Did you have to re learn the ecu for the new injectors? Mercedes says that we have to and if we do would it be okay to drive it to them if they aren’t learned into the system?
Would that be a fuel pressure problem I have an engine light on, and that’s what the computer said
Молодец не чего лишнего все по теме
Great Video and Very motivational.
My car was parked just because of this since last year ( i really loved this diesel)
After i watched your video i decided to fix everything and i did as i learned from you that take time and be patience with everything ordered all the parts and Tools needed or you recommended.
I just finished everything and i made sure everything is up to its standard as you explained.
Now car is not starting i try to start is couple of times to take the air out of fuel system.
Car doesn't start now , before it was running and battery is good as well.
Any recommendations??
What i look into next ?
Why all this complication instead of going on 606 6 in line an engine jewel. Easy to repair
Very well done mate and hello from Eastern Canada. One injector just started to leak on my 2008 Jeep Grand Cherokee WK. I hear a poofing noise and smell the gases inside the passenger area. I bought the 6-bolt and 6-seal kit from IDParts $24.95 US and the ceramic grease. I'm going to use one of the old bolts for the thread cleaning tool. They will all get replaced. The Rocal cutting compound is an excellent product we use it at my shop for thread cutting, a little bit goes a long way. A bit toxic so use with care. Thanks again.
What would cause a rattle on declaration?
My 2012 ML350 W166 got done at 87k and problem was already really bad, so 60k would be a good place to do the change of copper seals, which is what my mechanic also recommended.
