are:
0280 100 019 VW 022 906 051A Bleyseng, in response to your PM, it does have screws not rivets and it has three ~1mm holes (about the same place as the slots in the 041 I have) and the epoxy is intact over the large screw on the end. |

Since it has screws, it has been "rebuilt" by someone. All MPSs were riveted from Bosch.
0 280 100 019 = Porsche 914 1.7L, 05/70 to 07/71 Interchangeable with 0 280 100 049 |

My '98 Bosch FI catalog does not show either the 0 280 100 019 or the corresponding VW part number (022 906 051A) listed. None of the Porsche references I have make any notation of either p/n. I did a Google search on both p/n's and didn't find any references that verify compatability with the 0 280 100 049. Be aware that a 022 906 051A is NOT the same as a 022 906 051E (which is listed as the same part as the 0 280 100 049). My guess is that the 0 280 100 019 / 022 906 051A is a discontinued T3 or T4 part. As with all MPS's designed for T3 and T4 applications, it's likely that the 019 has exactly the same part load mixture as the rest of them. The only differences likely are the onset vacuum for the transition from part to full-load, and the extent of full-load enrichment. A good 019 can very likely be recalibrated to match the 049 spec. |

Bosch ESI 97/6 I'm unfamiliar with that reference. What does "ESI" stand for? Is this a book or a fiche? Thanks... Should have looked it up first - it's the Esi [tronic], right? Looks like a shop-only reference DVD. Good info, thanks. |

I have a '73 1.7 and 2 51As and a 51E and all work great.
I know everyone says all MPSs come with rivets and I believe it, but the two 51As look original as can be, expoy intact, and they both have the same screws and sealing compound.....I have another blown one and its the same too. I've always wondered if the earliest ones were screwed. |

right....and you guys have a lot more knowledge on the subject than I do so I am inclined to believe that theory.
Its more a curiousity thing at this point. |

All MPS's from the Factory were riveted! geez....screws are used by the rebuilders.
The earliest MPS I have seen was a 003 on my early 70 with the original motor. The 019 are from the 71 cars like Slits said based on my observations and came on the 411/412's too. The only differences I have found is inside the cover where there is a raised WOT boss vs the 049 which has the same flush cover as the 037 and 043. You cannot make a 043 or 037 MPS out of these early ones unless you swap the cover as it interfers with the WOT setting usually. I have set up/rebuild about 50 MPS's now mostly 2.0L ones to keep these cars on the road with the right FI calibrations. Oh, yes that is right. The 037 MPS only goes with the 1973 037 ECU also using the 017 CHT and ballast resistor. |

Geoff - Is there one I can swap it with, or do you know of a source for the 019's? How about repairing the 019 I currently have?
