75 diesel woes. Please help

Hi all. Ok I have a y reg 75 diesel conny that is in fact my dads. He lent it to a friend for about 18 months as long as he looked after it. However this has not been the case. It has just passed an mot last week apparently. If you can help with any of the following it would help a lot!



1. Abs warning light and brake pad warning light on. I'm hoping it's just a poor connection as the front drivers wheel arch liner is in the boot.



2. When the engine is running it's making all the lights flicker, including the dash lights. Also I have no dip beam, the main beam warning light doesn't work, nor does the indicator idiot lights or the audible clicker.



3. Fuel gauge doesn't work.



4. Central locking doesn't work.



5. There's a clunk on the front when braking while reversing, but I'm guessing it's droplink.



6. The climate control is showing 'err' on the display.





It has bloody annoyed me as there are more faults but I know how to fix them and it's obvious he's been using it for work as its full of brick dust and just general crud off building sites.



There will be more as this is what I've noted just driving the ba**ard home.



Thanks guys!
