Hi guys, new member from Adelaide here. I am sharing a Passat TDI 2.0 2009 with my son. We have 3 cars in the family and we take the one that fit the need. We have a MG HS that is a nice car but mainly use as classy, high view on the road, fantastic driving help and perfect for small shopping. The Passat Wagon is when we need a tow bar or we have long stuff for the back or the roof. Comfortable too, but very low for old people or people with leak knees or back like me 
. But appreciated by my wife as the seats are heating 
. And we got an old Getz that bring us from A to B but a manual one, so kids stay away from and 3rd gear is not locking and kicked out, we use 1-2-4 and 5 only, so not ideal when we need to go up a steer hill 
.
Here my issue : we got the driving belt that exploded. I installed a new one for him. After I restarted the engine, I headed under to replace the wheel and the plastics around it. I noticed some clear liquid leaking under. A drop every 5 seconds was going on the floor. I tried to find by odore what it was. It was looking like oily but clear liquid. I found that my secondary pump was leaking diesel fuel. That is likely the reason the belt get destroyed like that... I ordered a new secondary pump (Bosch) and after I installed it, I primed the two pumps by un-connecting the electrical connectors and powered the pumps directly with an external 12V. I ran both pumps for 30 seconds, three times. After that, I reconnected all electrical connectors and tried to crank the car but nothing... I do not have any VW computer (VCDS or VAC COM) to connect, just a small code reader. I checked with a multimeter that during cranking, no power was provided to either pump. I ran manually the secondary pump with my external 12V and let it run while I moved to crank the car and the engine started. It starts. I ran just a bit as I don't want to run dry as I was only using the fuel present in the filter (as the main fuel pump was not running). I check fuses and all seems OK, power arrive at fuse 28, only thing I have not been able to do is check the relay. Any tip to test the relays ? Or any explanation why the computer would not power the two pumps ? I just find strange both pumps are not powered... Any help ? I have someone that will come with a VW computer next week but if I can get that car back to my son, it will save us a lot of money
