U0199 to U0231 and U0234: door, seat, roof and comfort modules
A module stopped receiving messages from a door module (A to G), a door switch or window motor, a seat or mirror module, the folding or movable roof, the steering column, the tailgate, the rain sensor, the heated steering wheel or the memory settings.
SeverityLowLittle risk to the car, but the fault stays until it is repaired.

Modern doors, seats and roofs carry their own small modules on the network, so the windows, mirrors, locks and seat motors are commanded by messages rather than by a wire per switch. When one of these modules goes silent, the features it runs stop answering: a window that will not move, a mirror that will not fold, a seat that forgets its memory position. These faults rarely affect how the car drives.
What causes U0199?
- A wire broken in the rubber boot between the door and the body, where it bends every time the door opens
- Water inside a door after the door membrane or a seal has come loose
- A seat module unplugged, or its wiring strained by something under the seat
- Water from a tailgate or roof drain reaching a module
- A failed window motor or switch with its own module inside
What to check first for U0199
- Note which door, seat or feature has stopped answering
- Open and close the door while watching whether the fault comes and goes
- Inspect the wiring in the rubber boot between the door and the body
- Check under the seats and inside the doors for water and unplugged connectors
Can you drive with U0199?
You can drive safely. Check that the doors lock, the windows close and the mirrors are where you need them; if a door will not lock, do not leave valuables in the car.
Clear a code only after the fault is fixed. A code that comes back means the cause is still there, and a warning light left on can hide a second fault behind the first.

These are the generic meanings every manufacturer shares. Each brand adds its own detail, so your car's handbook, its service information and a qualified mechanic have the last word. OdoKeep has no connection with any manufacturer, and the app does not read codes from the car.
