Also if it was glowplug related or even fpr related im sure a code would come up on a scan absolutely nothing there. Car also does this when its fully operating temperature never when it's cold for first 10mins of driving. So don't think it could be glowplug related as it would be doing it when car is cold.

@Ecomatt i have had dpf removed/gutted i started noticing this issue alot more as soon as i removed dpf. Haven't changed glowplugs before car is on 107k now. Spoke with mechanic he said glowplugs don't need changing as you only use them for when starting car when cold and thats it and unlike petrol sparkplugs this wouldn't be the issue. Do you not think it could be fuel pressure regulator? As when the fuel pressure drops thats when it has a funny idle if you blip throttle its fine and runs fine when driving and sometimes when you come to a stop on idle its perfect sometimes it's not.

@Ecomatt car has been serviced. Funny you said about injector seals i changed all 4 seals and o rings on injectors last week they where leaking from seals. Still doing it. No codes come up have obd eleven. Put injector cleaner in problem still there.

@the_slug Did you find out what it is? I'm experiencing exact same but on the vrs diesel 2014. I have had a look at fuel pressure the fuel pressure drops when it starts to rough idle. If you blip the throttle it goes fine blip again it will start rough idling again. I have been experiencing this for a year now but it is starting to get worse noticed also when it rains it does it worse more often than dry. No fault codes spoken to a few specialists they are saying could be fuel pressure regulator haven't yet changed them will do soon and see how that goes.

Hi, My car has had high oil consumption for sometime. Never really looked in to it too much was consuming 1litre 1800miles now 1 litre every 700-1000 miles. I was looking for another problem on my car and i came across this which i am thinking is a pcv/ccv valve. Seems like theres oil all over the top of the engine where the fuel injectors are think this could be the cause of my high oil consumption. Anyone experienced similar also could somebody confirm this is a pcv/ccv valve if so whats the part number. My car is a octavia vrs 2014 2.0tdi engine code: cupa. Any help will be much appreciated thanks.

Is this a pcv/ccv valve? Can see oil around it and all over top of engine near fuel injectors. Have had high oil consumption for a while.

Hi, I have a 2014 skoda octavia mk3 5e vrs 2.0 tdi i am experiencing high oil consumption i have read this could be the reason due to it being stuck open/closed pcv valve. I have read some new cars don't have a pcv. Does anybody know if my car has a pcv?
