What do you mean? Everything I have read in WIS or otherwise say to keep the Smartkey 5 feet away from the EIS when you do work like "this". Whenever I am working with the w203's electronics I don't even brig the keys into the shop (once the cars is situated) and I have never had a problem...Where did you read that the Smartkey is supposed to be in the EIS when working on the I.P.?

maverik259

IDK what you talking about considering i said "I installed with the key out of the ignition etc"...

BF_JC230

Sorry, I misread...thought you said it was in the ignition...

Odd that it is screwed up...Was screwed up...

maverik259

when i first bought the car i was getting over 30 on the highway...but since I've add the rims and 2 10" subs and 2 amps in the back which I'm hoping is what is draggin my mpg down...now I get about 28 at the best on the highway and usually 25-26 for my city driving...

97W202

maverik259

97W202

maverik259

many factors affect the mileage - driving style (steady acceleration/jack rabbit), air pressure in the tires, air filter, spark plugs, electrical accessories, type of fuel used, etc.

On my '07 C280, I get 25 to 26 in city and around 29+ on highway with cruise - moderate driving style.
On my '04 C320, I get 23 to 24 in city and around 28+ on highway - moderate driving style.

how much should I expect to pay to have all my spark plugs replaced?

maverik259

nothing diy...it takes 15 minutes man...it'll cost you form the dealer like 200...i did it myself by simply going to auto parts store buying a spark plug socket, 6" extender, socket wrench and bought plugs off amazon...altogether cost me like $50

pcy

depending on the type of the engine (4 cylinders with 4 spark plugs, 6 cylinders with 6 plugs, 6 cylinders with 12 plugs) it can take about 1 to 2 hours max.

Independent mechanics charge about $60 to $80 per hour. So calculate...

Spark plug change is one of the easiest thing to do on our cars. You just need to be careful not to misthread or overtighten the spark plugs. Please search the forum, you will find several threads with pictures.

I am gonna look into that right now.
damn dude so many things I want to take care of before I continue modding.

I am @ 59 xxx miles.

Spark plugs
Transmission fluids
differential fluid
air filters
fuel filter (does anyone know when/why this should be changed? )

pcy

According to MB service manual, fuel filter should be changed every 60K miles.
So, at 59K miles, you are due for fuel filter change. Look on line, Bosch fuel filter on AutohausAZ dot com for around $35. It's not that difficult to change (remove 4 hose clamps, remove old filter, attach 4 hoses to the new filter, put 4 new hose clamps and tighten. That's it.

maverik259

ya i still need to change my fuel filter...im at 67k. I just have no where to do the work at the moment
