Hello everybody, recently has the engine of my Cayenne V6 ( Bj. 2004) sounds like a diesel. The sound is subjectively from the left side of engine ( in direction of travel). Coupled to the noise is uneven running in the state . The error occurred suddenly and without warning after I turned off the engine and about 2 minutes later started again. I have read the following Durametric 2015_03_14_12_55_03_Cayenne Logfile.pdferror codes: P0016 Position camshaft to the crankshaft Bank 1 - Upper limit value exceeded , test conditions are not- completed , fault is currently active and is not Causing a DTC light P0300 Misfire detection checksum error - Implausible signal , test conditions are not- completed , fault is currently active and is not Causing a DTC light P0305 Misfire detection cyl. 5 - Implausible signal , test conditions are not- completed , fault is currently active and is not Causing a DTC light P0303 Misfire detection cyl. 3 - Implausible signal , test conditions are not- completed , fault is currently active and is not Causing a DTC light P0304 Misfire detection cyl. 4 - Implausible signal , test conditions are not- completed , fault is currently active and is not Causing a DTC light The measurements show strong deviations between the actual and setpoint ignition (partly > 16 ° ) and on all cylinders misfiring. Only on cylinder 4 absolutely no misfire is detected ( feather edge . But does not the evaluation ? ). At a higher speed, the deviation is significantly lower , but as soon as I go by the gas engine almost dies off. The data I 've attached a table as pdf. The engine is 140 thousand kilometers. At 100 TKM the complete timing chain drive incl. Camshaft adjuster was renewed ( elongated chain). Since then, the engine ran flawlessly and without any disturbance. I have checked the throttle and the LMM expanded and completely cleaned. The timing chain tensioner I have also expanded and it appears OK ( Piston moves freely ). The oil is inside for 9 tkm , spark plugs for 40 thousand kilometers. A car mechanic told me in a rough diagnosis everything points to disguised timing out ( timing chain ). In this context : Can the intake manifold (sorry I just remembered no better word , meaning the part in which distributes the air and is passed to the motor ) Remove without expanding the engine(to remove the valve cover ) ? Seems rather hard installed ? Does anyone have an idea on what the error or the running behavior might even suggest ? Timing chain would of course be the meltdown ... motor out etc .... Would be glad if I could get some input. Thank you in advance in advance
Hi, Today I tackled my first DIY service on a 2006 c2. After the service the engine check light turned on, any help would be great!!! Here is exactly what I did: - I wanted to check the spark plugs so removed 2 coils and 2 sp, I put them back on as they were clean. I plugged the coils back on, screwed them back on. - changed oil and filter. - change air filter, cleaned the Maf carefully with Maf cleaner without touching any component - cleaned the inside of the throttle body as it was somewhat dirty. Dried it completely before putting it back on and changed the seal. Note that when I cleaned it I moved the internal part to clean thoroughly. - topped off coolant Thank you for your thoughts and tips!!!
New to Porsche and this website. Just bought a pre-owned 2002 911 C4S with only 21k miles. New RMS and IMS bearing. However, idle is rough. Is this normal?
