coil replace and problem

[bolec]

hey. I have a problem with converiation coils and no one can help me.
engine is AAN. I replace orginal to 2.0 tfsi coils but engine don't start.
if I put a + 5 V on coil pin nr 3 e.g form the hall sensor i got spark. I was return to orginal coils and the engine is working on them. any ideal? please someone....

Harness power or ground issue. Who made the harness? Is it wired correctly? Did you connect the ground wires to the cam cover and/or intake manifold?

Here is the wiring diagram:

everything is solved correcty. if i plug If I get of coil and e.g to greed withe i put 5 v i have spark, but if i trying to power on engine I don't have...

everything is solved correcty.

Then you must have no problems.

Obviously you still have a problem. Somewhere. Unfortunately your English is very confusing so I don't know why you are talking about the cam sensor - unless it has failed and *THAT* is your problem. (Sorry )

Did you check the fuses above the ECU? In particular the one in the yellow S64/S115 fuse holder in the photos below:

if I remember well pin :
1 must be ignition +12V
2. ground to coil
3 signal wire from ECU
4. ground to valve cover

don't connect both grounds together (pin 2 & 4) .. it will not be good !

if you don't have signal to coil from ECU than Hall or Crank sensor is faulty.

Which is why I posted the original 1.8T coil pack diagram that was part of my original DIY in 2005:

i sory for my bad english.
i coneccted exacly like on the up picture. on new tfsi coil engine don,t start but on orginal one starts ! so i think fuses and senseor must be ok if it can start normaly.....

[bolec]

I check voltage between 2, and 3 rd pin of coil i when I trying to start engine i have: 0 V, 0,35 V, 0V , 0,45 V, 0V, 1,3 V, 0 V, 0,5 V, 0V, 1,4 V, 0V eg...
i probalby should have: 0V, 5V, 0V, 5V,0V, 5V,0V, 5V,0V, 5V?
or my measure is so slow..?

[bolec]

and i open ecu and what I see:
probably I have burned capacitor, anyone have with value i shoud use?
and the resistors sould look lite this?

and also i cant find s64 fuse..

[rs200]

sorry maybe a stupid qestion..
did you remove OEM POS terminals ?

[bolec]

yes

[UrS4boy]

...and also i cant find s64 fuse..

Well it isn't where I think it should be. However, I do see two other yellow fuse holders in the vicinity. The S64 will be one with a thick black wire coming in and a black wire with a green stripe going out.



Maybe the one at the front end (away from you) in the bottom black relay/fuse holder shown here (NOTE: Apparently your car doesn't have air bags? Is this correct?):

[bolec]

i dont have bags. but to this fuse is going black and yellow colors of cable

i got spark on new tfsi coils when i connect old colils too
some think like this :


but if i bear old coils i lost sprak on new tfsi coils too, any ideas?

Yes. Somehow, you don't have things wired properly. The OLD POSs should NOT be involved at all in this conversion. I think you are running them AND the POS-equipped coilpacks in series, which is 100% wrong.
