And yes, oil consumption's at 1 liter per 1,800 miles now (rising to 1 litre per 1,000 miles if I put Castrol Edge in!!). That's at 150k miles on a CUPA TDI 184. It's definitely burning it (exhaust fumes stink of oil on acceleration) and the turbo/inlet are as dry as a bone. Seems to be a problem with the oil scraper rings clogging on this engine; the oil drainage holes are tiny and seem to get clogged with soot. I'm going to try putting some ring cleaner jollop through the glow plug bores and set up a new thread on it if it works...

I only used castrol on my one once in 211 k miles was using 1L 1500 miles...changed it 3 weeks later... i would use either the quantum 5w30 504.00/507.00( is also done by bp like castrol should) or what vag has as genuine: GS55545M4EUR it replaced the 5w30 about 3 years ago but funny enough i could not get it at dealerships.

Another cause for oil consumption could be valve stem oil seals exhaust side, or at least i would look at those before pointing at piston rings; tho do to the work involved ...

Thanks! I may well give those a go. Thanks for the suggestion of the valve stem seals too. I suppose the turbo/DPF back pressures help to reduce leaks like this, but if they're very worn this could be the problem. I have no inclination whatsoever to work on this engine ever again though (at the moment)... hideous. Does VCDS give you a hint for the login code for the adaption? I think mine might have done. Unless it's the standard 12233 used on older cars?

Hi what vcds sugest in the hint baloon is 12345 which is not accepted, however 17575 works is accepted and was ok for me to do the other adaptations, but once i try to do the ash adaptation i get a error do to security code. This is the procedure i used:

It is S12345 and the upper case S is important.

**Ben_T** · 30-08-2023,12:31 PM

I didn't see Crasher's post so I thought I'd re-trace my steps - S12345 works on my Ocativa. Hope the same's for a Superb

**N871BUD** · 30-08-2023,02:22 PM

Cheers for that, i am pretty sure i did check that before but seems indeed being a S instead of s an i ve must of not used upper case.

Ash adaptation complete down to 1.00g.

Will update later on with how long it takes from now on in miles to regen.

**N871BUD** · 09-09-2023,03:55 PM

Hi, time to update i gues 930 miles driven since changed with the clean one and about 700 since i managed to reset the ash... it got kind of hard to catch it doing a regen ... as it seems it happened only 3 times so far... ash content is displayed after almost 2 weeks 1.2grams and 700 miles.

Having a bit of headache to get the wheel aligment done after i dropped the subframe tho so if anyone atempts this make sure you have a place willing to slacken the subframe bolts to get the aligment right on the front. in the end i have a slightly more negative camber - 1˚ 14' and slightly of caster 6˚ 21' on front lefthand side.

Or use subframe pegs

That's sounding good! If you don't mind me asking, do you know how much oil you've used in that mileage?

No joy with the piston ring cleaning for me - I tried spraying injector decarboniser through the glowplug holes, leaving to soak for many hours with the occasional hand-turn of the crank to help it work its way down. I could only do two cylinders (one glowplug snapped and couldn't be removed, another was also seized), but the oil consumption's the same. I was hoping it might halve at the very least!

Not sure what exactly your asking but...

Since last service i topped up 600ml and now i am 3/4 between maximum and minimum on dipstick.
I have left 3500 miles till next oil change now.
My service interval is set to 9400 miles and i ussually do the oil change at about 8000 miles (i get annoyed of the message i get when it gets close to the oil change).
I replaced the dpf after the oil service at about 2500 miles if i am not wrong as i had 207k miles when i done the crankshaft seal and dropped the oil sump.

Before crankshaft seal and dpf replacement i was using about 700 ml for top up between oil changes every 8000 miles or so. but that was to keep it somewhere between 1/4 to 3/4 full on dipstick;
I think is more acurate to say that if i do a oil change and oil is in maximum on dipstick, i will top up at about 4500 miles after the change with 600ml to get it to 3/4 and at the next oil change would be close to 1/4 or just about and would need toping up but i do not care at that point as i am doing a oil change.
To be fair as i am doing the oil change i did not check to see how much i would actually need to get it up to the mark at that point.
I noticed while i had dpf off to put the clean one on that i have a slight play in turbo shaft, small but there... so i might lose a tiny fraction of oil through there maybe?
I also still have a oil leak, very small on the rocker cover around left back corner, around the bolt but that is minimal as i get some oil i suck it up with a corner of tissue every 2 weeks (not worth for me to pull injectors off and replace rocker cover gasket just yet as it very small).

Since dpf change i do not know what difference it makes in oil consumption but so far i would say it does not. The only thing that seems it affected oil ussage was the crankshaft seal sipping oil doing a mess in my undertray.

As far as i know on the tsi was a thing with oil consumption because of piston rings and the actual design of the pistons. So i pretty much doubt that is your problem.
Sorry to hear about your glow plugs did not had a issue with getting my one off at 125-128k miles with engine hot no problem tho i was worried as one is with pressure sensor.
