I’m considering replacing my VANOS solenoid, and while I usually stick with OEM when buying components, I wanted to hear from others to see if there was a difference between aftermarket (eBay and Amazon) solenoids and OEM solenoids.
The cost difference between aftermarket Solenoids (2 for $40) and OEM Solenoids (2 for $320 on FCP) is substantial. Has anyone used the aftermarket solenoids before?
Most likely, new vanos solenoids won’t make 30ff go away. 30ff is probably due to fried turbos even though I have new solenoids and other components.
However, try Rock Auto and search for Standard Motor VVT207 if you do decide to replace your vanos. They were probably produced in the same plant as the original equipment manufacturer and are made in Germany.

For many items, we are aware of the OE makers, but I’m not sure if I’ve ever noticed who makes the vanos solenoids. Undoubtedly, one aftermarket supplier is the original equipment manufacturer. Continental is what I’m assuming, but I’m not sure.
I was just looking at this new BMW one I have around, and there aren’t any markings from any other manufacturer. One of these part numbers might be linked to a manufacturer by someone.

I looked for the means to make some after discovering that BMW had ripped off the VANOS solenoid.
As can be seen in the following screenshot, my car once had a minor difficulty with VANOS in Bank 2:
I installed two solenoids that were supplied by a supplier who is reputed to be an expert in creating and producing automotive parts. Only the two solenoids in Bank 2 were replaced. The test results seem promising.
On August 27, I installed the two test units on my beast, and they have been working flawlessly for more than 1200 miles since then.
I’ve begun producing a small batch. The selling price for each solenoid should not exceed $120 once all expenses are considered. Not sure if anyone is looking at this?
What BMW engines are VANOS equipped?
The BMW VANOS engine with a valve timing system is most likely found in any BMW vehicle built in 1993 or later. The effectiveness, power, and efficiency of an engine are determined by valve timing. You must learn how VANOS engines operate, what they are made of, and how to spot failure symptoms if you want to drive your BMW safely and keep it in top shape. These specifics are listed below.
Vanos solenoids can they be switched?
According to my understanding, the article is referring to the helical geared VANOS units, not the solenoids that operate the intake and exhaust camshaft angles, which move and alter them. Given that they are interchangeable and similar, the VANOS solenoids (same part number). I recently replaced mine with all-new components from BMW, and the N52 is the same.
What exhaust VANOS solenoid is this?
The top one is for the intake camshaft, while the lower one is for the exhaust camshaft. 2. Remove the bolt holding the Vanos solenoid in the cylinder head using a 10mm socket and pull it out.
Why does the BMW VANOS malfunction?
Typically, o-ring failure and solenoid clogging are the two issues that lead to VANOS system failure. To control the engine’s cams, the VANOS system uses pistons, which are sealed by rubber o-rings. These o-rings will eventually degrade as a result of prolonged exposure to harsh conditions like high temperatures, high pressures, and corrosive chemicals. The pistons in the VANOS system won’t be able to operate as a result, which could result in a total engine failure. O-ring failure can therefore be disastrous if it is not discovered and addressed in a timely manner.
Similarly, a malfunctioning VANOS system in your BMW could be brought by by blocked solenoids. The VANOS system can intervene between the cam gear and the cam thanks to the solenoid, a small component that flows oil through the system. Solenoids, like all parts of a car that use oil, can eventually get dirty and clogged. If the accumulation becomes excessive, the solenoids could malfunction and render the VANOS system ineffective. Again, the engine of your car may suffer significantly as a result.
Are VANOS and VVT solenoids interchangeable terms?
These components may also be known as camshaft actuator solenoids, oil control solenoids, VANOS solenoids, and a plethora of other names depending on the vehicle manufacturer. However, despite the various nomenclature schemes, all VVT solenoids perform the same function: To activate the mechanism that modifies valve timing, add oil pressure.
Why does a VANOS solenoid malfunction?
Several problems could result in VANOS failure. O-ring failure is the initial problem. Since these rings are composed of rubber, they may naturally degrade with time.
The solenoids, which might develop clogs, are the second most frequent problem. The solenoids won’t function properly if dirt and other materials obstruct them.
How durable are n54 VANOS solenoids?
50,000 Miles Seals are used throughout the building of your BMW’s Vanos system. The seals deteriorate over time as a result, and they usually require replacement after 50,000 miles.
What regulates VANOS?
The DME engine management system of the car controls the combination of mechanical and hydraulic camshaft control methods used by VANOS. The intake camshaft position can be altered via the VANOS system.
Does VTEC resemble VANOS?
According to my Google searches, Vanos is just variable valve timing, which many manufacturers use. Instead of only altering the valve timing, VTEC also modifies the cam profile.
The cost of a VANOS unit
I believe the vanos in my engine base needs to be changed because it has been rattling. Does anyone have any idea how much it would cost to get it fixed at a shop? My car now has 94k miles on it, therefore I believe it’s time to get that fixed.
Yes, a company will charge you a fair sum for labor; it will generally cost between $400 and $500 to complete the task. Additionally, they presumably won’t employ any upgraded seals, which means the issue will resurface soon.
Your best option is to either buy the Dr. Vanos and have a shop install it for you, use Beisan Systems or Dr. Vanos and do it yourself. To be clear, the Beisan Systems demands that you take apart your VANOS unit and rebuild the seals on your own. You buy a unit from Dr. Vanos with the new seals already in place, then you just swap them out and send the old one back for a core charge.
You shouldn’t need more than a good Saturday or Sunday, in my opinion. similar to changing the timing belt on an E30.
Since the plastic keyhole tends to deteriorate over time and permit extra movement, it’s also possible that your DISA valve is chattering. Fortunately, it’s a simple issue to check/fix. I thought the rattling I heard was caused by my VANOS, but it was actually a DISA butterfly valve that was loose.
I’m thinking of getting a shop to install the Dr. Vanos kit. The new Vanos will run you about $600-$700 in labor costs alone (less the core charge for the original Vanos equipment from Dr. Vanos). and that doesn’t even include the valve cover gasket, which, if not already done, should be done at the same time (add $400 for parts and labor, although it seems the VCG is not too difficult a DIY if you’re feeling ambitious).
How do VANOS codes work?
- P1520: Exhaust camshaft position actuator.
- P1523: Exhaust and a jammed camshaft position actuator.
- Camshaft position sensor B, code P1397.
- Vanos intake solenoid, 2A82.
- Vanos exhaust solenoid, 2A87
What is the price of rebuilding VANOS?
An typical Vanos solenoid replacement costs roughly $600. $200 will be spent on parts, and $400 will be spent on labor. Usually, the range is $300 to $800. Different Vanos systems used by different BMW engines may cost more than others.
The cost to replace the Vanos solenoid on different well-known BMW models is shown in the table below. These costs are averages and will vary based on the age of your vehicle and the location of your technician.
As you get closer to the less expensive economy-style versions, replacement prices typically tend to go down.
Does VANOS suffer with low oil?
On a 2008–2010 BMW vehicle, the “Service Engine Soon” indicator can come on and the engine power may be diminished. After a while of driving with the engine at working temperature, this may happen. If the ignition is restarted, the engine might then run as it should.
The DME may contain the following faults:
Note: BMW refers to its variable cam timing technology as VANOS. The following secondary faults for the N54 engine could be saved:
An inadequate oil pressure feed to the intake VANOS adjustment unit may be the root of the VANOS failures. A adequate oil pressure supply to the VANOS control pistons must always be available in order to move the camshafts to the desired positions in the allotted time and under all engine circumstances. If the intake or exhaust camshafts must be quickly advanced or retarded during engine operation, the VANOS system may record faults if the camshaft is “late” or does not reach the desired position. Engine power may be lowered in this circumstance, and a check control message may be shown. The DME fault memory can also be programmed to store the consequence faults 3100 or 120408.
Completely execute each test plan that applies to the recorded faults. Insufficient oil delivery to the VANOS assembly can also be brought on by a mechanical limitation or electrical failure of the VANOS solenoid and/or the electrical circuit. Go to Step 2 if the findings of the finished test plans are unclear.
It’s possible that when the vehicle’s last oil service was performed, the oil filter cap insert was accidentally taken out. The engine will receive non-filtered engine oil if the insert is not inserted, which could clog or harm the VANOS solenoids. The entire oil filter housing cap needs to be changed if the oil filter cap insert is found to be missing.
Change the engine oil and filter, both VANOS solenoids, and service data (when applicable). The camshaft hook ring seals should be inspected while carrying out the test programs for VANOS defects. Examine the camshaft bearing ledges for wear. Only swap out the affected camshaft’s rectangular hook rings and bearing ledge if necessary. Don’t swap out the camshaft (s).
How can I tell if my VANOS is malfunctioning?
The VANOS system is concerned with maintaining your engine’s power, efficiency, and economy at optimal levels. You will most likely start to detect problems in those three areas as the system begins to fail, such as:
- lower RPM ranges experience a loss of power
- an underpowered engine that lags down and hesitates
- Increase in engine misfires and rough idling
- an increase in gasoline usage
- lower fuel efficiency
- Having trouble with cold starts
- freezing in a cold climate
- The check engine light can come on.
- The power of the engine may decline following a sudden acceleration.
It’s simple to understand how the aforementioned problems could utterly sabotage your driving enjoyment, making operating your BMW irritating and possibly dangerous. For the sake of your safety and the protection of your passengers, it is advisable to resolve VANOS failure as soon as feasible.

Since 1992, BMW has utilized the variable valve timing (VVT) system on a variety of gasoline-powered automobiles. The name is an acronym for variable camshaft timing in German (German: variable Nockenwellensteuerung).
The latter “double VANOS” systems are used on both the intake and exhaust camshafts, in contrast to the earlier version, which was retroactively called “single VANOS,” which was only used on the intake camshaft. Since 2001, VANOS and the valvetronic variable valve lift system have frequently been utilized together.
