Looks like only Bank 2 affected.They won't dry easy and yes, you can do a bigger damage. Misfire can permanently damage your catalytic converters and O2 sensors.
There are many things could cause this, however I'd check the Crank Position Sensor - it's a common problem on these. When the car is running try to wiggle the cable and try to carefully tap on the sensor and see if the engine stops. I'd advise you to take your car to a specialist if you re not familiar with MB engine management and electronics.
Possible bad valves, or worn cylinder. Need to remove the cyl.head to do more checks, without this it's impossible to give a true and exact estimate.
I bet the car has low performance as well. The EGR port seems to be clogged, also there might be excessive carbon deposit build up in the intake manifold runners. The EGR system and intake manifold needs to be checked and cleaned throughly. The P0102 can be a bad MAF sensor - very common on VWs, but also could be because of the restricted manifold. If you lucky you might be able to find a mechanic or a machine shop nearby with an ultrasonic cleaner and they can clean the manifold, otherwise you might need to get a new one. Anyway, first step is the EGR system, second is the manifold, than recheck MAF for P0102.
from $ 30 to $ 3000. There are many things could cause misfire at an individual or multiple cylinders. Could be a simple as a spark plug, plug wires, injectors to a worn camshaft lobe or a bent connecting rod. An OBDII scanner won't diagnose your car, only gives a clue where to start. Better if you take your car to a shop and pay for a REAL diagnostic and they will tell you what will be the cost to repair it.
Differential Pressure Feedback Electronic Sensor circuit Upstream Hose. Check the EGR's DPFE, there are 2 hoses attached, they might be disconnected, broken or mismatched, If the hoses are good, replace the DPFE sensor.
It's on the plastic intake hose, between the throttle assembly and the air flow sensor. Volvo calls it a "flame trap" and it doesn't look like the common ball and spring loaded PCV valve. It has a bayonet lock, so after you remove the vent hose attached to the valve, you need to turn it a little and pull it out. Sometimes it stuck and you have to use some penetrating fluid and play with it. If there is a plastic screen inside, just remove and discard it, than reinstall the housing. There is an O-ring, make sure it stays on the housing. There is a TSB from Volvo not to use the screen. If you need further help, let me know.
It would be good to know what type of services have been performed previously, if you tow, drive off-road... The 60K is kind of a big service and it includes the spark plugs, so I'd recommend to catch up with that beside the 75K. Get all the fluids checked/replaced. Replace: -air filter and check/replace the secondary air filter also -pollen filter -spark plugs -oil and filter, reset reminder -PCV valve -all fluids, incl. coolant (original red Toyota), ATF , Transfer case, differentials, power steering USE ONLY OE OR APPROVED FLUIDS! and make sure your mechanic knows which is the right fluid. -serpentine belt, check hoses Check if the valves has any noise and adjust if necessary. This would add a big chunk of $$ to the labor and parts, but can't ignore it! Perform a general check (incl. brakes, suspension, safety features, lights, wipers, etc.. What is not in the regular maintenance, but I'd ask for it: Clean the Mass Air Flow Sensor with CRC MAF cleaner and reset ECM adaptations. It will help to maintain good gas mileage and performance. Also get the service recorded in your maintenance book, or enter it here on the repairpal's maint. records, so in the future you will know what and when was done. Enjoy your car and drive safely, Zee
Looks like one of the flap's regulator is bad. It isn't something simple to do, better to take it to a repair shop.
It might need new PCV valves. There are 2 of them on the top of the valve covers. The diaphragm could break and the oil will enter to the intake manifold. There is a TSB (SI B11 03 06) out from BMW for the PCV valve service. If the PCVs are fine, you might have an internal engine wear. I have seen this problem on many 4.4L (N62) engine. It's usually due to extended oil change interval (the 15K miles interval is way too long, even with the best oil) and/or incorrect oil.
