Audi A3 TDI Oil Pressure Warning, Common Fix Guide

Having experienced similar issues with my Audi A4 2.0 TDI from 2015, I can share some relevant insights. The oil pressure warning combined with check engine light often indicates oil quality problems. My car showed identical symptoms, and after inspection, the workshop found significant oil sludge buildup due to extended oil change intervals. The fix involved: Complete oil change with special engine flush, New oil filter replacement, Oil pressure sensor check, Computer diagnostic scan Total cost was 165 Euro and resolved both warning lights. Regular maintenance is crucial, oil sludge can cause serious engine damage if left unchecked. Before suggesting specific solutions, could you share: Current mileage, Last oil change date, Type of oil currently used, Any unusual engine sounds, Other warning lights present These details would help determine if your situation matches what I experienced. Oil additives might help, but proper diagnosis is essential before attempting any fixes. The workshop also recommended shorter oil change intervals for these engines to prevent future issues, especially for cars primarily used for short trips where oil degradation happens faster.

Thanks for the helpful details about the repair procedure. My mileage is currently at 5386 KM since the latest service. The oil has a dark brown color and seems thicker than normal, which might indicate oil contamination. I also noticed a slight oil leak near the filter housing after checking more closely. Having these dual warnings really concerns me about potential engine damage. Will schedule a workshop visit soon to prevent any major issues.

Thanks for providing those additional details. The symptoms you describe, especially the dark, thick oil and leak near the filter housing, are very similar to what I discovered on my Audi before the repair. The oil leak near the filter housing often indicates a worn seal or improperly seated oil filter. In my case, the oil contamination was actually putting extra pressure on these seals, making the leak worse. With just 5386 KM since the last service, the oil shouldnt be severely degraded yet. The combination of oil contamination signs and the leak suggests possible issues with: Faulty oil filter installation, Damaged filter housing seal, Fuel or coolant mixing with oil Based on my experience, get this checked quickly. My repair costs stayed at 165 Euro because I caught it early. The oil pressure warning combined with visible leaks can lead to engine damage if ignored. While waiting for the workshop appointment, monitor the oil level frequently and avoid high-speed driving. The thicker oil consistency you mentioned could restrict proper flow through the engine, similar to what happened with mine before the repair.

Thank you for the detailed explanation about the filter housing and oil contamination risks. Given the leak and warning signs, I will avoid highway driving until the workshop visit next week. Just checked the oil level again and noticed some metal particles on the dipstick, which makes me even more concerned about potential engine damage. The dark color and thickness of the oil definitely seems abnormal for such low mileage since the last service. I will ask them to specifically check the oil pressure system and filter housing seal during the inspection. Really hoping this can be resolved with just an oil change and new seals rather than more extensive repairs. At least catching these symptoms early should help prevent major engine issues. Will update once I get the workshop diagnosis.
