Lot 5186: 1969 Citroen DS21 Luxe Station Wagon

Based on my research and analysis of this 1969 Citroën DS21 Luxe Station Wagon, here are the most common maintenance issues owners typically encounter:

1. Hydropneumatic Suspension System Issues - The signature hydraulic suspension is prone to leaks, particularly in the spheres (accumulators), height correctors, and pump. The system requires regular LHM fluid changes and proper bleeding. Common symptoms include sagging suspension, jerky movement, or failure to rise to proper height.

2. Electrical System Problems - As noted in this listing (non-functioning headlights, tail lights, horn, and clock), electrical gremlins are common. Issues include corroded fuse boxes, faulty headlight relays, and alternator charging problems. The 6-volt system (if not converted) is particularly troublesome.

3. Rocker Panel and Structural Rust - This listing specifically mentions “invasive rusted areas on the rockers, causing some concern for structural stability.” This is a well-known weak point on DS wagons, often requiring extensive metalwork.

4. Carburetor and Fuel System Issues - The Solex carburetors used on DS21s are notorious for diaphragm failures and require frequent tuning. Fuel pump issues and clogged filters are also common.

5. Manual Transmission Synchronizer Wear - The 4-speed manual transmission often develops worn synchronizers, particularly on 2nd and 3rd gears, making shifting difficult when cold.

The hydropneumatic system requires the most attention - plan on rebuilding spheres every 3-5 years and checking hydraulic fluid levels monthly. Many owners convert to 12-volt electrical systems to improve reliability. Regular rust prevention is crucial, especially in the rocker panels and front frame rails.
