Question Answered: My alarm goes off while I'm drive and when it's in park and turned off
June 22, 2014, 06:52 PM
The most common issue for this is a faulty Siren, usually located behind one of the front fender liners. Most Mercedes Benz dealers stock this part because they frequently fail. However, without doing any diagnostics, this is just a guess.
Question Answered: P0332 DTC code (Knock Sensor 2 Circuit Low) MIL Off
June 22, 2014, 06:49 PM
Your vehicle has two knock sensors located under the intake. They check for detonation (spark knock) and adjust spark timing accordingly. MIL Off means that the fault has not failed enough times consecutively to turn the "Check Engine" light on. If you drive it long enough, the light will eventually come on.
Most times, these codes set because water collects under the intake manifold and floods the sensor. When I used to see these codes, I would replace both the sensors. The intake manifold has to be removed to gain access to them.
Question Answered: My '99 SC1 starts right up at times but mostly has to crank for several seconds
June 22, 2014, 06:41 PM
Check valve is located in the fuel pump. If you are loosing fuel pressure when the car is off, its usually either the fuel injectors leaking, or the check valve in the pump is faulty. The best way to diagnose, is to install a fuel pressure gauge and an inline "shut off" valve between the pump and the pressure gauge. This will allow you to stop return flow when the pump shuts off. If it holds pressure with the valve "off", the pump is faulty. If it continues to drop, you probably have a leaking injector. Fuel test kits that include the needed gauge and shut off adapter are usually expensive, so it may be best to take it to a shop.
Question Answered: Common reasons why a 2002 Jaguar S Type 3.0 fails passing a smog test?
June 22, 2014, 06:24 PM
There are many things that can cause an emissions failure, it is important to know what readings were out of spec when it failed.
High CO can be caused by faulty MAF sensor, leaking injectors, faulty pressure regulator or bad converter.
High HC can be caused by dirty injectors, faulty ignition coils, faulty spark plugs, faulty cam timing solenoids/actuators or bad converter.
High NOx can be caused by faulty EGR system (if equipped), engine overheating (or running hotter than normal), faulty cam timing solenoids/actuators or bad converter.
Question Answered: Hearing sound inside my engine around the timing chain , I scanned shows p1519
June 22, 2014, 06:18 PM
P1519 has to do with the camshaft timing. This fault code coupled with the noise from under the valve cover, I suspect you have either a failed Variable Timing Actuator (VANOS) or a failed timing chain and/or timing chain guides. When chains/guides fail, most owners and shops opt to replace with used engine, because the front of the motor requires complete tear down (lots of labor) as well as all the parts needed to make the repair makes this a very expensive job. Special tools are also required.
Question Answered: What problem does DIC Message service 4 Wheel Drive mean?
June 22, 2014, 06:13 PM
There are many things that could cause that message. Its a generic message to indicate something in the 4WD system has malfunctioned. It could be the transfer case actuator and/or position sensor, it could be the front axle engagement actuator or even something as simple as the selector switch. In order to narrow down the possibilities, it will need to be hooked up to a diagnostic computer, so the fault codes can be retrieved from the Transfer Case Control Module (ATC).
Problem Reported: Power Window Regulators may Fail

<p>One or more of the <a id="ce_5600" class="ct_glossary tooltip" href="/door-window-regulator">power window regulators</a> (one in each door) may fail causing the window to fall into the door and not roll up.</p>
Problem Reported: Oil Leaks From Lower Engine Area
September 15, 2010, 10:07 PM
<p>The <a id="ce_8275" class="ct_info tooltip" href="/engine">engine</a> may develop oil leaks from the lower crankcase portion of the engine block. Our technicians tell us that the engine must be removed from the vehicle to properly repair this oil leak.</p>
Problem Reported: Fuel Level Sensor Failure
May 27, 2010, 11:08 AM
<p>The fuel level sensor in the fuel tank may fail causing erratic fuel gauge operation. Our technicians tell us that on high mileage vehicles you may wish to replace the complete <a id="ce_77" class="ct_glossary tooltip" href="/fuel-pump">fuel pump</a> module assembly if this condition occurs.</p>
<p>On certain 2005 - 2007 vehicles, General Motors has provided a special service policy covering the fuel level sensor, agreeing to pay 50% of the repair cost. This coverage extends for 10 years or 120,000 miles from the original "in service" date of the vehicle. Please contact your local GM dealer for more information.</p>
