I will try and keep this short. The vehicle has now nearly covered 140k in total.

 

At 90k the EGR valve was replaced due to it being faulty before any attempt of the 'emissions fix' update. Which really goes to show this part can fail before any reprogramming being done.

 

However this 23R6 recall was apparently abandoned for some unknown reason as when I took the vehicle in for servicing the dealer kept asking me if I wanted it done. (I declined) But Skoda UK records show as being completed. This is still being investigated at the moment but due to bad workmanship from this dealer oil leaks and 'misting' of oil was occurring at the back of the engine block and I was told all engines do this! Gobsmacked I got Skoda UK to cover the cost of a proper repair by another dealer who nailed it.

 

Now me thinking great no more oil leaks then boom oil leaking from what I can see from the inlet manifold stepper motor aperture for the swirl flaps and end mounting bolts. So I thought get the manifold gasket replaced. Got that done and still she insists in weeping oil! I have been given many excuses for example over tightened oil filter cap which may have a hairline crack or old oil residue and finally turbo getting tired causing blow by or breathing heavy.

 

I do believe this is not the case and it requires a complete uprated or modified assembly. The reason being is that I did read somewhere that the 1.2tdi polo's suffered fractures and VW modified them. I also spoke to a Seat Technician and he confirmed these are common across the EA189 engines across all manufactures who share this engine. He said remember that these are plastic and they get hot and cold and are renowned for cracking. I did remember that when in regeneration mode these engines reach 130 degrees plus! What I cannot understand is why didn't the Skoda dealer tell me this?

 

Has anyone on the forum come across this problem on their vehicle? I know this will be a costly repair and again I will ask Skoda UK aid with costs if possible. I have tried to find info on the site but its very vague and could only find some info on the 1.6tdi variant and any advice given would be greatly appreciated.

 

 

 

 

an engine with 140k on will breathe heavier, just a trait of engines as they wear and mileage increases.

 

Post a picture of where the oil is leaking from

Edited 28 September, 20196 yr by UrbanPanzer

As requested some pictures of the weep. I believe it occurs more so when boost is demanded. For example hill climbs. The oil runs underneath the inlet assembly and drops onto the oil filter housing. Apparently these engines are a bit dirty internally and there will be oil residue in the intake side but the garage tells me the turbo could be letting more through. Thanks again. 

Hi, Ambrosia

 

My  vehicle has  covered  90k in totaly.  (VW1.2 tdi 3 cyclinder)

I guess, I have same problems about intake manifold. When I drove more 100 km distance(almost hily roadl),  oil drop appeared on the  filter cap.

then i have been watching for long time after that   i realised that engine speed exceeds 3000 rpm, oil (bubble-like) leaks from plastic manifold edge(not much). 

As you can see in the following representative picture, as soon as possible i'll upload the real picture.

 

In this case, what would you recommend me to do? Thanks.

 

1) i replaced new  oil cap

2) I tightened the screws.

 

Did you ever figure this out?

 

I'm having the same issue on a 1.2 TDi Polo 2013. Same engine I'd presume, CFWA.

 

It seems like it's wet wround the "snout" where the "throttle body" sits. Maybe a bit more on the EGR pipe side. My main suspect is the gasket behind the pipe/coupling for the EGR pipe. Right now I suspect either the "throttle body" gasket or the EGR coupling gasket.

Photos for reference.

 

Same thing - wet on the edge of the manifold and on the top of the oil filter housing. But seems like it's more "recently wet" just around the EGR coupling pipe.

Has anyone ever found a solution to this? I'm experiencing the same issue.
