Peugeot 207 Starting Issue

I'm at my wit's end with my 2015 Peugeot 207, gasoline engine. It just won't start sometimes! The engine refuses to turn over, particularly when in 'Park'. The check engine light is constantly on, and the gearbox feels jerky when it works – unclean shifting. My cheap OBD reader is showing some transmission error. Has anyone experienced anything similar? It's done 118409 km.

Sounds rough. Does it happen if you jiggle the gear shifter in park or neutral? Could be a faulty sensor or bad connection on the gear linkage. Does the engine crank at all, or is it completely dead?

Thanks for your quick reply! I tried wiggling the gear shifter, even slamming into Park sometimes, but no luck. Sometimes it starts after a few tries and weird noises, sometimes it just stays stubbornly dead. And no, the engine doesn't crank at all when it refuses to start.

Okay, if it's not cranking at all and the check engine light is on alongside jerky shifting, chances are that the control unit that manages the automatic transmission is indeed faulty. I'd suggest taking it to a reputable workshop for a proper diagnostic. Unfortunately that's not a cheap fix.

Thanks. I took your advice and went to the shop. Turns out you nailed it! Their diagnostics pointed to a defective control unit as well. They quoted me around 1000€ for the repair. Ouch! But at least now I know what needs to be done. Thanks a lot, again!
