Help please:eek:
my Disco blows black smoke out the exhaust every time i change gear or tow a trailer! The motor had a Jermy Fern intercooler up grade before I bought it so i'm not sure if that is affecting it? The motor doesn't seem to be lacking in power, I've just checked under the bonnet to make sure all the pipe work between the EGR and the ECU are OK and I've found a pipe disconnected, it seems to reach the air filter so I will plug it back on, might that be the problem? Any ideas please:confused:
 
Sounds like they did all the upgrade tweaks but din't adjust the smoke screw setting in the injector pump. Google "tweaking your tdi injector pump" I'm sure you'll find what your looking for.

Oh and get rid of the EGR valve by blanking it off.
