About this product
Sourced from CEI, this repair set retarder (298.890) combines precision engineering with durable materials to meet the demands of everyday driving and extended service intervals. This part supersedes original equipment references: 21054210, 21666546, 298.890, 298890000 and 8 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.

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.
