Manufactured from 2011-2017, the BMW N20 was basically launched to replace the naturally aspirated 3.0L 6-cylinder N52/N53 engines. Empowered with a beefy turbocharged 4-cylinder engine, the BMW N20 had to fulfil massive expectations, for the previous N52 and N53 engines were touted for its impressive functionality. Things might go wrong with the turbo charged engines because of their complicated components. However, the N20 turns out to be a reliable engine without too many issues.

BMW N20 Common Engine Problems:
While the N20 is a dependable engine, the preceding models often experience timing chain issues that may be costly to fix. The latest models don’t suffer these issues, though, which were more and less common with other models. Instead, the N20 is subject to many other issues that are not necessarily common. This is because a small percentage of engines experience these issues. Let’s check out the most common issues on the BMW N20.
Timing Chain:
One of the major problems on the N20 is the timing chain malfunction - an issue which is more prevalent on engines and cars built before 2015. In 2015, BMW replaced the timing chain components in order to reduce the risk of failure. If you notice any issue with your timing chair, bring your car in at an independent BMW service Greensboro shop.
Symptoms of BMW N20 Timing Chain Failure:
Some of the most common signs of timing chain failure include loud whining from engine, significant scoring on chain, too much slack and so on. The feeble whimpers coming from the engines under light revs/acceleration is a plain indication of timing chain failure. An excessively loud whine, substantial scoring and scratching on the chain points to the issue.
Other BMW N20 Engine Problems:
On the N20, the timing chain seems to be the most serious problem. There may be certain frequent concerns that arise when engines age due to wear and tear. Let’s go through a couple of issues that may be due to common "wear and tear".
N20 Valve Cover and Valve Cover Gasket:
BMW N20 uses a plastic composite valve cover and rubber valve cover gasket. Due to increased mileage and age, the valve cover may become brittle and start to crack. It could be due to the nature of heat cycles where the engine and components heat up and cool down constantly. To keep your engine running strong, consider BMW Greensboro NC for tuneups and routine maintenance.
Symptoms of Valve Cover and Gasket Leaks:
Without activating the air recirculation, drivers may sense a burning oil smell within the cabin when the A/C or heat is turned on. As the leaked oil drips into the exhaust or turbocharger, smoke from the engine bay is likely to become prevalent.
