A couple of niggling faults. The steering seems to have developed a sloppy and loose feeling, like there is too much play in it. The dealer has checked all the geometry, but they say it is OK.
However the brake discs were replaced, due to juddering and the steering was fine again for about 4 days, until it returned to feeling loose and sloppy again, coincidentally the brakes are beginning to judder again slightly.
Great looks, superb economy with good power, 92hp unit is slightly slow pulling away (110hp probably the optimum balance of power and economy), but plenty of pull from 2nd gear upwards.
The engine is one of the best diesel units available, with no faults. However the only thing that lets Citroen down of late is the dealer's ability or willingness to repair faults when a car is under warranty. If a fault is not "out of a textbook" they have difficulty diagnosing it.
I have recently purchased a C4 VTR, only after 2000 miles the steering has started a random feeling when turning corners, seems like a slight grinding that runs right up the steering column, as if the road texture is being absorbed all the way to the steering wheel, but it happens randomly and on very smooth surfaces aswell, not sure if this is the same issue you have had, or if I am imagining it. Feels like the column is not secured, but the steering is still accurate and direct. Haven't told the dealer cause I am not sure how to explain it properly, but otherwise the vehicle is an excellent car to drive and highly recommended.
I have had the steering repaired twice on my car. Wheels were balanced, tracking reset and brake discs replaced for the third time. Once again, the car is perfect for about 300 miles, before the sloppy steering returns gradually. It is as if there is no resistance to any imperfections in the road, and the steering wheel wobbles around on bumps.
Incidentally the car was taken to Citroen UK in Slough, who apparently drove it for less than a mile and dismissed the case. The mechanic at my local dealer subsequently found 5 faults.
I work for citroen and have had a couple of c4s with track rod ends worn lately which would give you a sort of loose feeling another symptom would be noises when driving over bumps. hope thats helpful
