SOURCE: black smoke from exhaust

This is almost certainly a split hose - mine was the large hose coming out of the bottom of the EGR valve.

Speaking to a parts guy at my local Jaguar dealer, he said that the new part is uprated as Jaguar are aware that this is a problem.

The split allows more air in and results in the ECU changing the mixture and over fuelling - Black smoke is an indication of un-burnt Diesel. As well as the black smoke you may also notice a whistle/whine or sucking noise when you accelerate and a lack of power / lumpiness at around 2000rpm.

Hope that helps!

VW Caddy Mk2 1.9SDI, engine hunting with black smoke from exhaust.


Hi mate

I have 3 VWs and 2 Audis the VAGCOM but before you go out and spend a ton do the following

Change fuel filter
Get you a can of Seafoam

Since my tanks are only 14 gallons I used half of it every 6 months to keep injectors cleaned.

But because you have so much black smoke I will do the full can on a tank of fuel. Give it a drive it will smoke white a bit while it clears all the all junk. If that don't help that injected went to VW injector heaven.

Good luck

I have a 2005 vw caddy 2lt sdi it take ages to start and when driving black smoke comes out of the back under load. can you help?


Black smoke is fuel. Sounds like your choke is stuck on or if you have not changed your air filter in ages it could be real dirty so the fresh air won't get into your carb. I have seen filters so dirty the engine actually choked itself to *****. Is your check engine light on? You could have a bad fuel sensor or air flow sensor. That would do it as well. If you are driving with black smoke your gas mileage will be poor also.

Car quits when i slow down to come to a stop


Check for a vaccum leak. The easiest way to do this is by using a smoke machine. If you don't have one, you can buy a pack of cigs and blow alot of smoke into the intake boot where the air filter is until you see the smoke coming out of somewhere. If you've recently replaced anything, double check to make sure that you have all of the hoses and connectors in place, and all of the clamps tight.

Vw caddy sdi, when hot has a lumpy idle seems to shake the van, and leaves quite a bit of smoke,( blue tinted) at the traffic lights, doesnt seem to be using any oil over the last 600mile and seems to


The BST engine in your Caddy is prone to a couple of design flaws that can cause the trouble you are experiencing. Certainly, it could be an injector but could also be down to timing or the camshaft sensor. If you haven't had the timing belt changed, it may have stretched a tiny bit and that's enough to cause the problems you have with lumpy idle. Timing is adjusted on the camshaft pulley - but tiny adjustments can make a big difference. The EGR valves are also prone to sticking causing black smoke. Hope that helps a bit.

I've got a vw polo 1999 1.9 sdi. It has no power and it shudders when in low revs. Had a new diesel filter fitted today and it still has the same problem. It takes along time to get to 30mph. What is the...


The best solution I can give is that you take it to a VW mechanic. It sounds like the timing is off. Or the injecters are bad. But first respond back to me as to if it is smoking and what color it is. If the smoke is real black, its not getting enough air. Take out the air filter and rev it up and let me know if it is still black. If the smoke is gray or white, then the VW is not getting enough fuel. Get back to me and let me know either way. Thanks

I have a vw 2.0 sdi caddy 06 and have had the head gasket changed but now i have a lot of smoke when revving and very lumpy on idle. can anyone help me find the settings and sequence to set all my...


I suspect something is wrong with the head gasket proceedure. A head gasket failure is not the gasket itself, but something else is wrong, manifesting as a gasket. and yes, the gasket can be torn, but the gasket is a victim, not the cause. Usually there is head warpage but sometimes cracks. the lots of smoke sounds like coolant. Pressure test the cooling system...This is not likely an injector issue.

What hayens manual would i need for my vw caddy sdi year 2000. as i need to do the cam belt if you can help please let me no.


as the caddy van is based on the polo/seat saloon and has the same non turbo engine any one will do.
also the timing marks are on the top and bottom pulleys(you may need chalk to highlight them) PLEASE replace the tensioner at the same time as these go first.

I have a vw caddy tdi diesel van blowing smoke from exhaust what would make it do that.


a couple of things it could be , 1 it might be leaking valve guides+seals if they are leaking the oil drips on the pistons and when started it smokes for a while but eventually clears. 2 piston rings, if the bore is scored or you have a broken piston ring this will cause it to smoke, when engine gets to presure and the oil is thin due to being warn it can seep past either the broken ring or through the score on the bore, you can get it presure checked for that one to see if its 2. 3, being a diesel if the timing is slightly out this would cause smoke and it would be getting to much fuel in the pots to burn and you get a build up of fule that does not burn correctly, but you get other problems with that one, slow acceleration, jerkiness, that sort of thing....anyway hope that helps

Black smoke coming out of exhaust of a 05 VW Golf S SDi


Sounds like a bad MAP sensor. This will cause the same problems. Possibly an oxygen sensor not switching properly also.
