Following on from this thread, I am afraid that I have been advised legally not to divulge this information. So please do not send me any more requests for it as I cant divulge it sorry. I fully appreciate that the vast majority of enquiries would be from legitimate owners seeking help with their car. However, I still cannot give out the information. Sorry.

If you are stuck with your immobiliser then I strongly urge you to use the mobilo life services.

Despite me being very clear on this issue I am STILL getting people emailing me asking for the fix.

So lets make it even more clear.

Hi Alfie, I noticed you have posted several posts to try and stop people emailing you the same question. I need to say that I keep receiving emails asking me if I need Viagra however I've found that IGNORING THEM is far more effective than replying to them.


Hope this information helps.

Mr Limp.

I see the point but those who email in are potential customers which is different to those sending in invitations for 'other' things. Besides Messagelabs does a 1st class job at filtering them out anyway.

Every customer or potential customer deserves a reply. I would just rather they didnt waste their time asking and me having to politely decline.

I think its damn right disrespectfull that members cant abide by the fact that you dont want to give out how to disable immobiliser.
You contribute greatly on here and to harass you and maybe scare you off from this forum is not good.
god is my chauffer, so can you tell me how to do it??? lol

high luke, where are you located? i have done many many of these, assuming you have the dealer fitted immobiliser. do you have silver stickers in the windows saying 'fitted with an approved mercedes benz alarm system'??

this immobiliser was dealer fitted, not factory fitted, and certainly needs removing. you will find the control unit in the passenger footwell behind the steel plate. look for the yellow/red black/purple wires and trace them to where they intersect the original wiring. simply remake the original circuits and trace all the other wiring and remove as necessary.

Way to go mine looks more yellow/orange and black/purple all sorted now here have a look.

you are welcome, but it is yellow red...

I had cause many years ago to call upon Mobilo to get my car (W202 C180) going after the immobiliser refused to let go of my car. The car unlocked and locked fine but inserting the key and turning did nothing.

When the chap from mobilo came out he quickly disabled the immobiliser which shocked me when I saw how simple it was. It takes about 5 minutes thats all.

I'll PM you the solution.

EDIT: Cant send you a PM as they are not enabled for you. Send me an email to sales@comand.co.uk and i'll reply with the solution.

I too am desperate to know how to bypass the immobiliser on a c180. The alarm system is failing and I want to turn it off. Any chance you could send me the solution.

Thanks

Welcome to the forum, but see post no. 45.

Thank God, the car having done sterling service end last week getting me back from France via Dover before it started to play up yesterday. Could not get system to re-set after renewing batteries in fob. Did try a alternative fob which I am now thinking had a different number on it., was this wise? Same key to car entry.

Anyway resolved to disable but this is the gubbins that has greeted me when I pulled back the plate. No obvious Alarm box (silver sticker in window) to remove plug and splice two cables. Looks like it has been butchered previously. Certainly no alarm has ever gone off, just the indicators flashing, pausing flashing.

Any clues how to proceed? Oh I did just disable the battery and re try setting the system but just got the flashing lights in the mirror and the humming sound of the fan.

Nightmare begins.

What year is the car?
What kind of key fob/s do you have?
What is writen on the Silver sticker?

Is a 96 S Class 320. Thought I would see the same as the E class 320 behind the plate but not so.

Keyfob is as per example in photographs from Dec (thread 22) .

Some good news, having seen what looked like a different system I reconnected the battery and did manage to get the system to reset and the car to start. Still not happy I don't know how to disable the immobiliser as I'd have been stranded in France if it had gone awol last week with no computer. Probably the fob batteries were the problem as volt 3.12 reading and new ones 3.32. Nevertheless, if anyone can tell me if the Alarm box is in the photo I would like to know. There is (difficult to see) what looks like a four part connector without a box. Many wires to this unit.
The other cables at the front right I am assuming relate to either the Car phone /Loudspeaker/ Antenna, or the ex-radio and remote. There are no cables in the bunch the colours I am looking for.

If your alternative fob is now also working then it is likely that the siren is the cause of the trouble, to test the alarm, try locking yourself in the car and stay still for 30 seconds then open a door to see if the siren sounds.

Some of these sirens have backup batteries which can die/leak and destroy the circuit board inside the siren, replacing the siren could solve the fault.

What is written on the Silver sticker?

Expected it all to look like photo in thread 50 but no.
The siren has never sounded and I could try your suggestion, but apprehensive that once sounding I won't get it to switch off, so will pass. Is the siren located in the engine bay?
Still need to understand why is there no obvoius box? Could it be put elsewhere on my car - boot perhaps or ??

 

[Dec]

Now that the car is starting do you have any means of turning the alarm off… have you an extra round/odd type key perhaps?

There are many different alarms fitted and many ways that the can be wired up and so there are different ways to bypass the immobiliser, so, on your particular car, without the advice of someone who had done it then its difficult to proceed any further.

The way I see it, you have to determine if the alarm is working properly or if it is faulty and is the cause of this fault, for example, when you reconnect a car battery, the alarm will re-arm itself and immobilise the car and because the boot or bonnet is open, it will be triggered, pressing the key fob should then disarm the alarm… what I’m getting at here is that if thee was an intermittent fault in the siren the alarm could keep re-arming itself, so, its important to know what the indicators are doing when you lock or unlock the car.

Normally when you lock the car the indicators should flash 2 or 3 times to indicate that the alarm has armed itself and when you unlock the indicators should flash once, so, if the indicators are flashing for much longer than 2 or 3 flashes then the alarm has been triggered and if the siren is working properly, then it should be sounding.

For the time being, don’t lock the car with the key fob button, that way the immobiliser will remain disabled so you will be able to start the car but you will have no security and you will have to lock the car via the door locks with the key blade only.

I can’t see anything in your picture that looks like an alarm “brain”, in the case of my car, the alarm brain is located under dash as in attachment… http://forums.mercedesclub.org.uk/attachment.php?attachmentid=12803&d=1284900436

Your siren might/should be in engine bay, high up so as to be free of heat/water splashing.
