The 1.6-liter Volkswagen 1.6 ALZ engine was assembled at the company’s factories from 2000 to 2010 and installed both on the restyled version of the fifth Passat and on three generations of the Audi A4 at once. This power unit was intended for a longitudinal arrangement under the hood of the car.
The EA113-1.6 series includes: AEH, AHL, AKL, ALZ, ANA, APF, ARM, AVU, BFQ, BGU, BSE, BSF.

Disadvantages of the VW ALZ engine
- The most common problems are floating engine speeds and vibrations.
- To get rid of the unstable operation of the motor helps cleaning nozzles or throttle.
- Also, the reason may be the wear of the rubber seals on the intake manifold.
- In second place in popularity are failures in the operation of the crankcase ventilation system.
- Closer to 200,000 km, an oil burn often begins due to wear of rings or caps.
We have an ALZ engine on a Passat Variant 1.6, B5.5, 2004.
The engine code P0402 keeps popping up, but there are no other symptoms.
Is the 06B133354D air intake tube the same as the 06B133354K or AA? Where the crankcase ventilation pipe connects to the air intake, there is a warp. Would this be sufficient to cause the engine light to come on? I suspect the seal to be less than efficient. The pump suction jet has been renewed, and so has the ECT. I only have a very basic scanner and would be grateful for your advice.
