I've been having this problem for the past 2months with most mechanic unable to sort it out. I will now return to instruct them on changing this . I did some personal checks and found oil all over my oil sump. Thank you Thank you Thank you. This video is very helpful
@@Iosif.dumitru01 the longer you drive it the more you will loose. It’s not a big leak, but you could lose gallons of coolant if you just keep driving it. I personally replace the part as soon as I now it’s leaking so I’ve lost maybe a quart of coolant before fixing it.
I just looked under the car and there is no leak, The smoke from the exhaust is transparent. How do I know that is the oil housing to blame? It looks clean.
@@Iosif.dumitru01 , I wouldn’t start replacing parts until you can pinpoint the problem. If you’re not leaking coolant from anywhere I wouldn’t replace the oil filter / cooler housing.
Just found this same problem on my 2012 TDI. Smh I been trying my best to figure this out and now I see it leaking from the side. Looks like it's gonna be expensive and a hell of a headache. Thanks for the video!
You’re welcome. The first tricky part is figuring out where it’s leaking from because you simply can’t see it. Then the next tricky thing is changing it. It is a pain, but if you can do it yourself you will save a lot of money!!
I had seen mine leaking all around the intercooler, i didn't have any way to get it that high up to do your kind of examination, good to know oil filter housing is a common fail point on these
Thanks you sir I had the exact same issue the coolant window on the oil filter housing was deformed 100%!the exact same way this one was absolutely painful to do! But if you just have the proper tools anybody could really replace it
Gaskets yes, bolts no. Make sure you clean out the bolt heads and have the triple square security in the bolt. They tend to get full of crude. If you clean them out you will have no issues with them.
Looks like I have a leak from the oil cooler housing too. However, oil have filled my coolant tank up top. Should I go ahead and replace the oil cooler housing first, then suck the oil out the coolant tank. Then do a coolant flush, and oil change ?
Yes, I think that would be the best approach. Also when you get the old cooler off, insect it and try to confirm that’s the issue. It’s usually pretty obvious.
2011 golf/jetta tdi owner here. Car started to eat up coolant about 4000 km ago. It's really weird because it only happens about every 1000km or so. The coolant loss also varies, from 1 dl to half a liter. No other symptoms, no overheating, no warnings no nothing. I suspected some plastic seal surface gave out. Looks like this may be the issue.
Hi, great info, thanks. On a 2005 Passat TDI I changed the thermostat, since the car was in TN and not driven very much, I suspect that the thermostat was bad for many years. I did not touch the heater core ni ..pples as I know they break, so I would just let it burp out over a few days and top off with coolant. Then I had a coolant leak, couldn't track it down, finally checked under the cowling, it was wet, moved the clamp back so it gets on fresh hose, then still leaking and found the ni...p1e was cracked. Bummer. Dashboard out repair. Bypassed that with the U shaped Dorman hose, still leaking but a lot less. So I guess putting the old parts up to 190 degrees and I maybe more pressure caused two failures. Put some dye in it. I see a leak under the engine, basically straight down from the center rear of the engine by the firewall. Any guesses on what that might be? Thanks.
You're welcome! Unfortunately, it's hard to say without looking at it. All I can really give you is general advice. I don't believe there are anything but heater hoses back by the firewall, but you will need to pinpoint the leak before replacing anything. Try to find the highest point that is wet with coolant, then look around that area. The only thing that could complicate that method is that sometimes a coolant leak can be a pin hole in a hose that sprays out when under pressure and soaks a completely different area. It can absolutely be a pain sometimes to pinpoint, but then you get if fixed right, without replacing good parts. Best of luck with the repair!!
I can’t say that I’ve looked for one. I have looked for an all metal housing and I haven’t found that. That would be an awesome upgrade if someone did make one.
I’ve replaced this part and it did fix my main water leak problem and the warning lighting I was getting saying low oil pressure stop car check manual, so it definitely needed replaced and fixed this main issue but it hasn’t stopped my water leak completely I’m seeing water drip from just behind it but I can’t see where it’s coming from. It seems to be a pipe that’s hard to get to or see to diagnose where the leak is coming from or which pipe it is. Any ideas?
There are a couple other coolant fittings, hoses and pipes in at area. Unfortunately it sounds like you will have to pin point the leak know what needs to be replaced. There is a hose that attaches to the filter/ cooler housing. Make sure the hose is good and that the clamp it secured. That probably the best starting point.
Hi , I just got the mysterious coolant leak, in my 2012 jetta tdi! is the oil cooler housing similar because they have the right side up oil filter housing and no intercooler in the way . I’ll probably pull a vacuum on the system and see if it’s leaking there. Thanks for the video!
I believe it’s the same exact part. The link in the description is for the part from Amazon, you should be able to confirm fitment on Amazon. If you don’t have to deal with the intercooler it should be a much easier job.
No, but I would recommend an oil change after you install the new housing. There could be coolant in the oil system and will now have a new oil filter anyway.
Im trying to diagnose my gfs 13 passat tdi and am 80% sure this is it so thanks for making this video its hard to tell for sure but coolant is running down the oil pan and a significant rate and this part seems to be the highest. Would this also cause the heat to stop working or is it more likely to be a heater core as well as this?
80% sure is about as good as it gets. When you have the old one removed you can look at it and then you'll see the issue and be 100% sure. It sounds kind of funny but that's how it goes for me every time. No heat especially starting out on the passenger side is definitely the heater core. I have replaced about a half dozen of them on these cars. it's a little annoying to get to, but not a terrible job.
Seems this is a common issue. My 2,0 TDI Alhambra was leaking coolant, when put under load this was the part identified as bad. That same section was all destroyed. Like in that one the plastic was also missing.
Quick question sir! With this issue specifically, is any coolant leaking into the oil line? I may have this issue and I need to be able to drive around until this is fixable
I just replaced another one today, lol I have not ever had cross contamination. The area that fails just leaks coolant externally down the side of the engine block. You should be fine to drive it a little longer, just watch the coolant level.
My 2009 audi a3 sline 2.0 tdi automatic, loses its coolant, no wet spots under the car, and no smoke from behind. Most of the people say its engine head being made from bad material and it leaks in engine trough microscopic holes or something. Do you think this may be the problem?
I would definitely take a look at the oil filter housing. Sometimes they will leave a puddle under the car but usually they will leak when you are driving, and the system is under the most pressure. There may even be some coolant puddling up on top of the underbelly shield that never shows up where you park. I've seen enough of these fail that I would definitely investigate it.
Same issue here. Exhaust smells sweet although the oil seems normal. Check for radiator / pipework leaks, thermostat housing, heater core, oil cooler, egr cooler, then head gasket (if there was performance upgrade the head may have lifted...)
Sorry, I don’t have a video on replacing it. The leak can vary. Some days it won’t leak at all and other days it will. It never pours out, but it can be a pretty steady drip. You will never get a good view of the exact spot it’s leaking from so if it leaking from that area, that’s probably it. The good news it that when you take the old one out you will confirm immediately that it’s the problem by seeing the failure point.
We don't have the T5 here in the US but from what I can tell it looks like the same part. Very likely problem on the T5 as well. If it turns out you are having the same issue on a T5 please report back and I'll add that to the title and description of this video.
I'd also love feedback from anyone else. I buy 1-2 of these every month. The last one I installed was 4 days ago. I have not yet had anyone come back for a failed one. I wish there was an improved all metal option but I haven't found one yet. That's why I linked an inexpensive one that I have had a 100% success rate with.
@bennieaust well if you've bought several with no issues then I'll roll the dice and buy it. Same part is $160 at Autozone is the only reason I was skeptical of this one for $28ish.
That alone equates to one of the worse automobile designs in the world; and i AM SURE it was done on purpose!!!! of course it was, they do KNOW better than that, they've been making cars for a good month and a half... if you're not already married to such VWs, avoid them

Legend ! Save me a lot of diagnosing. There is a coolant right under the oil filter housing of my 2011 Sharan. So this makes a lot of sense. Thank you
You’re welcome!!
Thankyou for sharing this info.! Saved my Christmas! oil cooler replaced with the Alu unit, car back on the road in a few days..
@NateHorne-p3s great to hear! Merry Christmas!!
How long does it take to replace ??
A couple hours. It's a pain.
Yep. Just saw it today, while replacing my serpentine belt....
Great video. Thanks.
You’re welcome! Sorry to hear it’s leaking but catching it early helps keep you off the side of the road. Best of luck with the replacment.
Thank you, after watching your video I was able to diagnose this correctly on my 2012 tdi - Thanks!

It's amazing how they almost all fail exactly the same.
Another question for you sir- does the Amazon link include gaskets and the bolts? Thanks!

Mine 2015 TDI just did this between the oil cooler and the housing.
