P1572 (Volkswagen, Audi, Skoda, Seat) Left Electrohydraulic Engine Mount Solenoid Valve - Short to Ground

P1572 - OBD-II Trouble Code Technical Description

Trouble code P1572 indicates a short to ground in the left electrohydraulic engine mount solenoid valve circuit in Volkswagen, Audi, Skoda, and Seat vehicles.

What does the fault code mean P1572?

Trouble code P1572 indicates a short to ground in the left electrohydraulic engine mount solenoid valve circuit. This valve controls the supply of hydraulic pressure to the engine mount, which in turn affects the level and stability of the vehicle's suspension. A short to ground means that the solenoid valve circuit has been inadvertently connected to ground. This can cause the valve to malfunction, break, or shut down, which can ultimately affect the performance of the engine mount and the stability of the vehicle's chassis.

Possible reasons

Some possible causes of the P1572 trouble code:

• Damaged or broken wiring: The wiring connecting the solenoid valve to the rest of the electrical system may be damaged, broken or stripped, causing a short to ground.
• Damaged solenoid valve: The valve itself may be damaged or worn, which may result in a short to ground.
• Problems with the central control unit: Faults in the central control unit, which controls the operation of the solenoid valve, can also cause a short circuit to ground.
• Corrosion or oxidation of contacts: Corrosion or oxidation of contacts in connectors or connections can create additional resistance, which can cause a short circuit.
• Mechanical damage: Mechanical damage such as misaligned or blocked wiring can cause a short circuit.
• Malfunction of other system components: Failures of other components related to the electro-hydraulic engine mount system, such as relays, fuses, or sensors, can also cause code P1572.

To accurately diagnose and fix the problem, it is recommended to contact an experienced auto mechanic or an authorized service center.

What are the symptoms of a fault code? P1572?

Symptoms for DTC P1572 may include the following:

• Check Engine Light: The Check Engine light on the instrument panel will illuminate, indicating a problem with the system.
• Unstable engine performance: Vibrations or uneven operation of the engine may occur due to improper positioning or support of the engine by the electro-hydraulic mount.
• Knocks and noises: When the vehicle is driven, unusual knocking or noises may occur, especially when driving over bumps or on uneven roads, due to insufficient engine support.
• Decreased productivity: There may be a decrease in engine power and performance due to unstable operation of the electro-hydraulic mount.
• Vehicle instability: The vehicle may become less stable on the road, which will be especially noticeable when turning or braking sharply.
• Vibrations in the cabin: Passengers may experience vibrations in the vehicle interior due to improper operation of the right electro-hydraulic engine mount.

If you notice one or more of these symptoms, it is recommended that you have the problem diagnosed and repaired as soon as possible to prevent further damage and ensure the safe operation of your vehicle.

How to diagnose a fault code P1572?

The following steps are recommended to diagnose DTC P1572:

1. Reading fault codes: Using a diagnostic scan tool, read the fault codes in the electronic engine management system. In addition to the P1572 code, also look out for other codes that may further indicate problems with the system.
2. Checking the solenoid valve: Check the condition of the left electro-hydraulic engine mount solenoid valve. Check wiring and connections for corrosion, breaks or shorts.
3. Checking the wiring: Carefully check the wiring to the solenoid valve for damage, breaks, corrosion or short circuits. Make sure all connections are secure and connected correctly.
4. Checking the central control unit: Check the condition and operation of the central control unit that controls the operation of the solenoid valve. Make sure that the control unit is functioning correctly and is not damaged.
5. Checking other system components: Check other components of the right electro-hydraulic engine mount system, such as sensors, relays or fuses, that may be related to the problem.
6. Testing the system on a lift: It may be necessary to lift the vehicle to check the condition of the electro-hydraulic engine mount and its components.

After diagnosing and identifying the cause of the problem, make the necessary repairs or replace the defective components to eliminate the problem. If you are not confident in your diagnostic skills or do not have the necessary equipment, it is better to contact a professional auto mechanic or an authorized service center to perform a professional diagnosis.

Diagnostic errors

When diagnosing DTC P1572, the following errors may occur:

• Incorrect interpretation of code: Sometimes the diagnostic scanner may misinterpret the code or incorrectly determine the cause of the code. This may result in unnecessary component replacement or missing the real cause of the problem.
• Skip other faults: Code P1572 may be just part of a larger problem in the system. Missing other faults or problems in the electrical system or electro-hydraulic engine mount may result in an incomplete or incorrect diagnosis.
• Incorrect wiring check: Insufficiently checking the wiring or incorrectly locating a short may result in missing the real cause of the problem.
• Wrong decision: In some cases, mechanics may make the wrong decision and replace a component that is not actually causing the problem, which can lead to additional costs and time loss.
• Improper repair: Incorrect repairs or incorrect installation of new components may not only not correct the problem, but also create new malfunctions or damage to the system.

To avoid these errors, it is important to diagnose thoroughly, use the correct equipment, and follow the manufacturer's diagnostic and repair recommendations. If necessary, contact an experienced technician or an authorized service center.

How serious is the fault code? P1572?

Trouble code P1572 indicates problems with the right engine mount electro-hydraulic system, which affects vehicle stability and road handling. Although the immediate consequences of this malfunction may not be as severe as problems with the brake system or engine, for example, ignoring this problem can lead to additional damage and more serious problems with the vehicle's handling.

Symptoms associated with the P1572 code, such as vibrations, road instability, and decreased performance, can create dangerous driving situations, especially when turning or driving at high speeds. Additionally, if the problem is not corrected, it may cause further wear or damage to other chassis or engine components.

Therefore, although a P1572 code may not pose an immediate safety threat, it should be considered a serious problem that requires immediate attention and repair.

What repair will help eliminate the code? P1572?

Trouble code P1572 typically indicates problems with the right engine mount electro-hydraulic system, which provides engine support and vehicle stability. The following repairs may be required to resolve this issue:

1. Replacing the solenoid valve: If the problem is due to the malfunction of the solenoid valve in the electro-hydraulic system, it should be replaced. The solenoid valve controls the distribution of hydraulic pressure in the system and can cause unstable operation of the engine mount.
2. Repair or replacement of wiring: If the problem is due to a short circuit or break in the wiring, then conduct a thorough diagnosis of the wiring and replace the damaged sections. Proper wiring and wiring integrity are critical to proper operation of the electro-hydraulic system.
3. Checking and servicing other components: Check the condition and operation of other system components such as sensors, valves, pumps and relays. Finding and replacing any damaged or faulty components may help resolve the problem.
4. Programming or CalibrationNote: In some cases, the system may need to be programmed or calibrated using specialized hardware and software. This helps the system work correctly and efficiently.

If you are unsure of the cause of the problem or cannot carry out the repair yourself, it is recommended that you contact an experienced mechanic or an authorized service center. They can carry out more detailed diagnostics and professional repairs using specialized equipment.
