Hi all. Need some advice which will either mean I keep or sell my car. 

I have a 2012

Spoiler

mk2

(I belive it is a mk2?) octavia vrs tdi cr. 

Started to notice smoke from the exhaust, not black. It is not noticeable all the time (no big clouds following me), Still there though. Does smell like it's burning oil though all the time, very acidic. 

Performance seems normal. 

Coolant seems fine. 

Oil seems fine. 

No leaks or loss of oil. 

Also noticing the smell in the cabin, mainly when stationary and the heater is on. 

No exhaust leaks that I can see anywhere. 

 

Car history:

 

Around 126k

Turbo replaced 1yr ago.

exhaust gas temp valve done 1yr ago. 

Cam belt and lambda sensor done 2 moths ago. 

Mot done Nov 21, no advisories. 

I use the car about 4 times a week and do atleast 80 miles per trip, varied styles of driving. 

No warnings on the dash. 

 

Important factor.:

I bought this car around 2 months ago, none of these issues were there then..........… thinking that there was underlying issues hence the sale? 

 

Either way i am still after advice about the above. 

 

Thoughts and ideas will be greatly appreciated! 

 

Many thanks 

 

David

Others will no doubt comment but I'd check the hose from the crankcase breather.  If it's split or off you'll get  crankcase fumes which smell pretty acrid.

Haven't noticed anything like that. Would that have any effect on the exhaust smoking?

SO what colour is it? The colour is potentially diagnostic.

I t looks grey/blue?

Quick update:

Used some hose repair tape on what I thought was a perfectly fine crankcase breather hose (to potentially get rid of the acrid smell while I find the smoking exhaust problem) .......... Ran it up to temp while looking /listening for faults.

Did some mixed driving styles this evening. 

Also got 1/4 turn on turbo clamp bolt, don't think this had any effect. 

 

Results are as follows :

Acrid smell is less obvious in the cab (think the smell is impregnated for now) ✅

Exhaust smoke at idle has pretty much disappeared ✅

Exhaust smell is 100% better ✅

Having fun driving (not dogging) no obvious smoke clouds ✅

Looking like this could of cured my cars problems? 

 

Next step. 

 

Order a replacement crankcase breather hose. 

 

Keep you all updated if anything changes. 

Looks like I'm going to be keeping my car for now 😊 

 

Thank you for your advice 👍

 

I would also like to mention that the hose seemed absolutely fine on inspection! Obviously it wasn't. 

 

Hope this can help anyone who may have the same issues.

Been AFK; that sounds like burning engine oil.
