It is the high pressure fuel pump. My 3008 also same. One day, while in KD, engine fault came up. Sent car to KD SC and they only did an ECU reset. Car was ok for a while till my trip to Ipoh. Upon returning from Ipoh, engine fault came back and this time, car seriously underpowered. Can't go any faster than 90kph.

Went back to KD SC and found out I can't claim under Extended Warranty because previous owner (I was the 2nd owner) exceed last service by 40km. Appealed at Glenmarie and no avail. Finally, called up some friends and they recommended me Peug Auto in Glenmarie who replaced the high pressure fuel pump plus labor at RM 2k flat. No GST. Took the offer because car already down for nearly a month. If going there, look for Puru. Nice fella and formerly with Naza Peugeot. He shared many horror stories with Naza.

Since warranty over, I now service outside. More than 70% cheaper than Naza!

I had the same vibration when slowing down from 130kph. Turns out both front discs have warped.

I'm going to claim this RM 2K back from the used car dealer because he signed a black and white stating car still under warranty when I bought it. Always get a black and white confirmation from the user car dealer whenever u purchase anything with extended warranty.

Same problem as my 3008. OBD revealed O2 secondary faulty (the one after the cat).

I did for my 3008. So far so good. Sapu corner still stable.
