Hello, I could use some help with theses codes. I have a 2000 Disco with 220000 miles. Theses codes recently popped up and I'm now getting over 100 miles less to a tank of gas.

Looks like it's the Evap and or purg valve. I took it to a reputable mechanic but they couldn't tell me what needs to be replaced. Anyone have these same codes/issues?

Sure could use some expertise!

Thanks in advance...

 

Fortunately have not encountered the code myself and never worked on the system. I would take a look at the Workshop Manual to learn about the system and get a better understanding of what a code might indicate.

If you don't have the manual:
You can go here:

Click and Save link that looks like this:
Land Rover Rave Service Manual large file warning 590MB Takes awhile to download.
PDF "rave-lr" in zip is probably all you need. Move to a convenient location on drive. Open Rave & click on vehicle type for manuals you desire.

Then you'll be able to find stuff like in the attachment that may help is applicable to your vehicle.

That's easy. Replace your gas cap with a new one and reset the code. If the code comes back replace the purge valve canister with a unit from rock auto. Prices range from $30-$300 so trust me when I say to order this piece from rock auto. Compare the price to atlantic british or rovers north
