估计dpf堵了，看到halfords 提供所谓deep cleaning，大家用过没有。85块钱到不贵，不知道是不是就给我regen一下。
我google了一下：在moneysavingexpert上看到：
The car will regenerate the DPF just fine, all it needs is a 20 minute drive to reach good temperature, and a little bit of speed (say around 50mph to provide good exhaust flow and to increase engine load by increased aerodynamic drag). Lower speeds will also suffice, you just need to load the engine a little. And don’t redline the engine - redlining causes increases oil consumption, and the burnt oil eventually ends up in the DPF making things worse.
85块钱清洗一下还不贵？
楼主去用过了吗? 有用吗?
