Anyone been inside a Webasto 2000 recently?

[pcatterall]

i have a strange Webasto on my bench. it is the diagnosis model but inside there are 2 motherboards rather than the usual one. The normal one is there but hidden underneath the hinged part is another board. my electronic knowledge is pretty poor so i cant work out what it does. has anyone seen this set up? The only othe rdifference seems to be that there is only one pump lead exiting the terminal on the motherboard rather than the usual pair.
Ideas/speculation welcome!!

I noted the numbers on my Webasto heater and sent away to the distributor who kindly sent me the english pages from the manual.... perhaps Webasto would send you some info... I'm not sure if it would have the detail you might require, but worth a try ?
