I need a bit of help friends. :(

[nerooo_07]

Hi. Yesterday while I was taking care of the sunroof I was putting synthetic teflon grease TC2 on sunroof tracks for about 30 minutes. The radiator cooler doesn't start because there's an old problem. I was keeping on eye the water temperature on dashboard, was around 80 celsius, not more.
Suddenly I noticed there's a chuffing/ puffing noise. I thought so is gonna be the injector leaking. I open the hood, I took of the plastic cover, and it was wet the cover itself the side under. And there on the engine, I was putting my hand over the injector and I could feel the blow with air or diesel mixture, I don't what exactly is. But is blowing really bad. Is hard to understand which one from those 4 injector. Is in the middle.
My question is, can it turn in to a very bad damage? In to a fire or in to very loose injector?
Because I wish I could take it to the MB dealer, is 150 km away and here in northern Norway means almost 2 hours of driving. (
Please experienced people, this trip I want to be the last for the car with this leaking injector.

Not much help friend but that diesel/air is very dangerous in that the very high pressure diesel can enter the pores of your skin, do not put your hand over that area again with the engine running, people have been known to lose a finger.

 

[nerooo_07]

But my problem is if I can still drive another 150 km. Please

As this is just an injector problem, is there not a normal garage that could fix this, there is a lot of clever guys in Sweden, and the same must apply to Norway

 

[nerooo_07]

Thank you sir.
Here in north Norway where I live, there's a workshop with two polish guys, but I believe they can't have an Star system to program the injector if it comes replaced, even tools. They are a bit rough with the cars there. It's 20 km away, I've been there for a servo steering oil replacement, and they have empty the tank with one hose out, and they were steering entire left entire right with empty tank, and the servo was making very bad noise. I was reading somewhere is not allowed and can be dangerous for the servopump to flush it this way. Sorry for offtopic.
By the way, I wish I could drive it to dealer MB out 150 km.
I'm really panic when I start the engine an can hear the chuffing/blowin. I can even see the vapors with the hood open.
It can turn into serious damage?

 

[television]

I am not clued up enough on diesels to answer better, lets hope an indie comes on

 

[Xtractorfan]

These injectors can leak for ages and the car will still drive ok... You really do need someone who knows what they are doing to repair it properly,

 

[nerooo_07]

Yes sir, but if I open the bonnet the hood of the engine. I can see diesel fumes/vapors.
And the noise it comes from that injector leak it makes me panic, I've never been through something like this. It is a lot of hiss FFSS!! FFSS!! FFSS!! the same as this man here the noise, maybe a bit more.
Please little help. I hope nothing will happen if I'm gonna take this car for a long drive.

 

[Xtractorfan]

It really is a simple fix for any mechanic or diy'er, The biggest problem is removing the Injector clamp bolt and getting it to rethread easily back into its seating position.
I would agree that driving for 2 hours with an injector as bad as the one in the video will cause a few problems, and you may have to stop a few times...
I can only suggest you have a word with a few local mechanics and see if any are up to speed on the merc injectors.

 

[Irresistance]

I have had this problem on a W210. Five times. Only once did it give me a real problem because I had no money for a while and did not check the injectors and what I assume to be 3-4 months of leakage caused a decent hunk of black death around one injector necessitating its replacement (and massive cleanup)

With the other 4... not a problem. You notice the FSS FSS FSS as you call it, and you still have plenty of time to get to where you need to get.

When I bought the car, it had one leaking injector, and without me knowing it, I drove it 450KM back home. Only after another 200KM I got to the mechanic who told me about this injector problem, and he fixed it with simply washer replacement, no harm done.

My advise to you would be to go to your MB specialist, but try to drive gently. No fast acceleration, try not to go above, say, 2500RPM.

The other option, however, is a version of what happened to me with an injector in Spain/France, where it was leaking quite visibly, and considerably pressing down the accelerator would shut down the car (immediately!), show ESP visit workshop, and basically make it impossible to accelerate fast. Even then, I discovered the fault in Barcelona (first time it shut down) and drove until Avignon where I took it to an MB dealer. They did not speak a word of English, but that's another story

I hope where you live in Norway you do not have too many steep roads - as I said, I managed to drive across the Pyrenees with this fault, and only once did the car shut down during that time. But it requires a very gentle foot, no hard accelerating!

 

[Xtractorfan]

Exactly as Irresistance has said steep hilly roads will cause the car to smoke badly and even loss power.. but gentle driving will get you there...but it doesn't need to go to an MB dealer to get the injector problem sorted..

 

[Irresistance]

Well...in my case an MB dealer was unfortunately necessary... in the French case, they could not fit the injector back without it continuing to leak. Now hey, French mechanics and all - sure... but there was 4 guys trying to get it fixed to no avail. Finally, lucky me, they found a replacement injector somewhere in the warehouse and - charging only labour, I might add - placed that one instead. It is working to this day (This was summer of 2009) without a problem.

So - if your fault is as bad as mine... where you can see a "mist" of diesel/air mixture come out - this very well may mean that an MB specialist is needed.

In the other cases where you could hear the tss tss tss but NOT see a mist - indeed only a washer/seal replacement was enough, and this can be done by any normal skilled mechanic (provided the injector is not stuck solid).

Switch off and let the engine cool, then check all of the bolts/connections - you may be lucky and find one loose.

Interesting thread. How and why does this actually happen on diesels?

I've never had a diesel, the only issues I have had with injectors on a petrol is when I've nipped injector o-rings when replacing injectors and fuel lines before (popping them back on and squishing the o-ring by accident) and my god doesn't it pee out everywhere!

 

[Irresistance]

This happens because of the Common Rail Diesel Injection system. The fuel is pumped through that system at extremely high pressures, and so even the smallest leak can have very dire consequences. I have had the misfortune to gain quite a bit of experience with this on the W210... had all bar one injector leaking, one of which twice, and two replaced over the course of 100K miles.

And to top it all off, a while back my high pressure diesel pump also kicked the bucket, resulting in a most interesting fault (fuel leaking like a fountain, unable to drive, had to be towed...) - thankfully, I got a cheap second hand unit which was in perfect condition - a recon of these things even in Poland here costs 200 quid.

Generally, once the first injector "goes" (which in most cases means that the seals start leaking - not the injector itself) it is good practice to reseat/reseal all injectors. This is not a big job (about 20-30 mins per injector) and the parts cost a few quid a piece (washer, screw and a special triangular-shaped little "arm" that holds the injector in place) but of course I had to find out the hard way. This was especially interesting in Avignon with only French mechanics, no language to actually communicate, and 30 degrees while on holidays with the wife and kid.

 

[nerooo_07]

Dear peoples, I'm happy to see you reply the thread with past experience. Thank you a lot.

I have took a video this morning with my problem. The camera had the water proof housing on, so the noise is a bit reduced.

By the way this car has over 620 000 km, yes. : )

 

[Irresistance]

Yeah... that's unfortunately version 2 of the problem. You can try: Get in the car,take it out of the driveway, BE SOMEWHERE SAFE with no traffic, and floor it. You will get an ESP VISIT WORKSHOP warning on the dash and the car will stop. As in stop completely, the engine will be shut down ON THE SPOT and your car will appear dead. You will be able to restart.

I have had this fault, in fact, mind seemed a bit less bad, the cloud of vapor that yours makes is pretty huge. Mine was about half that size. But as I said, I could still drive with it, just slowly and gently.

 

[nerooo_07]

Hi peoples.

On Saturday I'm going to dealer with the car. I will put it on a trailer and tow it with a Transit tourneo.
I had a talk with them on the phone, and said it might be necessary to be changed two or even three injectors because of the one already leaking. What?
How much is gonna cost that? I can't afford it... sad.
Cheers peoples.

 

[Irresistance]

No that is not likely and be careful with this before they scam you out of thousands of Kronor The reality is that it is NOT the actual Injector that is often the problem, but the washers that seal it. The one that causes the puff of fuel mixture - yes, that one may need to be replaced, as mine did. But any other ones - no way. But resealing them - sure. This should cost about 15 quid in parts per injector MAX, and about 30 minute job (again, per injector)

Having said that, yes, it is advisable to reseal the other injectors. Mine kept needing this in quick succession, within about two years, about 15-20K kilometers apart.

But don't let them sell you a whole bunch of very expensive injectors, UNLESS STAR (the diagnostic software) will show that they are no longer within the norm. This is done with the engine running, reading live values as the injector is doing its work.

Hi people.

The intercooler two hoses are very wet where the o'rings come fitted.
Can you please have any idea what size is for replacement. I've tried to move the hose and seems very loose.
VIN in case needed = WDB2110061A520108
And if I am going to remove the hoses, I heard about a intercooler can be cleaned. How is that made?
Many thanks in advance.
