Anyone have a CEL on their CDI yet? I did with substantial power loss, took it to the delaer today for check up.
Here is an updated pic with Brabus lowering prings and Brabus 19in wheels.

I believe some 05 CDIs have issues with misinstallation of intercooler clamp. That can cause check engine light and lead to power loss. The local dealer can reinstall the clamp correctly and will fix the problem. Nice pics though..

 

Viesel,

Did you ever get that small fuel restrictor in the fuel tank filler opening problem resolved?

 

No, they avoid it everytime I ask them to do something about it. I was passing through Orlando last week and ran into a fueling station with only big nozzles. They also told me that was a law that the restrictor has to be there, but I went and looked at the VW diesels and they dont have them, their tanks can fit the largest of the largest nozzles.

 

My '99 E-300 TD will likewise accept any size nozzle.

We'll be over in Lost Wages on the 26th looking at and test driving the new CDIs, and will check out their stock and see if they have that same restrictor as yours has.

Have you looked at any others since you got yours?

All US spec 05 CDIs have small fuel filler neck. According to Mercedes, it's due to flow rate of the diesel from the truck pump, which it can cause diesel to foam. It is advised only to visit passenger type fuel station. Cheers~

 

Good info. Thanks. BTW, I have heard of the term venting with diesel mentioned in the same sentence. Anyone know what this means?

 

You'll see that term used time and time again over on thee VW website, Freds TDI.

In fact, some VW owners do what they call a "ventdectomy."
It's a relatively simple procedure that I performed on my Jetta wagon back in 2002 when that vehicle was new. This involves removing a simple vent valve that is a holdover from the gas powered vehicles. By doing this, one is able to get the tank completely filled in a relatively short time when compared to the 15 minute time that it takes me to squeeze the last three gallons into my W-210s tank. Don't know yet if there is this same problem with the newer W-211s, put I guess I'll find out as soon as I get mine! I appears that this will be worse than with the previous model.

By removing this valve in the VWs, it is possible for that the air space in the top area of the tank to be vented much faster, thus allowing the foam or bubbles to escape more quickly, freeing up space for liguid fuel, which allows for the tank to be completely filled. As you may know, diesel fuel doesn't expand like gasoline will with temperature changes, so that 'safety' air space isn't really necessary.

I wish there were a way to be able to more quickly fill my W-210.
That extra three plus gallons that I can pack into the tank if I'm willing to take that extra 10 to 15 minutes after the nozzle first shuts off can add around 100 extra miles before the next fill-up. Filling mine the last time, I took on 20.5 gallons, and the low fuel warning light had not yet come on. From the pictures that have been posted of the restrictor that MBZ is installing in the newer W-211 CDIs for the US market, it appears like it'll be even more difficult to quickly be able to get a really full tank. That progress I guess?

 

Viesel, what ended up being the cause of your CEL? Is the car once again healthy?

As of right now they still dont really have any idea what is wrong with the car. They said that they can read the fault codes but unsure what is causing them. They are communicating with the reps in Germany and have to get authorization from them before they can R/R parts. They told me that they are hoping to have it figured out by Wed. Wed will be a week for the car in the shop. I really miss it.
Talking about venting, Thats correct about removing the vent and letting the air excape to make room for more fuel. I have been venting (actually doing ventectomys) since the 80s on VW diesel. I have not found any vents on the new cdi, but that STUPID restrictor that is actually designed for the gassers I think. I will be doing a restrictorectomy soon.
I will keep everyone posted on what they found out with the CEL and power loss.

 

Bummer! Please do keep us informed!

-Karl

 

Got the CDI back from the shop today and they were unable to determine what the cause was with the turbo surge and power loss. They performed all kinds of test and found everything within normal operation. Car seems to be running fine when I drove it home today, so we'll see. At least the CEL is off.

 

Viesel,

Please let me know how you do that, as I'll follow suit. Can't stand the long time that it takes to get that last three gallons in my W-210, and from looking at your picture and the W-211 gassers, I don't see it being any different, and it may be worse.

Filled my '99 today, and I was in the station 20 minutes to get it completely filled.

I'm wondering if that entire piece can be removed, or perhaps ground away? How to keep the debris from falling down into the tank?

I wonder if removing that spring loaded flap would help?

 

Im not sure if the 99s have it but if so there will be a small rubber flapper valve just inside of the filler neck. To start off with you can use the end of the nozzle to pry open the flapper and hold it open to releave the air inside of the tank while filling. Fill with diesel while holding the flapper open will vent the tank quicker and allow room for a few extra gals of fuel. You can actually remove the entire thing and filling will be much faster at lease for the last few gallons. Im just not sure if the 99s even have it. If so give it a try. Let me know if the 99s it, Im curious....

 

There is no flapper or valve of any kind in the diesel W-210s. It just takes forever to get the last three gallons in because of the foam, and the poor design of the filler neck. The opening is large enough, but there is a piece of metal going accross, not as a restrictor, but sort of a "rest" or support for the nozzle. On the W-210s, the opening is large enough to accommodate the truck sized nozzles also. I don't think that is possible with yours, is it?

 

I have had the same problem of power loss with the engine not kicking above 2000 rpm. There have been two causes, resulting in ten days in the shop first time round and another week second time around. Engine Control Unit replaced first time - known fault. Then kickdown switch was sticking - felt like driving in 1st, second then fifth gear - no power. Fingers crossed it is now fixed...........

 

The power loss seems to be, I think, due to the turbo surging. I think what ever controls the vains (waste gate) on the turbo that controls the boost is causing the turbo to drop boost for a second or two and you can here the turbo whine up and down when it drops and regains boost. It will go back to the shop on Monday. I am not getting a check eng light this time though.
