Opinions needed. Jumping ship from a 2013 ML BT W166 to a 2018 GLE400 W166?




My 2013 ML350 BT is now sitting at 300 000km and is running very well except for a very minor oil leak from the oil cooler seals. It still has 2 years of warranty left or 40 000km from the AEM (Bluetec recall). I just spotted a 2018 GLE400 with 80k km and was debating between trading in my ML or just selling it and jump ship. The GLE is slightly more equipped than my ML (heated/cooled cupholders, 360 camera, etc.). What do you guys think?
A couple of questions:
- Will my set of winter tires on mags fit on the GLE? They're 19'' but I think the GLE comes with 20''. I'm pretty sure they fit on both models but maybe I'm wrong.
- I suppose the 3.0L TT gas engine is much more reliable than the OM642 right?
- I know my fuel mileage will take a hit, but will the difference be massive?. Diesel is about the same price as premium gas here in eastern Ontario.
- Any known problems with the 2018/2019 GLE400 model years?
- I do all of the maintenance myself (transmission oil every 100k km, axle fluids and transfer case fluid every 100k km, etc.). Is the GLE400 W166 easier to work on? I think the manual mentions 20k km OCI but I find that very long. Would 10k-15k be more appropriate? What about the spark plugs?
- Are the blind spot sensors located in the rear bumpers like the ML W166? On my ML they were problematic after a while from all the dirt/salt on the roads. I put dielectric grease on mine before every winter as a preventive maintenance... I plan on doing this on the GLE.
Any opinion/recommandations would be greatly appreciated. Thanks!

Spark plugs are a bear on M276 but doable. Other maintenance is typical MB nothing to be scared of.
ML and GLE are nearly 100% the same except trim/cosmetic items. And COMAND.




Oil filter is probably in stock at Autozone or similar. Maybe even engine air filter.
Send FCP Euro a customer service message to ask.












Just for fun, I checked spark plugs for a 2019 GLE400 and they sell them in a package of 8 even thought the suv has a 3.0 TT V6.

You will love the engine. Yes, way more reliable than the OM642 bluetec but, then again, what engine isn't. Maybe the 80's diesel Oldsmobile LF9 5.7L diesel is worse? I kid you OM642 lovers - all the tens and tens of you.

- the 3.0 T is a robust engine
- City wise you will almost have the same consumption. Diesel will shine in the highway.
- 2018/2019 almost perfect. Only 1 very minor recall in the vehicle.
- oil change do once a year or 10k which ever comes first. if you have done the fluids yourself in the bluetech then it would be easy for you for the 400.
- same location.
The diesel will run another 300k if you fix the leak. If the inside and outside condition of the vehicle is pristine there is no point of moving into the 400. You will miss the torque!!! if you want to upgrade the infotainment slap a 12.3 android screen on that and you will be in 2024 tech. Only thing will be missing is the 360 camera.

I love the OM642, but it's the whole SCR/Adblue system that scares me. After my AEM warranty is over, I'd hate to be slapped by a defective Adblue heater or other component. I guess there's always the option to delete everything. Other than the minor oil cooler seals leak, my OM642 runs great. It doesn't burn any oil and I never have to do any top offs between the 10k km OCI.
Regarding fuel economy, I mostly do countryside driving and some highway. Not a lot of city driving. I drive like 20 000km/25 000km per year so yes, I'll take a hit with fuel mileage. I think the GLE400 is rated at like 24 mpg highway while my ML350 BT is rated at 28 mpg highway. On paper it doesn't look that bad, but I'm pretty sure my ML gets better mileage than 28 mpg... I'll do some math later on tonight.








Just found this amazing item on AliExpress. Check it out!
C$242.38 40%OFF | Wireless CarPlay for Mercedes Benz ML GL W166 X166 2012-2015, with Android Auto Mirror Link AirPlay Car Play Functions

I was debating between going with a new android unit for a bigger screen but I finally went with the chip to retain the original look. My guess is that keeping everything as original as possible in the SUV would make it easier to sell or trade it in and get better value. That's my opinion of course and some might disagree.

I visited the 2018 GLE400 that I was interested in but I decided not to persue because it didn't come with the push start button option! I thought this was standard on the GLE... oh well. The Carfax report also said it was involved in a rear collision for 13k worth of damage... yeah no thanks.
As you can see, I'm quite picky so I'll take my time and shop around. I'd like one fully equipped with the climate control seats, heated/cooled cup holders and my gf wants one with massage seats...
I'm still on the fence about airmatic vs steel springs... My ML has the steel springs and I really enjoy the ride. My worry is that buying a used GLE400 with 80 000km+ (60k miles+), the airmatic suspension will be near the end of their life and will cost a lot to replace. I can do the work myself and save on labor, but the parts are still quite expensive.Quick question. Are the stock headlights HID Xenon or LED? Hopefully, they're not halogen... I'm asking because my ML has the lighting option with the Bi-Xenon HID headlights and I absolutely love them. Was there such an option for the GLE?

. Imagine a rear bumper with all the sensors involved in the collision, just in parts w/o painting and nothing deformed and you are 50% in that budget.

The only issue repaired under warranty was a switch control in the column which control lane keeping etc. it was malfunctioning and would cause the lane keeping assist etc to malfunction. The invoice showed the part cost as 750C$ lol.
My GLE has airmatic, amg package exterior/interior with night package, aluminum running board (they look good but useless), driver assistance package, advanced light package, heated seats, heated steering etc - it is fully loaded.
I have owned a Lexus RX350 bought it new and drove it for 5 years. After 5 years it never felt the same. In contrast the GLE is a class on its own when it comes to the drivability - the geometry on the handling is outstanding. It has crosswind technology- at high speed the car lowers itself dynamically. The interior fit and finish is impeccable. The advanced light package with its ability to change angle in order to light up the curve is nothing short of brilliant piece of engineering work.
Good Luck in your venture.

1 - reduce oil change interval to @5K Miles. For the tranny, shorten it as well to your liking. Just do not extend services as long as MB says (if you are out of warranty they will not come a fix it for you)
2 - increase oil weight to 5W40, and if weather permits even 10W40 (not during Ontario winter)
3 - oil solenoid pump modification. Discussed to death in the W212 AMG MB World forum
4 - Always warm the engine to normal temperature if you plan to step on it. Never floor it until it is hot.
5 - similarly, do not shut it off immediately after a hard/spirited run.
6 - if you tune it, be careful and do not overdo it
On general maintenance, @chassis has a compilation in his signature that applies to the W166 overall. Keep in mind the "V6 TT engine" was used on several platforms, so you can always check on other platforms' discussions.
