M3 clutch slave cylinder
We offer the rebuild of the clutch slave cylinder for the E46 M3 SMG II. During the repair process, we replace the piston seal with one specifically engineered to endure the rigorous conditions within the SMG system. This seal is carefully crafted by a reputable German specialist company in collaboration with the manufacturer of the hydraulic oil. Additionally, if required, we utilize specialized tools to meticulously grind the inner wall of the cylinder, eliminating any score marks.
We offer two ways for the repair:

Way A: Direct overhaul of your part
In this case you send us your slave cylinder (to Germany) and we’ll refurbish it directly. Normally we finish the work and ship the part back within 24 hours.

Way B: Provision of a ready overhauled part
This service is only available under certain conditions. If on stock, we’ll ship a pre-overhauled and ready-to-use slave cylinder towards a deposit payment (core charge) of 300€. You can change the part in one single repair process and the downtime of the car stays minimal. After the change you have to return the old part to us within one month (counting from the day when our part arrives at your place until the day when you ship it back / hand it over to the courier). If you return the part later than one month, but within 6 months, we will refund 70% of the deposit amount (30% deduction). After 6 months we can no longer refund the deposit amount for legal reasons. The return shipment is your responsibility, the costs are to be covered by you. In general the part must be in a repairable condition, which means no damages besides the normal attrition during operating. Please mind: the deposit amount does not include the price of the repair – the amount is to be paid additionally.
