Every time the temp drops to 10 or below, it will not run, starts and then stops running after 3-4 min.
Is anyone else having issues like this?

what year is your GL?

opent2009

The unit is a 2008

Whats in the fuel tank; D1 or D2?

Go to wal-mart, get a bottle of Power Service and put 8oz into the fuel tank.

I actually filled the tank and put 16 oz of that very additive in to the tank, In Iowa they don't make a #1 or #2 statement.

This very thing happened 4 times last winter. I believe that there is a defect in the fuel delivery system.

I have had some cold weather issues as well... when it gets below 10 degrees out,

The vehicle will be running down the road at regular operating temperature and it it will stumble almost as though the fuel shuts off momentarily and then comes back on. It has also caused the engine to stall, but when I pull over it starts right back up. The latest round of trouble was over the holidays up in the Colorado mountains. Each time it happens, the check engine light comes on for a day or two and then goes out. It does leave residual codes in the computer, but I think that the codes are a result of the issue not what is causing it.

This issue does not happen very often, and it does not consistently happen when it gets below 10. It is very intermittent and even when it does happen, it seems to go away after 10 minutes or so.

I think I have narrowed it down to a non-fuel issue as I was running properly cold weather treated fuel the last couple of times it has happened with the same stuff mentioned above using double the recommended mixture.

At this point I think it might be an electrical issue, such as perhaps one of the relays that controls the computer or the fuel injection starts acting up when it gets really cold.

The hard part is since I live in AZ, the only time I have been able to replicate it is when I occasionally visit colder areas of the country.

If your SUV is a 2008 it is still under warranty. Take it back to MB.

My 2006 E320 CDi sits outside overnight at minus 20 degrees Centigrade and starts first thing in the morning every day. No problem whatsoever. In Ontario the oil companies also blend their diesel fuels differently for the winter.

Do you have an OEM block heater? If you do use it and see if it makes a difference.

I thought Kleeman tuning boxes only takes the engine to 240 bhp. 270 bhp sounds very high.

Like the alloys.

After I posted my reply to you I spoke with my good friend who owns a 2007 GL diesel without urea injection. The truck has a similar problem (very sluggish acceleration) after sitting out the car out in winter even for an hour or so (this time of year in Toronto the temperature can be minus 20 degrees Centigrade or worse during the day). He took the truck back to the dealership and they told him it is a fault with the "fuel pressure sensor". Water was accumulating in this device and had partially frozen, leaving little fuel to get through the system, hence the very sluggish acceleration. This problem gets better with the engine warming up but very dangerous if you have to go on the highway ramp.

I wonder if there is a recall in the USA? MB tends not to recall before the USA as lawyers here cannot do lawsuits on consignment.

How can they recall owners buying low-quality fuel?

Pick a high-traffic fuel station so you don't get water.

harkgar

You may be right. I pump only the best (Gold Diesel or Super Diesel) at busy gas stations. In the winter I use the PS additive you suggested every few tanks of fuel and I try not to go below half tank in the winter.

If the problem is water how do you get rid of it? Is the water separater located at the "bottom" of the fuel filter canister? If so, can I drain the water without removing the fuel filter? I am talking about my 2006 straight six engine not my friend's V-6.

240D 3.0T

Use a different station.

Carl Lassiter

As always, how helpful. He's asking what to do if he already has water in there, you fool. Just you run off and create yet another username so you can talk to yourself, again.

Harkgar- Drain the water separator AND also change the fuel filter. You can do one without the other but there'd be little point unless saving $50 on a GL is the plan. Position obviously varies from maker to maker but take a look under your SUV and it should be easily apparent where it is.

If the water dilution is bad then drain the tank. Expensive but cheaper than the alternative.

240D 3.0T

As always, completely useless.

Incorrect. If you actually read it, you'll understand he's asking what to do IF it happens. I gave the best solution, don't buy fuel from a bad source in the first place!

Grow up child, go troll someplace where you can understand whats being discussed.

He was asking HOW to drain it.
There is no point in draining the thing if you're going to change it!

Carl Lassiter

Ha, you are the one constantly arguing with others and being suspended. And you call me a child

Bad fuel can be found at even the best stations. Hence saying "don't fuel there blah blah blah" was a waste of bandwidth.

If you knew how to read you'd see he asked "can I drain it without removing the filter?" To which I answered that would defeat the purpose- you can drain it without changing the filter you see, thought you knew. Your response on the other hand was totally unhelpful, as usual. Get a life and a proper job you sad little man or you'll get yourself banned again.

Have a good 'un

240D 3.0T

You consistently act like little BMW boy.

Then stop paying for it.

Clearly you don't.

I agree. Come back when you have finished your Vo-Tech classes.

harkgar

I am old enough to say stop fighting. I take no offence in what 240D 3.0T said but would agree that his comment had not been very helpful to me. We are diesel nuts exchanging views and in this case I was trying to do some professional shoplifting on 240D! If you had told me to me to go and get it done with a mechanic, 240 D, I would have done do so. This is no big deal.

We shall all remain friends.
