Yes — this is standard across the industry for any remap. It can be reversed and returned to standard at any time.

Not if the underlying cause is fixed. If it isn't diagnosed and resolved, it will block again. Common causes include frequent short trips with no motorway driving, boost leaks, faulty injectors, and poor service history.

Warning signs include an oil pressure warning light, or — on Transits and 2.0-litre models — a noticeably hard brake pedal, which can mean belt debris has reached the vacuum pump. If either appears, don't drive or start the car — call us straight away.

It depends heavily on service history and oil change intervals (ideally every 8,000 miles on 1.2 engines, 10,000 on 2.0). We've seen 1.2 belts fail as early as 35,000 miles and 2.0s at 45,000, so it's worth having it checked rather than guessing.
