Where Should You Go in Dallas to Repair Your BMW’s VANOS System?

Posted on | 20 Apr 2020 By Anita Gaal

While all manufacturers will have their own named and branded rendition of a common car part, some brand-specific variants stand out from the rest. This is definitely the case with BMW’s game-changing VANOS system.

The VANOS system took the concept of Variable Valve Timing and elevated it to a whole new level, revolutionizing the way that driving felt. It showed drivers that you can have your cake and eat it too, with increased power and smoothness, where previously it had always been a choice between the two.

It is amazing to know that this revolutionary part largely goes untalked about and that many BMW drivers simply don’t know of its existence, though we can guarantee they definitely know when it fails! Let’s pay homage to the VANOS system and look at what it does and why seeking quality repairs is essential.

The VANOS System

As mentioned, the VANOS system is BMW’s rendition and improvement of the variable valve timing. VANOS is actually an acronym of the German tongue-twister “VAriableNOckenwellenSteuerung.” It debuted in BMW models in the early 1990’s.

The VANOS system is designed to improve the overall performance of the engine by making some moderations. It improves the engine’s intake and exhaust valves, modifying them so they can open and close as needed. This simple change is what makes such a vast improvement to engine performance.

Secondly, the VANOS system is able to make the engine’s timing hyper-accurate by controlling how much engine oil reaches the cam gears. All of these subtle changes made by the VANOS system add up to increased engine performance, smoother driving and idling, increased powerband elasticity, and a lot more torque.

Depending on the age of your BMW, your car will likely have one of three renditions of the VANOS system: Single VANOS, Double VANOS, or Double Vanos with Valvetronic.

Maintaining, Repairing, and Replacing the VANOS System

Though what it does to the engine is quite simple, the VANOS system itself is a high-tech piece of engineering. This can mean that repairs require expertise, which can result in expense. It isn’t worth trying to save money by undertaking VANOS repair at home. The tools needed to complete the job are far more expensive to purchase than hiring the help of an expert mechanic, who can also give you piece of mind that the job has been completed successfully.

It’s definitely also worth remembering that the VANOS system works in direct connection to your engine, your BMW’s most costly and essential part. Therefore, if things go wrong with your DIY project, you could accidentally end up writing off your BMW or being left with one hefty repair bill. It’s just not worth the risk.

When selecting a professional to repair, replace, or service your VANOS system be sure to select a BMW specialist. As mentioned, the VANOS system is an innovation unique to BMW, so you want to make sure that the individual working on your car has experience with the VANOS system.

When it comes to maintaining your VANOS, the key to a long, trouble-free lifespan is regularly-scheduled servicing. Having your car regularly inspected by a mechanic will help ensure any rising issue is nipped in the bud and won’t develop into something more severe. You can also take an active role in safeguarding your VANOS system by caring for and maintaining your engine oil. With these two simple steps, you can help guarantee your VANOS system doesn’t fail you prematurely.

VANOS systems last upwards of 70,000 miles if cared for correctly. However, the seals used within the system should undergo regular servicing and may need replacements after 50,000 miles.
