The power unit mounting system in the concern's cars Volkswagen Group plays a critical role in the comfort and durability of the drivetrain. For model Skoda Octavia A5, which was produced from 2004 to 2013, the issue of wear of engine mounts is especially acute due to the design features of the suspension and high loads on rubber-metal elements.
Many owners experience steering wheel vibration or knocking noises during acceleration, not suspecting that the reason lies precisely in destruction engine mounts. Ignoring this problem can lead to displacement of the power unit, damage to the muffler corrugation, rupture of cooling hoses, or even breakdown of the gearbox.
Design and functions of engine mounts in the Skoda Octavia A5
In the car Skoda Octavia A5 a complex system of several supports is used, each of which performs its own unique task. Main function front support — dampen longitudinal vibrations that occur during a sharp start or engine braking. The rear and side supports are responsible for holding the engine in a vertical plane and absorbing vibrations from the operation of the cylinders.
The materials from which these elements are made are a combination of steel and special rubber. Over time, the rubber hardens, cracks, or peels off from the metal casing, losing its shock-absorbing properties. This is especially true for hydraulic support, which contains a special liquid inside for better damping of resonances.
It is necessary to understand that the destruction of one element upsets the balance of the entire system. If you replace only one support, and the rest are already worn out, the new part will quickly fail due to increased loads.
Main symptoms of malfunction and diagnostics
The first and most obvious sign of wear is the appearance of strong vibrations in the steering wheel and in the passenger compartment when the engine is running at idle speed. You may notice that the vibration goes away if you press the clutch or put the transmission in neutral, which immediately indicates a problem with the mounts, and not with the engine.
When you press the gas pedal sharply, you may hear a characteristic metallic knock or click, which occurs when the engine suddenly “jumps” and hits the body due to lack of damping. It is also worth paying attention to the behavior of the car when starting off - twitching may indicate a displacement of the power unit.
A visual inspection of the engine compartment often reveals cracks in the rubber bushings or complete tearing of the damper. In some cases, you can see how the rubber element has peeled off from the metal cup. For accurate diagnosis, it is recommended to use an inspection pit or a lift to assess the condition of the lower fasteners.
Selection of original spare parts and high-quality analogues
When purchasing spare parts for Skoda Octavia A5 It is worth focusing on trusted manufacturers, since the market is filled with low-quality fakes. Original parts from Skoda or Volkswagen usually have part numbers starting with 1K0 and provide maximum service life, but their price can be high.
Brands are a good alternative Lemförder, Sachs and TRW, which often supply spare parts to the assembly line. These manufacturers use high-quality rubber compounds and durable steel, which allows them to last almost as long as the original. Avoid cheap Chinese analogues of unknown brands, as they often become tanned after just a few months of use.
Pay attention to hydraulic supports: they are more sensitive to workmanship. If you see traces of oil leakage from the hydraulic support, this is a sure sign that it requires immediate replacement, since the damping efficiency in this case is zero.

Step-by-step instructions for replacing the engine mount
Replacing an engine mount is a labor-intensive procedure that requires special tools and some skill. You will need a jack or stand to support the engine, as once the mount is unscrewed, the power unit will lose its mounting point and may fall.
First you need to loosen the support mounting bolts, but do not unscrew them completely. Then a jack with a wooden spacer is placed under the engine to protect the oil pan. After this, the mounting bolts are unscrewed and the old support is removed. Before installing a new part, make sure that all threaded connections are clean and undamaged.
Installation of the new support is carried out in the reverse order. It is important to tighten the bolts only after the engine has been lowered into its original position and has assumed its normal position under its own weight. This will ensure proper tension on the rubber elements and prevent premature wear.
☑️ Preparing to replace the engine mount
Features of working with hydraulic support
The hydraulic support is sensitive to an inverted position. If you install it upside down during installation, the valve inside may be damaged and the support will lose its properties. Always pay attention to the orientation of the part when installing.
The nuances of replacing the gearbox support and rear support
Often, along with the front engine mount, the transmission mount fails, especially on cars with automatic transmission. In design Skoda Octavia A5 with automatic transmission gearbox support takes on huge loads when changing gears. Replacing it requires removing or significantly lowering the subframe, which significantly complicates the work.
The rear engine mount, often called the "bone", is also subject to rapid wear. When replacing it, it is necessary to take into account the tightening torque of the bolts, since incorrect torque can lead to rupture of the rubber. It is recommended to use a torque wrench for fine tuning.
If you have a version with a 1.6 MPI engine, the replacement process may be easier than for turbocharged versions, where the layout of the engine compartment is tighter. In any case, access to the rear support is often limited by exhaust system components and heat shields.
Before starting work, be sure to photograph the location of all bolts and hoses so as not to get confused during assembly. This is especially important if you are making the replacement yourself for the first time.
Table of estimated prices for spare parts and labor
Engine mount replacement costs may vary depending on region, engine type, and service chosen. Below are the average market prices for original spare parts and replacement services for the model Skoda Octavia A5.
| Part name | Approximate price (RUB) | Cost of work (rub.) |
|---|---|---|
| Front engine mount (original) | 8 500 - 12 000 | 3 500 - 5 000 |
| Transmission support (hydraulic) | 7 000 - 10 000 | 4 000 - 6 000 |
| Rear support ("bone") | 3 000 - 5 000 | 2 500 - 4 000 |
| Mounting bolt kit | 500 - 1 200 | Included in work |
⚠️ Attention: When replacing hydraulic mounts, never turn them upside down before installation. This can lead to valve failure and loss of damping properties of the new part.
Common replacement errors and their consequences
One of the most common mistakes is tightening the mount bolts before the engine is in its normal position. If you tighten the bolts while the engine is hanging on a jack, the rubber bushing will be constantly in a stretched or compressed state, which will lead to its rapid destruction.
Another mistake is using old bolts. Many manufacturers recommend using new fastening bolts, as old ones may have stretched threads or hidden damage. Reusing old fasteners may cause them to break while driving.
Some craftsmen ignore the need to replace all worn supports at once, replacing only one. This creates an imbalance of loads, and the remaining old supports begin to work in overload mode, which reduces their service life to a minimum.
The correct sequence of tightening the engine mount bolts is critical: first loosen all fasteners, lower the engine, then tighten the bolts to the recommended torque.
⚠️ Attention: If you notice that the bolts do not tighten completely when replacing the support, do not use excessive force. This may mean that the holes in the body or engine have become misaligned and additional powertrain alignment is required.
Prevention and service life extension
To extend the life of your engine mounts, try to avoid hard starts and extreme loads on the transmission. Smooth pressing of the gas pedal reduces dynamic loads on engine mounts and reduces the risk of premature destruction of rubber elements.
Perform a visual inspection of the engine compartment regularly, especially if you notice any unusual sounds or vibrations. Early detection of cracks in the rubber will allow you to replace the part before it completely breaks down and causes problems with other parts of the car.
Timely replacement of technical fluids and monitoring the condition of the engine also indirectly affect the durability of the supports. If the engine runs unevenly or intermittently, vibrations increase, which accelerates the wear of all rubber-to-metal joints.
How to check the condition of supports without a lift
You can use a pry bar to rock the engine slightly. If you feel a lot of play or hear a knock, it means the support is worn out. Be careful not to damage other components.
What symptoms indicate a faulty engine mount in the Skoda Octavia A5?
The main symptoms are strong vibration of the steering wheel at idle, metallic knocks when accelerating or braking the engine, as well as visual cracks or tears in the rubber support elements. If the vibration goes away when you shift into neutral, the problem is almost certainly in the mounts.
Is it possible to drive with a faulty engine mount?
It is not recommended to drive with a faulty airbag, as this can lead to engine displacement, damage to hoses, rupture of the muffler corrugation, and even damage to the gearbox. In addition, vibration is transmitted to the body, which reduces comfort and can lead to fatigue of the body metal.
How much does it cost to replace an engine mount at a service center?
The cost of replacing one engine mount averages from 2,500 to 6,000 rubles, depending on the difficulty of access and the type of mount (hydraulic or rubber). It may cost more to completely replace a set of supports, but it will ensure that the entire system is balanced.
What analogues of original engine mounts are best to buy?
Brands are considered the best analogues Lemförder, Sachs and TRW. They produce parts that are often installed on a conveyor belt and have high quality rubber compounds. Avoid cheap Chinese analogues, as they quickly lose their elasticity.
Do I need to change all the pillows at once or can I change them one at a time?
It is recommended to replace all worn supports at once, since replacing one new support while the others are worn out creates a load imbalance. This will lead to the new part quickly failing, and the old ones will continue to deteriorate. Complex replacement ensures uniform distribution of vibrations.
