the anti pollution fault is a very general fault on the peugeots and so u cant ever tell exactly what or where a problem is because of this error. however, luckily you mentioned the smoke. pay very close attention to the smoke and exactly which colour it is

Gray or blue smoke from the exhaust. You notice gray smoke coming from the exhaust when you start your car. The smoke may or may not disappear after the car is warmed. If it is, it is less noticeable. The smoke may have a bluish tint to it.

Possible causes:

1. The engine's piston rings may be worn.

The Fix: Replace piston rings. (Generally not a DIY job)

2. The engine's valve seals may be worn.

The Fix: Replace valve seals. (Generally not a DIY job)

3. Damaged or worn valve guides.

The Fix: Replace valve guides. (Not a DIY job)

Symptom: Engine uses more oil than normal, and there is some smoke from the exhaust. The oil level is low between oil changes. It appears that the oil is being burned by the engine because of the smoke in the exhaust. You may or may not notice the engine doesn't have the same power as it used to.

Possible causes:

1. The PCV system is not working properly.

The Fix: Replace PCV valve.

2. The engine may have mechanical problems.

The Fix: Check compression to determine engine condition.

3. The engine's piston rings may be worn.

The Fix: Replace piston rings. (Generally not a DIY job)

4. The engine's valve seals may be worn.

The Fix: Replace valve seals. (Generally not a DIY job)

White smoke or water vapor from the exhaust. You notice white smoke coming from the exhaust when you start your car. If it is cold out, this may be normal. If the smoke does not disappear after the car is warmed, you have a problem.

Possible causes:

1. Water/Coolant may be entering the intake manifold through vacuum modulator.

The Fix: Replace vacuum modulator

2. Cylinder head gasket(s) may be bad.

The Fix: Replace cylinder head gasket(s).

3. Cylinder head(s) may be warped or cracked.

The Fix: Resurface or replace cylinder heads. (Resurfacing is not a DIY job)

4. The engine block may be cracked.
