LOTS of SMOKE and hard warm starting

[MGaz]

My AEL is poorly

The warm starting problem has been like it for a while, well since i bought it. It would take ages to fire and chuck out a lot of white smoke while cranking the engine, and then it would clear as soon as it starts. But it would never do this when cold and it will start first time.

But now I have another problem, I don't know if they are related but recently Its been getting very black smokey under acceleration. slight acceleration results in a bit of black, but floor it and the car behind me will now 'literally' disappear. and its now kind of embarrassing.

No major loss of power but some times it feels like its lost some torque. (i could just be getting use to it tho)

There appears to be a lot of red rust caked on the walls of the water filler/expansion tank. tho this was there when i bought it.


Also recently, before the black smoke problem sometimes on a cold morning I would start the car and drive off and then hear a very loud high pitched whistle from under the engine bay at around 3000 rpm. I know the sound of a slipping belt, and its deffo not that. could it be the turbo? the noise goes away after about 20 seconds of driving.

The car has a chip, decat and iTG panel filter. other than that is totally standard.

Oh, and as far as i can tell there is NO oil in the water and no water in the oil. no sign of mayonnaise and i'm not loosing any oil or water either.

Sounds like your injection timing has moved due to belt wearing.
Or the temp sensor is talking rubbish.
Just changed mine my ael (just got same as you) as mine was not good cold starting even with timing bob on.

It's a DIESEL!!!






Ha ha Only joking fella hope you get it sorted.

temp sensor?.. I forgot to mention that the temperature gauge in the car has never worked either, except once on the way home one day I noticed it was working. Is the temperature gauge in the car attached to the same sensor that gives signal to the ECU etc ?

could this be causing a problem?

Also , where about's is the injection timing belt? Or do you mean the cam belt? Sorry, for my ignorance, Diesels are still alien territory to my petrol head.

Faily sure the gauge sender (the large one,bottom of water outlet on the head) only does the gauge, small white one on top talks to ecu.

The pump has a separate belt at the back of the engine. Timing does move as the belt stretches. You'll need vagcom to check and set it.
Take the engine cover off and all will be revealed!

HTH

cheers for the help thus far. I had the cover off a while ago just for curiosity's sake.. I'll take another look. I have noticed that some people's cars seem to have a cover for the rear belt/pulley's at the back of the engine, but mine is missing.

I have Vagcom, and the cable, but I don't have a laptop PC. If I borrow one from my mate, there's no risk involved for the computer is there? I'd hate to kill my mates alien ware, I couldn't afford to replace that as well lol

Just don't drop it!

Engine needs to be 80 degrees so go for a drive first.

Then its engine, measuring block 00, then switch to basic settings, engine will speed up then hit the TDI timing button, select AEL 1200 setting.
