Audi Q7 air suspension valve
Hi hopefully you can help in some way.
Recently my Audi Q7 gave the orange suspension light. It stays there permanently and doesn’t go away. Had a diagnostic check done and it has come up with a errror code which is below : -
Error code listed : 00145 REAR RIGHT ADJUSTMENT VALVE (M339) ELECTRICAL PROBLEM ON CIRCUIT.
above is the error code. The mechanic says it's a valve block. I don't really know what it looks like or what a valve block is. Could anyone please advise me what that means ?
Thanks in advance

The valve blocks are normally very reliable but it is under the floor about level with the front seats on the right hand side. There is a long plastic cover to remove to gain access.
With VAG-COM you can test each valve to verify the fault.
I would just get hold of a used valve block - they are not too expensive and only takes about 20 minutes to swap over.

thanks will try the above hopefully get it sorted. When you say used do you mean from scrappers? I can only find the aftermarket ones on net.
Thanks

Audi q7 air suspension
After two years i have replaced the valve block. Suspension seems fine but now i am given a new fault code
DTC code 00139 left front chassis acceleration sensor
open or short to ground.
The orange suspension light is still on and not flashing just static.
Please suggest what to do ive google to se what parts come up ... stuff like air suspension struts come up for over £500
Or a sensor with a wire for around 12.50
Im confused

thats a nonsense OBD2 P code, it wont help you at all here.. needs to get scanned with an VW/Audi specific tool, like VAG-COM/VCDS or OBDEleven.

Ok sir ive ordered obdeleven for this. Another question pal is ive installed led lights on to rear they keep flickering. Im an amateur but does that mean they need coding. All i did was got the lights and just plugged them in. Then got stopped by cops one day while driving cos they thought i was flashing them but then realised that they were constantly flickering lol.
Any help would be appreciated. Im just waiting on the obdeleven device to come and hopefully i can fix stuff myself.

Hi pal, hope u had a good christmas and happy new year. Hope u r all well,
So I got my obdeleven, got to work with the diagnostics. Basically despite replacing valve block both codes still come up. The log is below. Tested pipes could find no leaks. Now what i suspect it may be is after researching using the app is that i might need to replace "Left front chassis acceleration sensor". However im confused as i dont really know what sensor im after. I typed in the problem into google, some links bring me up to an air strut which is around £500 and some bring me to a sensor for about £20. so i dont know what to do. I did get a mechanic to do some testing though, he basically said he took the abs sensors off to see what difference that would make but he didn't test any further. His idea was that wires may be messed up. Ive never tampered with them so i dont really understand why he would say that but in the end said if it is wires he aint the man for the job. so can you guide me please. The log below shows more codes but only two remained after i deleted them. The two being 00145 - right rear dampening adjustment valve and 00139 - left front chassis acceleration sensor.
