Oil lamp on with low rpm 1.8t aeb

[Audi Norway]

Hi! When the engine is hot andre I drive with low rpm, aprox 1000-1500 for a few minute, the red oil kamp blinks andre IT giver a beep sound. IT gies away if I drive with rpm on 2000 or higer I few sec. IT Comes back after a few minutes if I drive with low rpm again.

For a little White ago I used motor flush.

Amy tips ? Take of the bottom Pan ans clean a filter inside Therese maybe ?

[zollaf]

don't use the car until its cured. the flush has probably knocked a load of crap out which is now in the sump. so, sump off, clean, etc...

[Audi Norway]

Thanks for answer. Do you have a guide to take off the oil pan ?
Is it hard ?

[zollaf]

drop subframe, remove sump.

[Audi Norway]

Thanks for answer. how does i drop the subframe the easyest way ?
And the bolts for the sump, is they hard to get ? Did see a video from A4 and there they needed to crank the engine to getting to two bolts in the gear box ?

[amiram]

Did you replaced the oil filter, after you made the engine flash?

[Audi Norway]

Yes I did. And the oil did not see very dirty too.

Can it be the oil pump?

[zollaf]

there are a couple of bolts hidden at the back where the sump joins the gearbox. they are a bit fiddly to get to and you will need a small 10mm socket on an extension or a 6mm allen key , a long one. you turn the flywheel until you can get to them. the subframe needs lowering, just undo the mounts and lower it but you then need to align it when it goes back in.

[amiram]

It's an option. But I suggest you go from the easy to the heavy. Check whether the engine oil is not too thin (flash material residues). In the oil system has oil pressure release valve If it is stuck this can Cause similar results. How many miles \ KM on the clock?

[Crasher]

It will be crap in the sump as Zolly says, playing around with other ideas is like playing Russian roulette with your turbo at the least. The sump will need to be cleaned out and for this I use paint stripper to avoid damaging the sumps shiny surface which helps reduce the dirts ability to cling. The inside of the cam cover and head will also be covered in sludge. This is why I always warn people about oil flushes, they can cause more problems than they solve.

[Audi Norway]

Thanks for anwer! my oil is 5W-40 and has Vw 502 spec. Changet it for a mount ago.

This problem did not come right away after flushing, but after a couple of weeks or so. It is getting worse, in the begeanning i did just get the warning once and it was gone right after. Now it is every time the car is hot on low rpm.

The workshop say they have changed the oil pump on many of that car, so maybe i should change that ?

The car has gone 222,000Km

I dont think i have time to change the oil pump and clean the sump, so i think i am going to the workshop so they can change it and clean the sump.

But before i do that, is there some other ting i should check ?

[ametlib]

Yes, check if you can find a garage that will only pull the sump and clean the oilpump pick up. The only reason they wants to change the oil pump is because half their income on that job comes from selling you a new oilpump .... ( wich you really dont need)

[Audi Norway]

there are a couple of bolts hidden at the back where the sump joins the gearbox. they are a bit fiddly to get to and you will need a small 10mm socket on an extension or a 6mm allen key , a long one. you turn the flywheel until you can get to them. the subframe needs lowering, just undo the mounts and lower it but you then need to align it when it goes back in.

Ok, do you have a pic of witch mount bolts i need to take out ? And i dont need to support the gear box or the engine when i lower the sub frame ?
Maybe my dad is gonna to try to do this job next week while i am on work away from home.

And what do you mean by align it ? Just so i can get the bolts in or do you talking about alignment with messuring tools or so ?

[Crasher]

As Ametlib says, you won't benefit from a new pump and all you need is a new pick up tube BUT you can'tr buy the pick up tube for an AEB without the pump so I think it would be best to find a Febi 19416 which you should be able to buy for around the equivalent of £80 THE critical aspects are getting the sump clean whilst maintaining the shine AND applying a perfect bead of just the right amount of VAG white silicon goo.

KLOKKERHOLM in Denmark offer a new sump without sensor which is no longer available from Audi and this would save time and ensure a perfect finish.

" AND applying a perfect bead of just the right amount of VAG white silicon goo."
Well said! I once pulled the sump on one of this just to find the pick up clogged up of pieces of silicon !!!...........

[Crasher]

Yeh, but I'll bet it was not like this!

I have now ordered a new oil pan with oil level hole and a cover for that hole, and a new oil pump.

But i cant remove one of the oil pan bolt. It is loose but i cant take it out, it crash with a bracket in front. DO i need to lift the engine, or take off the radiator assembly and then the bracket ? :O

[Crasher]

That is why pro's have ball ended hex keys.

[Audi Norway]

I do have ball ended, and can screw it around, but i cant screw it out, because it crash agenst the pracket you see on the picture. Do i need to screw that bracket out, or is it another magic trick ?

[Crasher]

You have to remove the AC tensioner, engine reaction mount cup and the plate behind it.

Ok, so i need to take off the radiator stuff then, hehe. Thanks.

[Crasher]

Not exactly, you remove the front bumper and fit long pegs into the cross member and slide the car forward into the "service position", a bit like the missionary position but not as much fun. This is a picture, of the service position!

[Audi Norway]

Aha, so its enough to take the front carrier to service posison, that is ok :) Thanks.

[Audi Norway]

Have now manage to take off the old oil pan and oil pump. It was a few particles on the oil pump inlet, but not very much, but it was a lots of particles in the oil pan.

But when i install the new oil pan, can i use the old gasket ? It seams fine. I think i can use the old and a litte bit of silicone ?

[Peter D]

There is no gasket there it is a silicon bead. Please explain the particles. Particles of what exactly. Was the pick up tube blocked. ? Regards Peter

[Audi Norway]

It does seams like a metal-rubber gasket, i also see a online shop that have a gasket for the oilpan to my car, see the link:

https://www.skruvat.com/Gasket-oil-pan-P18932.aspx

The pickup tube is not completely blocked, just a few particles. You can see the pickup tube and the particles in the oilpan on the pics

[Peter D]

Look at post #14 from Crasher. That gasket is not the right shape. What are the particles exactly. Metal, sludge, grit, what. ?
Is your sump the shape of that gasket. Regards Peter

[Audi Norway]

I am not sure what the particles is. I did sport a small metal particles, but the other one, i dont know. Some is orange and prossible to brake into small pices. Yes my pan is the size of the gasket, not the shape of the pic on post # 14

[Crasher]

The sump in my picture was front wheel drive, it was to illustrate the silicon. Ally sumps don't have a gasket, some steel ones don't either.

[Audi Norway]

ok, but my old sump did use gasket, the same as i linked to from Skruvat.com

What is your advice, should i just use the old gasket or take it out and just use silicon ? What can be the reason since there was a gasket on my car ? It is the original oil pan i think (audi wolkswagen logo on it,)

[Peter D]

Is your sump Alloy or steel. ? I think you need a replacement gasket. Regards Peter

[Audi Norway]

The new one is alloy. i am not sure but i think the old one also is alloy.
i talked to the audi delaer in norway, they said cars before 1999 used gasket, but cars after 1999 used silicon goo
