[babulasi]

Hi, I have a problem with my DS 5 2.0 blueHDI...so yesterday I go from work and sudenly a warning come up with message ENGINE REPAIR NEEDED, the car is running as normal, no lose of power, no check emgine light...I check with Torque PRO for faults and did t show any...what the heck is going on?!

Very likely some emissions related issue, but it really needs Diagbox to check for any faults as not all after-market scanners can read everything.

Is this a Hybrid model?

No, it is 2.0 hdi 180hp, automatic gearbox...it happen after I stop, start/stop system was on and after I released the pedal from brake, engine start and the message pop in

Ok, so I have heard that the alternator belt can be a cause for this - and as you mentioned it came up about the time of the engine re-start, it may be worth investigating here...

you think the belt has stretched and is slipping? I'll check it out anyway, thank you so much for the useful information

[GiveMeABreak]

It's just a possibility, but without a fault diagnosis, it's hard to say. I just mentioned this as it has been known with Stop Start systems and this message when restarting.

I understand... I'll check the belt, and if everything is fine there, the next thing is the battery... Of course, I'll also run a diagnostic check at the service center along the way

Is this a reversible alternator system?

[babulasi]

I think it is...I check voltage while running, it is 14v, so that's not the problem... :/

No but the belt and accompanying pulleys, etc need to be in top condition.
