The other day. The wife parked the car at work.

She said it did not want to start. I checked it out and brought my OBD reader. It threw out some codes of concern initially for the CAMSHAFT Sensors.

I had it towed to a nearby shop and they said the CAMSHAFT POSITION SENSORS had some oil on them and to have them replaced.

I towed the vehicle home because I did not want to pay the crazy labor to have sensors replaced.

I went ahead and replaced the CAM sensors, and nothing!!!

Still back to square one.

I also had my neighbor come by for a second opinion. First thing he checked was the Fuel pump. Also nothing. No humming or noise showing indications that fuel is being distributed.

That is the last time we troubleshoot'D the car. I am stuck and don't know where else to check.

I did a lot of reading and checked the MB Forums. It seems that a lot of issues with this car is pointing towards the CPS.

Please help!

Where is the fuel pump located and how to remove it?

alternater is fine . afer it sit's awhile after driven some noise comes from the passengerside and we disconnect the battery so it won't drain it

In night sometime normal in afternoon to totre failed

And also when installing them how do I repair the interior?

I had my first accident yesterday, I hit to curbs and ended up in a front lawn, the rubbed part of my tire came completely off when it was getting put on a flat bed, my bumper came off and it looks like both my tires are uneven.

I have an error code P0172 on a Mercedes C230 2005,
When the engine is hot and the car is restarted sputtering happens in the engine and rough idle for about 30 sec to 1 min then the engine runs OK,
The problem is only when HOT.
A new Fuel filter + the vacuum hoses (2 hoses) + new thermostat was installed.

The car on the highway when trying to accelerate seems not to accelerate. I put my feet down and the car speed doesn't increase much till you give it kick down, other then that the car runs well no shaking, stable rpm, stable temperature, only transmission jerks when shifting gear 1, the rest are smooth and ok.

Please can you give me your assessment because I have been getting different opinions and becoming desperate about the issue.

don't have key to door locks.

it started when battery&alternator light came on.bought new battery wasn't that.bought new alternator and car worked for three weeks then battery$alternator light came on again. had diagnosed and came up alternator was not working.alternator was under warranty got new one.had a mechanic put new alternator on and he didn't put timing belt on correctly.he tried to start it and it tried to turnover then it shut off and i saw a little smoke come from under hood.i smelled a burnt smell and car would turnover at all.checked all fuses and replaced starer relay.still nothing.mechanic stated that nothing that he did caused this but that maybe the starter burned out.bought new starter and got new mechanic.put new starter on and still no engine turnover.new mechanic stated that starter was not getting current.so he jumped car to bypass starter and engine turned over but shut right off.now what?

I just replaced my battery and now the car won't even come on. It has electronic key. I checked fuses, lights, doors, alarm works but horn is not. Please help.

A few weeks ago, my car started being jumpy and cutting off and now the sound of the engine is very different. It jerks ans misfires when i start it and it often misfires. My mechanic thinks it's a cam sensor problem but a few people have told me that the engine is busted.

I checked for leaks on the ground and there weren't any. The smell gets so intense that I have to turn my heat off completely and open car windows to rid the smell. Upon my visual inspection under the hood,I noted some liquid on what appears to be the exhaust intake? What could be the cause/part needing replacement and costs associated with this repair? Please advise and thank you in advance.

Does my car have an egr?

Some idiot has broken the knobs off the old unit so badly that new knobs will not repair the problem.
I have purchased a replacement module (used).
I need R&R instructions. This is a coupe.
Also have a Driver power door lock problem. Knob rattles and spins when pressing remote lock, but will not lock.
