Well after lots of wire tracing and pulling things apart, I gave up and threw it into a local place to have a look. K Motors (LR Direct workshop in Leyland). They cleared the codes, and also took it apart. Cleaned everything up again and so far, the horn hasn't gone off. They gave it a clean...

Rick the Pick is an awesome sounding name, and also sounds like a useful man to know.

Awesome Wazzajnr! I will probably replace the o/s bonnet catch and do some wire tracing. Failing that I feel it is diagnostic time. Holding out a slim hope it isn't new BECM time.

Thats brilliant. Will get back to you when it returns. Many many thanks for your time so far.

There is only one way to find out :D The car is off down south for a week. When it gets back would it be possible to see if your Nanocom can talk to the BECM at least. Will put some monies your way for the privilege. Going by the wiring diagram the only way for the horn to get a live feed is...

Hi Wammers Would you say the cause of my issues is the bonnet locking catch then? As I am driving it is jiggling and setting the horn off. Have to admit I haven't noticed a warning message .. mind I am concentrating more on the fact the horn is blaring for no reason and annoying everyone. Also...

Looks like there is a +12v that feeds the relay on two pins. One goes to the BECM and then on to the steering wheel switches. When you press the button it earths the feed allowing the relay to energise and then supply the feed to the two horns. I am going to assume it goes via the BECM to...

Yup .. two wires fed from the BECM via a fuse and relay apparenty

I am also hoping it isn't the BECM packing up.

As much as I can get to easily. All looks good so far. Was wondering if there was anything obvious I have missed before I start having to rip panels off. Hate electrics.

Hi there. Been searching for a while for answers but nothing definitive. I have a phantom horn issue. Central locking works fine with the key/button. Horn works if you press it. Good (new) battery. Changed the steering wheel coupler. Changed the horn relay. Taken the wheel off and...

Yup .. that sounds right. The lights come on with the ignition. Then once started the handbrake light goes out almost immediately (never use the handbrake, always rest it in park) as the pump kicks in and pressurises the system. Once rolling the other two lights also go out. However oce you get...

Accumulator fitted and brakes are spot on .. just have what looks like a dodgy ABS sensor now. Lights go of immediately on startup. Pump takes 3-4 pedal presses before kicking in. However when getting up to speed the TC light and ABS light come on with a beep.

Yup .. engine off and pump pedal 30 times .. then wait 60 seconds and pump a further 4 times ;) Accumulator on order .. will let you know how I get on.

Cool .. will do that. Cheers.

Yeah .. been reading about it. One of the more simple jobs.

Cheers .. think I will be getting covered in oil :)

Thank you for your prompt reply. I have just had all the disks and pads changed. They also sorted out all the calipers. When the lights go off the pedal is solid. No spongyness at all. So I am thinking that there isn't any air in the system. My gut feeling is the accumulator is failing and...

Hi there Been doing lots of reading and cross referencing and I think I know the answer, but would like to confirm. ABS and Traction control light will always stay on a while after start up (30+ secs or so). I can hear a pump going for it from under the hood (could be either the suspension or...

Well it has been a couple of weeks and a couple of thousand miles and fingers crossed all is well. Thank you for your advice on the matter.
