    Call to action!! Anybody who has/had door lock sensor problems

    following on from my post
    headed 'explain this' I spoke to someone from Cherry UK, the door latch micro-sensor manufacturers. What she said was that basically the more people who complain, the more Cherry, and in turn Audi Germany will listen. As far as they are concerned at present there is NO problem!!!

    So what I am asking is, who is willing to send emails to Cherry detailing door lock sensor problems you have had/have? The messsages will in turn be forwarded on to Cherry Germany (where the switches are made) - if enough of us shout loud enough they will have listen!

    Come on people - lets use the forum to give us some clout!

    I'll mail - perhaps set up a standard letter which we could all download or copy and paste?

    Just to confirm - it is the switch at fault and not some other associated reason - such as the design of the housing or mechanism within which it is installed?

    After tearing the whole thing down and watching it work with the door card off, that it is the micro switch at fault. Several Audi dealers have also confirmed it as being a problem.

    And yes, standard letter is the way to go!

    I've posted on the A4 and A6 forums as well, as they use the same switch.

    Audi is well aware of the problem through warranty claims.

    every switch that plays up under warranty, means a whole lock mechanism is replaced.

    someone, aka Audi foot the bill for that, and the labour to fit it.

    but if you're just out of warranty then YOU have to pay - and if you're not competent to do it yourself you're looking at labour charges as well. This is not a complex part and not something that should be failing this regularly - not good enough on an Audi.

    give me the mail address and I'll mail - template would be good, I'll also send them the whole faulty latch so they can see how audi are using it if it'll help!

    Hold fire!

    I've had an email from Cherry Germany's Senior Quality Control Manager!!!

    It was just an acknowledgement email but he has promised answers tomoro

    I'll keep you all posted on what he says and where we go from there.

    Thanks everyone for the support so far.

    Re: Call to action!! Anybody who has/had door lock sensor problems

    i guess the one in the tailgate is the same too? I dont have a DIS to tell me, but i have noticed the bootlights staying on sometimes if i looked through the gap for the fake speaker next to the parcel shelf.

    count me in too, had my drivers side replaced under warranty fortunately for me, but it sucks if u gotta pay out of your own pocket for a design/quality fault.

    Re: Call to action!! Anybody who has/had door lock sensor problems

    After severals emails between myself and Cherry's Senior QA person, he has concluded that it is not the switches at fault..... Their conclusion is (after talking to the lock manufacturer, who they sell the switches to, and who then in turn supply Audi) is that it is the interface causing the problems i.e. what the switch sends the signal to.

    I find this odd seeing as a new latch always sorts out the problem.

    So I am wondering is it due to fluctuating voltages in the car etc etc - who knows?

    So really no further along than before...........

    I'm going to try a multi-meter at various points in the circuit to check what's going on. What I would also be interested in, is to see a diagnostic result on the problem - does it just say 'faulty latch/sensor' or will it reveal more??? So, anyone with access to VAG-COM etc, see if you can get a diagnostic done!

    well, if it is the switch then it is never going to register a fault as the car will just interpret the signal as the door is open. Is the switch a proper micro switch or cheap domed metal 'cap' style?

    Re: Call to action!! Anybody who has/had door lock sensor problems

    I have found that it is not really a manufacture fault or Audi fault, it's due too people spraying lubricating Grease into the mechanism which atract the dust which in time gums up the workings.
    i have found that by spraying with carb cleaner or brake cleaner and opening and closing the door several times that this cures the fault until the build up of dirt returns. Hope this is of help

    this (crap) pic has the microswitch at the top. You can see the connector and the white actual switch part.

    I have never sprayed any grease or lube into my door locks, how do you explain mine failing at only 20K?

    Re: Call to action!! Anybody who has/had door lock sensor problems

    but has anybody actually had a diagnostic done to see what it does say??? perhaps it will just come back with door open or duff switch/latch, however it's worth a try.

    I would want to do a diagnostic when the interior light is flashing - surely this would reveal more.....?

    I'm in as well [img]/ubbthreads/images/graemlins/grin.gif[/img], this has happened to me on both my cars, my previous 1.8SE and it's happened once or twice in my S3, will keep a look out on what happens here.

    Re: Call to action!! Anybody who has/had door lock sensor problems

    Is it just on the latch that they go? As there are what look to be micro switches on my old door handles and locks?

    Also what does this mircro switch do? As my car no longer has the door locks.

    there could be micro switches for the heated locks too.

    I have the answer why!

    At last I can tell you why the switches are failling.

    When the switch was initially designed (in '94) and then mass produced in '96, it was designed to work at a certain current/voltage load - in the meantime (Cherry are unsure when) the load was increased which feeds the latch switch (either by Audi or by the door latch manufacturer). The switches were never intended to work in conjuction with the increased load, and even though they do work, reliability is decreased. The increased load causes them to gradually fail. Audi have since found out about this and on newer models (presumebly the new A3 etc) the switch was changed to cope with the increased load - hence no problems.

    So there you go - it isn't Cherry's fault, it's ultimately the fault of Audi. And quite simply we're all stuck with problem for as long as we own 8LO and 8LP A3's.

    Re: I have the answer why!

    So is it possible to use a switch from a new A3 onto the locking mechanism of the 8L A3?
