My car seems to be playing up on starting recently. Sometimes it starts fine, although it does initially 'Humm' louder (stays on a higher amount of revs before settleing down to below 1) for the first few seconds since the engine was steam cleaned 6 months ago.

however, there have been 4 instances in the past week where i have had to keep the key turned for around 5-10 seconds before the car starts. The car is cranking during this time and my foot has to be flatdown for the engine to eventually turn on. The EPC light also comes on and stays on too somtimes

i have a video link below. please note the banging noise is actually me pressing the accelerator hard a few times

any advice will be welcomed
