I have the "C1A13-64 Pressure doe not decrease when venting gallery" error and have been told the air compressor needs changing. I was quoted around £800 for the job from a Land Rover specialist which I dont fancy paying as it works fine most of the time and I only get the error occasionally.

I've had a look on ebay and they are roughly £150. My local garge says he has changed a few in the past so I was thinking of just taking it to him.

Few questions. Does the 2010 have a AMK or Hitachi compressor?

Also does the the part have to be "coded in" or is it a simple switch with the new one?

Any other complications that could happen?

For £150.00 that will be a crap Chinese copy that won't last as long as it took to fit it. Pay the extra and buy a decent one.

Have a look under your car to check. My 2010 had a Hitachi and I replaced it with a Dunlop compressor as it's a straight swap.

Made in the UK and you can buy the part for £195 + VAT here: https://www.lrparts.net/lr023964-air-suspe...relay.html

30 mins to fit if everything goes well.

Don't buy a cheap unit from eBay, you will have no end of problems. Kev

Thanks for the link.

How do I know which of the two compressor's it is just by looking at it from under the car?

Also, before going out and buying a new compressor, you may want to consider checking and servicing the exhaust valve on your compressor first

You'll need to remove the plastic cover. Here's a picture of my old Hitachi, which should help you in identifying yours...

Strange really according to L/R Vin. AA000001 - BA708254 Hitachi fitted, BA708255 - CA725628 AMK fitted,
CA725269 - DA768669 reverted to Hitachi, then Vin. DA768700 on back to fitting AMK's. My car is in the range CA725269 - DA768669 and a MY13 and has the Hitachi fitted. Of course the above would not necessarily apply if the compressor has been changed previously.

AMK looks like this underneath.

mine was upgraded from Hitachi to AMK even though it was a 2006 car so defo shoulda been Hitachi.

I believe LR intially changed from Hitachi to AMK because there was a sourcing issue as a direct result of the Fukushima Daiichi disaster in Japan in 2011.

However, I'm not sure why they flip-flopped at a later date. I can only assume it must have been stock issues again. Kev

Had a look today. It's a Hitachi one.

Knwatkins, the link you sent says it is only 06-09 RRS. I'm guessing it will fit on a 2010 if it worked for you though so I'll go with that one.

Yes, they are the same part. Kev

Fitted today and goes up and down without errors now

However I have noticed it is a lot slower to raise the car now. It takes around 15-20 seconds between each stage. I saw the "Vehicle raising in progress" message after about 10 seconds which it has never done before

Well done for fitting and saving yourself a fortune. That does sound like a long time. Remember it may do this if you have raised the vehicle a few times over a short period. You need to give the compressor a bit of time to refill the air reservoir. Kev

You seem to have all the answers. That was the case as I pressed it a few times in a short period when testing. After leaving it for a few hours it works instantly now. I just need to adjust by brain to not expect to hear the error message "ding" when lowering the suspension.

Thanks for your help.

Great news

Glad to have been of help. Kev
