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.

Burnt valve

ok I just love stuff like this,,,,this X5 with a N55 engine has been already at 3 different dealers for misfire on cylinder 1,,,,each dealer would replace ignition coils,,,spark plugs or fuel injector and they would ship the car saying it was fixed,,,,so my dealer gives me the car and tells me to find out what the problem is,,,,I knew 3 different set of spark plugs and ignition coils and injector did not fix the problem,,,,so I decided to check compression test,,,found 80lbs on cylinder 1,,,performed cylinder leakage test we had 80 percent leakage on cylinder 1,,,,I checked the intake no air leakage,,,checked the exhaust and found air coming out,,,ok now we know we have a problem internally with the engine,,,I installed a borescope to check out the valves but was unable to see anything,,,,so I had to remove the cylinder head and this is what I found,,,problem found,,,,happy customer

F10 IVM modification

Ok this is a picture of a IVM on a F10,,,,the IVM supplies power to the DME for the injectors and ignition coils,,,now by chance you might have short circuit one of the ignition coils or power to a injector the IVM might be your problem.will this is a little trick,,,you can cut the top off and you can see regular fuses inside,,,,just replace the blown fuse and you are ready to go again,,,instead of buying a whole new IVM.

X1 with B48 engine

Ok this was interesting,,,car came in 2018 X1 with a B48 engine,,,check engine light was on misfire cylinder 1,,,checked and swapped spark plugs and ignition coils,,,no luck,,,,swap out fuel injector still misfire,,,car wouldn’t misfire fire at idle only misfired while driving,,,performed compression test good,,,checked ohm checked harness from DME to injectors and ignition coils,,,,harness and signals were good,,,,what the hell is going on with this piece of shit,,,lol,,,,,everything checked out ok.Well the next step was to remove the valve cover maybe a problem with the camshaft,,,what I found was camshaft bearing cap bolt was broken,,,,could not find the other half of the bolt,,,,you can see what it should look like,,,,so at idle the camshaft was sitting ok but when you revel the engine the camshaft was probably walking and would cause a misfire,,,,BMW want us to replace all the camshaft bearing cap bolts and test drive and hopefully everything will be ok.

G05 X5 DSC unit

New X5 came in for a stupid software update,,,well after the software update the DSC unit crashed,,,tried to reset it a couple of times but it didn’t happen,,,one of the big problem is that the car was undriveable because the DSC locked all 4 wheels.So the fun thing now is that the DSC unit is part of the brake master cylinder,,,,not like before where the DSC was a separate unit,,,so now you get a new brake master cylinder with a DSC.
