Octavia TFSi Oil Consumption

Featured Replies

Hi there folks i have recently bought a 06 vrs and it was APPARENTLY serviced when i got it. I know i checked oil when i got it it seemed to be fine (mind not that its easy to read how much is in with the plastic bottomed dipstick lol) now 3 months later oil seems to be on min is this normal or is there something wrong?

If so what could be at fault to consume THAT much oil.

Cheers in advance

Absolute normal mine used to use about a litre every month or so well documented on the forum, thats most Vw group cars.

I had a pd130 golf previous to this and that never lost any oil

Hence why i was a little dubious

Very different engine to the diesel golf :)

 

Yes an amount of oil usage is normal, mine is pretty good (only uses a tiny bit) and others are quite bad. I know the previous owner of mine changed a few parts (PCV) which helped hugely

PCV what is this mate not sure on what you mean

Try searching "TFSI oil consumption" on internet and you'll find plenty of topic about your problem.

Some of my colleagues had VW Golfs (04) as work cars and 2.0 petrol engines consumed much oil. These cars hadn't even high mileages but anyway once in a while that annoying oil indicator started flashing. However another colleague has got old Audi with the same 2,0 engine and it's oil consumption is almost 0...

2. Positive Crankcase Ventilation failure

Background:

The positive crankcase ventilation is supposed to let gases get sucked from the crankcase to the intake manifold when under vacuum. The problem is, when the pcv system fails, and allows positive pressure (boost) to go from the intake manifold back into the crankcase.

Symptoms:

-Typically you will see a slight drop in boost pressure. When my pcv failed, I saw a 2 psi drop across the board.

-Some oil will be pushed out through the oil filler cap, and onto the valve cover, and may possibly go towards the coil packs. There may also be some oil on the bottom side of the engine cover, where the oil filler cap is.

-There might be a slight decrease in MPG.

-Rear PCV failure usually results in oil accumulation around the DV, and will produce a little blue oil smoke at WOT applications.

Solution:

-There is the Digitalhippie fix which puts a check valve into the line from the crankcase to the intake manifold. For those who want a spare of the hose where the check valve is installed, the part number is 06F 103 221 F. You can read more about it here: http://www.golfmkv.com/forums/...=8952

-You can also upgrade to the latest PCV “G” valve. There have been very few failures reported with this PCV. Please verify the PCV you have before upgrading.

Part numbers for this upgrade:

PCV valve cover assembly: 06F 129 101 G

PCV valve cover gasket: 06F 103 483 E

PCV valve cover to turbo hose: 06F 103 215 A

PCV tube to turbo metal gasket: 06F 145 757 F

-If you did the DH pcv fix, and you have a rear pcv failure, then you will need to change the tube labeled as "Exhaust turbocharged gas outlet" showin in the pic above. the Part #'s are the last two shown above (06F 103 215 A & 06F 145 757 F)

Wow thats alot to take in lol will maybe look into it

Worth reading that thread generally, an older VRS will probably have at least one of those things wrong unless it's been done already - the diverter valve is another common one.

 

The previous owner of mine didnt have any noticeable oil being pushed past the filler like in the description, it was just losing it - after changing the PCV it's perfectly acceptable. He left me with half a 2L bottle of oil in the boot and that lasted about 5k miles.

 

Making sure the right oil is used is essential too - if you don't know exactly when it was last changed and what the oil was, get it done for peace of mind. Needs to be fully synthetic

After a little look about i noticed you can get a pcv delete are they recommended or not

Only if you want to monitor & empty a catch can every 2000km.
