P053F: Fuel pressure too low during a cold start on direct-injection petrol engines. Hard or long cranking when cold.

Engine and gearbox (powertrain) · Costly if missed

Usual causes, most likely first

weak in-tank pump or blocked filter
rail pressure sensor (G247) or wiring
fuel pressure regulator valve (N276)
engine timing out (check if P0016 is also stored)

Before you clear it

Write the code down or photograph the scanner first. A code that comes straight back after clearing points to a fault that is still there. A car whose codes were cleared just before you arrived may be hiding one: the scanner's readiness monitors show "not ready" for a while after codes are cleared.

Researched by Credov from manufacturer and workshop sources. A fault code points to where a fault may be; a workshop confirms it with a diagnosis. Browse all fault codes.
