Spurious front parking sensor warnings
 

Just today, the inner drivers side sensor is sometimes giving sporadic warnings (red indication, so = it thinks its very close). Nothing there. It's so loud I think it's a dangerous distraction when driving. Sensor is clean, the connector at the back seems well pushed on.

Sometimes it works fine like the rest of them ; detecting closer and closer obstacles with greens than finally a red warning/ sound. Any ideas/ experience about this ?

For an aid like this to make driving more dangerous when it malfunctions, it makes a mockery of Volvo's reputation for design for safety. Better surely that the default should be an error message, not an alarm.

Mine drive me crazy, I have to go down an alley and it's constant, I don't have the side ones either, when the RED block pops up on continuous tone I still have 15 inches to the wall, I know mines had replacements as some are 100% body coloured and a couple of others are body coloured but have a black outer ring where they've not been painted fully,

I also find the City Safe thing will find a parked car when I least need it to, normally as I approach a bend in the road, or curvature I should say,

Kinda negs their purpose tbh as you still have no idea how close you really are to things.

Irritating yes, but I had 2 new VW s with emergency braking that deployed for absolutely no reason whatsoever. One of those was very dangerous because I had a car behind me at the time.

I have exactly the same with one of my front sensors. It works perfectly but every now and again it beeps for no reason. I remember it first did it a couple of years ago when it was raining really heavily so I suspect water may be something to do with it. I've cleaned it, checked the connector, and sprayed it with some water repellent stuff but it still does it.

It's fine today. I'll spray the sensor and plug/ wiring with silicone. shouldn't really need doing on a "quality" car,

My Cross Country used to do the same, I’d be sitting in traffic and then my sensors would go mental showing something that wasn’t there…. It be Alien’s walk amongst us. Very strange

TT

We are talking about iffy sensors annoying us at parking speeds. They get dirty, or faulty.
We replace them or moan a bit. It happens.

Up the speed a bit to emergency assist / city braking sensors and it gets dodgy. I was lucky someone didn't run in the back of my premium model car.

Then go to autonomous driving and imagine faulty sensors then. The trouble is that we are a sensible bunch who will get faulty sensors sorted. Others wont.

Were we largely better off in the days before cameras and sensors were introduced on cars or do they provide a net benefit?

Also, are younger drivers more reliant upon sensors and, therefore, possibly a bit stuck when they fail, or do they cope?

Just a couple of thoughts from someone who used to manage without them but who does actually find them useful.

Rear ones are handy, fronts not so much so they just add noise imo, new ones from the Bay are £23 or near that price anyway.

Resurrecting a slightly old post (sorry, not sure whether that's better, or should start a new thread):

my wife hit a pheasant the other day on the road, which seems to have knocked the front right parking sensor. There is now a gap where it should be, but I think it must have been knocked inside the bumper cavity as when driving at parking speeds it beeps constantly. I had a look behind the bumper, but it seems one cannot get to it without removing the entire bumper. Is that correct? Would it be a big job to get it either reinserted correctly (if it is just inside the bumper) or replaced if it was knocked out altogether? Approx cost (in the UK)? thanks!
