Default D3 suspension issue

Ok so I was having an issue with the whole passenger side sitting lower than the drivers side and my standard and automatic settings not working. today i replaced the suspension control module and everything is operating right now after calibrating the computer with a snap on souls ultra.

But now the car sits perfectly level in standard mode but when i put it in dynamic the passenger front drops down about 3/8" to 1/2" lower than the drivers front. and the rear is only of by about a 1/16th probably due to the passenger front dropping to low.

can anybody give me any idea what might cause this.

It wouldn't be a problem if running stock wheels and keeping it stock height but i am trying to get the stance right with adjustable links and 22" wheels

thank you

Leak in the air system or messed up level sensors.

'Stancing' a vehicle and putting the wrong wheels on can make things interesting.
Got a complete VCDS Auto-Scan to see if there are any DTCs ? [read: not cheap code scanner]

No idea what a 'snap on souls ultra' is, but it won't do the same job.
How many mm did you lower/adjust it at each time? It's a tricky system....

I am at stock rod length right now. trying to get all the bugs worked out before I lower the car. The snap on scanner is not a cheap tool. about $4k. it reads and does just about everything the vag com does except it works for just about every make and model vehicle. this system is making now since right now. car sits perfectly level in standard mode. maybe it could be a height sensor. I guess there could be an issue with the sensor once it hits the area it would be in while in dynamic.

Cool - will have to check out the SnapOn tool, sounds interesting.
You'd be amazed how many people think a $29 tool is adequate to do real work

Agreed - work out the bugs before adding the lowering links.
Sometimes the level sensors get tweaked off angle and provide erroneous info.

The vehicle isn't settling overnight on one corner is it?
Doesn't sound like a leak, but that's always in the back of my mind
