X15 constant regeneration

Did you do a full EGR tune up? - https://rawze.com/forums/showthread.php?...7#pid73167

Have you done injector leak tests on it?. - https://rawze.com/forums/showthread.php?...3#pid75483

Do you have oil consumption more than 1 gallon every 4,000 miles or equivalent hrs?

Did you check the regen history? The InHg shouldn't be more then 3 consistently.

Did you take the down pipe off and snap test to check for large amount of smoke?

Have a friend with a 565 x15 that had similar symptom with daily regens that upon snap testing with the downpipe off literally smoke out the shop, luckily he was at a stealership that knows what to look for instead of blindly following a diag tree.
He got a full set of injectors under warranty luckily...
I personally had a injector not atomize properly (white smoke) that cracked manifolds and eventually the turbo itself until I caught it doing a snap test with the manifold off...
Also recently had an injector get stuck under full load, it didn't misfire either letting off, EGT would go the moon until i freed it up and ran good until being replaced..
You need to figure this out before you service the cans and not fire the parts cannon like the stealerships usually do!!
