Hi. 6 months ago I bought a c4 picasso 1.6 hdi. It turns out that the car had few issues.
I have changed egr valve, twice, maf sensor, twice, glow plugs and the map sensor. But after weeks of being with mechanic, he is unable to fix the hesitation on the car. It happens only under load or on incline. Car got pending code p0409, but it will disappear after engine restart.
Car is working fine when Maf sensor is unplugged. New sensor will not fix the hesitation.
I find a air leak close to air doeser. Got it fix (made a new gasket). But it made no change to the hesitation. I just running out of ideas what can be wrong with the engine.
Any advice will be appriciated.
Thanks
