Bought an Octavia VRS 2.0 Tdi from a private seller a few weeks ago. It needed some minor work doing it, clutch and flywheel replaced.

Recently I had used an engine carbon clean service as i noticed a very strong scented smoke coming out the exhaust so i thought i would give this a try. It worked well, but upon inspection from the guy who provided the service. He told me that it shouldnt be smoking the way it is and the smell was quite strong.

2 things he noticed and told me to check.

One - check if the car has a dpf in the first place, as he thinks the guy who had it before me, may have had it removed but may not have mapped it properly as the car is also showing an engine management light.

Two - from the turbo, when revving the engine, he noticed the turbo was releasing smoke and gas too, he suggested it might be that there is a dpf fitted but as it could be clogged up the smoke within the exhaust could be travelling back to the turbo and releasing from there.

If the dpf was removed and no remap done, how badly would this affect the car? I am looking for a place to get a proper dpf removal and map done in Birmingham, if anyone knows a reliable trustworthy place please recommend.

When the guy checked via the diagnostics machine, some sensors came up,mainly from the exhaust.

Some advice on the above from knowledgeable users would be appreciated. Is this a common issue, with a simple fix? Or will i be breaking the bank to repair this.

The car runs and drives fine with no issues. This is the only serious issue it has.

For the benefit of future searchers, I suggest you edit out DSG in the title. Sorry I can't help with the DPF issue.

Oops my bad, how to edit the original post? New to this site.
