U0155 to U0163, U0232, U0233 and U0235: instrument cluster, displays and driver aids
A module stopped hearing from the instrument cluster, an information display or head up display, the parking assist, the warning chime, the compass or navigation, a blind spot sensor or the radar for adaptive cruise control.
SeverityHighCarrying on can cause expensive damage, so deal with it now.

The instrument cluster shows the speed and the warning lights and messages that come from other modules over the network, and on many cars it also holds the odometer and part of the immobilizer. The other modules in this group warn and inform the driver: chimes, displays, parking sensors, blind spot monitoring and the distance sensor for adaptive cruise control. When one goes silent, its feature stops, and if it is the cluster you can lose the speedometer and every warning light.
What causes U0155?
- A blown fuse for the instrument cluster or the display
- A loose connector behind the cluster, often disturbed by dashboard work
- A radar or blind spot sensor knocked out of place, or with a damaged connector after a bump
- Water reaching a sensor in a bumper or a mirror
- A failed cluster or display unit
What to check first for U0155
- Check whether the speedometer, fuel gauge and warning lights still work
- Check the cluster's fuses and its connector
- Inspect the bumper and mirror sensors for damage and loose connectors after any knock
- Ask whether a sensor needs calibrating after bumper, windscreen or alignment work
Can you drive with U0155?
If the instrument cluster is dark, or the speedometer and warning lights are gone, drive only to a nearby workshop, carefully. If only a driver aid or a display is missing, the car is safe to drive, but do not rely on the parking sensors, blind spot warnings or adaptive cruise control until it is fixed.
Since May 2018 an engine warning light that stays on is a major defect at the MOT, so the car fails until the fault is fixed.
