i have just removed the egr cooler assembly from the van
i did download the erwin workshop instructions for this which made the job quite straight forward, the only thing i would say is the workshop guide misses out removal of the lower metal pipe bracket large torx bolt which sits at the top of the gearbox, freeing up the metal coolant pipe that runs underneath the egr cooler, which 1 of the 3 bolts sits behind
by the looks of the cooler is is very blocked with crap, i could scoop out carbon slug / deposits with a screw driver after removing the front long pipe!!

i do have a brand new cooler part - EGR Cooler Repair Set 04L198512
so i do not need to try to clean out the cooler which seems to be the most blocked part
by the look of the cooler, we can hope the restriction was causing the errors to pop up for the flow threw it
the thing i am worring about is the P046C00 EGR SENSOR A Circuit range / performance error, Would this type of blockage cause that fault or could there be a problem with the actual egr electric motor part of the egr that actuates the egr vale opening and closing???
in the workshop manual it says to replace when refitting
1) Renew nuts and studs
2) Renew exhaust gas recirculation pipes following removal
do we really need to renew the front / back exhaust gas recirculation pipes, mine look in good condition, it makes sense to do the studs and nuts, making the assembly alot easier, and i did snap off the end of one of the studs 5mm removal tip
does anyone no the part numbers for these items listed below
