Opinions wanted.. Oil leak noticed after 1 month of purchace from dealer.

[utensil999]

Good evening all,

Im after some opinions on my situation. One month ago i purchased a second hand 2013(registered 2014) 2.0 tfsi A4 quattro from a reputable honda dealer with a 3 month rac platinum plus warrenty. The honda dealer said it passed its 100 point check including checking for fluid leaks so it was good to sell to me. It has 52k on the clock. I bought it knowing it needed a service so took it to someone local to me. They have told me it has an oil leak. I have emailed the garage that sold it to me and i am awaiting their reply.

I would like some opinions on to what my cause of action should be?

Attached is a photo of the leak taken from underneith

Thanks in advance

It can be difficult to spot oil leaks on these cars with the plastic covering underneath. That said, they should know what they are looking for....I suspect the 100 point check wasn't particularly thorough. Either way, in your shoes I'd be going back to the dealer to claim under the warranty!

I wouldnt expect to be seeing oil leaking from a 13plate car unles its been blown up- yeh ok over the top- seals do go,but usualy only after starship milage or been Thrashed, any oil at top of engine-breather etc, weeps from rocker cover ?? a very little oil go's A long way when it gets hot--If you know what I mean !! But If it were me----the car would already be back where I got it from !!!

You can get an oil leak anytime. I agree that you shouldn't expect to see any, but that's still 4 years. I had a leak from my oil cooler which was dumping oil all over the plastic cover under the car. Didn't see it until the EGR valve got changed, and that's in a 2011 car with 60k miles on the clock.

oh I kmow what your saying, I run a we 03/ a3 asz 130, and the only we bit of oil I started to notice is just starting to weep from the TIP(turbo inlet pipe)-but i still have crankcase breather hooked up so thats where that is coming from-car has done 240.000 last 100.000 on sunflower oil only-we bit of pump stuff when it realy cold but othere than that all is well

[mhurer]

My 2008 2.0TDI had also had a small leak from the oil cooler back in 2013, and that was with only 30k miles on the clock.

Wait[emoji23][emoji24][emoji23][emoji23] you mean to say you put sunflower oil in your engine and it did 100.000?hahahahahah

Guess sunflower oil is a thinner viscosity than veggie oil ?

I did kill a Peugeot 1.4 derv pump on pure veggie , it used to diesel knock till warmed up a bit .

Wait we're forgetting peanut and coconut oil which taste better.

[Vagnuts]

No I meen "I use sunflower oil to this day and the car runs great-quieter exactly the same performance wee bit beter MPG-infact better since veg oil has a higher cetane number than the pump stuf"-(yeh check that fact !) and at £4.50 for 5ltrs from tesco- am saving a fair bit coin !! for the last oh---25yrs I'v been using it in all my oil burners-no pump, injector, or any other probs, apart from the fact that the first coupl tank fulls ya will need to chenge fuel filter-caus it cleans the the hole system tank and all. My last MOT smoke reading was 0.02 and that was a cold engine !!!:biglaugh::biglaugh: down south I believe asda has the best deal on veg--but if you find a chinese supermarket or indian-they use loads so its very cheep- I should mention that the CR's dont like it neet ya have to thin it out but the diesel was first desinged to run peanut oil !!!

[Vagnuts]

yeh the old oil burners had indirect injection, combustion chamber in the head-so piston crowns were flat- asfar as vag-since the direct injections-piston crown has recess whitch is the combustion chamber-less chance of unburned oil bypassing the rings an contaminating the engine oil !!!! A lot of foke told me I would knacker my wee PD iether injectors of full engine--but they were wrong !!!!!! I even run my A6 2.5 V6TDI on it, cheep as chips.hahaha

[Vagnuts]

hahaha, you are so funny as it seems you dont know what a diesel car actualy will run on, peanut oil was the first---I'v had my oil burners run on hydraulic oil before today with no problems,needs thining out a bit tho:D:arms::arms:

Honestly does veggie oil work on a car or your just entertaining us here? I wanna try it but I'm I don't want to disassemble my engine changing the piston rings! Does it smell like chef Gordon's kitchen?[emoji23][emoji23]

yes as i'v said in other posts it get a wee bit of the pump stuff in the coldest of weather--yeh read a 2 to 1 mix veg/sunflower to pump only wen its below 2-3ish% :biglaugh::arms::arms:

[Vagnuts]

what car have you got ??? if it is a direct injection tdi the piston crowns are recessed(thats the combustion chamber -the old ones had flat piston crowns combustion chamber in the head- so there was a chance of oil contaminating engine oil)---take note---the CR-common rail systems do not like pure veg/sunflower oil it needs to be thined down !! but yes I am not joking !!

If its fresh veg/sunflower-not realy that much smell-if its old used them yeh a smell of burger-chips-or what ever its been cooking-and when I use old stuff it gets filtered throgh an old pair of Levi's----no joke !! leaves mor coin for:beerchug::beerchug::biglaugh:

Do you put in just the veggie oil or you mix it with the diesel?

Sent from my iPhone using Tapatalk 99.9% of the time I run 100% veg/sunflower oil, when it get cold the veg thickens so need a wee bit thining out, but if the engine is warm to start with no thining needed, just put pump fuel in before ya stop it, if its going to be cold next time you go for start !!! usualy in realy cold weather I would put a two to one mix--two gallon veg to one diesel !!!

[Vagnuts]

but the VE engines I used 100% all time, never had a prob--even in the coldest of weather !!!

[Gazwould]

I've used veg ( rapeseed ) oil as I said earlier , absolutely fine but I think the viscosity when cold killed the crude '96 mechanical fuel pump .

I guess the 1.9 PD's have a pre heating of fuel to make it thinner in viscosity ?

Both veg and sunflower seem the same viscosity and the same energy content . Not a huge saving when bought by the litre .

I'm not sure what you mean by it cleaning out the tank and fuel system as I'm sure pump diesel has added solvents , detergents and dispersants , the stuff dissolves tarmac !

Does sunflower or veggie dissolve tarmac ?

I'm an avid user of 2 Stroke oil in derv .

I'm an avid user of 2 Stroke oil in derv . at the mo- I save one pound per gallon-the old CAV/Lucas diesel pumps would give up the gost with veg oil--but the Bosch pumps I have never had a prob with--no my 1.9 pd dont pre heat(only reciculate from filter untill up to temp them it opens and returns to tank via a we heat exchanger under driverside be4 back to tank-sunflower is thiner !!-becaue its thicker than diesel-it drags all the crap from the tank and lines(thats why I said after first two tanks ya need to change the fuel filter!) cleans the tank and lines--diesel from the pump is not as clean as foke think-(take you fule sender out and give you tank a scrape and you will see what I am saying-veg abd sunflower oil is -what it says on the plastic bottle-vegetable matter- not petroleum- no cemicals so no carbon etc etc-so no crap build up in you engine--is it startting to make sence ??--no I.m not trying to be a t--t just trying to make a point !!!! ps I have never heard of the 2stroke thing--but be ashured I am going to try !!!!:beerchug::beerchug::biglaugh::biglaugh:pps-next time you change fuel filter--have a look at just how black/dirty it is !! and that is just from pump fuel !!!

[Gazwould]

Surprised you haven't heard , it has to be mineral based JASO FB spec .

Semi and synthetic FC and FD don't dissolve well in the fuel and are more expensive anyway .

The oil brings additional lubricity to the pump and detergents and dispersants to keep the fuel system clean .

Being a petrol additive it must burn like petrol so it's molecules are first to ignite under diesels compression ignition then the diesel molecules follow , so this reduces diesels ignition delay ( diesel knock ) thus improving the fuels Cetane number .

The results are , quicker starting particularly noticeable from cold , quieter engine mostly noticeable at idle , less smoke out of exhaust as better combustion . Less carbon deposits in egr , intake manifold , turbo , etc .

More mpg , only a few .

You'll need more than just 100ml to a tank .


10 Litre Diesel ---> 50 Ml.
20 Litre Diesel ---> 100 Ml
30 Litre Diesel ---> 150 Ml.
40 Litre Diesel ---> 200 Ml.
50 Litre Diesel ---> 250 Ml.
60 Litre Diesel ---> 300 Ml.
70 Litre Diesel ---> 350 Ml.
80 Litre Diesel ---> 400 Ml.
90 Litre Diesel ---> 450 Ml.
100 Litre Diesel ---> 500 Ml.

Are you egr disabled ?

When you quote an mot smoke opacity reading of just 0.02
( lower than an actual reading of a dpf equipped car ) is that opacity mean value or just the lowest result ?

I understand you put in some pump derv when it gets really cold , it's what taxi drivers do but put a splash of petrol in the derv tank , I understand as it's more combustible thus reduces the diesel knock .

[Gazwould]

The 2 Stroke some have reported a halfing of the smoke opacity test , less smoke , less soot for a dpf to deal with .


There can be no doubt this is true as today I've just looked back at all the Boston print outs since 2011 , the first 3 on 2 different machines are almost 2.00.

From 2013 on the same serial # machine we have nearly 2.00 , 2014 1.50 and thereafter around 1.00 one is 0.94 , this corrosponds with my occasional then total last 3 years
2 Stroke usage and therefore is conclusive :D

It's going to be close on the Boston with dad's now dpf less 1.7 euro 5 common rail as after 20th May the limit will half to 0.75 .

Time for 2 Stroke !

[Vagnuts]

the veg has a higher Cetane number than most pump fuel asda-tesco ect-(may be shell is a bit better)and if it has not been processed into bio-then the Glycerin is still in it which is used as a lube in thousands of products,--if you are looking to boost the Cetane number in you fuel try this--Millers Diesel Power Ecomax-- used it loads of times and it do's what it says on the bottle !! re smoke test 0.02 is the highest it has ever been across the board-and I think that is because I still have the crank case breather hooked up--veg is not a petroleum based fuel no cems etc- so no carbon at all and no carbon build up in any part of the engine !! ps-a petrol additive will not boost the cetane number of diesel !!!!

[Gazwould]

Yes it will !!!

I saw a test with cetane boosters some worked some didn't , 2 Stroke did , by adding a petrol like combustible product it acts as a catalyst where the 2 Stroke ignites first then the diesel molecules follow thus reducing ignition delay , how else do you explain many over the world observing , better cold starting , smoke opacity halfed , quieter smoother engine.

See these 'Stop smoke' diesel products in motorfactors ? Well they're kerosene based which is more ignitable than diesel so same cetane boosting principle .



Millers Ecomax is good as is Diesel Rhino but they're expensive for small amounts , bulk is best , 5L of a genuine Cetane booster is 2- EHN , now I'm going to be very worried if you've never heard of it .

Peeps also combine it with 2 Stroke .

Had a quick look at sunflower oil and it's too far out for me , 14 times viscosity than diesel at 0 , cetane number at 40 where as ideal is mid to high 50's .

[Vagnuts]

I will def be trying the 2stoke just to compare !!! that linke fot 2-EHN I'v had b4 the stuff realy works, as for cetan numbers every car can be different ie-it trial and error to find what your can likes--if you know what I meen !!

It was quite awkward to find a cetane number , it was an old 1982 paper but sunflower oil is sunflower oil .

I'm not going to swallow all the info as it's 1982 but some must be relevant .

Sunflower oil has emerged among the vegetable oils as potential fuel alternatives. The Province of Manitoba is the major producer of sunflower oil in Canada. This study was initiated to investigate the fuel-related physical properties and performance characteristics in compression ignition engines. The results for sunflower oil were summarized and compared with No. 2 diesel fuel. The most detrimental parameter in the use of sunflower oil is its higher viscosity which is about 14 times higher than diesel fuel at 37.78/sup 0/C. The problem of higher viscosity can be solved by transesterification of sunflower oil to its methyl ester. The cetane number of sunflower oil is a little less than the minimum value of 40 for No. 2 diesel fuel. Specific fuel consumption was higher due to its lower energy value whereas thermal efficiency was satisfactory when compared with No. 2 diesel fuel. Oxidation of sunflower oil left heavy gum and wax deposits on the stationary engine parts and the test bench equipment. Lower levels of corrosion can be expected on metal parts due to the lower sulfur content in the sunflower oil. Fire hazards associated with fuel handling will be reduced because of the higher flash point of sunflower oil. 5 figures, 4 tables. (DP)

..High viscosity can lead to injection problems, poor atomization and incomplete combustion. While the vegetable oils do not have good properties on injection and ignition , they have high flash point and provide advantage on storage safety678. Besides the transesterification method was widely used in order to remove the negativities arising from vegetable oils, pyrolysis, microemulsion and refining methods are also used9101112. ...

Thanks for the info--I know its thicker so dosnt atomize the same-untill its at 70degrese) but as iv said i have been using it for last 25yrs in all my diesel cars with no probs what so ever. try ten or twenty ltrs in you car without the two stroke and let me know how you get on !!

[utensil999]

Hi, I finally got to the cause of the leek which was a leak in the lower timing chain cover. It was running down the front of the engine block covering the sump, oil sensor and atf pipes. All seems to be dry there now. And work was all paid for by either rac warranty and or purchasing garage. After a little tooing and frowing and citing my right to reject the car under the consumer rights act.
