Thank you so much for the video! Question: Would the check engine light come on for this problem, or would only the coolant sensor? We bought a 2014 Q7 TDI, a private dealer. I wonder if it's easier than tearing apart the engine
Are there any other service jobs you'd recommend doing at the same time as this major bit of work? Like any other things likely to fail or need cleaning for the mileage. Like the egr and pipes leading to it or the water pump.for example . Cheers .
Thanks Dean for sharing your tips. I’m from Saudi Arabia, my car bought a brand new Q7 2018 petrol V6. I have the same issue as you described. I took it to the garage and they said on the spot water pump need to be replaced! Do you think the stop valve also applied to my car type? Keep up posting your great tips 👍
Explained very nice, it seems i have the same problem on my audi q5 3.0 tfsi v6 2014, the coolant leaks down in the corner on the right side and a bit in the middle, i brought it to the garage and they just changed the water pump, but it still leaked after that
@@legendaryprivate the tfsi water pumps are a very common problem for leaking. The engine setup is different to the TDIs. I've not seen anything leak on a TFSI except the water pump.

No. Your car does not have this part. Best thing to do on yours is to take all the parts out inside the V and replace all gaskets and coolant junctions
Great vid. Ive just replaced the waterpump on a 3ltr Q7 and it is still leaking! Looks a lot of fun stripping down to access it (said with trepidation and a flickering eyelid) How much do i quote, do i actually want the job or should i close my garage and get a job in a supermarket now minumum wage is £11.50ph for an easy life and be done with it? Its all to be considered lol. But yea, ive got one and your vid has saved me a lot of pondering of the unknown and blind speculation to the road ahead. We are in Bolton so if i sleep on it and then decide i dont want the job i will refer to you guys.
I am doin same job but it definitely looks like the thermostat is leaking aswell coolant staining everywhere and you don't change oil cooler gasket while you in there?
I have the same problem on my 2017 Audi A7 3.0TDI. Thank you for posting this video. I have been topping my coolant up for 2 years now and it hasn’t caused me a problem. The coolant leaks extremely slowly - I only need to top up the coolant tank once every 2 months. Can I continue to just top up my coolant and live with the slow leak? Or do I need to get this fixed? Thank you.
I highly doubt this my friend i had an old gearbox control unit on my 2016 A7 that in the end was giving me faults and i had to replace it with new update one 😂 total cost £2500 lucky I bought insurance with the car. But i have similar issues and i can see coolatnt leak at the bottom. Anyone knows how much this cost to replace ?
Hey guys. I have a 2020 A6 2.0 tdi with a coolant leak cannot find where it is can’t see anything at the front of the engine. Losing about 500ml every 1500miles. Garage has no clue either!!
Thanks for the video. I am having coolant leak on my 2009 Q7 4.2 fsi, can't seem to tell where the fault is. Any ideas if it is same problem with this model or what the common source is for the 09?
I had the light come on for coolant and refilled it. The light went away but I did notice a small leak on under the engine on the left side.. could this be the issue for my vehicle too I have an 17 Q7 premium 2.0
Hi my q7 3ltr 2007 having water losing macanic says its head problem the goes out with pressure through over flow pipe but no one is trieng to look at it properly it does not over heat but wen go on motorway temperature needle goes down some time
Im having a similar issue with my 2013 q7 supercharger. Changed upper and lower radiator hoses and its still leaking. Can't really find the leak because its hitting the belt and throwing coolant everywhere. Can i be going through the same issue?
I am glad to come across your channel. Valuable information. I have the same issue. Could you please provide me with your location and contact info? I have the same issue for Q7. Would love to hearing back from you❤
Got a small leak on a A6 Allroad -16 3.0 TDI 218 ps, could this be the same problem? Refilled coolant 2 months ago and lost about half of the coolant from the reservoir
I had exactly this problem with my A6 Allroad. Luckily bought approved used from Audi so got it covered under extended warranty. However the service team at the local Audi service did something wrong and managed to detonate three of the six pistons almost blowing the head completely off. I wondered why the quick job was taking a little longer than expected. Eventually got the car back four months later but unfortunately lost all confidence in her so chopped it in for a 2016 Q7. Now experiencing exactly the same issue. Got a low coolant warning this morning and had to top up nearly a litre of coolant.
I have an Audi 2008 Q7 3.6 and no one can find the leak could this issue be the same for my auto. I am in the USA however I love Manchester! Futbol/Soccer!
AD I have a question Im from California I recently bought a used 2008 Touareg 4.2 fsi 172k from a private partty site unseen in Ohio for really cheap price the car seems to be in at least a 8/9 condition mechanically supposedly been sitting for 2yrs . Required a jump to start but engine ran smooth after test drive it was taken on 70 miles trek where it was discovered a high speed vibration which I believe could be the drive shaft ..the concerning issue is the above 70 the tempeture rose excessively and gave warning indicator once brought speed back down to 55/60 tempeture came back down to normal operating I used a service to obtain vehicle for me and I know they did not check any fluids at all at 55/60 the ride was uneventful..my question in your experience would this point more to water pump or thermostat ..I assuming it could possibly be low in fluids but if that be the case it will probably have a higher than normal operating temp once it was raised above normal..what do you think
Hi. We never got the touareg 4.2 in the UK. We did however, get the Q7 4.2, so I assume they are similar. I've not seen that problem with the 4.2. You're problem could be a few things. I would be checking all your coolant pipes are getting hot. If you have a cold one then your problem is on that circuit. If you can't find a cold pipe, you need to start changing the WP and thermostat, and go from there.
Well, this is common for the previous 2gen diesels as well. But in the video it was not showed clearly the valley of the cylinder head. If this EGR cooler regulator leaks than the valley should be full of coolant first. From the video it was not possible to judge whether it is the case or not. It seems to be impossible to diagnose the leaking such a bad way by the previous shop, not checking the walley for coolant first.
This engine does not have the same EGR cooler problems as the previous generations. The setup in the valley of the engine is totally different to the older engines. I have now done about 10 of these end EVERY time, it has been this valve. So I can pretty much guarantee that if you have this leak on this generation of engine, the valve is the issue.
Hey. Thanks for the video. I have a leaking valve and Audi dealer is saying around 5 hours labour (€550 to repair) Is that about right or are they having me on?
Hey! Thanks for the video. I have a leaking valve, Audi dealer is saying around 5 hours labour (€550 to repair) is that about right or are they having me on?
Hi. I've not yet seen this problem on an A4. The is a similar valve in the A4 engine but I don't think it's quite the same design. It's probably best to change the valve and all the other seals while it's all stripped out to be sure.
Hi - I have a similar problem. 4 years ago my local Audi dealer replaced the shut off valve on my 2015 Q7 4M and yet again it's now losing coolant again. Same dealer has suggested it's either the shut off valve or the EGR - but the issue is they can't tell without taking stripping the engine. Estimated cost of £3k which might not solve the problem. Any thoughts? Also where are you based as there aren't any contact details on your profile?
Would this leak cause high pressure in the coolant tank when hot ? I am experiencing coolant coming out from the reservoir, changed the cap , still happens. So I am wondering if the car has a leak can cause this symptom , it’s a cduc engine
@@vorsprung would airlock in the coolant system cause the high pressure too ? I sometimes hear gouging noise after the engine is shut down . Thanks for the speedy response. By the way , ain’t the part you mentioned one of the coolant valves?
