Faulty relay - advice needed

Hi Guys - took the Disco into the local dealer this morning to get some faults seen to. Every morning when I start the car or anytime where it has stood for a while you get fault messages up on the display - faults seen so far are EPB, HDC, Tranmission and Air suspension & compressor overheating - The dealer has informed me that these are ALL caused by 1 faulty relay - has anybody come accross this before and can anybody confirm that all these controls actually do run off one relay?
I don't have any or the cars books here so I don't know if the dealer is feeding me BS or not? They also inform me that they have used the rear demisters relay as a stand in as there is a 2 week lead time from the uk for these relays and they don't carry spares - are they so "special" and non standard?

My first thought would be check the battery voltage before starting the car and also as soon as it starts . You'll be amazed at what faults show because of low voltage

I asked them to check it as that was my first thought as well but they reported that all was ok? Will swap the batt out with another to see if it makes a difference if the problem persists?

It seems that the D3 is very suseptible (sp?) to any type of electrical funny . I bought the wrong led replacements for my brakelights ,and had just about every type of light and warning going off the moment I used the brakes with the lights on (including the suspension lowering) . Put the old bulbs back and everything was OK

Heine - looks like the battery was also a problem - they are replacing it under warranty excepting they don't have stock!
