Claas error codes

[Sackofnuts]

Hi all.
Thinking of buying a Claas Arion 640 (2009) that we have seen but its showing these error codes.
Does any body know what they are and how serious they are:
Id7777h
Id76B5h
Id7781h
Id7F07h
Id765Dh
Obviously we will stay well clear if these are something serious.
Many thanks

Well 7777 is de rate, prob caused by 7781, not sure what is is though, 765DH I'm fairly sure is power boost sensor, not sure the on the others really. Is there any obvious issues with it?

Have only had a run up the road and back which isnt much of a test for it but all seems ok, theres nothing obvious

Id76B5h - Signal voltage on the left load sensor non valid.
Id7781h - Position of the egr еxhaust gas recycling valve non valid.
Id7F07h - Communication error between the WLP module and DBD - No message received from the WLP (a104) module for more than 5s.
Id765Dh - Claas power management function faulty due to loss of information from engine speed sensor .
Id7777h - Reduction of fuel input - probably in relation with the EGR problem.

7777 I think is fuel starvation , usually caused by the little plastic inline filter under the cab at the drivers door being blocked easy fix.
The boost sensor if your lucky it will just be the sensor which is behind the right hand front can mount ( pain to get to) if your unlucky the sensing wheel will
Have fallen off as it is only pressed on and is guilty of falling off and required tractor to be split to change it.

EGR valve will be siezed , common fault and you won’t get it out without breaking it.

Nothing too much to worry about blank egr pipe off and take pin out of motor will work normal then,power boost not end of world if it's done high hours it would be worth splitting to do damper plate do sensor dish whilst in there others electrical faults will be linked to a little module failed called the bridge that failing if it's cheap buy it lot of tractor for money normally

Thanks for the replies

Can anybody help, we’ve got a Claas Ares 567 coming up with error code 307 with no transmission.

I once sold an 14000hr JD6600 for a 2010 claas 640. (Fool)
That many error codes noone would use it except me.
I no longer have a claas...........
