hi friend
The easiest place to find the VIN on your vehicle is right on the lower left corner of your dashboard. You should be able to read the number by looking through your windshield on the driver's side of your car. Check the driver's side door. The VIN might also belocated in the driver's side doorjamb or on the doorpost. I hope these images will help you.

Possibly the Heater Core is leaking. They are located on passenger side under the dash.

It is controlled through an electronic relay mounted in tailgate handle. If it has some rust then it doesn't close the circuit to release the lock. just clean the relay switch and it'll work (but to unmount this handle you'll need to open the gate first and then you'll access the switch by removing the plastic trim from inside the tailgate or better let it done by a mechanic or car electrician).

usually you should do it for peugeot diesel at 122000 miles along with water pump and the tensioner roller that runs under the cambelt too. But to be on the safe side do it at 100000 and save the fortune.
It took me (DIY job) about 6-8 hours as i wanted to save 450 pounds.

Sounds like a starter motor problem. Possibly a sticky solenoid. Try rocking the car or giving the starter and solenoid a hard bang with a hammer.
