While we are on the subject of resetting things, is there a way to set the radio station call signs. e.g. some of my stations that are say 106.1 or 101.7 have their actual call sign as in MIX or WSFM etc. Is this a function that can be down with the car system or does the station have to broadcast that information?(as my local dealer told me).

Mercedes GLK 220CDI (Diesel)
Sorry guys, I just joined and I'm picking up an old thread. I have a GLK 220 CDI (Diesel) and until now, I've given it in for its annual service. No complaint regarding the quality of the work (and indeed, there are some product updates that have been made while the car was in the shop). However, going forward, when the product line matures, I don't really want to spend close to $1,000 for basically an oil and filter change plus a few bits and pieces. I've done all my maintenance work on every car and bike I had over the last 40 years and I see no reason to stop. My only problem: is there any way for the DIY owner to re-set the Assyst on these later-model Mercs, or does it take some special software?
Thanks!
Thanks!

Glyn, you are great!
I did what you said. At first, it didn't work, because I guess I didn't sequence the thing properly. Basically, I tried again with your instructions under my eyes, but it still didn't work. I got pissed off and forgot about the whole thing for a while. Then I tried again, and this time it worked perfectly. Which means that MB probably programmed the thing in such a way that fiddlers are not encouraged. If you get it right first time (as a pro), it works. If not, you need to seek pardon, go to confession, bow your head and come back in penance. But if you do it right first time, and quickly, it works! Glyn, you saved me a few expensive A and B Mercedes shop services, believe me!

just so everyone knows, the sequence is a little different for 2010+ model years. my 2008 worked fine in the first key click w the center display on mph in the background. accept call and then immediately ok and hold down it comes up. my 2011 and moms 2010 BOTH need to be in the trip screen in the background or it wont come up at all. took me a few minutes to figure this out a few weeks ago when i did my second oil change and i was at almost 10k miles. its weird how the model year changes what it wants in the background?

Great info here. Two dealers answered my question of just oil change not a full Service A for my 2011 C300 only 2500 miles. They will change oil only, but will not perform service reset. If we reset it, will it void the warranty? Dealer has no record of Service A or B if we keep doing it ourselves.
My C is my weekend car for now. I think $200 or so for Service A on 2500 miles is a waste.

its actually best to do ur first oil change at 2.5k-5k miles to get rid of the immediate wear particles a new engine creates. Then u can do whatever ur comfy with. I do mine 5k or so, i use mobil1 0-40 and its great oil, but stick ur fingers in 10k miles old oil and rub them. Check the new oil the same way, its cheap insurance for less than 100 bucks if your keeping the car. I do it just cause im rough on mine its a toy not a dailydriver

Actually I do not want to do anything now. However, it's my first MB and I am not sure if warranty will be voided if I skip some type of service. Therefore, I like to do minimum, the oil change only.
If I am sure warranty is good, then I just wait till it's about 10K miles. Any comments on the MB warranty? Dealer will probably not tell me the truth; they want to make $.
By the way, 2500 miles are 50% city drive not really a stop and go, 50% on highway.

Mercedes GLK 220CDI (Diesel)
Yes, Youtube is great, thanks for the info. I just went on the site and there are some nice tutorials about oil and fuel filter changes. I wish there was one about changing the engine air filter on a 2010 MB GLK Diesel! The question being: does one need to unplug the ECU wires (the ECU sits on top of the air box on this particular model) or is it possible just to pull out the air filter screws, lift the top of the filter with the ECU in place and slip in the new filter element? I'd much rather avoid unplugging any of the electronics, 'cause that's a potential source of problems if one of the wiring pins gets distorted.

Engine Air Filter
Glyn, to the rescue!
You are the one who seems to have best access to the internal docs of MB. Do you have something with respect to the Engine Air Filter on a GLK 220 Diesel?
And enjoy the Cape area, you lucky guy! I haven't been there in thirty years, but I still have fond recollections of the Stellenbosh wineries!

I have a 2009 350 cdi with 4 button steering wheel.
I was searching everywhere for the last 2 months, and all I could find was the 12 button resetting. THIS WORKED FIRST TIME.
thanks again for the heads up!
