Hi all,

 

Just wondering if anyone can help with a diesel oil engine for this car. Yesterday, I did the service myself for first time. Before that, I made sure that I had everything I needed and checked that this car has a 4.3l oil capacity including oil filter. My surprise is that after the extraction of the oil, I filled a 5 litre bottle and a bit more that needed to to to a milk bottle. How is this possible?? When filling the new oil, I put in 4 litres and after checking the dipstick, the mark was ok. I am kind of worry.....any suggestions? Was it overfilled? Do I need to put at least 4.3l?

 

Thanks for your help,

Regards 

Hi, welcome to the forum. Did you check the dip stick before draining - and did you replace the filter?

It sounds as if it was overfilled - or possibly there may have an amount of fuel in the oil. Don't overfill, only add oil until it reads correctly on the 'Full' line of the stick. Make sure vehicle is level and recheck level after a short engine run (allow sufficient time for oil to drain back to sump) 

PS. just noticed that you used oil extractor - that will usually leave a small quantity of old oil in the sump.

added note.

Two choices

 

Overfilled previously

Or the car is leaking diesel fuel into the oil

 

Can you supply engine code, not a CAYC is it?

How can I get the engine code? I have the VIN, but not sure how to get the engine code...

Thanks for the response. I did use a extraction pump. To be honest I was going to drain it with the normal method, but when I saw that I extracted 5 litres thought that was more than enough.... rookie mistake....the dipstick mark was all cover, even over the mark as well which is something I don't understand because after refilling with 4 new litres I can see that the dipstick has oil over the mark as well. Will try again tomorrow after the school run.

Your V5 will have it printed, or equivalent documents if not in UK.

The engine number is CAY 659686

There's a fair few threads similar to the above on the forum.

 

iirc CAYC engines like to eat injectors, leaking etc.  Not sure I have heard of CAY engine code, but could look.

That's what it appears in the v5c... probably it is a CAYC but clearly it shows CA in the v5c...

Just read few threads but not sure about if the year model cars are same as mine. It is true that my car's DPF is being a pain for the last few years, I mostly do small journeys in the city and only from time to time drive in motorways.....

Anything you guys advise me to do? Cheers

Last year you was asking about a diagnostic device that was capable of doing forced DPF regens.

 

What's the full story about that, the need for it and did you buy something in the end?  History with a car is very valuable to get overall picture of how it's behaving.

 

Lots of failed regens and short journeys will clog the DPF and can cause excess diesel in the oil.

The battle with the DPF is still on going. Took the car to the garage to resolve the limp mode and clear the dpf issue, but after that every 150-200mi the DPF light comes on again and makes me drive the car in the motorway until it clears.....but again, back to the routine (short trips) and the cycle continues....the only difference is that once the light comes on, I drive straight to the motorway

 

I know this car does not suit my needs as I only use it for short trips, but I dont want to spend a fortune in a new dpf or buy a new car.

 

The book history of the car looks good, it has been serviced every 10k miles. It is true that due to my low mileage use of the car, previous service was done prior COVID.

 

Thanks for your help!

Circling back to your original question quickly, the usual amount of oil is 4.3l with filter change, but you're always best to stop short and add some after turning engine over.

 

Measure and then top up if needed, so you don't have to put in exactly 4.3l.

 

 

Extracting the 5l was interesting of course, all I can suggest is to monitor it every 2 week's perhaps and of the oil is increasing, then if it's gaining liquid (likely diesel, as water would make it like mayo) you need to investigate cause.

 

Did you have any diagnostic equipment for the car (sorry if you mentioned, didn't see?)

I did not fill it with 4.3l, only 4 litres and the level after was over the dipstick mark...really weird. I would monitor the levels in the next few weeks and see if it is dropping or increasing.

 

I do not have any diagnosis equipment....used to have an ob2 but it was useful.

 

Thanks for your help!

Not sure I have heard of CAY engine code

There are three main engines of different power in the family. CAYA,CAYB and CAYC rising in increasing power. CAYA is in the Polo. Here is the full list of specifications:-

 

55 kW (75 PS; 74 bhp) at 4,000 rpm; 195 N⋅m (144 lbf⋅ft) at 1,500-2,500 rpm — CAYA (Polo and Fabia only)

55 kW (75 PS; 74 bhp) at 3,000-4,000 rpm; 225 N⋅m (166 lbf⋅ft) at 1,500-2,250 rpm — CAYE (Caddy only)

66 kW (90 PS; 89 bhp) at 4,200 rpm; 230 N⋅m (170 lbf⋅ft) at 1,500-2,500 rpm — CAYB

75 kW (102 PS; 101 bhp) at 4,400 rpm; 250 N⋅m (184 lbf⋅ft) at 1,500-2,500 rpm — CAYD (Caddy only)

77 kW (105 PS; 103 bhp) at 4,400 rpm; 250 N⋅m (184 lbf⋅ft) at 1,500-2,500 rpm — CAYC

85 kW (116 PS; 114 bhp) at 4,400 rpm; 250 N⋅m (184 lbf⋅ft) at 2,000-2,500 rpm — CEKA (Mexico only)

I know, it's in your first post that you put in 4l and it was on/over the full mark.

 

More to answer your question, that you was asking, you don't have to put in x.y litres, stop at 0.5l less or there abouts everytime.  Fire up engine, stop, let it settle and check dipstick etc.

Thanks, quite aware of the list... Point was, never seen a CAY engine code, always 4 characters like the examples you posted.

 

Suspect OP's V5 is a little off sadly.

Not sure for the Mk.2 - but there may be a sticker near the bottom of the B pillar with the engine code.

The sticker is near the spare wheel.

Your engine is CAYC. 

How long have you had the car?

Do you know if it has had the software update?

If it has, the regens of the DPF are more frequent.  Id say every 100 miles or so rather than every 300-350 miles.  Im sure there will be loads of threads on this. 

By the time your DPF light has came on, your car has already tried to regenerate a few times and failed. (software updated or not) and is telling you to take it for a run.  During every attempted regen, extra fuel is injected into the engine.  If this sequence is interrupted (when you turn the engine off & the regen fails) that fuel is left in the engine and leaks down past the pistons and enters your oil.  Hence the possible extra oil when you withdraw it. 

It is said that when using an oil pump, not all oil is withdrawn and a little is left in the bottom.  Dont forget to change the filter and get that little extra from where the oil filter goes during oil changes.

 

I see it was your first oil change yourself using an oil pump.  Well done 👍  It took me a while, but for the last 17 years now i have been doing these myself on a variety of cars with an oil pump/extractor.  As Warrior 193 says, use the amount going back in as a rough guide only.  You may as people say, have a little which cant be removed.  Thats fine.  Fill to the top level on the dipstick then start the engine for a bit, let it run through, only around 20 seconds or so, then leave it and check it again after around 30mins. Top up to the max again as necessary.

 

Enjoy your car, its a cracking engine if looked after correctly.
