W208 How To's


My a/c seemed to blow too little, it was the cabin air filter.
I'd say if yu have 45,000 or so miles and about 4 years IT'S
a ABSOLUTELY DUE FOR A CHANGE, and it's likely not been done by anyone before as it is EASY TO OVERLOOK.
....Thanks guys!

My own experience: I have a 320.
I got the plastic trim out, the wood in my center console really needed some pulling on to get it to pop out but it did without breaking. I unscrewed the two screws for the ashtray. The ashtray did require allot of maneuvering to get out, but it will come out (it goes back in easier than it comes out). This is where things were a little different than explained in some other threads. I was expecting to find a black wire with a yellow stripe leading to the cigarette lighter but there was no black wire with a yellow stripe. There were two gray wires leading to the light for the ashtray, a brown wire leading to the lighter and two pink wires with green stripes that lead into one connection for the lighter. I suspected that the pink wires with the green stripe (could have been green with a pink stripe) were the 12V switched and that the brown was ground (a friend who has done stereos in German cars for sometime said that brown should always be the ground in a German car unless they went and changed the complete wiring system). I went and bought a voltmeter at Wally World and verified that it was correct. I used the t-connector and taped onto one of the pink/w green striped wires. I grounded it to one of the screws that requires an alan head to the left of the gear selector and everything worked great!!. I mounted the concealed display to my upper left on top of the driver air vent and it sits pretty well without any sticky tape. It is angled perfectly towards my eyes. Radar dectors are not illegal in NC and you will only see it if you are passing me. I was going to mount it in the instrument cluster but if the steering wheel is turned (I dirive on a twisty road quite a bit) it gets in the way of my line of sight. To get the concealed unit wire under the drivers leg compartment I used the air vent like the one on the passenger side and fed the wire up and around (behind the petals and over a few objects so that it will never hang down. I then just fished it up beside the dash like on the passenger side. Everything assembled easier than it came out and it looks great. I went on a road trip over the weekend and it kept me from getting a ticket where I think my old cheap unit would not have.
Ditto for me. I need to see where that damn crankshaft position sensor is. I think I need one. What are the symptoms of one of these sensors going bad? My mechanic is telling me it is. The car cuts off when 'warm'. It's happened at a trafffic light (twice) and after cutting it off to run into a store (twice). Come out of the store and the car won't start. The engine 'turns' but won't VAAROOOM! I can't be cuttin off in traffic so I'm taking it to the shop tomorrow. Thoughts? Comments?
-Remove engine cover
-Locate Torx screw/bolt holding CPS (See pic)
-Remove screw
-Remove sensor
-Install in opposite order
Is there a better, bigger picture of the CPS location?

Here’s what NOT to do: DO NOT try and remove the carpeting from around the back seats (the hole when seats are down). This carpeting goes under the rear tray and does not need to come apart. DO NOT force the deck up. It slides out easily if you get everything disconnected correctly
There is a little push clip in the center bottom of the first aid kit. Remove this. There’s another straight forward, just on the edge of the deck. Remove this also.
Remove the head rests. This will require a small screwdriver and a small head to see (if your back window’s too dark to see through. A good job for little brother to feel useful. There’s a little plastic piece that you simply depress next to the unit that holds the head rest in. Push it down and pull the chrome bars out. The plastic rings attached to the deck pop out very easily. Bad picture… Sorry – too close to focus.
Remove the side panels above the rear deck. They simply pop off and slide forward:
Pull the seatbelt all the way out and place the panels outside the car to give yourself more room.
Unplug the rear breaklight – kind of a pain in the *** if you’ve got fat fingers – again, little brother or girlfriend maybe can help. If you’re married – good luck – you know she won’t help.
Now, I’ve read that you should unbolt the rear sunscreen. I did, although I’m not quite sure I actually needed to. It seems as though it wasn’t connected to the rear deck – or, maybe it was and I just broke it?...
Next is to loosen the side panels (next to rear seats). You may remove them completely, but I knew that mine was a 2 day project and I didn’t want to remove them all the way yet. So, I just pulled the top rear enough to dislodge the deck.
Once you get the rear deck out – this is a really good chance to clean it.

All speakers have two wires: one with a strip (Negative) and one with no strip (Positive):
Basically all you have to do is:
1. Take off the 2 bolts that are at the rear of the diff. They are the ones that look like ??Bells??. All this is a rubber mount held in a steel housing.
2. Take off the 6 bolts off each left and right side of the diff that go to the wheels. They have that blue loc-tite on it so it will be tough to take off but put some elbow grease into it. It will be much easier if you leave the car in neutral and have the car on a lift so that the rear wheels turn freely.
3. Now take off the bolts that connect the diff to the axle (4 Big bolts I think). You will need a rachet and a closed wrench because you have to grab both sides.4. Now you are ready to take off the one center bolt still holding it up. The bolt is located on the middle of the housing and towards the passenger side. You cant miss it.
5. You will have to tug and pull to get this bad boy off cause after you have all the bolts off there is still a one inch rod that comes out of the diff and connects to the axle so you will need a friend to pull the axle towards the front of the car while you pull on the diff to get it out. Oh and this diff is about 80 lbs so it is VERY HEAVY so it would be wise to use a tranny lift or a lft of some type or you will get tired QUICK LOL.
6. Once you have it off take the bolts out from the diff plate and take the old fluid out and clean it well. Then make sure the old gasket is removed and then put the new sealant back on and put the cover back on. You will have to wait about an hour or so before you are able to put new fluid in but after the alloted time you can the take off the bolt on the side of the diff and fill it with fluid. Do not over-fill you will know its good when you can stick your finger in the hole and fell the diff fluid. The DIFF must be level when doing this.
Then just put it back on.
I will hopefully take some pics in one week so I hope this helps someone out for now.

I read the diy for the front bumper, but what do u do when you have a bumper with the headlight washers? how do you get that cap off, does it slide off?
