Hi help needed

[V6_SIG]

Hi don't know if I can post this here or not, I have a signum 3.0 v6 Cdti on a 06 plate done 147k, previous owner removed dpf, and had straight threw exhaust put on it, he also blanked egr off and unplugged it, but didn't have either deleted, I've put egr back to normal and only fault codes I get are to do with glow plug relay, but every time it's been driving for about 20 mins the engine runs a little bit ruff and I get blue smoke, if I turn it off and on again it is fine again. Has anyone come across this before? Any help is much appreciated thanks.

Welcome to the forum.

Sorry but this is the wrong place to post up a problem.

Do a bit of troubleshooting in the relevant sections, if you can find anything, them create a thread in the troubleshooting section.
