Part Number For Hall sender 3 Pin Flat Connector

LOL. Yep. What you have there is your Hall sender in a Tuna Can(tm) vestigial distributor or as you called it "mushroom" (I prefer Tuna Can). With it disconnected, the ECU (computer) will never start the car because it doesn't know what the spark timing needs to be. If the Hall sender is good you can probably just replace the plastic connector. I'll see if I can find the part number.

My friend Kate says that the part number you are looking for is 443 906 233. The same style connector is also used to supply power from the harness to many of the devices in the AAN engine bay, e.g. almost everything on the connector rack on the fire wall, i.e. power to the coils, knock sensors, etc. Should be easy enough to find/buy. Lable the wires 1,2,3 and remove the female pins from the cracked connector (use a pin removal tool to push them out the back). Reinstall in new connector.

Not having to much time, but i managed to , changed the Maf to Turbo hose, (very expensive 150E ), but was broken anyway. Changed TPS, and ISV, just in case, i have the exhaust taked down, and checked not to be blocked, checked for boost leak, i did not find, Checked and changed voltage regulator, now is ok, 14v, charging, CHanged ECU completly, same thing, Checked fuel filter, not cloged, checked MAP pressure line, ok.
I have make some more tests, and what i observed, are, If i drive, hard for a liitle time, that means, about 2-3 min, the exhaust, and turbo is glowing. The car stutter, shakes, when i reach exactly 0.4bar , it goes all the way to 1.4 if i keep my foot down, and the pressure is steady (on lcd display), no error codes on Vag-Com, I monitored the channels on Vag-Com, all in range . , and mpg , is low, last fill was about 18l/100km
Next step, will be te check wastegate, which hold vacum, as i tested, but to be sure, and to change N75,
As it happens at 0.4bar, i dont thing that is ignition, but i thing that is related, to one of this N75, or wastegate, but i still not understand why hits full boost, if so ?

Sorry mate but old is old. Could be fine but might be problematic. I think you have to start the missing and hesitation diagnostic from the beginning, checking everything.

Hi, i forgot update this thread, you have been right, small chances but it seems that the coil pack from both cars were broken, so i did a 2.0 tfsi coil conversion, no need to trim them, and is working great. Did an 13.9 - 400m, compared to 14.xx before. Thanks for advices,
