I’ve been looking online and have found a company in Poland offering for sale what is claimed to be a remote controlled device to manipulate the tachograph. I’ve come across the type where a second sender is hidden away and switched remotely and I can sort of get my head around how those work although I can’t work out how it wouldn’t show a sender disconnect fault when switching between senders. The ones on the polish site claim to be undetectable and wireless installation, has anyone come across this type before?
I have no intention of purchasing one it’s just purely an interest from a technical point of view, as I can’t see how it’s possible.

It genuinely is an interest from a technical point of view. I’m lucky if I do 10 days of actual driving per month so I’ve no need to do any proper naughty stuff but I am interested how these things work.

they work…apparantly…if a human makes it,another human can break it…who could condone such an act of criminality though…on the bright side,it save you trying to wrap up 3 feet of wire and crockodile clips down your pants while crashing to a halt behind the vosa van…all in the name of road saftey and saving the children.

I too have no intention of getting involved with these things, just to get that straight.
Imagine someone buys one, fits it, and then gets caught. If it is detectable after all, are they going to the Police to make a claim about false advertising? Like to see them in court asking for a refund !
UNDETECTABLE tell that to the EU drivers that have been caught,the Authorities here have the gear to detect dodgey tacho`s, undetectable is a load of BS
If it sounds to good to be true…

It could well be an advert from a Firm of Accountants who`ll get all your taxes refunded from the last 20years, honest.
Getting caught in the Basque region of Spain with that, say goodbye to the lorry in the compound, and pay 30,000 Euros on the roadside .
Devices have been used for a while to set the tacho to bed while driving.
You see lorries parked in the Dvsa checkpoint at Stafford for a few days on enforced add on rest period with their wheel clamped .
As said Dvsa can detect fraudulent equipment.
The days of one hits to southern Europe are long gone at four days driving with no rest at all .
Crocodile clips and pulling fuses on analogue tachos ,extinct like the Woolly Mammoth and the dinosaurs .
You’d get less hassle by not keeping records r,at her than making a false record
This is an interesting debate. 
I’m no technician, but I’ve come up with two theories…
Theory #1
If there’s a gizmo that sends a signal to another gizmo to disable it, hasn’t the second gizmo detected something that’s said to be undetectable?
If I’ve got this right, then the maker of the first gizmo is claiming that their device doesn’t work.
Theory #2
IF theory #1 is incorrect and the first gizmo can actually send a signal to disable the second gizmo successfully, then a DVSA officer can also detect that signal with a gizmo.
I think “undetectable” just means that there are no wires or crocodile clips and that somebody has come up with an electronic version of an old and very detectable dodge.
As I said, I’m no technician, but I can see an interesting discussion between DVSA and Trading Standards brewing.
They probably send you a little empty black box that does sod all but what are you going to do when you realise you’ve been conned? “Excuse me officer but this device I bought to knowingly break the law doesn’t seem to work!”
It probably comes with a free CD to hang in the windscreen as they make you invisible as well.

Clear overview and explanation of how they work. From Euro Police site. They say they are sophisticated and difficult to detect, but clearly the authorities won`t be in the dark about all of this.!”
EDIT, love coppers with a sense of humour, they`re human too.
“The passenger stated that the police in Germany said the tachograph needed to be repaired. He stated that the tachograph was broken. I asked both men to take a look at me again… Do you see a big red nose■■? Do you see huge long shoes■■? The answer in both cases was: “No.” I shared my conclusion with both men: “That means I’m not Bozo The Clown”
SwedishBlue’s post on the subject shows these remotely controlled devices.
Their was a video going about a while a go with a DVSA officer stating that a tacho head unit only draws 10mA of power so if they suspect foul play they put a multimeter on it & if its drawing more then their is some sort of tamper switch/device being used & they will if they have to to strip the whole dash out to find it
And of course one of the best ways of detecting these devices is when a driver trying to impress shouts his mouth off in a cafe or in the boat or a disgruntled drivers leaves and spills the beans to someone authority, As I assume happened to a haulier round here many years ago who was known to run dodgy, when his truck got stop in France and the Gendarme went straight to the hidden switch.
there are so many ways the dvsa can detect if drivers are on the fiddle and they dont need too strip anything.
Maybe its the same company who offer to take a test for any vehicle, and issue you with a pass certificate, which you send off to our own DVLA to add to the licences you possibly may have, i believe they give away a free set of handcuffs too…all of this for £250…beats a getting a genuine class1 licence for driving a farm tractor with a trailer behind i suppose.

the easiest way for them to do that is to take a quick look at your number plate…if its irish,north or south,and your not one f the few that run legal,then your detected…
