These would do just fine. I have purchased a couple set of these wires from here for other MB's I have owned.

bheng

okay cool. i'll order this set.

do i need to get the 17m spark wire tool or will the universal one that they have suffice?

Mka77

I just used a 17mm wrench to pop the wires off. They can be a real pain in the a$$ to get off. wear gloves. Some really sharp edges in there.

bheng

yup gloves are a must. i cut my hand trying to feel out where the cps was. felt pretty dumb after i found it too

i bought the universal puller that they have. i went my dads friends auto place to use their tools when i had the cps problem. he was kind enough to let me use his tools. and i asked him how to to pull the wires out and he showed me how to do one of them and he had a similar tool to the one i ordered. lets home i can do it on my own now LOL

gonna def do my research via stff before i start replacing the wires. i know there are different lengths.

Mka77

How did this work out bheng? Get everything changed out?

bheng

lol i was just about to update this.

sadly but NO -_____________-

so i changed to the coil packs. took it for a test drive. drove fine for about three or four blocks. then i decided to turn around and head home, then a block away from home, clk took a dump and died. everytime i started it, it was would rough idle, shake and die. tried starting it a couple of times, waiting in between each start (car didnt get that far)

at one point, it wouldnt turn over, just crank.... so i just called my housemates, pushed the car home (1 block).

checked the voltage on the battery on the onboard computer. read 11.9. jumped the car got it to start. left it idling, and it still died at idle. i let it run to see if what could be the problem. i suspect the alternator. so after like letting it run on my driveway for 5 min, it would stall. finally on the third try...(guess third times a charm) it stalled but gave me a BAS-visit workshop message.

I dont think its the battery because i am able to crank it and have it turn over. whats left is the alt, right?

going to try to get my hands on a multimeter today to confirm

thanks for the check up tho! lol

EDIT: i apologize for the poor grammar and such. mind is kind of all over the place now.

Can't wait to see what the actual problem is

Glyn M Ruck

You checked that fuel pressure yet?

bheng

negative. thats on the to do list.

EDIT: another noob question... where is the shrader valve located? I did a search but I found a diagram of it but dont know where its located on the car...

Glyn M Ruck

On the front U shaped rail that provides fuel to all injectors.

update: to any of you following this thread or keeping up with my car, thanks i really appreciate it. good to know my fellow tribe members are still out on the lookout of my well being. lol

that being said i brought it to the dealer on friday. got a lovely c300 loaner for the time being. today got a call from the stealer. fuel pump went bad.

so im getting that installed at the dealer. the question was brought up whether i should replace the fuel filter? as well as the motor and tranny mounts?

what do you guys think? the fuel filter would be an extra 300 and the mounts would be around 1k in total....

should i pull the trigger on all the repairs or do the rest at an indy?

It's only money they say...

I would do the filter, but DYI or indy the mounts.

There is a tread around on mount R/R. I think Klinh was the author, no positive though. He may chime in.

Glyn M Ruck

Ah great! - So it was fuel pressure low. Please do a new filter. Mounts are condition dependent. Their replacement can make things feel like a new car if they have deteriorated.

W209 fuel filter
002-477-30-01 $62 US

Last time mine was changed was Jan-2010. I bought it at an US dealership.

bheng

So i have replaced my fuel pump. it was pumping 35 psi instead of the standard 55.

car feels great. i honestly couldnt tell the motor mount vibration at all... so i think i will hold off a bit. I think i will do the fuel filter at an indy or attempt the diy myself. it doesnt look too bad, just a messy job.

EDIT: so as of now, i have replaced, the cps, 12 sparks, 2 coil packs, fuel pump....and now im debating whether or not to change the wires. i currently possess the karlyn sti wires from autohausaz. i have not replaced them yet. debating if i should return the wires or just do the swap.

Mka77

Glad to hear you're back on the road. I'd just hang onto the wires and replace them whenever you feel like it.

Glyn M Ruck

Yep! you are getting into wire trouble mileage. Delighted she's fixed!

mis3

What is this wire trouble mileage?
I have higher mileage and I do not recall they replaced my wires. If the wires are bad, does it throw a code? Do these wires deteriorate over time?

Glyn M Ruck

Wires tend to play up at over 100K miles. They develop resistance. It's very dependent on underhood temperatures over time. You will get misfire codes P0300, 301, 302 etc.

I generally advise people to leave them until they start getting the odd misfire code because I've seen them go 200K in some conditions.

The only possible reason to change wires early is that bad wires and/or plugs can lead to premature coil pack failure as the coils have to work harder.

mis3

Thanks for the clarification.

Do these wires deteriorate over time? Do new wires improve the car in any way? Fuel consumption, performance?

Glyn M Ruck

Yes they deteriorate over time. With modern high energy ignition systems you won't see a performance drop or rise in consumption until you get misfires.

mis3

OK. I will wait then.

Too bad. I am looking for small items to improve my car.
Like after an oil change, the car feels better right away.
Same when I changed my ATF last month, and that's was a big difference.

bheng

I will hold onto the wires and change them in the summer time.

i had my tranny fluid changed at like 60k mi. i will probably do it once more around 110k

i will keep doing oil changes every 7,5kmi. and try to change out my fuel filter soon.

other than that, once again, i thank this forum for troubleshooting me through the worst of times with the car. I feel like i have a new car again and will last me another 100k with ease. granted, i am a bit worried with such mileage but i love my car and have done too much work on it to let it go so easily. haha.

thanks again tribe members

Not sure if you have mentioned the mileage of your car.

Mine just passed 150k miles and it is still going good, more so now that I did the transmission service. My car has been well-maintained since new and it's worth the effort.
