Hi,

I have a Superb II 170hp Elegance and have had a rear parking sensor problem since the day I picked up the car.

It is the second sensor from the left and beeps continously as if the car is in very close proximity to an object. It initially began with the odd solid tone and the display on the radio would show that red band close to the car graphic to indicate close proximity. It then became a constant problem. As soon as I put the car in reverse the sensor would activate. I took it to the dealer who changed the sensor and the problem was back before I left the garage. They made up a wire loom from the sensor to the control box and that solved the problem. They ordered a factory loom and fitted it a few weeks later. They washed the car as a courtesy, I sat in, engaged reverse and the sensor was on full tone again. Went home and after a day or two it began to work fine. Was careful washing the car until last weekend when I washed that area with the powerwasher and now the problem is constant again. The dealer has ordered a replacement control unit and will fit that tomorrow to see if that will help with the problem. Despite using the powerwasher on all the sensors, it is the same sensor every time.

Has anybody had this problem?

Has anyone any solutions?

Is changing the control unit a waste of time?

This is taking from my enjoyment of the car and I want it sorted.

All help apprecaited.

If it's not a fault of the sensor or of the wiring loom,then it's the control unit.If changing the control unit won't solve this problem maybe the replacement sensor was also faulty or maybe it's really hard to do a proper wire insulation.

Very very occasionally I get this same fault, if I take the car out of reverse and put it back in again it goes away think I've had it happen three times.

Hi,

I collected the car on Wednesday after the garage changed the control box. So far so good, but I am paranoid about its next wash. I will definitely avoid too much pressure in the area of that sensor.

When the problem is present on the car, it makes no difference if I take it out of reverse a thousand times. It just will not go away. I hope that its finally sorted.

I'd be interested in the outcome on this as I have the exact same problem, with the exact same sensor!

It is really annoying, and concentrating with the sensor beeping all the time is not easy!

Hi Gtec,

Still working OK. However, I have not washed the car since as the weather sucks really bad and haven't been brave enough to face the cold.
