When parking 4 days ago, I reversed quickly (ish) out to readjust it and drive back in, when there was a really bad smell and some smoke from the hood for 20/30 seconds. Now when I drive it, its fine 99% of the time, no gear slippage etc, but when I stop the car it makes a clunking/banging sound every second or so, and sometimes smells outside like burning.

Is it my clutch, or could there be another issue? I’m a complete car noob. Thanks all
