Remanufactured BMW N47N intake manifold

Common fault

In N47N and N47S1 engines, the swirl flaps are mounted on a shared control shaft. Over time, due to high mileage and soot accumulation, excessive play develops where the flaps attach to the shaft. As a result, the flaps begin to move freely regardless of the actuator’s position, and in extreme cases, a flap may snap off. Due to its size, a broken piece rarely enters the combustion chamber; however, the fault itself leads to a noticeable drop in engine performance.

Our solution

Our remanufacturing process utilizes an upgraded flap-to-shaft mounting design, developed specifically to eliminate the root cause of the fault rather than just its symptoms.

The remanufactured intake manifold features:

• An upgraded swirl flap-to-shaft mounting system

• Reinforced shaft bearings

• New shaft seals

• A new intake manifold gasket

• A mechanically and electrically tested actuator

Upgraded N47N swirl flap mechanism design

This solution completely eliminates the risk of recurring failures typical of the original factory design.

Fitment & application

This intake manifold is fitted to BMW 2.0d engines with codes N47N and N47S1 produced between 2011 and 2015.

Full technical specifications, OE numbers, and VIN-based part compatibility checking are available on the product page.

Remanufactured intake manifold Hyundai/Kia 1.4-1.7 CRDi (D4FB, D4FC, D4FD)

The most common causes of 1.4-1.7 CRDi intake manifold failure include:

• faulty mounting of the swirl flap shaft in older generation manifolds (up to 2015 model year), resulting in broken flaps,
• swirl flap bearing wear: for pre-2015 manifolds, this typically affects the last flap furthest from the actuator, which carries the highest load; post-2015, the manufacturer reduced the overall bearing size, causing practically the entire swirl flap bearing system to wear out,
• leaks from the swirl flap shaft seal, leading to boost pressure leaks in the charge air system,
• wear and detachment of the actuator linkage rod in newer generation manifolds (from 2015 model year onwards),
• occasionally: actuator motor wear and Hall sensor damage, resulting in electrical faults such as an unstable or lost flap position feedback signal.

Commercially available swirl flap repair kits replicate the original shaft and bearing design, failing to eliminate the root cause of the breakdown. As a result, the issue recurs in the exact same spot. Our flaps feature a modified shaft mounting design and reinforced bearings, which addresses the root cause of both primary faults rather than merely treating the symptoms. Unlike deleting or blanking the swirl flaps, remanufacturing fully restores the manifold’s original function.

Reinforced intake manifold 1.4-1.7 CRDi – swirl flaps

The 1.4-1.7 CRDi intake manifold remanufacturing process includes disassembly and cleaning, as well as replacing the swirl flaps and bearings with our redesigned version. Every remanufactured manifold undergoes testing and electrical parameter verification of the electronic actuator.

The Opel 1.4T NEL NET intake manifold was fitted in Opel Astra J, Cascada, Corsa D, Meriva B, Zafira C, Chevrolet Cruze and Chevrolet Trax. It is a popular turbocharged engine with an integrated crankcase ventilation system that develops specific, recurring problems over time. We rebuild this manifold on a regular basis and know its weak points inside out.

Where does the damage occur?

The main culprit is the crankcase vent check valve integrated into the manifold. When the valve loses its seal or breaks off, the pressure generated by the turbocharger acts directly on the valve cover, causing damage to its membrane.
The result is oil leaks at the engine seals and fault codes related to boost pressure and air-fuel mixture P0171 (lean mixture), P0299 (boost pressure too low) and P1101 (incorrect air intake flow). Owners frequently replace the valve cover itself, not realising it is the consequence, not the cause.

The second issue is degradation of the gasket flange located in the crankcase vent channel, causing the gasket to fold and leading to leaks.

Our approach to rebuilding

We do not use the standard solution. We repair the check valve using our own method, eliminating the problem at its source. This makes the rebuild long-lasting and eliminates the risk of the fault returning. In addition, every manifold receives a new gasket flange in the crankcase vent channel.

After rebuilding, each manifold is tested for check valve performance.

Most common failure causes of the BMW B47 intake manifold:

Manifold leaks:
In the BMW B47 intake manifold, leaks occur at the swirl flap shaft axis, on the side of the electric actuator. The cause is simultaneous wear of the control lever and the shaft seal. An oil or exhaust gas leak in this area is visible as characteristic contamination around the actuator and can lead to rough engine idle as well as boost and lambda sensor errors when the leak is significant.

Swirl flap play:
The B47 swirl flap mechanism operates in adverse thermal conditions. Carbon deposits and oil create an abrasive “paste”. Over time, play develops on the shafts and flap seats, which, combined with carbon buildup inside the manifold,  leads to gradual flap jamming and prevents their free movement.

Control mechanism wear:
The electric actuator is connected to the swirl flap shaft via a control lever. In the BMW B47 intake manifold, this lever wears over time and in extreme cases detaches completely, causing fault code P2015 (ISTA 2F8500) to appear and the engine to enter limp mode.

Swirl flap jamming:
Carbon deposits accumulating on the flap mechanism cause gradual jamming. A seized flap mechanism is one of the main causes of fault code P2015 (ISTA 2F8500) in the engine ECU, resulting in power loss and the engine entering limp mode.

Carbon contamination of intake manifolds causing swirl flap mechanism jamming

Remanufacturing of the BMW B47 intake manifold at PT-PRO includes cleaning, comprehensive remanufacturing of swirl flaps using new reinforced components, eliminating play in the process. After remanufacturing, each manifold undergoes a leak test and inspection of the actuator’s electrical parameters and operating range.

The most common failure modes of the Volvo 2.0D D4204 intake manifold
include swirl flap jamming caused by carbon deposits (soot buildup)
on the flap mechanism, wear of the swirl flap travel limiter, and
manifold leakage at the central bolt.

These issues lead to rough idle, loss of power and increased exhaust smoke.
Remanufacturing, unlike swirl flap removal, fully restores the
original manifold function and eliminates all three failure points.
