C4 VTR, lots of problems; brakes, cracked windscreen, by itself, wiring to the brake lights broke of in roof, ESP, poor performance and lag when pull away. No good dealers. Ventilation system broke down and got stuck on heating mode.
Seems that this car was never tested, and is a danger to consumers, Recomennd that Citroen refund owners because this is a ripoff and a danger to drive.

So you changed the Citroen for a Suzuki diesel?
Did you know you've changed one motor unit for the same again? Suzuki use Citroen/Peugeot (shared technology).
I got the same problem. I have a 1.6 VTR+ diesel, and have had that pollution problem about 6 times now. Surely they need to sort the problem out, as I read these comments, and find I am not the only one having this problem with my Citroen. It has just happened again after only being in with the dealer 2 months ago for the same reason.
Did you get the ECU unit changed? If so, did this solve the problem?
I have had my car now for six weeks MOT'd when purchased, and the garage said it almost failed emissions and should come in for further testing. Booked it in at the garage, and they replaced the coil pack. The car then occasionally started to lose power, especially in lower gears, and the anti pollution fault and warning light appeared. The light is practically on all the time now, with the car randomly losing power. Should I take to the local garage, or is it a job for the dealer?

I had the depollution warning, put Redex in the fuel tank and the warning goes. 12 months now with no problems.
I got a C4 reg 04 with 6000 miles on it. The pollution light came on after about 11000 miles. I took it to my garage, and they changed a sensor in the sump, and that has cured the problem.
I have the problem, where under 5C, it has a real problem starting; it can take 2 to 3 minutes. It also started blowing a fuse every so often; that stopped it starting. Replacing the starter motor cured this.
It has also had a new gear box.
At the moment it has done 46700 miles. The dipped head light bulbs keep blowing as well.
I did have a 4 year AA cover on it; that has just ended
My Citroen C4 1.6 VTR 2006 has the same 'anti-pollution faulty' sign appearing every time I start the car, and now it won't start at all. It's all too embarrassing, considering I have it serviced at all intervals as per the manual.
Citroen C4 Grand Picasso, petrol. De-pollution system warning light keeps coming on, and then occasionally a warning about the electronic handbrake. If that happens, then it loses power and stops. Usually stopping the engine and restarting resolves the problem. I am convinced this is a problem with the sensors, but I am sure Citroen will love replacing one thing after another. They genuinely don't seem to know what to do. I think it's a bit of a disgrace.
Citroen C4 1.4i VTR 2005.
I had the anti-pollution/check engine warning light on with engine cut off or not igniting. Changed a coil, but it keeps having the warning on. My engineer checked my fuel pump pressure, checked the fuel sensor, and checked the electrical installation of the engine, but found nothing wrong.

I understand the frustration that Citroen owners feel towards the dealers in solving their problems, like myself, but I won't be as critical of the vehicle itself.
Bought the vehicle with 80,000 km, and the first winter with temperatures < 5 degrees C, the engine battled to idle and the engine light came on (anti-pollution faulty). Dealership at first could not find the problem. Third time they said the MAP sensor (manifold absolute pressure) is faulty. Replaced the sensor and cleaned the throttle body. Problem disappeared for 2 years.
Then the idling problem started again, but this time the engine lost revs while driving and dies in traffic. Also the idling problem became a big problem after a long distance trip. Did not want to idle without giving it some gas. First action was to clean the MAP sensor (no replacement) and the problem improved 60% (not cutting out in traffic that often, but idling after long distance was still a problem). Then cleaned the throttle body with carburetor cleaner and the problem seemed to be solved. KM were at 170,000 and going strong. Had the vehicle on the dyno machine at this km, and the engine performance graphs were as good as a new engine.
My advice would be have the MAP sensor cleaned once a year and the throttle body every 18 to 24 months or about 50,000 km. Both minor jobs that can be done in 90 minutes only with carburetor cleaner (the throttle body sits between the air filter and engine block). Also, don't fill up at dodgy filling stations, and use the best fuel and engine oil.
Oxygen sensors can give problems over 150,000 km, so have them checked.
Fuel delivery can be a problem, if the filter, which forms part of the fuel pump, is blocked. If the engine gives off a rotten egg odor, it means that the EGR valve or line is blocked. With these types of problems, it is better to consult an auto performance clinic (not the dealership) because they are better equipped to troubleshoot the issue.

Remove your catalytic converter and get a pipe welded; it is amazing.
Just bought a C4 Grand Picasso 1.6 HDI. Have drove 32 miles since I picked up the car, and whilst doing 70mph on the motorway, I heard a thump, then a dramatic loss of power. The car struggles to climb up any gradient, but it sometimes feels like the car has power, then a loss of power. Reading on here, I'm thinking it could be linked to the turbo?
There are no warning lights on dash, so I'm confused. Any help? The car is going back to the garage tomorrow!
Update on the previous post - drove the car to the garage. About 6 miles before arriving at the garage, several warning lights came on; hand brake, ESP fault, anti pollution fault, along with the service light. The garage has informed me that the car has to go to a Citroen dealer to be checked for an unknown fault!
Also, it has been mentioned that car has been fitted with a new turbo.
Has anyone had similar issues?
C4 Picasso 1.6 HDI VTR 09 plate with 47500 miles.
Lost power and low oil pressure warning light came on, service stop lights came on, so then got towed to the garage. Oil pressure checked and returned to normal, oil and filter changed, oil strainer cleaned and replaced, and a new turbo and oil feed pipes fitted, big expense so far...
Now told sorry sir, you need a new engine as it is knocking! When asked why, was told it was due to having low oil pressure.
I am now confused, annoyed and angry. Imagine my horror, now it's second opinion time. Paid for the work carried out and towed away again.
Anyone had similar issues? Any comments appreciated.
Hi there, I live in Johannesburg. I have the exact same car and the exact same problem, except mine does not cut off when I step on the clutch. Kindly assist me on how you went about with cleaning the butterfly, where exactly is it situated etc? Thanks.
Air pollution failure... It's happened to me. The engine just cutout. I need a new fuse I'm told!!! Not happy.
