Ok, a new twist!. This might actually be worth reading!
After finally "clicking" that I was trying to use a Vag-com emulator instead of my "My Naff Code Reader" (major brain / beer fade) i managed to bring up the same 73 code on "My Naff Code Reader" but noticed reading the blocks that the new MAF was still measuring?.
I cleared the codes..still same problem(s) wont run more than 5 sec. checked the codes again, nothing, all clear. so just out of interest cleared them again and F me the friggin thing fired into life(Car) and is back working again like a new one!! WTF!?
So going back to all the member's who have replaced MAF's that have been replaced again and again because of this, something is up..
OK, with all these research and reading here the one thing that comes up more often than not is a second hand MAF "seems" to work on more occasions than a new one, either clone or original Bosch (sorry if im boring im trying to figure this out now in my own head as well!)
OK, when i originally plugged in my new "clone" direct from China the car ran like a dream, the fuel figures have never been better and a totally changed animal;
then it just didnt work; after trying to start next morning, nothing back to square one. Confused.
OK Q: how adaptive are the ECU's in these cars??? is it possible when we put in a new MAFand because of the "much improved figures" with a brand new MAFthat the ECU is getting all kinds of confused comparing the new figures to the old and thinking "F this, to hard..shut down!?" are the "old ones working more often than not because the trim figures are closer to what they were originally? Fuzzy logic??
I dont know these systems at all so I am just guessing. I have no doubt this fault is going to happen again if not tomorrow the next day so i will record the "My Naff Code Reader" readings and compare. but i bet my ass that these faults will slowly disappear!
Thoughts??
