Citroën C5 2010 Diesel – Won’t Start After Driving, Even After Replacing Battery and Alternator. Please Help!
Hi everyone,
I own a 2010 Citroën C5 diesel, and I’ve been having a very frustrating starting problem. I’m hoping someone here has experienced something similar or knows what could be causing it.
Here are the symptoms:
● Sometimes the car starts perfectly fine, but other times it won’t start at all.
● When I try to start the car, I only hear a clicking sound, and the engine doesn’t crank.
● If I connect jumper cables to another battery or vehicle, the car usually starts again.
● After driving for a long distance, if I turn off the engine, the car sometimes refuses to start again.
● I’ve also noticed that the problem seems to happen more often when I park the car facing downhill.
● On some occasions, the engine has started but then stopped shortly afterward.
What I’ve already replaced:
● Brand-new battery.
● Brand-new alternator.
Unfortunately, replacing both parts hasn’t fixed the problem.
The strange thing is that the car can drive normally, but once I switch off the engine, it might not start again without a jump-start.
I’m wondering if the problem could be related to the starter motor, a bad ground connection, battery cables, an electrical fault, or something else.
My questions:
- Has anyone experienced this problem with a Citroën C5?
- Could a faulty starter motor cause these symptoms, even though jump-starting helps?
- Could it be a bad ground cable or another electrical connection?
- Why would the problem happen more often when the car is parked downhill?
- What should I check before spending more money replacing parts?
I would really appreciate any advice or suggestions. I’ve already spent money replacing the battery and alternator, and I don’t want to keep replacing parts without finding the actual problem.
Thanks in advance!
