the last couple of times that it's rained heavily my parking sensor has been stuck on.

both times the sensor had eventually returned to normal the next day.

has anyone else experienced this ?

my exeo is still under warranty but i'm not sure how i'd convince the dealer that there's a problem when the sensors work 99% of the time - any ideas ?

Had this on my passat. dealer couldnt find a problem, it eventualy stoped completly. you can tell which one is faulty by listening to the sensors as the ones that are not faulty will have clicking sound coming from them, Its very faint and you need to have your ear against sensor.
On my passat I found the faulty sensor and moved it to another position and it worked so the problem was in the harness.

so surely the dealer should be able to do much the same ? i'd prefer to get this issue fixed before my warranty runs out !

will have a listen anyway - thanks for the tip. :)

Hi, I have the exact same issue! Mine started about 2 weeks ago after the stormy Monday we had. Now, when it rains (or the car has been washed), for about 24-48 hours afterwards my parking sensors go haywire. I either get continuous bleeps when in reverse, or one solid bleep, or nothing at all.

Mine is an Exeo ST Sport Tech (MY13) - fortunately still under warranty so it is getting booked in tomorrow!

They can fix the stuck-in cupholder at the same time...

Let me know how you get on - I will do the same.

Water must get into some of the units.

I know that when it rains the sensors will sometimes sense something is there and give a false warning though...

I've had my 2013 Exeo ST Sport Tech for two weeks and it's now doing the same thing. Washed it at the weekend and the continuous beeps in reverse are still there after three days. Did the dealer fix it for you gletts?

Hi Gerry

Not actually got it booked in yet - hopefully will get time to ring the dealer today. Mine still do it after car washed or it's rained hard, for about 2-3 days afterwards then OK again.

Had another, seriously dangerous thing happen last week too which I'm going to put on a new thread - worth you checking this on your car too as it's the same model/age as mine.

The plastic cover on the footrest, to the left of the clutch, came off and got jammed under the clutch pedal. Fortunately it didn't go over far enough to get jammed under the brake pedal, but was still serious enough that I couldn't push the clutch down at all.

It looks to me as if there should be a screw holding it on (near the top), in addition to the flimsy plastic clips. But on my car - the screw is missing so I suspect it was never fitted.

Worth checking on yours and also that, even if the screw isn't there, the plastic cover is on securely!

I'd be very interested to know if the screw is present on yours or not - perhaps you could let me know - more ammunition for when I speak to the dealer and also write a letter of complaint to SEAT customer services!

Thanks,

Graham

OK - what is happening with these parking sensors. One of my colleages has an Audi A3 56 plate, so presumably same/similar sensors. His has done the exact same thing, in the last 3 weeks.

Is it to do with the weather getting cold somehow?!

Hi Graham,

Yeah my sensors appear to have corrected themselves after I parked on a slope. Could it be water sitting in a channel or something similar?

Just had a look at the footrest and the screw is there and the plastic cover is on securely. Glad to hear it didn't lead to something horrible.

Thanks for checking Gerry. Gives me more ammunition for the dealers and a letter to SEAT customer services!

With the sensors - my car is parked on the level at home and at work, and I don't think I've parked on a slope recently. Think its more likely that water is getting in to one or more of the sensors, and either takes a day or two to dry out naturally, or as you say maybe parking on a slope allows it to drain out.

One other thing - when my car is cold AND the weather is cold, the turbo sounds very "raspy" like it's vibrating, but only for the first 1/2 mile or so. Does yours do that?

Cheers,

Graham

Graham,

I'm not aware of a "raspy" noise. I must admit I expected the usual clatter from a cold diesel engine on startup but I've been pleasantly surprised by how well it sounds. I suppose it's been tuned by SEAT to sound a bit more sporty than I thought it would.

OK folks - an update on the parking sensor issue.

My car was at the dealer's last week and got the usual "we can't make it go wrong", and "can you bring it in when it's not working".

Then when they moved the car after phoning me - fortunately for me, it went wrong so they were able to get the fault code.

They have ordered a new sensor for the bumper, just waiting for it to arrive, go into the bodyshop to be painted, and then my car will go in for a day to have it fitted.

Meantime the cup holder that they "fixed" has now broken again.... anyone else have trouble with that, where you push it in, and it gets stuck in? Very irritating.... only does it when the dash is warm though so must be expanding plastic I think.

mine is booked in later this week but i'm also dreading the fact that they won't be able to reproduce it and fob me off.

i'll pray for heavy rain on the day i think ...

unfortunately and not unexpectedly, my sensor wouldn't go wrong when i dropped it off for them to have a look.

i'm sure i won't have to wait too long for it to rain again - just have to hope that the dealer is open when it happens.

sigh.

Well guy's,
I've had the same parking sensor issue for the last 10 months, caused by rain and even washing the car, dealer has fitted 5 sensor's in total, ignoring that I have said I thought it may be corrosion in the wiring loom, finally they looked at the loom and did a fix, to replace corroded section, however it only lasted a week, so they have ordered a loom, but thats on back order, so waiting again.

Hi all

An update on the parking sensor issue.

Mine has been in 4 times for this now. Sensors replaced, connections re made ... all fine til it rains or car washed, then they stop working for a couple of days OR, worse, don't work correctly. I can't trust them now and dealer cannot find anything wrong.

Anyone else who had this problem had any developments?

A work colleague came up with the 'helpful' suggestion of having them disconnected.... hardly the answer though!!

Hi All,

update on parking sensor issues, dealer has had the car for 5 days, on 2 occasions to sort this out, so far several sensors have been replaced, rear wiring loom for the sensors and the control module, the fault has returned, this is getting a bit of a bind now, over ten moths and no fix.
I have VCDS and scan the car when the fault occurs, and it shows that the inner left sensor reading faulty, you can watch the readings in measuring blocks, as the sensor has a base reading of 255cm, and the faulty one the reading fluctuates up and down, when parked in an empty car park at work and no where near any object.
I have also noted on the scan, that I have an incompatbile software problem in the engine ( with the transmission module) my car is manual so is not fitted with a transmission module, very strange.
Is there another member with VCDS and an Exeo that could scan their car and send me a copy, so that I can check the coding on my modules, within the car ?

Hi,

Just to note, the parking sensors have never thrown a fault code, when not working.
You have to check them using measuring blocks in VCDS or using the factory software, we have similar problems with Toyota sensors, however, our gt86 fault finding software does not allow for any readings to be taken, so we have to listen and feel the sensors to find the defective ones.

My parking sensor light button is flashing and a different beeping noise constantly from the back. I don't know the problem. And they are not working. Is it to do with the fittings of the wires under the bumpers or what? Help please

If it's a constant noise, you will have a sensor that's not working, you can check them by listening to them, they give a clicking noise, if you put your ear to them, or se vcds software to locate the faulty one.
