Frequently asked questions

What is the ERR5041 oil filler cap for?

The ERR5041 oil filler cap seals the engine oil filler neck on the rocker cover of the 2.5L 200TDi and 300TDi engines. It keeps the lubrication system sealed against dirt and moisture while allowing the engine oil to be topped up.

Will the yellow filler cap fit both 200TDi and 300TDi?

Yes, the ERR5041 fits both the 2.5L 200TDi and 300TDi engines on the Defender (1987-2006), Discovery 1 and Range Rover Classic. The cap screws onto the rocker cover filler neck and is shared across these Tdi applications, so the same part covers both engine generations.

Should the filler cap be replaced if it's leaking?

Replace the oil filler cap if its seal is hard, cracked or no longer sealing, as a worn cap typically lets oil mist escape from the rocker cover on a 200TDi or 300TDi. The ERR5041 is a sealed screw cap, so a perished seal usually means fitting a new cap.
