GLK won't change gears on wheel paddles
This doesn't happen every time, but sometimes it won't reduce gear when step on gas and transmission doesn't respond to wheel paddles.
Don't know if it's related, but also DTC code P0299 (Underboost condition) lights up sometimes, and car seems to lose power.
Any ideas?
Thanks!!

Same Happening with me!
@Plutoe, so you're saying this isn't something "wrong/broken" with my GLK if I'm having the same problem (and I am) but rather an adjustment of some sort using the DAS?
1- What is happening then?
2- What sort of "adjustment" needs to be done? is it on the engine module or the transmission module?
3- What are the chances of this re-occurring and why does it happen in the first place?
My Car: 2013 GLK 250 Bluetec , 95K experiencing lack of kick down when cruising for a while on speeds higher then 100~120KM/H and suddenly trying to overtake a car, CEL comes on, car doesn't kick down, accelerates slowly.
After shutting off the car, car is back to normal acceleration kick down etc, until the same condition as above and same happens over again. CEL doesn't come off unless reset though!
The car at all states will rev above 2000RPM, so as far as I understand its not in "limp" mode, or is it?
Many thanks

I was just going to suggest looking at the lower right hose (looking toward the engine bay from the front) going to the intercooler. They seem to like splitting.
You can tape it up and run it until you get the new hose. Good job finding it and likely saving yourself quite a bit of coin.

My 2014 GLK250 is going in for it's second replacement in 7 years of the left hose. Same symptoms with the paddle shifters not working. Must really get a code reader. I've read on a different posting that the iCarSoft MB II is good for the GLK250? I suspect the first time I use it to chase a code I'll save the money in dealer labour.

That reader should be fine for clearing CELs and associated codes. I'm currently still using Lemur's BlueDriver and that works just fine too.
I would take a peek from underneath and see if there is anything around that hose that could poke/rub/touch it in any way. I must be one of the few to still be on the original hose at 122k miles and 6 years later...

And you scroll to the end of that thread (its last post), JUST BELOW THAT last post, you will see:
"Related Thread" ... and as you continue to scroll down, you are NOW in that other thread.
And if you tap Reply, you are accidentally now posting to the Related Thread.
Honestly, it's a 2-way street ... it's great for someone searching for info and can see common threads.
But, it's also a sometimes "not obvious" side effect of scrolling thru a thread and beyond it - you are now accidentally in another thread.
I know, I've done it before and you HAVE to be cognizant of which thread you're in.
And yes, THIS particular thread is a "Related Thread' to the one that is currently active "Glk not shifting to gear from time to time".
(sorry to go off-topic in this thread)
