About this product
The CEI Differential Gear (199.101) is a professional-grade replacement component engineered for long service life and reliable operation across all conditions your vehicle encounters. This part supersedes original equipment references: 199.101, 199101000, 346 350 6623, 3463506623 and 7 more. Matching these numbers confirms a like-for-like replacement with no loss of function. CEI is a recognised supplier of automotive replacement components to independent workshops and dealer networks across Europe. All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops. If fitment or specifications do not match your vehicle, our technical team can help identify the correct alternative — use the vehicle selector or contact us with your VIN for a guaranteed-fit recommendation. Replacing worn components on schedule preserves your vehicle's safety, reliability, and resale value — and aftermarket parts from established brands deliver OEM-equivalent performance at a fraction of the dealer price. Every part is dispatched from our UK warehouse with a 30-day money-back guarantee and free hassle-free returns.
