Diesel EGR cooler recall

Here I have the EGR cooler removed for replacement for the EGR cooler recall,,,what happens is that we inspect the inside of the cooler with a borescope and if we see the cooling fin melted or clogged then we perform the recall,,,the recall includes new EGR cooler and new intake manifold.Here the new intake manifold you can noticed the 2 chamber intake rail system,,,the secondary intake flap opens for more power Here you can see the intake side of the cylinder head.Here the throttle body you can see all the black oily soot from the diesel inside the throttle housing. the whole job isn’t to bad,,,the intake manifold just slides out and so does the EGR cooler,,,,the whole job takes about 4hr.

    How was the carbon build up within the intake tract? My M57 (335d) was notorious for it.

    Merry Christmas btw!

    Got a question for you, I have a 2013 328i xDrive with the N20 engine. I posted about a week ago about my drivetrain Malfunction and as I suspected it was either the Vanos bolts units internal at the timing chain so that was c costly fix but I am good now. I have a minor issue with the Front Electronics Module. If I access it with either BimmerCode or Carly I get a FEM Coding error and says it needs to be loaded from a backup well this car has never been coded before so any ideas? From what I am reading I need a new FEM or have this one repaired if I want to acted this part of the coding. The car runs great and there are not codes when I check the car for it is not a functional issue just an access issue but I assume trouble is headed my way. Thanks

    diff engine—speaking of build up– my ’16 f30 4cycl turbo at 18k (prev own drove 3k in 2 years) should i inject some cleaner in the TBody to clean intake valve or wait it out. OR is that a no no to try cleaning that way..
    thanks for what you do.

    sorry its a gas 4 cycl gas trubo, so re; intake valve cleanup.. does hard driving help clean up or prevent intake valve build up on gas engines,,, or do i wait for walnut blasting


    • We haven’t had any problems on the 4 cylinder gas engine with carbon build up on intake valves,,,there should be no need to perform walnut blasting,,,,it was only on the N54 and N55 6 cylinder that had problems.
