Info on GL Bluetec
what is the difference between the 164 and 166? Is it just the year or model difference? What years should I avoid? I live on a farm and have a dirt road to get to my house. Is the sport package something I should look at? When did they stop putting the diesels in the GLs? Thanks for your time.




The OM642 engine was in production for over 20 years, having more than dozen different tunes and proved itself to be real workhorse.
Not the cheapest to maintain in MB diesel family as common oil cooler seals require about 20 hr to replace, but they keep on running.....
Newer will be better in any case as the motor got more power as the years went on.




Anyway, from what I check, in 2015 the Bluetec got new tune with few more ponies, what is not big deal, but worth to consider.
New tune usually also come with better mpg.
Than check for AEM extended warranty. It applies till 2015 models.
Other than looks (to me anyway), X166 is better than X164 as follows:
- Power fold-n-tumble 2nd row seats for easier 3rd row entry/exit
- More MPG: 26 vs 23
- Easier to refill DEF: Behind fuel fill door vs under trunk floor
- More HP: 255 vs 201
- More LB-FT: 457 vs 400
- Marginally bigger overall
- Smoother ride & better handling
- Having a spare tire
- Easier (but more expensive) Front Air Strut Replacement
- No more Oil Cooler Leaks

As soon as my Volvo EX 90 EV arrives (1-2 months), it will be available for purchase (for hopefully a diesel loving individual)
The forum has always leaned toward negative experiences, hopefully a positive one will be refreshing.

Moving from GLE on steel suspension to Land Rover on air, there is pretty big difference in handling. LR is giving me the "boat feeling" so less precise control, while softer ride means better comfort.
I wonder if GL on air suspension is having the same difference?
