Anti-pollution fault and ESP/ASR not functioning

[SAALAM]

I drove car today and the drive was very good, all the power was back and no engine management light or message on display.

After driving 126 miles 'Unblock Diesel Filer' message appears on display and engine management light is on. Then driving at 143 miles 'Antipolution Fault ' and 'ESP/ASR not functioning' message display on message and ESP light is on. Now the rpm is not going above 2600.

On way back home I drove around 273 miles and car power is too low and it drives too heavy.

Then I rescan car and it gives the following errors:

ABS or ESP ECU:

Intermittent fault. Communication with the engine management ECU fault. Incorrect value received.
