Car lost power and started putting out black

Question edited for clarity and translated into written English.
Question moved from Ford to Jaguar category.

You should always take the upgrades. They are fixes to known issues.

All Diesel engines are slow to start as they need pressure and heat which happens after a few revolutions of the engine.

Rough Idle is normally because the Throttle Body and MAF need cleaning.

what you need is carb cleaner or throttle body cleaner then unbolt it from your engine, unplug everything hooked up.to it then place a shop towel over the opening left on your engine for nothing falls in then take your EGR valve and place it on newspapers, or towels and spray the heck out of it, let it sit after spraying it, and repeat after you got it cleaned up, let it air out for a bit, and bolt and hook it back up, this is just a temporary fix it sounds like you are running rich if you have a scan tool, check your fuel trims they just might be off a little bit, if it took.about 4 years to.start smoking again, but if you are going to be keeping it for some time, then I would check the fuel trims or have them checked.and fix, it.could be.something as easy as a vacuum leak

Diesel engine? Black smoke = your injection pump is broke

Did you have a question ?

Could be in the timing causing this...I would suggest taking it to the shop..Many things it could be....hope this help and if so please rate this post..

if there is also black smoke coming out the exhaust - and the problem is intermittent - then it's the EGR valve - it sticks open - will need replacing.... Happened to mine this morning and this is what the Jaguar Assistance guy said. Mine is a 2006 2 litre X-type.

Diesel engines always put out black smoke, so it is probably normal.

Just an idea but the Ford Mondeo ( european car ) from which I believe your engine
is taken has a habit of splitting a low pressure tube at the back
of the engine this is a relatively
cheap, easy fix. The other symptom this used to throw up was a
little more black smoke from the exhaust and a pacing/ surging from
the engine.

hi, you got a turbo problem, get it checked at the local shop, sorry cant help anymore
