Sorry about the long post.

I have a 2022 model year 2.0 TSI 4x4 equipped with DCC. I have been facing a strange but a crippling problem with my Kodiaq from day one. The DCC often puts all fours dampers into what I call "Zero damping mode". All 4 Shock absorbers offer absolutely no damping at all when that happens. Suspension makes loud metallic noise while going over even minor undulations and expansion joints and both alloys and tires get damaged and subsequently develop severe wobbling. It feels like sitting on a stone that's hurtling down the road. I have taken the car to multiple Skoda dealers several times. Everything appear normal when they take the TD but I hit the problem randomly on my daily drives. My car has chewed up about 22 tires and 18 alloys in the past 3 years and 30k miles.

I was clueless about what triggers the problem. However, over time I observed a pattern. The problem doesn't occur if I follow a certain sequence when I start the car.

The sequence that works - Unlock the car, open driver's door, get in, close the door, wait for L&K animation on instrument cluster to complete, wait for about 4 more seconds and then start the car.

Sequences that trigger the problem (almost always):

1) Start the car before L&K animation completes

2) Unlock the door, get into the car and let the animation to complete but start the engine only after instrument cluster turns off (it turns off after few minutes if the car is not started)

3) Unlock the door, open and close. That will trigger L&K animation. Then quickly open the door while the animation is in progress. Close the door after the animation completes and start the engine

4) Park the car after a drive, turn off the engine and wait for a few minutes but don't open any doors. Instrument cluster will turn off after a few minutes. Now start the engine.

The only way to prevent and recover DCC from bad state - Turn off the engine, get out, close all doors, lock doors, wait for instrument cluster to turn off, open the door, get in, close the door, wait for animation to complete and then start.

Another interesting observation is that changing DCC modes will have no impact on damping force once DCC goes into the bad state. Also, how stiff suspension feels depends on how soon I start after the L&K Animation completes. Waiting for about 4 to 5 seconds after the animation seem to properly initialize DCC. I am soon going back to the dealer armed with my observations. I have also conveyed my observations to Skoda Customer care.

I think some HW or SW issue is preventing DCC from being initialized properly under some scenarios. I read lot of complaints about DCC equipped VW and Skoda cars on online forums.

Has anyone experienced similar problems. Also, any guesses on what could be the underlying problem?

Thanks

what's been done?

I've been told there is a reset possible. But it can only be done with all four wheels in the air.

Have the dampers been changed? If not, why not?

In a state of desperation, I tried two things..

1) Drove in Offroad mode for few miles as suggested in https://www.volkswagenforum.co.uk/threads/new-model-tiguan-dcc-problem-no-difference-between-modes.25834/. I never engaged Offroad mode until I came across that thread.

2) Took live data from Control Module 14 (Wheel Dampening) to monitor current reading at the damping valves. Used OBDEleven dongle.

I don't know which one helped but I am unable to recreate the original problem anymore. It appears that one of the actions has put DCC software in a proper working condition. Hoping to put this issue behind for good and enjoy the drives.

@jarneevans I see your location is India. Important.... Are you serious about the tyres & wheels you have replaced.. More than £7,000 spent! Are you driving hard at sleeping policemen / potholes etc? Where has the car been to to get the fault diagnosed at . What do you expect Skoda Customer Care to be doing? SKODA INDIA and CZ are the ones that the Dealer / Technician need to speak with not just you complaining or speaking with some Call Center handler. HOW MANY SKODA DEALERSHIPS ARE THERE IN YOUR AREA?
