A6 Allroad 2007 sitting on bump stops showing codes 02646 & 00453

If anybody can give me details on the above codes would really appreciate it.

I have picked up a compressor repair kit from bagpipingandy but the guy who is going to fit it for ran the diagnostics & asked me to check the codes.

I ran a search of the threads but got nothing

Thanks for the reply Roy.
I have had problems with the air suspension for a while, being sluggish to get up to each level etc, that is why I bought bagpipingandy's kit thinking it would be the compressor piston ring that was worn so I am hoping that will cure the 02646 problem.
00453 is a worry, the car is an auto so this is a problem with the transmission fluid temp sensor??? or are we in to a code with a deeper meaning?

Just as a follow on from my original post.
The guys looking at the car have said that when it starts up they get a solenoid clicking in but the compressor does not run.
They have the compressor on the bench & give it a direct feed & it does run but it seems to be drawing high current.
They seem to think it is a control module of some description & want to send it on to a guy who deals in electrical problems only.

Anybody got an idea if these guys are on the right track or are they missing something?
They seem like good guys & are recommended by a couple of people we know so I am sure they are giving it their best shot.

Any advice would be greatly received.
