D5254T (to 2002, Audi) Overfilled sump - bad starting problem

[smle]

Hi Vincentvg

Recently bought a S80 with the same Audi Diesel Engine, (2001 Reg), decided to change oil, added recommended 6 Litres, checked dipstick and the level was about three inches above full mark. Then drained oil to check the amount I had added, there was 6 litres right enough.

Verified from Volvo spec (VADIS) that 6 Litres was correct, and decided that something else was wrong.

Checked the parts list in VADIS and noticed that TWO dipsticks were specified for that engine.

P/Nos. 9180736 and 9497470

Can only assume that somehow the wrong dipstick has been fitted.

I would strongly suggest that you have your garage drain your engine and refill with 6 litres.

As to the stumble when warming up, since it starts and runs ok I wouldn't worry about it, put it down to its age and modern electrickery. Mine does the same.

BTW I recently mention the dipstick problem on the S80 forum but nobody responded.

I was thinking of asking at a Volvo dealers to view the two dipsticks (Eventually)

This leaves more sludge in the bottem of the sump !! A very bad idea, even if you run the engine till its hot there will still be more crud left in the sump than if the plug is removed ,as the oil flows quicker .
Only my opinion as an ex engineer of 35 years .

Yeah - but the idea is just to remove a couple of pints - to get the level back where it should be. I'm not proposing to change the oil using this device: not least because I've only just had an oil & filter change less than 2K miles ago (the reason for this thread, and the cause of my distress)!

Surely the most important point here is having the correct amount of oil in the engine??

If you add the correct amount (in this case 6 litres) and the dipstick shows very high with the car on level ground there is something wrong with the dipstick.

I don't know why you are taking more oil out. IMHO either you or your garage must verify that only 6 litres have been added and make a note of where this appears on the dipstick and in the future maintain this level.

If not you risk a ruined engine.

The dipstick is the original - I've owned the car (and its dipstick) from new. The dipstick is correct: it's the amount of oil in the sump that's incorrect!

If the engine sump capacity is 6 litres, that will be with an unfilled engine. However a Volvo engine that has been filled previously, when drained, will still hold about a liter of oil in my experience, unless you leave it to drain for 2 to 3 weeks. Thus if you put 6 liters in it will be well overfilled. Probably what happened in the first place.

My XC90 with a D5 engine handbook states to check the oil level with a cold engine for the most accurate reading. I've found the oil level shown on the dipstick will still continue to rise for 3 weeks though if the car is unused.

Exactly! Thanks Roy

I havent read all the posts, but Overfilling a diesel engine with oil can be its last days work soon if not rectified.
The engine will go into runaway, ie. just rev up, up, up and away it goes to the breakers in the sky, happened with various diesels about in my and other peoples ownership, fortunately the Beringo I was driving just blew all the vacuum pipes off and ejected most of the oil itself while I was using the 'runaway' to drive back to the shop. (I overfilled it due to a profuse oil leak)

You have been warned!


(will read the rest of the posts)


IMHO, Get your money back off the service agents for attempting to **** up your engine.

My owners hand book states that if you do an oil change and use the 6litres of oil recommended then the level will be half way between the upper and lower level marks on the dipstick

My 2003 handbook which covers that engine as well as the D5, dosn't give any infomation on changing the oil only checking the level. It does give a capacity of 5.8 litres but that will be with an empty engine. Once a Volvo has had oil in it, it will always retain a suprising amount. My various Volvos have held between one and one and a half liters. One of the handbooks for my old Volvos which had more servicing info used to comment that a certain amount would be left in the engine. (Might have been the 245, but could have been the 940)
