I think most of us know how much of a struggle it is to change the pollen filter on our R75 & MG ZT cars,so the last time I change mine I took a few photo's which I hope may help other members.
The diesel is a bit more of a struggle i think than the petrol engine cars, this is due to the size of the ECU (Engine Control Unit) & box it sits in below the front scuttle passenger N/S of the car looking from the front.
Make sure you have the right pollen filter for the job, OEM if you prefer them or a good quality aftermarket one fig 1
1
You will need to remove the outer grill scuttle panel fig2
2
You will first have to pull off the rubber weather strip fig 3
3
Now press the two tabs at the front edge of the outer scuttle panel fig 4
4
Lift off the outer panel and put it safe for later fig 5
5
Next step is to remove the plastic scrivet from the front of the scuttle panel fig 6/7
6
7
You next need to remove the first three clips at the rear of the scuttle panel fig 8/9/10
8
9
10
Lift up the front of the scuttle panel so you can remove the inner water shield panel fig 11/12/
11
12
Slide out the water shield carefully fig 13
13
With the water shield removed this will give you access to the ECM, if you look you will see a brown clip holding the wires, with along screw driver prise this open fig 14
14
Now the next step is you have to remove the ECM from it's bracket so you can feed it through the scuttle opening where the water shield was fig 15
15
Lift the ECM with it's box out and free from the bracket fig 16
16
On the back of the protective box you will see the two locating lugs which fit into the bracket in the plenum chamber, fig 17
17
Note the right lug is longer a straight this is to help guide the ECM back into the bracket later the left side should find it's own place as you lower it in place Fig 18
18
The bracket showing the side the ECM box should fit on when replacing fig 19
19
Now lets remove the wiring harness from the brown clip we undid earlier fig 20
20
you can pull the brown clip from it's bolt as it only pushes on fig 21
21
We are now ready to remove the dirty or damaged pollen filter, there are three fixing points at the top of the pollen filter box left fig 22
22
Right as here which need to be lifted up to release the pollen filter fig 23
Also the one in the middle top fig 24
24
Once the fixing points are lifted the pollen filter will pull forward, this pic shows further into the plenum chamber fig 25
25
With the top fixing point lifted you can now pull forward and lift out the pollen filter at an angle fig 26
26
Now the pollen filter as been remove you can inspect and clean the chamber by wiping out or hovering out any debris fig 27
27
Before you fit the clean new pollen filter note the tow slots cut out of the bottom of the pollen filter case fig 28/29
28
29
if you look on the new pollen filter there will be two fixing lugs which fit into the slots in the case when re-fitting the filter fig 30/31
30
31
You are now ready to fit the new filter again offer it to the chamber at an angle making sure the ECM is well out of the way and also the wiring loom is not in your way if so hold it back fig 32
32
Once you have it level you will be able to fit it into the case quite easy fig 33/34
33
34
You can push home the filter two ways bottom first reach in and make sure the lugs have located into the slots at the bottom fig 35
35
Or you can locate the top points then reach in and locate the lugs into the slots which ever you find easier for your self Fig 36
36
Next refit the brown clip you took of earlier this push back onto it's bolt fig 37/38
37
38
Lock in the wiring loom as before taking out the ECM fig 39
39
The last step is to lower the ECM in and onto the bracket remember keep it level and use the right long lug as the guide fig 40
40
You can now close up by refit the water shield and outer scuttle panel etc good luck enjoy the job, take your time and it should all go well for you cheers Arctic.
