That should make quite a difference.
Then I will clean out the inlet tract and throttle and get some injector cleaner in it.
Aparently the dpf won't regenerate if the engine doesn't get hot enough so I have no idea how long it's needed the thermostats doing so the dpf could need a regen plus the egr isn't working properly as it's too cold too.
Yep, this is true, 2 of my mates have 330Ds that had DPF lights on and both were cured with new 'stats.
Some conditions here..
Regeneration of particulate filter DDE5.0/ 6.0/ 6.2
To enable regeneration of the particulate filter, regeneration must be requested in the DDE control unit.
The regeneration is requested in that the consumed fuel since the last regeneration is set to a maximum value in the DDE control unit.
The regeneration is started at the next trip as soon as the coolant temperature has reached a value of at least 75 °C and the exhaust-gas temperature before cat. has reached a value of at least 240 °C. Moreover, the fuel level must be at least 10 litres.
The best possible effect of the regeneration is achieved if the vehicle is operated for around 20 minutes at a speed of at least 60 kph that is as constant as possible as of the start of the regeneration. Experience has shown that non-urban driving achieves the best regeneration results.
