Engine Problem - GL350 Bluetec
Hey everyone!
I have a 2010 GL350 and the coil looking symbol (Pre-Glow indicator lamp) in the instrument cluster is not going out; sometimes, it stays on for hours, sometimes it stays on for a few minutes after starting the engine. What's weird is that the engine doesn't even need to warm up; I live in sunny SoCal
Has this happened to anyone? Is this a sign that my Bluetec will have future engine problems? I got a CEL before service and also got the CEL today as well after the pre glow lamp stayed on... I just had the car serviced less than 3K miles ago...Then again, I doubt the dealership did the whole service considering they crashed my car into a pole and did body work on my car without my permission!
Thanks for the feedback

Could mean anything, you need to pull the engine codes. Considering that it sounds like your Dealer isn't the most ethical, I'm sure they forgot to tighten something up. Find a new dealer/mechanic.

Glo plug symbol that stays on usually means an engine electrical fault of some kind. If it flashes its serious, if it is on steady it's also serious but less so!

Thanks for the support you guys! The problem turned out to be a faulty ECU (at 53K miles?) and a couple of glow plugs (covered under extended warranty)

This happened to my ML350 BlueTech two weeks ago.

2010 ML350 BlueTech
"The Best or Nothing'?!
I'm beginning to think 'Nothing' is the better option...my MB is definitely NOT turing out to be 'The Best'! I just picked up my ML350 BlueTech (108K miles) from my local dealer this past Tuesday following a week's worth of repairs. In addition to the glow plug warning light requiring the control unit replaced (see earlier post) I finally had to get the increasingly worse oil leak repaired. My car required the oil cooler seal replaced, at a cost of over $2300! I contacted Mercedes Canada H/O and they agreed to cover parts and 25% of labour (11 hrs). In the end, the total cost of both repais was almost $2400!
This morning on the way to church (about a mile from my home) the engine died...I mean DEAD! Had to get towed to dealership, less than a week since I picked it up. Doing a little Google search, it appears that 'catastrophic engine failure' is not uncommon with this engine. I'll find out tomorrow when the dealership opens, but I hope this isn't the case.
9 montha ago, my transfer case failed, fortunately under extended warranty, or it would have cost approx. $8000 to repair. I'm beginning to think I've bought a 'Mercedes Certified' LEMON! I bought a MB diesel because I thought I would be getting exceptional engineering, quality and therefore longevity...my expectations so far have not been met.
