Can the pp-gf30 cause the code p1401?

Yes, the PP-GF30 (a polypropylene-based material) can be associated with the P1401 code, which typically relates to an issue with the exhaust gas recirculation (EGR) system. If components made from PP-GF30 are used in the EGR system and fail, such as valves or connectors, they could lead to improper EGR functioning, triggering the P1401 code. However, the specific cause would need to be diagnosed based on the vehicle's overall condition and other potential factors.
