I topped the oil up today for the first time and saw that the oil was a bit yellow, but only around the oil filler cap, not the dip stick. The car is going fine. I guess this is just condensation?
Has anyone else seen this effect?
-
Anyone please! Anyone seeing anything different from the normal colour of oil?
-
I've never even needed to remove the oil cap in two years of ownership. Car hasn't needed oil but I looked last night and I don't have any yellow deposits. I was under the impression that yellow gunk in the oil cap was a sign of cylinder head failure on old cars. What's your driving style eg miles a day etc
-
Yes, yellow "mayo" around the cap can indicate head gasket failure, however, you also get small amounts when doing short journeys where the car doesn't get up to temp or really warm. It's just condensation mixing with oil vapour and nothing to worry about - though the short journeys with cold engine long term are not great.
OP: You do know that oil is a golden yellow colour before it's put into the engine don't you? :whistle: Doesn't stay that colour long in a diesel though....
-
I've taken a pic, but can't seem to upload it. The bright yellow coloured oil is only on the oil filler cap. The car has been mine for about a month now and serviced by VW before l took ownership.
The colour of the oil on the dipstick is as expected.
I have done some local drives and long motorway drives in this time engine oil temp and water temp have been fine, nothing unordinary. I have given the car a few squirts but again nothing prolonged or what l would call hammering and certainly nothing that would lead to a failure.
I have a longer drive this weekend, hence checking the oil level, which indicated it needed a slight top up.
If any of you don't mind, if you could PM your email address l'll send the photo over for your opinion.
Thanks

Just upload to photo bucket them post the img link, I see from your other post that your already running a dtuk box?
-
This is what it looks like, l have also emailed the dealer.
I am running the DTUK box, although my driving has been sensible since fitting it, l do not put it down to be anything connected to the box or my driving.
I'll be interested to hear your responses - l think :undecided:

What does the liquid feel or smell like? Is it oily or sticky? Does it look like melted cheese?
-
Thanks for responding so quickly.
Feels like oil, l didn't try smelling it, but l can't remember it smelling either.
It doesn't look like melted cheese, it looks more like an oil which has some neon yellow colouring in it..

If wiped away does it return & if so how quick?

Just checked mine and its black oil as you would expect and only serviced 3k miles ago. Is the rubber seal ok on the filler cap and does it fit quite tight?
-
I would have expected the oil to be blackish aswell, mine was serviced less than 1k miles ago. The rubber seal is in place and looks ok and the filler cap is as tight as l would expect it to be.
I have just returned from the VW garage where a member of their service department took a look and said he had no concern with regard to the oil feel, however the colour of the oil is strange, he believed it was just condensation. He cleaned the filler cap and said it should stay clean for a few weeks, however after carrying out my 6 mile drive to return to work, l checked the cap again and it was as it was prior to being cleaned (just like the photo)...
I have informed VW again, who are due to take another look this Friday. I'll provide feedback.
Any other ideas what could have caused this, the car has been mine now for about a month? If they can't identify the issue what would you request them to do as l would class this as being abnormal and that for an expensive car it gives me no peace of mind?
-
Ok well 6 miles is certainly not going to help with regards to heating the engine oil up and even more so in the winter months. However I would expect a more cream cheese type of substance if it was condensation.
If it was my car I would do either of these:
1. Take a sample of the current engine oil and get it analysed for water, fuel contaminants etc
2. Do a complete engine flush and replace with new correct oil & filter, then monitor
I would imagine VW would under take option 2 being the easiest & I would express my concerns to the service manager both verbally & in writing. Just in case of any quibble if you have a warranty claim
-
Thanks again OP,
I have written to VW, who to date have been very good. I have documented what has happened with my concerns etc.
I have a session booked for this Friday at 1pm, when l know the outcome l'll advise.
Thanks again for your help.

Mine goes in tomorrow for a gps / nav issue with lots of evidence :smiley:

I agree, certainly doesn't look like the normal stuff I described. It's a surprisingly vibrant yellow!

VW thinks its a faulty oil filler cap, its going in on Friday for an inspection, l hope they are right, but l'm not convienced..

It's a possibility but faulty as in what or how ? Unless it has a hairline crack but I can't see how that would cause such a yellow colour ? If the dipstick oil is black then it has to be something mixing with the oil at the filler point? Have you removed the tuning box cleaned the cap and run the car as totally standard?
-
The filler cap, looks good as does the filler cap seal, it also shuts off tight as l would expect, l don't see this being the fix. I removed the tuning box and have seen no difference in the amount of yellow stuff being built up.
I think if it was anything to do with the box it would have been well documented and l haven't hammered the car since fitting.
Hope your Nav issue is resolved.

Thanks mine should be easy I have all the info & pics with it putting me in the wrong place compared to my iPhone Nav, I also have a full copy of VCDS :smug: they have already ordered a new shark fin. Easy for VW to fit a new cap & test but it is puzzling. The other thing is perhaps the wrong oil was used at the service
-
Why did you need to top up the oil if it was only serviced 1k ago? These cars should do at least 12k min before any top up is required. Mine is still on max after nearly 4k since oil service
-
Your right, l forgot to mention that when l spoke to them, but they will have an email in the morning to document that. They did say expect to see some oil burnt during the first 10k, however to lose some in less that 1k isn't right either.
This idea sounds more plausable.
-
Ok Chris lets rewind a little is the car brand new from VW and your the first owner? If so what's with the oil service? Or are you a second owner like me with a car still under warranty?
-
The car is new to me but not new, l am the second owner. It is a 64 plate car with 8k on the clock. I bought it from VW direct. VW said they serviced it prior to me taking ownership.
I was hoping to put my new Milltek Exhaust on it tomorrow, but might hold on that for now...
If they have put the incorrect oil in it, it makes me wonder if that might have caused excessive during that time, but l guess that will be hard to prove.

Ok same as mine 64 plate but I purchased at 13k when it was also serviced now showing 17k with no oil loss. A word of warning while the car is still under warranty do not change it from standard as any mod may give them cause not to honour any warranty claim, that includes exhausts
-
Some engines do and will burn oil and at vastly different rates. My gtd has never needed a drop in two years and has also never had yellow crap under the oil cap either and i do 3 miles to work and 3 miles back. If its been serviced at a VW dealership then its unlikely they will have used the incorrect oil as all diesels use the same long life oil now. It might be worth asking VW for any previous service history or previous dealer visits to see if the previous owner has had any issues. You never know but it might be a major issue that the previous owner had.
-
My GTD does about half a litre of oil about every 8k miles or thereabouts.
Oil cosumption is definitely a factor of how you use it (big long motorway drives or small daily commutes)
I'll have a look at mine in a sec and see if I've got the "yellow peril" - can't say I've paid much attention when I've been tipping liquid 24 carat gold Castrol oil into it - I'm usually too busy grimacing at the price!
-
I've managed to arrange a meeting with the After Sales manager, whilst the car is being looked,at, l didn't think about previous issues, but l'll certainly raise the point - thanks.
-
Colour could stem from dealer using castrol professional oils.... they have dye added in...
-
It seems the Castrol Performance requires a UV light, however it could be an oil dye to help source an engine leak.
-
I forgot to look last night, but have just looked.... nope, nothing yellow there at all.
How long ago did your car have an oil change though?

I think it was only 1k ago according to his previous post
-
Had the session with VW, they have changed the oil filler cap and the rubber seal on that seems a few millimeter heigher than the previous.
I've done about a 15 mile trip and checked and it appeared as you would expect with no 'yellow peril'.
I've got a long drive this weekend so will give it a good test and l'll report back, hopefully this is the fix.
-
Let's hope so as it's a nice simple fix and nothing serious :cool:
-
Drove just under 500 miles this weekend and no signs of the yellow peril, seems the faulty cap was at fault.
Thanks for your help guys.
