C5 2011 Diesel engine vibrating and lumpy.

Unread post by belaprops »

Hi All.

I looked around and read as many post as possible but am still wondering why my great C5 VTR PLUS NAV HDI 160 engine is so vibrating and feels like it's not running as smooth as it should.
I also has a problem with going from 1st to 2nd gear and the best time is to do it around 1500 rpm which is usually just under speed for 2nd gear. The gear stick resist going and I have to pull hard to go to second. Going to 3rd sometimes grinds before going in but there is no resistance just as when going from 1st to 2nd. Shifting down is smooth.
My mechanic suggested to bleed the hydraulic system to make sure the clutch gets full pressure to disengage.
I'm wondering if the lumpy engine and the vibration of the engine is related to the gear problems I have.
I'm not an car mechanic but have a good grasp of technical aspects.
Reading that it could be injector related I put Redex with a full tank of diesel.
It's a great car if I can only sort this engine challenge....I can live with the sat nav as card missing :-D
I look forward to your advice and experience with this great car.

Something could be wrong with the clutch hydraulic system so i'd check that first. But it probably is something with the clutch or gearbox.
How many miles are on it?
I have various repair handbooks and wiring diagrams for C5 mk1, Xantia, XM, Berlingo and C3 mk1.
I have Lexia/Diagbox (Sweden) and Servicebox/sedre
