alarm module location

[Dazzler101]

Hi
Just had complete electrical front end failure on my 2006 C8 so I have replaced everything except the alarm module because I cant find it!. Could anyone tell me where it is located on the car, it would really make my day

The Siren is in the front right wing.
The ECU is in the interior of the car somewhere on the engine Bulkhead.
And then there are the various sensors dotted about.

Just finished putting the front interior back together after stripping it back to the bulkhead, no sign of the module. Anywhere else it might be?. It's a 2.0 16v petrol if that makes a difference

From memory is clipped to the bulkhead up behind the glovebox, small black box with blue & brown connectors on it & a label that says TEXTON.

This one sitting on my shelf but you need to know the correct part number I think.

The label on this says Texton Module Alarme 965500780

Yours free if it's any good for you.

Thanks for the offer I already have a replacement. I have stripped the facia completely back to the bulkhead leaving only the heater matrix and blower but it is nowhere to be seen. Is there anywhere else that it might be ie over rear wheel arch 'cos it ain't on the front

I know this is a bit late, but can you pop your VIN up - just in case it isn't fitted with one!

I've had a look at another Petrol C8 of this year and there is a unit called the interior protection unit (anti-theft alarm) - item is 8602 on this diagram - which if it's what you are looking for would appear to be here:

VIN VF7**************[VIN obfuscated, can be read by forum staff],
when I bought the replacement parts they sent me ecu, bsi ,key transponder, speedo module and alarm module. I fitted ecu bsi and key transponder but not clocks or alarm module as I did'nt think that these would be coded to ecu, but when I connect the battery and do the reboot the engine turns over (which is an improvement on before) but will not start and the alarm is activated but not the siren just the hazards on continuously even with the ignition off, I have to disconnect the battery to switch them off. I dont want to throw the car away as it really suits our needs but I am getting towards the end of my patience

Right, that answers the first issue - the vehicle was not fitted with an anti theft alarm at the factory, so that's why it is not there.

Second, if you have replaced the BSI and engine ECU and the BSI was lifted straight of another vehicle, it will be configured with the options for the donor vehicle. So if your donor BSI was from a vehicle with an alarm system fitted, then the ECU will be configured as present in the donor BSI, when it is not physically installed in the vehicle. This will be one reason why it is playing up.

What you need to do is go through the BSI settings / configuration and make sure you have the correct equipment fitted for your own vehicle. Obviously, one thing you need to do is locate the Alarm section and change the option to non fitted.

So, using Lexia:
"DIAGNOSIS"

Select the vehicle
"GLOBAL TEST"
"BSI ECU"
"PROGRAMMING"
"MANUAL CONFIGURATION"

Choose the following sub-menu:
"CONFIGURATION"

The sub-menu "CONFIGURATION" has 5 sub-menus:

"VEHICLE DEFINITION - EQUIPMENT - DRIVER’S INFORMATION"
"AIR CONDITIONING - CABIN HEATING"
"LIGHTING - SIGNALLING - VISIBILITY - REAR VIEW MIRRORS"
"LOCKING - DOORS & TAILGATE - IMMOBILISER - ALARM"
"FUEL GAUGE LAW - OIL LEVEL GAUGE LAW"

So first of all locate the Alarm section and change it to 'not present' or whatever the option is.

You may have to go through the BSI (caution advised) and just look for anything obviously not correct. Your engine is an EW10A and the injection system is a Siemens (SID803) from what I can tell. Make sure the correct gearbox is selected (BVM5) too.

If you need a hand - post back after you've digested this.

[wheeler]

Siemens SID803 is a Diesel injection system?

[GiveMeABreak]

That's what the VIN states as the injection variant - but I'd expect it to be a Magneti Marelli or a Bosch - so look out for MM6LP, MM6LPB, or MM6LPC, but whatever it is, when you do a Global Test, look under the Engine ECU Icon and it should provide you with the engine ECU identification when it picks it up.

[Dazzler101]

Thanks all for your help, seems like I am moving forward on this now. ECU is indeed Magnetti Marelli 6LPB so next.......
Have laptop, no lexia, there seems to be a lot available out there but have learnt from experience that they dont all do what they say on the tin, can anyone recommend a system that will do what I want it to do

The equipment supplied by Easy Diagnostics is considered to be pretty good.
