New GLK350 owner question
My plan is to immediately do the oil/filter, air filter, and possibly plugs and coil packs.
How can I tell if the plugs are OEM or if they've been changed? As plugs are set for 60k B service, I'm assuming they are probably original.
Since I won't have access to records for the car, should I jump ahead and do the brake fluid and transmission fluid services or just wait until 60k?
Thanks in advance
More important would be to replace brake fluid, since the brakes controls the 4 matic -awd, and antilock , and stability system.
Replace transmission oil and filter, check differential oil condition . Do engine oil, replace coolant and maybe hoses and belts.
If it runs good the plugs are the last thing to worry about. The plugs are expensive and easily last 100,000 miles. Once you pull the plugs wires you also need plug boots . More expense. Do all the fluids and hoses belts first. My belt I replaced at 75000, it looked new. Fcp euro is where you will get the right parts delivered.
The mb interval is too long.
The brakes were overdue for a flush at maybe 40,000. I did mine at 40,000. And again at 70,000. It made a noticeable difference in braking power. Brake fluid absorbs water . The water and debris is what will ruin the Abs- 4matic - stability system . That is easy to do , it’s DIY with a helper.
coolant goes bad with age , it’s easy to flush out 50%.

Fuel pump seems like an overkill on 52k mile car.
I would add front and rear diffs fluids since you will be under there and they are easy to do. Front diff doesn't have fill plug and you can use the same attachment used to fill trans and pump in about 600ml (whatever amount comes out from factory) plus some to account for spillage.
You might want to check date cones on batteries.
Diff fluids are on the list.
One thing I find odd is that I'm unable to get the service history of the GLK. Even now, I can log onto lexus.com, set up an account in 2 seconds, add a Lexus VIN and boom....all services performed on that car are visible. I called my local MB dealer and was advised that they couldn't tell me the service history because I wasn't the registered owner. Is that true? I mean....this doesn't fall under HIPAA. Would be nice to know what recent scheduled service has been done.
My GLK hasn't seen dealer or a shop for past 10 years.
Dealers became so overpriced.
You better off pulling carfax you might be able to see maintenance there.

not online. I had to do that for my 22yr SLK at the local dealership. I guess they are not as up-to-date with technology as Lexus??? Don't know the reason but I was able to get whatever service records my local MB dealership had on my particular car. It was just a simple paper printout report (about 5 pages). The rest of the services were performed at independent shops (which I got from the history on CarFax report first). At this point, you'd probably be better off pulling CarFax first and then following "breadcrumbs"
... or just changing all the fluids and consumables yourself and giving yourself a piece of mind that it's done! Congrats on the ownership!

If by chance you hear any clunking when shifting or driving , from the drive train, do not wait to figure it out. I ruined my front u joint and drive shaft trying to get out of snow . If it had broken on the highway it could have destroyed the transfer case -Transmission and front differential. MB would want 10.000$ to fix. A guy posting here last year, had it happen , his 10,000.00 Glk, Mb wanted 10,000.00 to fix. The front drive shaft has no support of the drive shaft, incase it breaks ! An MB mistake. If it breaks it flys and flails until something stops it!
Agree with the above. Rather spend some time and money getting her up to a baseline, so I know what has been done and when....that's the plan.
I have used FCP Euro and they have been okay but don’t check parts against the VIN. MB Parts Source does.

I have to say that the ride between the factory 20 inch wheels vs these is unreal. Super comfortable now.
