2015 GLK 250
New Member New 2015 GLK 250 Owner

Just wanted to introduce myself. Purchased a base 2015 GLK 250 for my wife this weekend (First MB, First Diesal). Just wanted to know if there are any quirks I should look out for.

Thanks

Not really a lot of issues have come up, we had the DEF error and 10 starts remaining but the dealer fixed that up the same day and nothing since. Enjoy your new ride we love ours....

There is a little bit of turbo lag which is worst in the summer with the AC on.

You will love the torque.

You go longer between fill ups.

You will rarely smell something like rubber burning when you shut it down during a regeneration cycle. Don't worry about it.

More short trips means more regen cycles.

Drive it and enjoy it.

We also just bought a 2015 BlueTec and I was wondering about the Regen cycles. We also have a 2008 Ford F250 6.4 diesel and the DPF regen cycles are a pain in the rear. I added a Scan Gauge II so we could monitor the regen status, EGT (exhaust gas temp) and DFT (DPF temp). We take the time to ensure we don't interrupt the REGEN cycle and don't shut down when EGT's are above 450 deg. During REGEN the EGT can reach 800 deg F and the DPF has gone to 1300 deg F.

What sort of indication will I get when the GLK goes into REGEN? The dealer / salesman didn't seem to know much about diesels. The Germans and Mercedes have been successfully making great diesel engines for decades, so I am less concerned about the MB, but I thought I should ask.

By the way, the 39 mpg we saw with the GLK on our highway trip this weekend was refreshing compared with the 19 mpg we struggle to see with the F250 during highway drives.

Thanks,
OJ

Or move to Oregon, or New Jersey. Sorry for the snarky remark. Our 2014 GLK Bluetec is averaging 30+ MPG since new. Our last trip taken a few days ago had the dashboard readout showing 39+ MPG on roads with 55 MPH speed limits, with stoplights, curves, etc.

I have never been able to tell when my 2014 GLK250 has been in regen mode. I had a 2008 Chevy 2500 that I could tell when it was in regen when coming to a stop.

The only thing I ever get from the GLK is an occasional bleach smell when I pull into the garage and get out of the car.

Congradulations and a hearty welcome ! Yes and no !

The diesel "quirk/s" is/are to understand how the 2.1 L twin turbo DIESEL parameters and the now 7 speed A/T converts to the real world driving as opposed say to gassers in general or the GLK 350 (like model ) in particular. Once you know and understand it, you can then apply it to your driving style and environments. So for example, even with 325,000 miles+ in diesel cars, I still RTFM and took time to see both the similarities AND differences. So for example, in one 100 mile leg, that I do a lot, I was able to post almost 50 mpg. This was @ altitude (7,300 ft to ZERO ft)

I would also RTF manual. (yes the manual/S are easily over 500+ pages) Some to many of the items are intuitive. However in the worst cases, what you really do not know or understand or just plain assume might give you grief.

All the best !
