Booked in my Car as a rattling noise started up when I started the car. Halfords advised they could fix the problem and replaced a 'pipe' costing me £150. I left the garage and the noise started up again. I took it back to Halfords who told me they did not have access to look inside the engine to find the still rattling noise. So I took to another garage and found the rattling noise was that it needed a new timing chain fitted. Pretty standard to replace at most mechanics!! So I am unsure what I actually paid Halfords Autocentre to replace for £150. Money grabbers!!!
