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 […]

This article analyzes common error codes, like 57 (0x39), on the E46 SMG pump due to the pump’s inability to generate proper system pressure. The SMG pump usually activates to create a specific pressure range, most noticeable when the vehicle has been idle for a lengthy period. The majority of this fluid pressure is retained […]

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:
