Reasons for Low Oil Pressure Alarm in Roewe i5
2 Answers
Reasons for low oil pressure in Roewe i5 are as follows: 1. Whether the oil filling amount is sufficient, if insufficient, it will lead to insufficient oil pumping by the oil pump and result in low oil pressure; 2. Metal debris in the oil clogging the oil pump filter screen, oil filter or oil passages; 3. The oil brand filled is inappropriate or the oil has deteriorated; 4. Faulty oil pressure alarm causing false low oil pressure warnings; 5. Oil pressure is a systemic issue, it is recommended to go to a 4S shop for detailed inspection. The following are the reasons for oil burning: 1. Carbon deposits are the root cause of various engine problems. Carbon deposits accumulate in the piston grooves, causing the piston rings to stick together and reducing the oil scraping and sealing ability. 2. Sludge can also block the oil return holes, preventing the oil from returning normally, leading to increased oil consumption. 3. Carbon deposits further aggravate the wear between the piston and cylinder wall, creating excessive gaps and allowing oil to enter the combustion chamber. 4. Corrosion and aging of the valve oil seals, resulting in poor sealing.
I've been repairing cars for over ten years and have seen many Roewe i5 owners complain about oil pressure warnings. The most common issue is insufficient oil level—many people simply forget to check the dipstick, and the oil pan ends up dry. If the warning appears soon after an oil change, it could be due to an aging oil pump or a clogged filter, preventing oil flow and pressure buildup. Also, older cars with excessive sludge can have oil passages as clogged as a sewer, restricting oil circulation and triggering the alarm. Never underestimate this problem—metal-on-metal friction inside the engine is like sandpaper grinding on iron, and it can destroy bearing shells in minutes. My advice: first, check the dipstick yourself. If the level is low, top it up with the same oil type. If the warning persists after driving, head straight to the repair shop for diagnosis. Don’t skimp on maintenance—regular oil changes and cleaning the oil passages are key. An engine overhaul costs way more than a few thousand bucks.
