My 2010 focus titanium throwing a real wobbler? Sometimes hard to get key fob to work. Have changed battery: when you get in sometimes the keyless start is dead. Keep trying eventually it works. When running. Radio cutting in out on sound. Air con blowing only warm. Immobiliser light pulsing. Some times just one flash then two sometimes three. Same flashes same as radio sound glitching. Also front fog lights flash in time with above. Had battery checked and alternator and reset the earth from negative on battery to earth point on inner wing. There is a relay in box under bonnet constantly clicking? 
Any ideas please????

Thanks

Forgot. Sometimes chimes and says no key detected then clears on its own while driving?

Forgot to include another symptom

Has it got passive entry too (not only remote but buttons on the door handles too)?

Yes. Push button on door handle! That hasn’t worked occasionally and I’ve gained entry using key.

There is a separate RKE module in the passenger rear 1/4 panel (somewhere) suspect this is filled with condensation and not functioning. Same faults as on my Father-in law's Focus, same spec, his was the RKE. It's not the GEM

Get it sorted ASAP as he had the steering column lock come on on his, luckily he was only doing very low crawling speed at the time

Worthwhile not excluding the common issues of the mk2/mk2.5 Focus. Instrument cluster solder and BCM/Fusebox corrosion?

Dtcs through the obd (Forscan ) may help diagnose.

Had that done previously thanks.

also now draining battery over night!!!!

Thank you
