Sure? My mates runs a garage and used to be an mot tester, sure he said cant pass with any warning lights on. Of course I could be mistaken?

Then the 4cyl mercs remove the engine cover and it is like a sand castle but in coal you are lucky if you can see the injectors they are usually covered in diesel 'coal' hard solid baked diesel and carbon you have to chip away slowly coz of the wiring etc then the 6mm threads strip yes 6mm to hold an injector!! the last time just to change the injectors took me 1.5 days.( autodata gives 1.5 hrs) this picture is nothing compared to what the one I did, it was like this all along over all the injectors, and it burns just like coal .
Oh.
Mine is like that, I looked under the cover to test the glow plugs (leaving them be, having since learned they're only needed for emissions when cold).
I was worried that I may have an injector fault, when I saw the hard mess under the cover I thought it was melted plastic, but with no idea where from.
I promptly replaced the cover and decided all would have to be well, the idea of trying to extract anything intact from the mess looked unrealistic.

I don't follow that, what has a remap got to do with the above warning lamps ?

Thanks for clearing that up. When I was on the wagons you couldn't drive with any warning lights on in case vosa stopped you. Pain when truck and trailer won't communicate, didnt bother most but i paid for my own license.

The fault will be Injector washers blowing and damaging the connections to the heater plugs with the build up, It needs sorting and fast as it WILL only get WORSE, not a nice job, the way I did it was to have a vacuum cleaner constantly sucking in the opposite direction of the chipping action.
The wifes garage did one a few weeks back and burnt out the vacuum cleaner, it was on for so long !!

better image
This hard carbon finds its way in to the sump & blocks up the oil pick up pipe
First thing to suffer is the turbo
Replacing the turbo without cleaning the engine internals will be a very costly mistake
Lack of lubrication is the biggest cause of turbo failures

I'm not fussed about the glow plugs working, when I bought the car it was cold and had a duff battery and I was going to replace the plugs as the light was remaining on and I thought I needed them working, but I soon discovered that with a good battery the CDI doesn't need heat in the UK climate.
I was thinking I might have an injector fault as it was down on power and kept entering some kind of limp mode, but that was a vacuum type hose that had been pulled off, it now seems to be OK.

Agreed but Mainly on the likes of transit mondeos jags etc where the injector body / stem passes through the cam cover ie in the oil cavity, so that the coal is produced in there, and passes down with the draining oil into the sump, but with the mercs the injectors bodies are outside of the cam cover so just fills the void in the plastic engine cover still a mess though . The one I did the 'coal' was the EXACT shape of the underside of the plastic cover no injectors to be seen !!!

Same goes for the Volvo 5-cyl motor. I once spent a weekend getting two of them out for my son-in-law: ended up welding a 50mm square box frame that rested across the suspension towers and had a length of M12 studding threaded into the injector body to pull one of them out, bending the frame and an engine mounting in the process.
For the second one I used a 2T engine crane and a length of seatbelt webbing: when the injector popped out, the crane jib recoiled with that much force it put a dent in the middle of the bonnet.

Megane was the same, Stilo isn't much better (the battery tray is in the way of the nearside headlamp cover).

Coz you remap ecu to map out the EGR signal so that the ecu doesnt use that info basically, it is cheaper and it stops the EML coming on for anon flowing EGR.
that is different to remapping for power though if remapped for power they usually map out the egr anyway. BUT is usually more expensive coz you get more !

I have this job to do on my sprinter, but as its not actually leaking and forming coal, just has 3 bad glowplugs so its a cow to start in really cold weather, its been a round tuit for three years now, I just use the landrover when the weather is bad anyway, or if I have to have the van, crank it longer rather than risk having to remove the entire head to get the broken remains of glowplugs out in the mill :-)
Sometimes when you are working on a car you wonder if its deliberately designed to be awkward to work on, and the answer is frankly, yes, its intentional. I know that vauxhall made a huge payout to the guy on the line as part of their ideas scheme, where they give a percentage of the money saved to the employee concerned. His idea was to remove the drain plug from the diff on rwd vehicles, and when it came to needing to drain the oil, the mechanics had strip the axle, break the nose gasket, and take the axle off its spring hangers to get the oil out. They knew this, but it saved a quid or so per vehicle to manufacture not to need a boss tapping in the cover and pay a worker to screw a plug in, regardless if it resulted in the customer paying hours of labour to work round it.
After reading that about the body off on the new range rover in the press, I there and then decided that I would never ever be a customer of theirs ever again. All you can do is vote with consumer spending power and be as informed as you can be.

XC 70 4x4 exhaust manifold gasket you have to sit on the engine with your back to the w/screen and work backwards to get angle of your arms right and then allow your hands down to do the nuts and work by feel, because of the angle of the head, it's impossible to get from under as the exhaust gear box transfer box diff etc etc etc
I use stuff called, assemblee GOO green now, to help, it is like thick grease but not actual grease to 'glue' stuff to surfaces it saves having to hold one thing whilst fitting another

Just had a call about another merc ------dreading it.
I think merc should advertise the fact that they have a new side line
the heading could go a little like this.
MERCEDES not only build the fastest engines and F1 car------- we now have the technology to produce MAN MADE COAL with our diesel engines FOC to help save the world.

Try changing diesel injector on Crysler Voyager with vm diesel's, even the dealers used to have to smash top off the engine, to get the head off and fit a new head !! I did one for local injector specialist and broke the one injector body 3times welding various bolts to draw them out ended up welding 20mm cap head to the inj body and we made a 50 ton puller with a hollow pressram and that was touch and go. I recon the only reason they came out was we stretched them and made them thinner!!!

WTF!!!! Is that just old leak off diesel and leaky oil??

No it is injector blow-by and some fuel obviously, coming past the injector /head copper washers, because the bolt pictured is IMO, too small to hold the injector down properly and on some models they have ONE 6mm bolt to hold down TWO injectors so they start to 'chuff' but because of the engine cover they cannot be heard or seen, and the intense heat held in by the cover bakes it into coal.
In fact those pictures are not particularly bad, as said, the ones I have done, looked like another plastic cover the exact shape of the underside of the actual cover. as said like a sand castle.!!

Any decent remap wouldn't leave the EML on, if it did you would still have the same problem come the next mot

I just realised you misread the post, must try harder normski
EML wasn't mentioned
