 Hi has anyone upgraded the Xenon bulbs and ballasts from 25w to 35w to improve the light output?
Can these run better LED H7 mains and H11 fogs without throwing up a bulb warning too?

 Are the C4 Picasso H7 Hi/Low beam bulbs or just regular H7 Bulbs ?

I'm about to pull the trigger on some Hi/Low LEDs but thought I'd ask first

 If you are asking whether they are single or two filament bulbs, the answer is that the outer dip bulbs are single, the inner main beams are single as well. They both appear to be H7s. I have never had to change one in this. Never had to change a main beam bulb though. current car, but my previous one used to go through dip beam bulbs very rapidly

There's no such thing as a dual filament H7. H1, H3, H7, H11, HB3, and HB4 bulbs are single filament. H4 are dual filament.

 Are there any instructions on how to change the H11 fog light bulbs on the 2015 C4 Picasso?

Manual is useless and every video on YouTube is up to 2010 and below....

 To change foglight bulb you pull the grill cover off and undo the torx screws and pull the whole unit out.

 I was on about upgrading the optional xenon bulbs over the standard halogens.

 Hi. Yes ive made the upgrade 12 months ago, and like it very much. 35w 5500K, and with Philips H7 Ultinon X-treme LED bulbs in the supportive mains. It took a couple of months for the bulbs to reach their 5500K colour.
For fog ive got a complete new unit, because I wanted a correct cutoff.

 Oh, and no bulb out warning. Also changed the rear indicators with some powerful LEDs aswell. And some Philips X-treme vision w5w 6000K for the license plate.
