my mate had vag com on my car, and he said he needed to reset the odoption levels or something for the maf??
unless it was a big way in saying now there a new maf mete he needed to reset ecu lol
and bill when u took my car for a road test it was 100% not running on 3 cylinders was it

Thanks for the info on the ignition amp, I dont own one of those cars and just spotted it mentioned on another forum.
With a new MAF the ecu will need resetting? if the old one was faulty wont it have been giving bad data to the ecu?

right. the new MAF was definatly the wrong one. the sendor inside looked totally different to my original one.
iv cleaned up the lambda's with some WD40
iv cleaned up the original MAF and put it back on and its pulling alot better and isnt sounding anywhere near as bad as before but is still misfiring a lot.
do you think my MAF could just be dodgey and i need one that is bang on for my car?
just not quite sure what it could be?
also soldered the bypass wires to the resisters while i had my head under the bonnet as one of the wires only had one thread left onto the resistor!

I had this exact problem recently on my car, did coilpacks + plugs + MAF on my car and it turned out to be a dead Pre cat Lambda sensor and it was overfulling like F*** Causing missing on boost. Did'nt throw any codes for it strangely enough.
I reckon from this if you put the right MAF on there, reset the ecu, clean the plugs then run it and see how you go.
If it does the same then the maf is definately ok as its new, then you can take out the plugs and see manually what they look like ie if they are black then you have overfuelling. as air filter, maf etc are okay it probably would be the issue described above.
what do other people reckon?
jus been out in the car now reset the battery it went fine for a while but have had no luck in findin vag-com that i can use on my car usin windows vista? i have a de-cat and the lamba sensor that is after where the cat used 2 be is not plugged in will this cause this kind of problem as i thought it would of been mapped an they do not require it or does it still need 2 be there?

It suggests that you need to plug the sensor in, but that it needs to be in a type of sleeve so that it reads fresh air.
I think this could well be your issue. it may not but its another tick!

gonna see if swapping the maf again. when i put my old one back on it runs rough yeah but nowhere as near as the brand new one i tried.
so i tried running it without a MAF and it runs loads better but does still misfire quite a bit on boost.

i dont have the tools to take out the sensor itself but on the box tyhe part number reads
AMM19614
213719614010
so are the last three digits of this 010 when they should be 040?
i got a 180 mile trip tomorow. if its popping & banging when the MAF is plugged in will i be ok to do the trip with the MAF unplugged?

maf unplugged your goin to cause damage imo
ecu wunt know how much air is getting pulled through, air fuel mixture wunt be bang on will it if its unplugged surely

car seemed to have been cured yesterday when i unplugged the MAF. got in it today and the ecu light was on and we are back to square one again. misfiring like hell under load! so i plugged the old MAF back in again and still does it the same. i just dont understand?

scarp it lol
cupra owning at its best that is.
get the full version of vag com mate! the free version only scans a certain few faults the full version should pic up the fault for you.
