So finally I got time to change the AC pressure switch which located at the bottom of condenser, And booked a ac refrigerant fill session with Alex Crow stowmarket. Fault code B107A15, Phenomenon,Fan is on, and spinning fast even when engine is cold.
For Alex, I wish I could have booked the MOT and service there, instead of AUTOKARE Cambridge. But 0w30 still sit at the right place in the measurement, after 700 mils.

For this thread ,I would like to discuess the Aftermarket filter which I purchased online. I bought them along with pressure switch, and I thought the price discount is good. The Mann filter used in the car CUK29005, cost similar.

When I took the previous filter out, I realise that each penny is worth in the car. Shown below the Picture. The Hengst filter is only 271g vs 460g. the main difference for those Charcoal filter, is the amout of charcoal used in the filter. The more charcoal the better absorb ability. The plasitc bits also has weight, so I need to do further investigate, ie filter destructive testing to find out the fiter media weight.

The reason I want to change is the car has been sit too long, I would like to make sure the air quality is in top conditions, for Mrs and Kids.

I will try get those parts post to a certificated Lab which could do some testing and buy some more filter parts to check and compare.. If you guys are interested. ie,layers of filter,filter materials,weight of each layer, and filtration efficiency etc. Mainlly using ISO11155-1.


BTW, the Odor remover is nice, Car smell nice and fresh.

Gazwould might be along soon . He will let you know what he thinks of 'aftermarket' filters of any sort. The MANN filter will be as close (or the same) as MB OEM I guess.
