Started the BX up today and the back end went up but the nose stayed down. Lowered the lever inside the car the put it back to drive position and all ok?
Seen this problem before but cant for the life of me remember why.
Nose down
The diagnosis is simple - the cure is not quite so. Its the front height corrector or its linkage which is at fault - and greasing and otherwise lubricating it will probably cure it.
Messy job - things like brushes, spray grease etc may help. I'm sure you don't need me to remind you to make sure there is room for you under the car with the suspension dropped.

Last time I struck this problem, someone ( a Citroen specialist) had been stuffing around with the rods that control the height correctors front and rear.
They have to be set at 7mm and 5mm respectively clearance from the end of the slot the arm sits in IIRC and these were set incorrectly, as a result, the arm hit the end of the slot and depressurised (for the want of a better word) the front HC which resulted in it sitting on its guts and not wanting to move when started unless you got out and shook the $hitter out of the front of the car which then seemed to wake up the H/C and make things happen.
I found by sitting the car up on ramps and resetting it, including moving the H/C arm around, I released the sticky arm which made it all work better anyway, but as soon as I reset this adjustment arm, it behaved itself.
A word of warning though; if you don't do this on a hoist, a set of ramps or over a pit then just be certain the your "affairs are in order" before you start because chances are you'll do yourself in when you free up the H/C and the car falls on you without warning. Things move fast on these things when they start to.

By the time you're old enough to know it all, you can't remember why you were learning.

No ones played under my car since I had it so I can just assume needs a bit of lub, thinking about some of the mud on my sills at the front because of lack mudflaps. That stuff set like concreate and will need a good run in the wet to loosen. This may or may not have resulted in this one off so far failure?
Good reminder about safety yes the BX is notorious for sitting on its mechanics.

Oooooooo pardon! (sorry)mountainmanUK wrote:everything moves better with decent lubrication!
Mine had the opposite problem when it came back from the garage last time, the arse was up in the air! Higher than normal driving level even when the lever was on its lowest setting. Moving the adjuster did the trick.
Did not notice until getting off the drive way which has a slight ramp to it. Then heard scrap as the exhaust system hit the deck
