Windscreen shortage and Transfer Box

I recently got hit by a large stone on a motorway and this chipped my Diesel S windscreen so decided to replace it at my OPC. To my amazment I am told the windscreens are in short supply and I still dont have one after many weeks. I have now been asked to photgraph my screen so that Porscche can decide whether I need one or not!! Presumably they are prioritising the allocation of the limited screens available. Not what I expect from Porsche. Have they grown too big too fast?

I also think my transfer box may be on the way out. Accelerating away from rest or on a tight lock I get a grabbing/jerking sensation. Doesnt happen all the time so frustrating intermitent fault. The car has only done 20k miles
 
Try Autoglass. Minevwas badly cracked on Sunday. Reported to Insurers Monday. Autoglass replacing on Friday with OEM part.
Regarding your comment about Porsche ( too big too fast) see my separate post regarding my Cayenne rear bumper.

Bob - transfer case (TC) issues are common, but happily it is highly unlikely that the transfer case itself needs to be replaced. Rather, the TC fluid likely needs to be changed (a straightforward job). The TC oil is billed by Porsche as 'lifetime' fluid (I think it is an item in the 150k mile service), but it is most definitely not the case. Telltale sign is dark/black fluid, coupled with a burnt smell. I am going to change mine with every other engine oil service (NB: I do low miles and change the oil every 8k miles max).

My 2010 CTT had its TC replaced under a workshop campaign around 4 years ago I think, but still the car developed intermittent lumpy acceleration issues under hard load at 50k (issue tends to arise on the higher torque cars like ours given the load on the TC, but can affect all models in principle I believe). Oil was replaced and sure enough it was black and smelt burnt. No issues the last 3k miles. Porsche default to costly replacement of the unit when all that is typically needed is the fluid change to keep the internal plates operating smoothly (unless TC is in a real state owing to prolonged hard driving and exposure to contaminated oil say).


 
My transfer box just replaced under warranty too. Same symptons as yours. 2016 KN s, with 19k miles. Engine out job.
