Frequently asked questions

What does the ERR4621 Injector Sealing Washer do?

The ERR4621 seats at the base of each fuel injector where it enters the cylinder head on 200TDi and 300TDi engines, creating a combustion-gas seal around the injector bore. A failed washer allows blow-by at the injector seat, causing hard starting and power loss.

How many ERR4621 washers are needed per engine?

One washer is required per injector — four per engine on the four-cylinder 200TDi and 300TDi. Replace the full set whenever injectors are removed for service or testing; reusing disturbed washers risks combustion blow-by.

Does the ERR4621 fit the Freelander 1 diesel?

Yes — the ERR4621 fits the Freelander 1 (1996–2006) with the 2.0L TCIE diesel engine. It is the same injector washer used on the 200TDi and 300TDi in Defender, Discovery 1, and Range Rover Classic from VIN JA610294.
