VelSatis cold start misfire

Alright lads, I'm pulling my hair out here! My 2002 Renault VelSatis with a gasoline engine is being a proper pain. It starts rough as anything when cold, misfires like crazy until it warms up. I'm thinking it's the cold start injector. Anyone else had this?

I had similar cold start problems with my Vel Satis. Has the fuel system been checked? Maybe try injector cleaning first before jumping to conclusions.

Cheers! Did cleaning the injectors sort it for you, or was it something more serious?

Unfortunately, cleaning didn't solve it for me. Eventually, I had to replace the injector. I would suggest getting it properly diagnosed at a workshop.

Right you are, it's booked in for a pro once-over. Cheers for the heads-up. Turns out it was indeed the injector! New one fitted and all good. Cost a bomb though, 515€!
