Hi

 

Skoda & TDI newbie, suffering.  Had a dealer change EGR valve/cooler, (fortunately under warranty !) on my Oct II 1.6 TDI, since I've had wispy smoke when stopping (nothing drastic but its there) from under the bonnet.  There's a fumes smell from near the DPF towards the centre back of the engine bay.  

 

I managed to take this photo with a mirror on a stick and an iPhone showing recent soot build up on the bolt between the turbo and the DPF.

 

Questions :

1. Do I have an exhaust leak ?

2. Are parts in this area removed/replaced as part of an EGR replacement ?

or

3. Is this a separate and unrelated problem ? if so what ?

 

Here's hoping someone can help me !

That looks like the clamp for the dpf to turbo there is a metal gasket between the two that should be replaced! If it has been then maybe the clamp hasn't been tightened enough some times its that? Its a 5mm Allen key but most of the time can only be tightened from under neath? This has to be removed to gain access to the egr valve/cooler on these 1.6tdi's might be worth checking the clamp hope this helps

I have the same problem with my 1.6tdi.

how much did that cost?
