hi
i have problem with this car . I replaced all sensors and mehanic did motor job.Sensors are ok , lines are ok , pressure is ok but ecu still, send message WARNING OIL PRESSURE LOW . I find some solution but need corect solution ,is kombi instrumemt maybe not ok? need to test eu file please help
SW: 03L906018JG
SW version: 9978

Hi
I had the same problem; I resolved it by replacing the hydraulic lifters and the camshaft lobes. Upon disassembly, I discovered three hydraulic lifters that had lost their prime in cylinder 4. The diagnostic data for the injectors showed a deviation specifically in cylinder 4, and when starting the engine cold, I could hear them tapping—that’s why I decided to replace them. I drove with this issue—a lack of oil pressure (when the engine was hot)—for four years, covering nearly 45,000 km. My advice: fix the mechanical fault, don’t just remap the software!

Before replacing the hydraulic lifters, I unsuccessfully replaced the vacuum pump and 10 original oil pressure sensors (one at every oil change), and I was changing the oil every 5,000 km—all to no avail. I see you have the 9978 "Dieselgate" firmware; it’s clear you’re experiencing frequent regenerations (check the exhaust gas cooler’s vacuum-actuated mechanism—it tends to seize up on this model). I recommend replacing the entire unit, including the EGR valve (Valeo).
