Hi,

I do not believe in your theory.

A type 3 only has 1 aneroid cell and I personally have not seen any of them with a crack.

Type 3 androidcells is not dobble as on type2 androidcells? You have picture of a type 3 androidcells ?

Hi,

that is what you find in chapter 4. Type 3 has an aneroid and a differential pressure cell with ventilation.

I see now the picture of the type 3androidcells and I see this also have to chamber in the androidcells same as with type 2 androidcells, so it is posible to have hol in one of the chamber in the androidcell, than it will go too lean. You not understand that teori?

Hi,
some Opel guys had the problems the Type 3 MPS was clogged with oil and mud and did not function properly.

Some managed to bring it back to function without taking it apart by rinsing it several times using a fluid (maybe just fuel, maybe another kind of solvent).

Hi Norbert,

but that is a specialty of Opel MAP sensors, no matter whether type 2 or type 3. It happens as the oil moisture trap fails on that engine. Have never seen that on Mercedes-Benz cars. Cleaning and rinsing will by the way not work if you have a flutter valve inside.

No I do not understand your theory. If the single aneroid cell would leak, it would loose vacuum and thus expand on full-load - not letting mixture enrich there. In idle-run it should not matter much.
