Citroen DS3 Problems

When opening car with key fob ok. When locked with key fob sets alarm off few minutes later. Locked manually is OK. Why is this?

Acceleration down, top end down, struggling on hills, started after cold weather

Not starting first time ,once it start goes well ,some days she takes 7 attempts change battery, and starter motor, still not starting

When turn engine off, headlights start flashing and wipers start going (they are turned off)

The display screen does not come on immediately, can’t use heaters, radio, and reverse parking sensor etc

I've only had the car a couple of days but the time and date flashes constantly. I reset it and as soon as I turn the engine off and restart it does the same again. Also when flicking through the menu...

Warning to stop, engine temperature fault temperature went to red and fan came on

The esp /abs light and steering warning light is on got a fault code 0047 and d321h/54049 any ideas

Passenger side front and rear footwell is wet and going mouldy… strong smell too. Could this be any drain hole blocked. If so where would they be? Thanks

Had mot and new sensor replaced, the garage said the sensor is still showing that that sensor is at fault but also showing it has been replaced?

When using Apple CarPlay the audio from the phone will skip or stutter anywhere between every minute and every 5 minutes - any ideas?

Wipers won't turn off even with key out of ignition, the only way to turn them off is by pulling the fuse out when they are in park position. After i put the fuse back in they will stayed turned off ...
