Check out post #12 of this thread. He seems to have fixed the problem. I would use that as reference when you take it to the dealer.

Im intrigueg by this yellow stuff you mentioned... It sure does not sound right and how could the mechanic or tech not know what it is?

Oh man, almost forgot all about this thread. Well as it turned out it wasn't the fuel pump relay like we had hoped. Date of this thread is May 2009. After replacing the fuel pump relay the first time the car died again in late July 2009. Again they replaced the fuel pump relay and it was good for a little bit. Then in March 2010 the car died again. This time it was the fuel pump itself. According to the dealership the bad pump kept blowing out the relay.
So the total bill for the new fuel pump:

$2,278.81

Thats total, parts/labor and tax.

So far not a single problem with anything. (knock on wood)

Only thing I've had done since March 2010 is oil changes.

To this day I still have no idea what that was!

After getting the error code for the cps
I changed the crankshaft position sensor
. So now when the car is on and parked for about 10 minutes it turnes of ! Then I Waite then trying to turn it on it cranks but nothing then it finally turns on . But then I get the same ****ing code again cps ? But I just replaced it ?
I have no ****ig ideah what's wrong with this car man. Some times it accelerates by its self

Let me guess. you did not buy the part from the dealer or get a Bosh replacement. If I am right your replacement is probably DOA.

zuzu_pali

yeah but its brand new 12 hours old? and it can still cause all these symtoms ? how about the car turning of by its self after sitting for 10 min?

zuzu_pali

what is the correct brand or part i have to replace it with ? its a 2004 clk 500 w209

zuzu_pali

im going to put a bosch tomorrow, i will let you know how it goes

insame1

There is a reason I assumed and I was correct. Don't cheap out on parts its not worth it.


I recently order this one.

When you have problems do some searching. this has been covered a million and one times.

zuzu_pali

yeah thats the one arriving today il let you know how it goes . but the weird thing is the first one i bought was way more money than the bosch. and i hope this fixes the problem of the car turning of after 10 min on park. do you know the reason for that?

insame1

There could be a number of reason. If you are still getting the CPS code then it is most likely the part heating up and not making the correct contact/readings. The most apparent sign of a CPS failing is the car stalling when it is warm.

Just because something cost more doesn't make it better. There is a tone of info on this site and Google is your best friend when it comes to car repair. Do some good searching and you will find answers to the most common problems and usually the suggestions on replacement parts.

Dollars to doughnuts the new CPS fixes the issue.

after replacing the crank shaft sensor . car was running fine . after a few i get these 2 error codes p0600 and p0120
but i replaced it with a genuine bosch and it was perfict for a few after replacing the crank shaft sensor . car was running fine . after a few i get these 2 error codes p0600 and p0120
but i replaced it with a genuine bosch and it was perfict for a few minutes but after i decide to turn it on i get 2 codes . wtf manwtf man

also the fan is spinning high

insame1

Have you had your battery tested? also these codes are not for the PCS but the TPS. The code P0600 was set when the ECM recognized a loss of communication and control over one or more of these modules for eight consecutive starts.

Like I said above do some searching. You also might want to start posting in the correct forum so people with the same car as you can chime in .

zuzu_pali

my battery is brand new, battery,alternator , sparkplugs, sparkplug wires, mas is new ,cps is new .

so what should i check? because when i start my car fan turns on loud *** well, im going to go see if it does that now still. but with those codes what should i be checking for

Do yourself a favor and go get it scanned with Star. The money you spend will be worth it.
