P2004 means the intake manifold runner flaps are stuck in the open position. These flaps change the length of the intake path to optimise airflow at different RPM ranges. When stuck open, the engine loses low-speed torque and may run roughly at idle because airflow is optimised for high RPM only.

P2004 est un code defaut lie a systeme de carburant, classe en gravite moderate. Lorsque le calculateur de ton vehicule detecte cette condition, il enregistre P2004 et allume le voyant moteur.
Si ton vehicule a declenche P2004, tu peux remarquer un ou plusieurs de ces symptomes :
Voici les causes les plus courantes de P2004, classees selon la probabilite qu'elles soient en cause :
En general oui, pour des trajets courts. Generally safe to drive short-term. You may notice reduced low-end torque and slightly higher fuel consumption. Have it repaired within a few weeks to avoid secondary issues.

P2004 se comporte differemment selon ton vehicule. Selectionne ta voiture ci-dessous pour des causes propres au modele, les problemes connus et des estimations de couts ajustees :
2004-2024
The Golf Mk5 and Mk6 with the 2.0 TFSI (EA113/EA888) and 2.0 TDI (EA189/EA288) engines are extremely prone to intake manifold runner failures. The plastic flaps crack and the metal linkage rods wear through their pivot points. Aftermarket repair kits from manufacturers like Victor Reinz and Febi are widely available and are the recommended fix.
2005-2024
The A4 B7 and B8 with the 2.0 TFSI engine shares the same intake manifold design as the Golf and is equally prone to P2004. On the A4, the manifold is slightly harder to access due to engine bay packaging. The 3.0 TDI V6 also has runner flaps but they fail less frequently.

2004-2024
The Octavia with 2.0 TFSI and 2.0 TDI engines uses the same VAG intake manifold as the Golf and A4. The same repair kits and procedures apply. The Octavia's engine bay offers slightly better access than the A4, making DIY repair more feasible.

The Leon shares its 2.0 TFSI and 2.0 TDI engines with the VW Golf and is equally affected. The intake manifold part numbers are identical. SEAT dealerships often recommend full manifold replacement, but the aftermarket repair kits are a proven and much more economical solution.

Ces codes apparaissent souvent avec P2004 ou indiquent des problemes connexes :
P2004 means the intake manifold runner flaps are stuck open. These flaps adjust airflow through the intake to optimise torque at different engine speeds. When stuck open, you lose low-end power and fuel efficiency.
Yes, short-term driving is safe. The engine will run but with reduced low-speed torque and potentially rough idle. On VW/Audi models, broken flap pieces can potentially be ingested into the engine, so prompt repair is recommended.
The VAG 2.0 TFSI and 2.0 TDI engines use plastic intake manifold flaps connected by thin metal linkage rods. The plastic flaps become brittle over time and the linkage wears, making this one of the most common faults on these engines.
Aftermarket repair kits with upgraded flaps and linkage are available for 40-150 EUR. These are a reliable and much cheaper fix than replacing the entire manifold (200-600 EUR for the part alone).
If a plastic flap breaks apart, fragments can be sucked into the combustion chamber and cause scoring on the cylinder walls or valve damage. This is rare but possible, especially on direct-injection engines where the flaps are close to the intake ports.
