EGR flow does not match what the ECU commanded. It is the performance version of P0401 and points at carbon or a cooler fault.
P2413 — also written P2413, P 2413, 2413 — is the OBD-II code for exhaust gas recirculation system performance. Same code, same fix: this page covers every spelling of it.
P2413 is a emissions fault code, typically costing £120–£900 to put right in a UK garage.
What causes P2413?
- Carbon-clogged EGR valve or passages
- Blocked EGR cooler
- Failed EGR temperature sensor
- Sticking EGR bypass flap
How P2413 is fixed
- Clean the EGR valve and inlet passages
- Flush or replace the EGR cooler
- Replace the temperature sensor
P2413 repair cost in the UK
Most P2413 repairs land between £120–£900 including parts and labour. The spread is wide because the cheap fix (a sensor, a hose, a leak) and the expensive fix (a major component) throw the same code — which is why a proper diagnosis before parts are bought saves the most money.
Can you drive with P2413?
Drivable, often with reduced power and more smoke.
Urgency: medium.
What P2413 is telling you
Emissions codes are logged when the ECU's own monitors cannot prove the aftertreatment system is doing its job. The light is the result of a plausibility test failing, not of a part reporting itself broken, which is why the fault is so often in the measuring circuit rather than the component being measured.
On P2413 specifically — exhaust gas recirculation system performance — the stored code records the moment that check failed, not the moment the part gave up. That gap is why two cars with the same code can need completely different repairs.
How P2413 is diagnosed properly
Each of the known causes is ruled in or out in cost order, cheapest and most likely first. On P2413 that means working through them like this:
- Carbon-clogged EGR valve or passages — commanded on and off with the diagnostic tool while its current draw and movement are watched, which separates a stuck part from a dead circuit.
- Blocked EGR cooler — measured as a pressure or flow difference across the component, so a partial restriction is not mistaken for a clear one.
- Failed EGR temperature sensor — compared against live data and a known-good reference before it is condemned — a sensor reading the wrong thing accurately is a different fault from a dead one.
- Sticking EGR bypass flap — confirmed with live data before any part is bought.
An hour of diagnostic time on P2413 routinely saves more than it costs, because the alternative is buying the most expensive part on that list and hoping.
The repairs that actually clear P2413
- Clean the EGR valve and inlet passages
- Flush or replace the EGR cooler
- Replace the temperature sensor
After the repair the code is cleared and the car is driven until the relevant readiness monitor completes, rather than handed back as soon as the light goes out. A code that has only been erased will come straight back on the next drive cycle.
What happens if P2413 is ignored
The car will usually keep going, but the fault will not clear itself and the related monitors stay incomplete — which matters if an MOT is due, because a car that has not finished its emissions self-tests can be refused.
For reference, P2413 typically lands at £120–£900 all-in at an independent garage in the UK — main-dealer quotes for the same job usually sit above that.
Getting P2413 looked at
Bob's Mechanical Repairs is an independent garage in Birnam, Dunkeld, Perthshire, with 32 years of Bob's experience on the tools. If P2413 is showing on your car, bring the scan results with you — we will read the live data ourselves, tell you which of the causes above it actually is, and price the repair before any work starts.
