Help black smoke!

hi everyone i finerly got myself a cupra a week ago. but today it compleatly died on me. it was running and boosting fine in the morning but then on the way home it felt like it was in limp mod, but then lots of black smoke misfiring the lot....
only just made it back home currently when you start it up still black smoke and misfiring im new to cupra and im seriously worryed.

cars running 220hp full milktec. 007p, forge intercooler, stage 2 remap, think thats about it and a bypass.

It could be a number of things, but first thing to check would be Coilpacks...

 

[fourtwofive]

thanks mate hope your right about the coils.

 

[RichN]

Best bet would be to get a laptop with the free version of Vag-Com software and the cable off eBay and run diagnostics to see what faults have been logged.

Is the engine light on?

 

[fourtwofive]

ive already got vag com and cable tryed it doesent work with my laptop. no engine light on at all.

 

[tommy2008cupra]

check to see if coil pack has popped up a bit higher than others, or take them out and check connection underneath if it is black new coil pack mate

id say boost pipes come off

id say boost pipes come off

So would I. Almost certainly.

 

[tommy2008cupra]

if boost pipe was completely off car wouldnt run at all

It would. Just REALLY crap. He said he just made it home. It is really difficult to drive a car with a boost pipe off.

Sounds exactly like what the problem is. Black smoke is caused from having a boost pipe off.

 

[tommy2008cupra]

really cos when a pipe went on mine it wouldnt even idle it would just cut out, it wasnt goin anywhere, could be a large boost leak but tbh we could be here all day guessin unless we have a look at the car or vagcom it

Wouldn't idle no but it would be drivable to a certain extent. If you unplug the MAF you can run with a boost pipe off if things get desperate like it did with me when I had my spring clamps and nothing but my hands to get it back on... Jubilees in there now and a 7mm socket in the boot!

thanks for all your help guys just got home from work going to give it a good check over tonight. fingers crossed....

 

[daves ibiza]

could be coilpacks or injector plugs this happend on mine it caused engine to misfire make sure the clips are sercured on plugs

 

[fourtwofive]

hey guys took everyone advice on checking the coil packs. got all new coils in and new plugs. still has a misfire and slight black smoke i think it over fueling. checked all pipes. anymore advice?
the problem seemed to happen when i uses unleaded instead of unleaded v power. does this matter? cant get it vaged because the car wont drive.

 

[Ibiza125]

You sure you've checked all the pipes from underneath the car as well going to the intercooler?

 

[krisbutler02]

intercooler intact ?
split hoses?

using 95 ron wont do that i dont think

 

[fourtwofive]

just been under the car no hoses split nothing looks broke. i think its over fueling is that common? im a cupra newbe..

 

[fourtwofive]

cracked it got the software running on my laptop cleared all fault codes took it for a spin. came back one fault code lambda sensor. does that sound correct?

 

[jonnyblease]

could definitely be the lamba sensor
