#753 of 886 Gasoline Smell in Passenger Compartment
Mar 08, 2008 (1:32 pm)
My 2002 230 K is having an unusual problem. In the morning, and especially when its cold, the passenger compartment receives gasoline fumes. My wife has taken this car to the Mercedes dealer where we bought it. They found nothing wrong with the fuel tank filter canister and they replaced the mass airflow sensor, which was not a cheap repair. We also changed where we purchase gas, thinking that maybe the quality of the fuel was an issue, but it isn't. We've apparently not found the cause and neither has our dealer's repair service, which has been very good over the years. Does anyone have any ideas or similar experience? Thanks in advance.

That is strange. How long has this been like this? One thing you could do is take out the back seat and look at the fuel pump housing. Its not hard to take out the back seat at all. It basically pops off. Just make sure everything is tight and looks normal.You will be able to really smell gas with the seat out if that is the issue. To see how to do this, search for "W203 removing back seat" in a search engine that rymes with foogle. The first hit will show you how to do it. (This board does not like for people to link to other sites) Hope this helps.

You can put up a link to another site for the purpose of providing helpful information. What you can't do is say something like "go to xyz.com for everything you need instead of here".
#756 of 886 More W203 oddities

Looks like I have the W203...but didn't feel brave enough to risk popping it off and have the wife yell at me
I did find something else quite odd in that it looks like my back seats won't properly flip down ... seems to have a new (third) plastic clip thing between the hinges under the knees that's in the wrong position or something. Have to wonder just what the shop did to the car the last time it was in (I had them searching for a possible loose ground on the radio antenna amplifier).

Thanks for your advice. By looking at other sites including the one you recommended, I was able to develop a list of possible culprits for the gas smell that included the fuel pump housing (turned out OK), a leaky fuel injector (Thankfully, not a problem. That is a very expensive repair), and bad fuel rail seals (Close, but not quite it). The problem turned out to be a worn out fuel pressure regulator that leaked fumes due to deterioration in the unit brought on by cold weather.
Apparently, this is a growing problem in W203 engines and older C-Class models (1997-01) according to the mechanic, so W203 and earlier C-Class owners, beware. Repair costs are reasonable for this problem on a W203--about $135. Parts costs for other MB engine types might be higher depending on engine type and age.
#758 of 886 cost of regular maintenance regime?
Mar 25, 2008 (1:36 pm)
I visited a dealer in Northeast US to look at an '05 CPO 240 4matic w/ 25K miles. Was surprised when service mgr outlined "normal maintenance items" -
oil service every 10k miles - cost $180 - $300
new brake rotors every 20 - 24K miles - cost $1050
new tires every 20 - 24K miles - cost $800
Is this normal?

Oil Service every 10k is right. Mine was free until 50,000 miles with my dealer. Just an oilchange at my dealer is 80 bucks.
New brake rotors every 24k is not right. I did 55k on my wifes 240 until I changed them. Dealer was charging about 800. I did it myself. took about 2 hours.
New tires every 20k??? No way. I have 55k on my original tires. New tires for this car are about 450-550. You dont have to buy them from a dealer. Go to a tire store. I going to buy some very soon. These still have an ok amount of tread left.

#761 of 886 Electric Front passanger seat stuck!
Mar 28, 2008 (8:14 am)
I have a 02 C230 which I just purchased. I released the front passenger seat and put the seatback forward to get ready for a rear passenger. The seat automatically moved forward, and when it did, the headrest(which was in the highest position) got wedged between the winsheild, and the top of the head liner in front of the visor. The seat controls on the passenger side are not working now, and I cannot figure out how to unwedge the seat. Can anyone tell me how to fix this issue?
#762 of 886 Mercedes C230 1997 oil change
Mar 31, 2008 (1:05 pm)
Reading old posts could to determinate that I can't change my MBC230's oil myself.
Looks like this car doen's have a crankcase cap to drain the oil, and I need a oil pump or vaccum to drain the oil out. It's that true? or someone knows if this engine has a crankcase cap and where is it located.
