Thanks guys. I've lost faith on Peugeot SC at PJ as when I get engine fault, they changed all spark plug and ignition coil in June 2019. But just right up after i picked up the car from that service, engine fault message came again and had to tow the car again.

Apparently the spark plug replacement was touching that caused error and they took courtesy to come my house to change the spark plug (only). Now same engine fault message pop up again and found that ignition coil is faulty again in October 2019 (just after 4 months replaced that damn thing). Probably ignition coil gone bad after that spark plug was touching previously.

Can anyone help to share maintenance schedule list for 408 2.0?

Is there any 408 2.0 user has common problem with catalytic converter?

I've got engine repair fault warning after 40 mins driving on highway but no jerking or whatsover. Sent to Renautech and found faulty on this catalytic converter. Got 3 options; clean it (but no guarantee it will last), replace it (will cost more than 2k) or shut down it's system (doesn't affect car performance as it only to detech for environmental purpose as regulated in Europe but don't think applies in Malaysia)

Did asked if doing Decarbo would help but they told it's actually not related.

First time I experience car battery blown out when I started the car. Crazy. The battery has been 2 years and 9 months. The brand is panasonic DIN62L that I changed at SC PJ.
