This also implies that the R18 only has one particulate filter. That might be the reason why the Audi is smoking a bit more than the Peugeot.
I wonder whether the ACO will react to extensive smoke of the R18. It was very clear on the Sebring test video and there are reports that it was also visible during the Le Mans test day. Last year the ACO did not care:

Clearly, it does not help for the Audi's "TDI clean diesel" marketing campaign.
