Hey!
I recently replaced my tie rod ends along with the shocks and springs. I initially made an alignment myself and was satisfied with it but once in a tight curve at about 40-50 km/h the ESP went on and began braking on the exterior front wheel. The car was not sliding at all, disabling the ESP, I was able to take identical curves faster without any indication of loss of grip. I thought it had to do with the alignment, so as a first step I disconnected the battery (to reset the steering wheel position) and went to drive. Same problem.
I booked the car in an alignment shop and got a 4-wheels alignment done, I had too much toe-in but both front wheel were equal. Now I have maybe 0.05° of toe-in on each wheel, still the problem is still there (except the steering feels much better). They did not take steps to reset the steering wheel angle sensor adaptation (G85) when doing the alignment, so I took my VCDS and did it according to this tutorial

I also did the steering limit stop adaptation according to this tutorial (except I couldn't do it without driving) but it worked and I recovered the steering assist

Still the ESP issue is still present, I did it 3 times, no changes.
I then did the Lateral Acceleration Sensor (G200) adaptation, nothing changed... Values in logs are good, steering inputs are good when doing a graph on VCDS as well as wheel speed sensors. Of course I can only log them up to 35-40 km/h per hour, else the brake controller disconnects from VCDS which I think is normal, so I cannot get a log when the issue is happening.
I am a bit stuck here, I don't understand the problem. The ESP flashes if I take a rapid turn each side, if it's faster it would brake moderately the exterior front tire, if it's even faster, it will brake more. I am a bit worried to drive like this, because I feel like I could lose control because of him acting up. If I disable it, I can drive much faster without issues.
