Hello together. As is well known, the climate boxes (cases) are blocked over all MEB series. If you have already taken a look into the shaft of the interior filter, you will find that there is room for another pre-filter. In ID.6 and ID.7 there are dust filters in front of the activated carbon filter. The pre-filter has the part number 1ED 819 653. The activated carbon filter is also slightly different and has the number 1ED 819 644 All the known to me Born, Buzz, Enyaq, ID3,4 and Q4 have the Number 1EA 819 669 The above-mentioned filters are not available at the usual parts dealers. Only from MEYLE there is a set. MEYLE 112 340 0000/PD So if you need improved filtration, you will find it now.
