From searching I can see this has been covered before in various forms, but just to make sure I have the right end of the stick....

Picked up the car from the (non-Landrover) dealer last Friday (i.e. Less than a week ago).

Parking sensors working fine until today.

On starting the car, I get the single long "beep" indicating a fault, and the light on the PDC button flashes three times. Sensors on front and back are inoperable. Pressing the PDC button just makes the light flash three times again. Sensors still don't work.

Have popped the fuse in the boot (in tact), and cleaned all the sensors front and rear. We have had no rain here since I collected the car, so it shouldn't be to do with damp/rain.

My understanding is that a Landrover service centre will be able to diagnose the exact location of the fault in minutes using their IDS?

My intention is to book a slot with a Landrover service centre to do just that. i.e. Plug in, let the system do its magic, and them tell me which bit has gone wrong there and then? Is this realistic/accurate?

I then intend to take it up with the supplying dealer. They "bundled" a 6 month warranty with the car.....fine print seems to exclude "sensors", so I guess it will depend on what has gone wrong (hence my trip to the Landrover dealer in the first instance, so as to arm myself with information).

Thoughts, suggestions, advice, general criticism gratefully received!!!

Bloody warranties they ought to be named and shamed. Maybe try disconnecting the battery to reset the car? When I die, I want to go peacefully like my Grandfather did, in his sleep -- not screaming, like the passengers in his car

Haven't tried that.

Anything I should know before I disconnect the battery? Does the Freelander have a radio code (or similar) that I need to ensure I have before I cut the power?

Dealers normally have a gun, that detects the signal a sensor omits, that might ID the faulty sensor

But a faulty sensor doesn't normally cause the dash button to flash, so might try a guess at the wiring loom or module is at fault, so your Warrenty might work, if not push for the dealer to fix Former Mod/Member, with the most post & Chicken George Arch nemesis

No radio code, just disconnect both terminals, touch them together, go indoors, have a cup of tea then reconnect, all you will need to do is a window reset, it's in the manual  p****d off with a Digital Keyboard Warrior

Just to add to the above posts, if it is indeed a faulty sensor that has caused the shutdown

Quote:

The parking aid module performs self check routines and when the system is active checks the sensor wiring for short or open circuits. If a fault is detected a code is stored in a memory in the module and if necessary either the front and/or rear sensors can be disabled

Thanks all.

In dialogue (via email - I wanted it in writing) with the supplying dealer about the best approach.

To their credit, their initial response was "give me a call, and we'll get it in and get it sorted for you".

My only concern is that:-

a) they are a 70 mile round trip for me
b) they are not a Landrover dealer - their level of diagnostic expertise with this fault is (through no fault of their own) not going to be as good as a proper Landrover dealer.

I would prefer to get it hooked up to the IDS at my local LR dealer so as to know exactly what we're dealing with. On the other hand, I don't really want to fork out cash to get this resolved......

Fun and games....

I think the supplying dealer has been fair in offering to sort it out for you. It may well be that they have an arrangement with a specialist who has the diagnostic equipment. If you take it to a Land Rover dealer then it won't be cheap. Andyfr

The hook up to the main dealer diagnostics will probably cost you a £100 "free" cup of coffee ! - 2007(57) XS Auto, Rimini Red, Alpaca Leather.

Agreed.

Was pleasantly surprised by the reaction of the dealer.

However, don't really want to faff about with a 70 mile round trip, twice.


Investigating what a hook up to the IDS will actually cost. Do you think if I take my OWN coffee, it'll be cheaper?

Well - on the advice of the local LR dealer (who can't see the car until next week), I selected reverse, disengaged the handbrake, and gently touched each sensor.

Apparently there should be a "pulsing" or "vibration" from each working sensor.

I didn't detect ANY pulsing or vibration from ANY of the sensors.

In my book, this suggests either the module is at fault, or the wiring loom?

Is my logic correct?

Incidentally, where is the parking sensor module located?

Nice one from the dealer...
You wont be able to sense the ultrasonics.
There are very low power ultrasonics and they are .... ultrasonics...

The parking module is in the boot, behind the LH rear quarter trim panel.

Oh dear I hope that was not one of the workshop guys that gave you that advice, as said there is nothing to hear or feel

Just repeating what the two different LR dealers said to me, guys. Sorry.

They both said you can hear a "click" if they are working correctly, and they both said if you gently rest your finger on the sensor you should feel a "pulse".


So.....from your replies, the fact that I didn't hear a pulse/click from any of the sensors doesn't necessarily mean they're not working (or that they are).

In other words, I am no further forward.

Just a quick update to this to help any future "searchers".....

Spoke to Phil at Chichester 4x4, a local independent Land Rover specialist.

He offered for me to pop in on the way home from work, and to connect his diagnostic equipment to my car.

In 5 minutes, whilst showing me how it all worked, he'd diagnosed a faulty rear offside sensor.

All for a few beer tokens. Less than a fifth of the cost of a LR dealer!!!

So.....off onto eBay now for a replacement sensor.

Thanks to all for all your help and suggestions.
