| Fault C1A20 only when loaded |
|
When I load up the truck with 6-7 passengers or a load from the DIY store, I get the suspension fault C1A20. No fault during normal driving without the weight.
06 D3 HSE with 152k miles on the clock. Rebuilt the Hitachi compressor & drier with a kit a couple of months ago to fix overheating/blowing fuses. Rebuild fixed that, now rising to slowly under load.
Wondering if rear valve block is toast?
