It isn't the up-over-down passes that are the main problem especially in Chile and Argentina because there are no roads that stay at such high elevations for very long distances. Paso Jama and similar allow fairly high travel speeds and of course the engine is under a decent load on the way up so can maintain the DPF in satisfactory condition. Fuel quality in Chile and Argentina is also said to be better provided you buy from the main brand stations.
The high plains in Bolivia where you can spend days chugging along at 3500 metres, at low temperatures, sometimes running on lesser quality fuel are where you can get problems because if the vehicle gets to the point where a regen cycle is needed, it often can't be carried out because the operating conditions don't allow it. Even that isn't necessarily terminal, but if it is allowed to continue, the computer system might eventually give up and select limp mode.
