Kangoo – Built 01/2008 – 1,5 dci – 230 000km – Starts with start aid, but goes out immediately

Hello, since I founded a cleaning company, I need a vehicle like the Kangoo Rapid Diesel. Since the saved money has flown into the company, it had to be as cheap as possible. I have a Kangoo 1.5 dci Rapid or Express? down from 110€ to 850€. Previous owner he said he bought everything new: AGR, glow plugs, battery. The money I give him is so why only for the parts he bought. 1.Vehicle starts with starter spray briefly, but goes out again immediately. 2.On the brake pedal are soldered small wires of a cable, see photo 3. Error with mobile phone and torque read out. An error P0670 4. On the cockpit remains battery light and stop light. 5. Oil measuring rod despite refilling of 3 liters of oil no oil can be detected. 6. I can not find these two black relays. At the start try it sounds as if it would spark once at every turn. I have read something already, I believe if it starts with start help spray, is what’s wrong with the diesel injection. I have the car in the garden, so not in the workshop.
