The Pentosin CHF11S hydraulic fluid is among the top options available for your system. It is advisable to use this particular fluid as finding a cost-effective substitute is challenging. Some customers have reported issues when using a fluid that primes faster, especially during low ambient temperatures. The issues typically disappear once the vehicle is warmed […]
Pressure accumulator failure generally occurs when the gas chamber section deteriorates, allowing pre-charge gases to infiltrate the fluid portion. This results in insufficient back-pressure for the system to function optimally. Accumulator failure is frequently caused by: Bladder accumulators are generally more prone to failure than piston types, often due to the flexing of the bladder […]
The E46 SMG pump systems incorporate a fluid reservoir designed to accommodate the additional fluid capacity required for the pump to achieve full pressurization. The reservoir is integrated into the intake air-box in all models except the CSL version. In the CSL model, the reservoir is a standalone component, attached to the shock tower. It’s […]
This article addresses the common E46 SMG pump Code 53 (0x35) typically resulting from the pump’s inability to generate the correct system pressure. The error code 53 (0x35), indicating a low-pressure level, typically appears when the pressure sensor signal shows that the system pressure is insufficient, and it fails to return to the normal range […]
The following description outlines the procedure for bleeding the clutch slave cylinder of E36 M3 models equipped with an SMG transmission. This process is crucial when replacing the SMG pump or servicing the SMG system, as it can help prevent the introduction of air into the system. Procedure:
This article investigates common error codes associated with the E46 SMG pump due to its inability to generate the correct system pressure. The error code, 56 (0x38), indicates the switching-on time of the hydraulic unit. Typically, the SMG pump is activated to prime the system until it reaches a specific pressure window. This usually happens […]
This article investigates a frequently occurring Error Code 55 (0x37) on the E46 SMG pump, which results from the pump’s inability to maintain the required system pressure. The SMG pump usually activates to establish a specific pressure range, primarily noticeable when the vehicle has been stationary for a while. The pump primes the system upon […]
The BMW E46 M3 can refuse to start for various reasons, including a dead battery, worn-out starter, or faulty brake pedal switch. However, sometimes, the issue may originate from the SMG Pump Assembly. Understanding the BMW SMG Transmission The BMW’s SMG transmission is a hybrid between a traditional manual and automatic transmission. It features a […]
The Porsche 997, 991, Cayman, and Boxster models with PDK transmission often experience a significant fault that can temporarily disable the transmission. This fault, which involves the distance and speed sensors integral to the PDK transmission, can lead to costly repairs and inconvenience for Porsche owners. The PDK transmission utilizes these sensors to gather speed […]
