I have a 2005 LR3 with a suspension issue. The computer says pressure increases too slow when filling reservoir. I replaced the suspension compressor and it did not fix the issue. I found that there is no power to the compressor although all the relays and breakers are fine. I manually inflated the reservoir but the air shocks are still low. I think there must be a sensor somewhere that is defective. Any ideas? I am totally stumped, and I know this is not a unique problem. I am a newbie so be gentle

 

Did you read the codes yourself? If so your scanner might be able to tell you the pressure.

I replaced just the dryer on mine for the same error. But I think there were some
Leaks at the old dryer because the filters in it get plugged up with old silica.

After replacing the dryer, you could see the pressure building faster.

 

I read the codes myself. I have the tool but it did not specify dryer or anything else. Where is the dryer? is it on the compressor? Thank you so much

 

Yes, it's on the compressor. Was it a new compressor or a used one that you installed?

 

It was used, but there is No power to the compressor. it does not even run so there must be something (like a relay or pressure switch) that turns it on. No?

 

Does it never run? Or does it just shut down after the error message or warning light show up on the dash?
