Well, I went to pick the car up yesterday. I did explained what was written above about the tension, as best I could, the people there do not speak English and my technical Polish is pretty crappy. I was assured that all should be good now. So I got in the car and started it. It started in the EV mode, so I turn the knob to the 4-WD. It squealed like a pig, as the belt slipped. The mechanic came over right away stating that no such thing happened to him and he drove the car home and to work to make sure and verify all is well. He stated that the tension was right and that he thinks that the battery must be bad and needs replacement. He tried to explained that with battery not holding a full charge, the car upon starting encounters high load and that is why the belt slips, squeals and ultimately breaks. Obviously I left the car with him to "fix" the problem, although I feel like the explanation is kind of lame. I read number of forums where people have the problem with breaking belt on a hybrids, no one however has posted a real solution. Peugeot also has no mention of these issues either.
It is frustrating, as I like the diesel hybrid, almost as much as my Prius.
Hi, sorry to hear your troubles.
My car I had all the issues with is the 3008 Hybrid4 2012. It has two ways of starting! Turn ignition on, turn eco mode off, turn key to start position and engine starts using 12 volt battery and conventional starter motor.
When it starts in hybrid mode (eco in normal position) the alternator turns the engine using the 200 volt battery pack. I found that with "normal" tension in the belt, the tensioner assembly twists so far that it effectively locks on to the belt and the belt snaps. When I say snaps:
If your belts look like this, this is not wear, something is putting a hell of a lot tension over a very short time on the belt. For me, it was not tensioned tight enough when I fitted it!
I think you will find there is no 12 volt alternator charge to the 12 volt battery, it is charged via a power pack that runs off the 200 volt battery. The alternator power leads go directly to the rear of the car.
With no alternator belt fitted, starting it in eco mode and leaving selector in auto; the batteries, 12 and 200 volt will charge when the regeneration kicks in ( eg. going down hill)
Good luck with this. but make sure your garage uses the
frequency method to tension the belt.
