Thread: Codes U0421 & C1A13

I have been researching a suspension fault on my RRS 10. While there was a long list of fault codes these 2 seem to point to a suspension pump problem. Popping up a warning. It is random but seems to come on at slower speeds.

I have only owned the car a few weeks so new to tracking down faults from codes. I need to identify which pump is fitted so will remove the cover and check tomorrow. Any help to identify which pump is fitted would be appreciated.

Also if I am wrong and these codes don't indicate the pump is crook would appreciate being pointed in the right direction.

Thanks in advance.

A quick search for the fault code descriptions suggests that the dryer might be blocked. This usually occurs when the desiccant becomes pulverised which then blocks the filter in the canister attached to the compressor.
