50K service - Spark Plugs needs replacement?
Hello all,
I just took my 2013 GL550 in for 50k service and dealer called back suggesting Spark Plug replacement. I am a bit surprised as 50K miles seems too soon to replace spark plugs. This is my first MB, so just wanted to reach out to the community to see if this is accurate or am I being taken for a ride by the dealer.
If it is required, any price guidance will be great too. Dealer is quoting me $700 for replacing the spark plugs.
thank you in advance,
John

50k is right.
The price...I would be more comfortable at the 400-500 mark at the dealer.
That's what I spent 2 years ago

6 yrs or 60k miles is the recommended interval for changing the spark plugs on the gas GL's.

That being said....the engine in yours is no different than those in the 2015s.....
So you may be wondering what is behind Mercedes' earlier recommendation.....
Beats me too...

Thank you all for the response. I will check the service schedule (hind sight, I should have started there). I will push on dealer to see if this is really needed or they are just "recommending".

Mercedes dealers have such *****, $700 for a set of spark plugs, price it like it's brain surgery and the plugs are of solid unobtanium. Thank goodness the change interval is much, much, much, much longer on my gl350.

The cost of plugs are probably the least of your worries with a MB Bluetec diesel motor. That motor is a friggin oil sludge and soot clogging nightmare if you follow the mfr service recommendations and use the MB recommended oil.

my comment was not one of smug superiority, rather it was aimed at the dealers and not the gasoline engine itself.

For your information and that of others with Bluetec diesel motors, you should take the time to fully read this article. If you follow this mechanic's recommendations to the letter, you may be able to stem the damage that your motor is doing to itself without your knowledge. If you already have a high mileage Bluetec motor and have been following the MB recommended service schedule, you may be beyond the point of being able to save your motor for the long term.

It's a shame the bluetec engines are handicapped in the US when compared to the worldwide market.
They are known and praised for their longevity everywhere else.
Dave is right. And even if you do stick to manufacturer recommended service intervals it might be best to stick a bottle of liqui molly engine flush into the oil before you change it.
It does work.

My 2012 E350 Coupe spark plugs change was at 60,000 per maintenance guide (V6 engine) cost $750. We also own a 2016 GLC, thanks for alerting us. I have always thought that new cars don’t need spark plugs replacement till 100,000 miles. Obviously I was wrong.

The next time one of us gets a straight answer (from MB dealer) to 'recommended' vs 'required' will be the first time

In what way are they handicapped in the US and not elsewhere? ( I'm not in the US)

U can try to fix your old plugs. I can not give 100% guarantee that they will earn again, but thanks to this article selfgrowth.com/articles/how-to-fix-a-car-s-spark-plug I had a couple of weeks ago to resuscitate a couple of his. Perhaps it will work for you.

Well back to reality - with 50K miles on a 2013 GL - before checkin I would suggest you consider 2yrs/20K miles Mercedes prepaid Service for $1,255 - which covers ALL recommended items for 50/60 incl plug change... for dealer service that's the best deal... 3yrs/30K is $1,750

$700 is very high to just to replace the plugs and does not include anything else. My Indi charged me $600ish (I don't recall the exact amount but was under $700). This included the A3 service, plug change, cabin and engine filter change. I had asked him to change the plugs a little early from the scheduled 60k.

I started on my plugs today. Was able to finish the passenger bank in two hours. The last bolt closest to the passenger firewall is a *****. No combinations of wobble and socket will work so I had to go to Autozone and pick up a flexible extension which burned up time to do the driver side. Driver side will be a breeze with a lot more room.
The spark plug extension tool from Mercedes is worth the investment. I will be all in $160 for parts and tools with 3-4 hours of time.
