Emergency brake system (AEB) fault.

Post by alibubs73 » Tue Sep 10, 2019 10:32 pm

My pulsar 1.5 Tekna diesel emergency brake system (AEB) lights keeps on coming on although there is no vehicle or obstruction in its way. A message appears on the central dash saying “ Front radar unavailable due to obstruction” and goes off sometimes whilst the car is still moving or when the vehicle is stopped and the engine switched off. Is there a simple solution to stop this or is it a workshop job? I have not had any problems with the car suddenly braking on its own accord.

have you tried cleaning the cameras/sensors, they may be dirty which can set off the system.

I too am experiencing this problem,show seems fine in dry conditions but warning often comes on during rain. Cleaned the black cover covering the sensor and front camera to no avail. Might pop down to main dealers and see what they think.

I have this intermittent problem too, had it since new. Same “ Front radar unavailable due to obstruction” message during heavy rain. Can come and go several times on a long journey.

Raised it with dealer on first service and they acknowledged lots of error codes for front radar and tried to BS me about clearing codes stopping the ECU looking for them again...yeah right.

I have read about other cars doing similar in the wet, makes sense that it could affect the radar I suppose. My dealer is so poor I just can't be bothered to go back to them about it, or the plethora of other issues tbh!
