From what I understood, I have to open the ecu and ground a pin for 5 seconds, is that correct?

Yes. Pin 24 of the IC labeled 29f800bb.

Ok, what's the other one cricled in red, do I have to mess with that one too? I guess I'll have to wait untill tommorrow or monday because I don't have a torx screw driver big enough for the screws in the ecu, I've managed to get 2 of them out with a flat head screw driver and a set of pliers but the screw driver failed at the third screw and got broken. Is there no way around without grounding that pin?

you can use either red pin for bootmode. There is also a third location on the ram chip, but they all do the same thing. One of them MUST be grounded before and during powerup of the ecu to enter bootmode.

@prj I'll try that after I will flash the 1024kb ecu although it does not stay connected even with the original 512kb ecu which I don't it's without immo.
All euro S4's and A6's have immo, also the 512k ones. |

Sorry for the delay guys, I had some other priorities in my life. So I grounded the pin and it does the same thing, it won't connect in boot mode, now it won't even connect on kwp2000 protocol, check the pictures. I have no idea what happened, I hope i didn't brick the ecu....

Nefmoto won't do bootmode flashing, you need galletto for that. If you shorted any of those pins together, you could have damaged the ecu. Where are you located?
Read the "galletto software edited with proper english" in the flashing section. The software for bootmode is provided, as are instructions on using it.

I'm in Romania, I guess I'll take the ecu to someone here who does proper bench flashing for a living becuase this is over me, fi my ecu is damaged he can replace the chip and disable my immo and then I shoul be able to do the flash with my kkl cable and the harness I made from my psu. Untill then I guess I'm screwed....

Ok, I will get my ecu in a few days back, until then I have a few other problems but I don't want to create a new thread, hope this doesen't bother. My car started acting really weird the last few days and today it went in limp mode, that's what I think. I can't rev it past 1100rpm but when I can it sounds like I have anti-lag, it only sputters and bangs through the exhaust, I've barely driven the car home. I scanned it with vag-com and I got these codes:
16705/P0321/000801 - Engine Speed Sensor (G28): Implausible Signal
16622/P0238/000568 - Manifold Pressure/Boost Sensor (G31): Signal too High
16490/P0106/000262 - Manifold / Barometric Pressure Sensor (G71) / (F96): Implausible Signal
18010/P1602/005634 - Power Supply B+ Terminal 30: Voltage too Low (What the heck is this??)
16486/P0102/000258 - Mass Air Flow Sensor (MAF/G70): Signal too Low
I want to know if I can swap a4 sensors or other vag car sensors in, this is only a temporary solultion as I will go single turbo the next few months and I will buy everything new. I am asking this because I have a friend who has alot of v6 a4's and 1.8t a4's and other vag cars and I can get the sensors really cheap. I posted this on audizine but apperenly I didn't get an answer for my question. I don't want to sound stupid or to be a cheapskate.

Sounds like it's time to throw the piggyback into trash.

Before doing anything you should know how to
1) read/write your cluster
2) defeat immo
3) flash an ecu on the bench with bootmode
4) flash an ecu on the bench w/o bootmode
5) flash an ecu in car over obd
until you can do all 5, please do not proceed any further.
unless 6) is ditching your piggyback.
