Really helpful - thank you so much. I'm a real novice with cars, so I don't think I'll disassemble parts myself. Will likely take to a mechanic, and your guidance means I can guide them to the right fix. Really appreciate your time!
Hey all - my 2015 vauxhall corsa is making a screeching sound as I'm turning it on (sounds a bit like a lawnmower) and having to try and turn it on multiple times before it starts. Its got around 75k on the clock I think and 1.4l. Battery and alternator are supposedly fine (went to Halfords)...
