Reasons for Low Oil Pressure Alarm in Roewe i5

[LillianaAnn]

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.

Last time I was driving my Roewe i5 on the highway when suddenly the oil warning light on the dashboard came on, which scared me so much that I immediately pulled over. After getting it towed to the 4S shop, the mechanic said the engine oil was more than a liter low, probably because I hadn't checked the dipstick after driving nearly 10,000 kilometers since the last maintenance. They also mentioned it could be due to an aging oil pump seal causing leaks or the sensor being clogged with sludge and giving false alarms. After changing the oil and the seal, the problem was resolved. This was a profound lesson for me—now I check the oil level with the dipstick every two weeks and make sure to do maintenance on time. If you ever encounter this situation, don't worry about where you're going—stop and turn off the engine immediately. Wait a few minutes before checking the oil level. If it's low, add some as an emergency measure, then go straight to a professional for repairs. Don't take chances and keep driving, or you might end up with a burned-out engine and a hefty repair bill.

What I fear most while driving is the sudden illumination of a red warning light on the dashboard, especially critical alerts like low oil pressure that should never be ignored. The mechanic explained that there are primarily two causes: either the engine oil level is insufficient (daily road bumps or leaks can deplete it), or there's an issue with the lubrication system, such as a faulty oil pump or clogged oil passages. If I encounter this situation, my first step is to safely pull over, pop the hood, locate the yellow-ringed dipstick, wipe it clean, reinsert it, and check the oil level. If it's below the minimum mark, I immediately top it up with the same specification oil, being careful not to overfill. Should the warning persist after restarting, it's straight to the repair shop—prolonging this issue can lead to complete engine failure. Safety always comes first; never push your luck.

I'm quite familiar with the Roewe i5. The oil pressure warning light essentially indicates insufficient oil supply in the lubrication system. Oil is pumped from the oil pan to lubricate the engine. If the oil level is low, the oil pump is worn out and weak, or the filter is clogged with debris, the pressure will drop. Another possibility is a false alarm caused by damp or corroded wiring or sensor connectors, which is a minor issue. The solution is simple: first, park the car and check the oil dipstick level when the engine is cold. If it's below the minimum line, top up the oil. After topping up, start the engine and wait a few minutes to see if the warning persists. If the warning light remains on, carefully inspect the pump's operating sound and the filter's condition. If you can't handle it yourself, seek professional help immediately—don't waste time trying to fix it on your own.

I pay special attention to vehicle maintenance, and I always supervise the mechanic when changing the engine oil for my Roewe i5. The root cause of low oil pressure warning is insufficient engine lubrication, commonly due to expired oil being too thin or insufficient oil volume. Long-term failure to change oil can lead to filter clogging. Additionally, engine wear or oil leaks in the oil passages can also cause pressure drops. To prevent this, it's essential to use the manufacturer-recommended oil viscosity on schedule, such as 5W-30 as stated in the manual, and avoid cheap, low-quality oil. Check the oil dipstick level monthly, keeping it between the upper and lower limits. If the warning light comes on, stop immediately to inspect—protecting the engine is more important than anything, as repairs can be extremely costly.
