Why does the alarm on my 2011 Ford Fiesta keep going off?

I just bought a used 2011 Ford Fiesta. I'm used to regular keys and keyfobs for the locks, but this has keyless entry/ignition.

I just got this car home and locked it before going into my house, and 3 times now I've heard the alarm go off, and when I go out to see what's going on the lights are still flashing and the alarm is getting quieter (if not totally silent) (and the lights are still flashing).

I've been hitting the unlock/lock buttons on my keyfob to make it stop but I still don't know why the alarms are going off in the first place.

OBD 2 Software (Ford UK Vehicle)?

I'm looking for some free (or cheap) OBD software to analyse a potential issue on a Fiesta 1.5TDCi

I have a cable - so it's only the software I need. Just one thing, NOT SOME WORTHLESS DEMO.

Windows or Mac - either will do.

Could anyone post a link to a suitable site?

How much would it cost to insure a car?

I'm thinking about getting a 1998 ford fiesta from gumtree its £400 for the car and I'm 19 years old and I'm wondering how much would it cost to insure it

What's wrong with my car? Clunking at front left side. Could it be my brakes?

I have a ford fiesta zetec. Like an idiot I did not run it for a few months after getting a flat tyre. I had the tyre replaced today and used my cover with green flag to get a guy out to recharge my battery as it was completely flat.

The bloke who changed the tyre said the brake stuck but had released when he changed the tyre. (right drivers side)

However when I set off in the car earlier I noticed a clunking sound from the front left side (sort of with each rotation) and so I went straight back and parked it. I could feel the brake pedal moving as I hovered my foot in time with the clunks.

Is it likely to be a rusted brake?

Advice would be great!

Can anyone advice me on my car trouble?

I hope someone can advised me on what the issue could possibly be.
I have a Ford Fiesta LX MK6 1.4 (2004), every day when i turn the ignition the car starts up and immediately stalls, and this keeps happening every time I try it, if I hold my foot on the accelerator slightly and turn the ignition the car will start up fine but as soon as I take my foot off the car will stall again, but if I hold my foot on the accelerator long enough until the engine has warmed up slightly I can then take my foot off and the car will be fine and stay on, I can even turn the engine off and start it up again with no problems, if the car is then left long enough for the engine to cool down over a few hours and then start the engine the problems repeats itself.

I have linked a video i recorded of my car doing this to give you a better understanding.

hope someone can advise me on the issue so i can an idea of where to start before i take it to a garage.
