Thanks. When I get off work I am going to try and see if it solves my problem.
what do you mean same issues? this tsb doesn't involve misfires... its just a check engine light.

so i got the wires from the dealer and made some progress. I couldn't remove the wire from the connector so I just cut the wire and used 2 butt connectors to connect the ground wire to the 2 wires I connected together. I was in a rush and broke the purple piece but it didn't matter bc I think all of the wires were glued in.
So far no CEL and I drove it like I stole the car......its funny now when my A/C cuts on the revs jump up... Car gets slow so I guess its back to normal
If you look at the diagram the terminal for the ground or "earth" (brown) wire is labeled T6a/1
T6a = the designation of the actual connector itself
/1 = the pin/terminal number of the wire in question
So you'd want to cut the (brown) wire coming out of terminal #1 of the connector.
On my 2003 jetta, this wire is ORANGE , but it is still coming out of terminal #1
Also because there seems to be confusion, the black wire with purple stripe is the constant power feed into the coil pack. The color in the diagram is labeled sw/Il
sw = black
Il = violet
As there are so many freakin engine codes for vws, make sure you have the correct wiring diagram and double check it before you cut.
A side note on butt splices: The proper way is to solder/shrinkwrap in a splice. Using the crimp style butt splices are effective but over the long term may weaken the wire and promote corrosion. Buy hey man, its your car, do whatever the hell you want.

I had the tsb ground wire done by the dealer when the car was still under warranty to solve the CEL and open ignition circuit codes. It helped for a while but for the last several years I constantly get the P1355, P1358, P1361, P1364 codes shortly after I clear them. Car runs fine though, and I have removed the battery plate and checked the wire and tightened the nut but the codes continue. It's original coilpack, nothing aftermarket on the car. Has anybody else had this tsb NOT work?
does this effect the 1.8t engines too? I have replaced the harness and only have the ground on top of the valve cover and has open circit codes/misfires, and 1.8t has a different coil pack wiring than the 2.0 please help have been trying to solve this since i replaced the harness a week ago..
