car immobiliser wont turn off. is it the remote???

[Shala]

today @ 5.30 i got something from the car boot using the remote control to open boot. after work @ 8pm & went to open the car using the remote. if i press unlock button the indicators flash but the door doesnt open or immobiliser doesnt turn off. I opened the car door manually with key & alarm went off. normally if I put the key into ignition the alarm will be disabled but it didnt today :crazy:

any idea what i need to do??????


(background.. the windows hav stopped working randomly for last year or so so i had to disconnect the battery to reset the faults)

any help welcome as cars still sitting outside work & need to pick it up soon.

To me it looks like moisture in the passenger compartment CAN door control unit.

I can send you the papers and see if it fits what you have.

it fits with the rain we are having

PM me your Email address

[Shala]

the remote still operates the auto-windows & i managed to drive the car back with the alarm still blairing.

the rear interior light cant be turned off.
the boot cannot opened using the boot release switch
the alarm doesnt turn off
the central locking doesnt open or close from the interior switch or the remote.

I hope the paper fits the Bill , not an easy fast fix.

As the remote locking is involved I have left out the PSE faults for the minute

[Shala]

PSE??? whats that? sorry

[Shala]

i did manage to disconnect the wire for the rear interior light. or that would've been another dead battery

[television]

PSE??? whats that? sorry

Thats the pump that unlocks all of the doors and boot

[Shala]

i always see water on the rear passanger kickplates. does that add to cause of the fault?

[television]

I first saw that you had window problems earlier that could be rectified by a power down. the paper list all of the faults that could happen, it does not mean that they all have to be there.

Water in the doors is the reason to change the things on the list. powering down and dring the components with a hot air gun would verify the fault, if you can get through this rainy patch this would also prove it

[Shala]

do i have to buy a control unit as a final resort? so the front control unit is fine then? and its the rear control unit thats causing the front one to haywire right? so if I dry the rear control unit then it'll solve the problem.

[television]

do i have to buy a control unit as a final resort? so the front control unit is fine then? and its the rear control unit that's causing the front one to haywire right? so if I dry the rear control unit then it'll solve the problem.

I do feel that the items on the list should first be dried off with a warm air gun first, then a power down and up.
If this is the problem maybe there is a way to seal them better, baring in mind that you do not want a situation where moisture can get in but not out.

As this is a CAN fault it should be possible to get a fault read out on STAR with an indie

[Shala]

how would i open the boot? I cant open with the remote or inside switch. or cant use the boot lock as its got different key & I dont have key for that :(

[television]

So it has taken the PSE pump locking as well. Are you sure it is the wrong key for the boot ? they are quite stiff to turn.

It may be necessary to disconnect the offending door controllers, I will post back

[Shala]

hold on... i'll go try

[Shala]

nope. the key goes in 25% and thats it :(

[Shala]

is there any other way of opening the boot??

[television]

The Can bus is being pulled down. I do not know if this will work but if the fuses are removed from the offending modules that may enable the PSE pump to run. I can have a further look a little later in the day

[Shala]

i apreciate your help Malcolm. I know the faults usually reset if the battery is unplugged. i dont wanna open the front doorcard while cars live as I think the airbags may go off or I would've disconnected the door control module to see if this resets the fauts & gets it working.

[Shala]

And I await your responce as I'm not going anywhere today :(

[Shala]

Hi Malcolm. I found this link on C180 link

http://www.mbclub.co.uk/forums/showthread.php?t=30108&highlight=disable+alarm

it says: "On mine (Facelift model) it's fuse No 7 located in the boot."

so there's no chance of disabling the alarm

[television]

I had to do a few call outs today,, see what else I can find later

[Shala]

cheers :D

[Shala]

spoke to an auto-electrician today on the phone. he said it shounds like its the central locking unit which is in the boot. But I made him aware the problem is getting into the boot. I took the rear seats out to see if I can access the boot but its all metal plated so noaccess

Its the weekend & I really need the car :(

[television]

Can any one else help out here, dampness in the door modules have cut the CAN BUS so that the central locking is not working. could it be the imboliser thats cutting the PSE pump

[Dieselman]

No, the immobiliser can't cut the PSE, but the PSE is diven by CAN so that could be it.

I think the boot key needs more investigation/persuasion.

Can the car be started, this will check the DAS3 and CAN.

The can fault in the door modules stops the imobliser and the pse pump, I was wondering if the pse can be turned on in STAR

If the fuses for the door modeles are removed, will that open the CAN

[stevesey]

In terms of getting into the boot are you sure the lock hasn't seized (wrong key would normally go all the way in, but not turn). It's very common for the locks (boot and door) to seize as they are never used. Penatrating oil, patience and gentle persuasion may help.

[television]

I think that the car will have to go on to Star, an indie is the cheaper option, there are pages of possibles

[Shala]

I got an indie who'll belooking at the car on tuesday. so if it was wrong key it'd still go in? what can I spray into the lock to make it work?

Fuse 7, 8, and 9 are all involved with the central locking, taking them out could perform a power down and up

Just a thought - is it possible to disconnect the battery via the terminal in the box on the right hand side of the bonnet (the one you can use to charge the battery when you can't get into the boot).

OK (never actually been inside mine) but the battery lead must terminate somewhere - hopefully where it can bet easily undone. I'm sure Malcolm will know if it's possble to disconnect at the front (may not help if the rear SAM/fuse box is directly connected to the battery).

Just keep spraying and working the key in and out quite firmly until it goes all the way in, then turn it.

i'm sure the key's went in a bit more. i'll spray again

More WD40 etc and keep pulling the key in and out and rotating both ways (well trying to rotate). Held the blade in a pair of pliers when freeing mine up as you can wiggle back and forth without wearing your thumb out on the little bit of blade they give you to hold onto.

P.S. Did you get the photos?

AA man tried this & broke one my spare keys. then took me to an auto-lockshop who managhed to fix this. Only charged me £25.00 for the hassle (mercedes wanted £100 + vat just to look at the car:eek:). Then I disconnected battery for 1 min & everything started working. At least I didnt have to change the barrell & I have confidence that 1 key can be used on all barrels. On my next day off I'll take of the rear passanger door & give all components a good drying with the wife's hair dryer. It's a Revlon one so should do a good job :D

Thanks everyone for your support on this.

Ouch - they are quite strong he must have given it some whelly (I was thinking more of a rapid back and forth approach rather than simply forcing it until you broke the key).

Glad to hear you are in - don't forget to grease the lock well and check it every 6 months!

Fit a key blanking bung like you have in the driver's or passenger door lock in the boot lock, it will stop the lock getting crudded up again.

I only had 1 on the drivers doon. And I lost it over the weekend while I was trying to access car via key :confused:

How much are they @ mercedes?

[Shala]

I've taken off the rear passanger door. I've been told to dry the unit inside the door & then seal it from anymore moisture. the unit has special screws on it so how do I dry it. Quick answer will be apreciated as the whole doors taken apart now.

Thanks

Shala

[Shala]

here's the unit I can see. how do i dry it? I got a hair dryer

[Dec]

I presume the motor is not working, the most sensible thing to do is leave the motor unconnected and leave the door card detached for the time being, however you must screw the plastic piece with one screw back on at the door lock otherwise the door light pin won’t be pushed in, the courtesy light will stay on and you won’t be able to lock up the car as the alarm will keep going off due to the light being on.

To dry out properly you will need to remove the outer casing of the motor via the 4 torx bolts (as seen on silver part of motor) and leave for a few days to dry naturally. You will need to protect the motor from water that will enter the inner door, the inside of the door is a very wet environment, what with rain dripping past the window seals and car washing.

If you need any further help let us know

Dec

[Shala]

Thanks Dec.

I left the motor unplaugged lasterday morning when panel was taken off. drove yesterday & today & all the other windows are working fine. usually eitehr the front left or right window would stop working the following day.

i did realise that the rar courtesy light remains on so I had to unplug the light itself to save the hassle for now. I noticed the motor is rivitted to the door so I cant take it off.

I'll see which parts I can take off & try & try with the hair dryer.

would you be able to photoshop my pic & dray some circle & instruction on what to take apart? I can take a closer pic of the device if you need me to.

Cheers

Shala

[Dec]

I’m not familiar with your motor, as it is a later version of the one I have pictured however it all works and is set up in much the same way.

Anything that is wet, in an enclosed space, will never dry out until it is exposed to the air.

That “box” area, outlined in Yellow, should open, there is what looks like a bolt at green arrows and possibly others not visible in picture, use a mirror to examine the back of the area. That “box” area should open somehow, either by unclipping or hinging open in some way.

Inside the “box” area there should be some kind of printed circuit board that the plug connector connects on to, don’t try to remove it, it will be connected to “the plastic part” mentioned in the picture, just leave it open to dry or use the hair dryer, you should still leave the parts open for a few days to dry any part the hair dryer didn’t get to.

Next, you must tape the window glass to the top of the door as the glass will drop down when you remove the cover of the motor as described below. An alternative is to wedge the window glass shut with a wood pole cut to size.

Remove the 4 torx bolts at Red arrows, one hidden, you will need a Torx Bit and driver for this job, see picture, pull off the motor cover, you will feel resistance as you pull, like there is a spring inside, this resistance is the magnet inside the motor cover sticking to the Armature. Don’t remove the plastic part, it houses the motor brushes and is connected to whatever is in the “box” area. Don’t twist the armature or try to revolve it in any direction.

Check if there is any water inside the cover or elsewhere to help determine where it got in.

The Window Regulator consists of the Motor and mechanism fixed to the door by 4 rivets. It is possible to detach and remove the motor from the car without removing the mechanism (and the 4 rivets) but that is very tricky, however if you can achieve the above, then that should be sufficient to dry out the unit.

EDIT; There is a second picture relevant to the above which I cant upload because I have just run out of my allocated picture space, if you PM me an email address I can send it to you.
