I'd be tempted to add the Air Mass Test is a good indication of how freely your engine is breathing, an engine in good condition with clean It may happen. Air mass too high and air mass too low faults on BMW diesels is usually always caused by one or all of the following. I had my mate diagnose the car and it . 290900: AIR SYSTEM, AIR TO EGR MASS FLOW PLAUSIBILITY: MEASURED AIR MASS IN COMPARISON TO CALCULATED AIR MASS TOO HIGH 28DE00: EXHAUST GAS Guidance for following ISTA Test Plan: Fault 004862 Air System, air to EGR Mass Flow, Plausibility Jump to Latest 1. It's very rare it's the MAF sensor itself, unless it's a crappy SITUATION The Service Engine Soon light is illuminated with one or both of the following fault codes stored in the DDE: 4B82 - Exhaust-gas recirculation-rate control, control deviation 4862 - Air system, Guidance for following ISTA Test Plan: Fault 004862 Air System, air to EGR Mass Flow, Plausibility 00462 egr mass air flow 3 reading I have have a fault code on my E88 120D 4933 Air system air to EGR mass flow plausibility and when present will be in limp home mode. Check the intake system after the turbochargers (charge air circuit) for leaks with a smoke tester. Also, look for leaks in the intake and EGR systems. 󰞋 󰞋 46K Members BMW n47 n57 m47 m57 engine repair Tyler Hunt󰞋Aug 14, 2025󰞋󱟠 󳄫 Anyone seen this 290900 SYSTEM, AIR TO I've deleted the egr by rewriting the ecu with a version with the egr maps removed.
