Seat leon 2009 1.6L 5 speed manual

I am a newbie when it comes to seat cars, I bought the car last week which seemed fine to me at first, then I noticed that when I drive for like half an hour and the car is properly warmed up, the idling gets rough, engine starts shaking and the rpm goes up and down a little on its own, also I get the traction control light on the dash, and the car gets harder to drive, sometimes the car shuts down when in traffic on its own, and it takes like 3 tries to turn back on, I leave the car off to cool down, the car starts normally, worth noting that I have right headlight not working nor the right fog light, as well as the left tail light, traction control button not working, nor the right passenger side window or the central look buttons, car only locks with the remote and doesnt open with it any help would be greatly appreciated and sorry for the long post

Hmmm sound like the coil packs to me had a similar issue with my fiat stilo back in the day, change the coil packs and it ran like a dream... I mean until the starter motor died lol

Thank your for your reply, it could possibly be coil packs, I read somewhere that it might be coolant temperature sensor as well, is that a possibility?

Yea also a possibility, shouldn't be too expensive to change either of them so maybe do both and see what happens?

Get it scanned for diagnostic codes, you're just guessing otherwise.

If your going to do that then get a carista I did and got a non pay version of the app and it was so worth it plus the cost is going to be alot better

or VCDS, loads more functionality than Carista.

Turned out i had faulty crankshaft sensor, as well as throttle position sensor, i changed the crankshaft sensor, the car stopped stalling, but still needs to change throttle body
