    Hello, I have the same problem in the e61, namely the remote control works from a distance of about 30-40 cm, when I remove the black plug from the antenna, it does not work.
    Please let me know if you can send the module, best regards

    Did any of you solve the problem with the very small range of the pilots? Which items should be checked? The module has been replaced with another one and everything works, so the problem is in the amplifier itself.

    The easiest way is to send it to me :) I can suggest that the reason may be complex. The simplest failure is the lack of power at the output amplifier. But you've probably already checked that. What remains is the software - the processor or other elements.

    Hello,

    I have a similar problem, the central locking of the remote controls did not work and the antenna had a very poor range, after repairing the cables in the hatch, the antenna range returned to normal but the remotes still do not work, I sent the diversity module for repair turned out to be working. My mechanic sneaks out. Any ideas what else I can do? I have zero knowledge of electronics

    Hello. If it was not sent to me, we can guess about its supposed efficiency. There is a way to exclude a module. However, you have to do it on the car with my telephone help. Get to the module and check if it recognizes the signal from the remote control. best regards

    For me, the CAS module was replaced, plus the old one plus a new key and encoding all PLN 750 cables in the hatch PLN 250. A mechanic in Opole on limestone 1 took over everything in a moment

    Good morning gentlemen.. and ladies if any :)
    I would like to connect to the topic ... both keys stopped working overnight. After digging into the diversity, it turned out that there is no voltage on the third pin. Checked wire behind the hinge.. no break.
    Does anyone know if the lack of voltage on this pin can affect the operation of the remote control?
    I will add that the radio receives without problems

    The voltage on the third pin will appear after turning on the radio - ignition should be about 12v. If you have two remotes or one working. I invite you to repair the module. Mail order or in person Gołdap - Warsaw

    To be honest, I did not check with the ignition on, the radio was also turned off .. so the module ... what are the costs?
    I am from the vicinity of Gdańsk.

    If the radio receives well, there must be power. The repair cost depends on the damage. I do not exceed PLN 250. I repair 90% by mail order, it comes out just as efficiently. One-year warranty for the receipt service 505601317

    I everyone!!.
    I am afraid I have the same problem, with the remotes only. My Fm works perfect, at the moment....
    When I open my module, I can see a dark zone above a SMD component that I can't identify. Could you help me with the datasheet or any information about it?

    Hello everyone on the forum
    From the bottom of my heart I recommend JElo_masta not quite that golden handyman it is also a golden man
    He dealt with my DIVERSITY in 25 minutes together with unscrewing and twisting the spoiler
    Hearty greetings JElo_masta and once again a big thank you.

    I'm certain my aerial connection to the diversity amp is to blame. The one in the glass. No voltage change on 4V line when pressing key on oscilloscope. Key is giving signal using detector. How to make a new aerial? It looks like three pins in that connector. Can I bridge them with a coil of wire? If so, what pins? The purple connector. Thanks.

    I have replaced the diversity amp, repaired wiring, checked all fuses. Don't know if the 'new' amp is faulty. It has been sealed so can't look at it. Seems my old amp has the same black component mentioned above. Can't figure out what it is. The part numbers are different but same frequency. Should it make any difference? Can the key be 'blocked'. Scanner says it identifies as key 2 out of the ten and it's enabled. Snap-on scanner. Thanks.
