Urgent help needed ... :( information required

Got a Cupra Tdi ..... Did 240 miles and then parked it up for a week

Fired it up occasionally but today took it for a drive and got the following

- Flashing Glow plug (coil) light .....
- when I did buy the car I noticed there was a rear passages side light which wasn't working but nothing came on then ???

Plus the TCS light was on but it's gone now

Please can someone help ?
