The coolant loss was the most serious issue, but a deeper inspection while diagnosing the coolant issue revealed a number of other problems. The mechanic was pretty blunt saying I had been sold a lemon and he was right. Dealer took it back and gave me a full refund considering the state of it. I'm near closing on a MY19 Superb 2.0 TDI 150 DSG SEL just like yours actually. Let's hope I have better luck this time.

Any news since this post? I've had similar coolant vanishing problems that 3 different garages couldn't diagnose. Also on a 2.0 TDI 150. In the end, I decided to return the car to the dealer I bought it from, but still very invested in understanding what might cause these issues. Hopefully you resolved yours.

I recently did a trip down to Italy in a 2.0 TDI SE Business. Was a very comfortable journey cruising at 130 km/h through France, Switzerland, and Italy. Fuel economy was excellent around 60 mpg. If you check my post history, I ended up with a lemon that did give me some problems once I arrived in Italy, but I think that was bad luck. I'm planning to buy another Superb because I still love what it offers.

Nope, just the best Italian grappa I could find. The original antifreeze!

Tough break mate. Have you taken it for inspection anywhere? Mine is also 2016. Perhaps a bad year for Superbs and coolant...

Yeah I'm 0 for 3 on garages finding the leak. Pretty disappointing. When this is all over, I'm still tempted to get another Superb. I suspect I was very unlucky with this one. The space and comfort the Superb offers is perfect for me and my family. And I've been driving Toyotas since I first started driving 20 years ago. Absolutely reliable but have to say I really wanted a change. Honda seems like more of the same! Thank you for the luck. I'll need it.

Well I heard back from the garage. They did the compression test and were able to rule out a blown head gasket. Bad news is they couldn't find where the leak is happening, found all kinds of things loose, poorly patched up starter, and a oil leak to top it off. Seems like lots of poorly done work had been done to the car before I received it. I paid for a pre-purchase inspection and they said the car was in great shape. What a waste. This garage was even more pessimistic than the garages in Italy about finding the source of the leak. It could be the water pump, EGR valve, or Lord knows what. Talking about many hours of work to find the coolant leak. He was honest saying I should send the car back to the dealer and get my money back considering the overall state of the engine. Tough to hear that, but he might be right. Now I need to figure out my rights. It's been about 60 days since I purchased the car which should normally be fine, but wouldn't be surprised if they give me grief for driving 2500 miles round trip down to Italy and back.

@Ootohere Forgot to mention it's on a little over 100k miles.

It's a 2.0 TDI. Unfortunately not a VW specialist. The local VW specialist couldn't see the car for weeks.

I managed to get the car all the way from Italy to Cheshire successfully. I went through 5 litres of pre-mixed G13 to get it here. It was a fairly smooth journey all things considered. I checked the level before every drive and topped up accordingly. The low coolant warning only came on twice while driving which isn't too bad. The first time we pulled over in a tiny French village on the outskirts of Epernay. It was lunch time so plan was to eat while the engine cooled before topping up. Alas there was nothing to eat around the area except a 24/7 pizza vending machine! It did the job. I felt a great sense of relief arriving in Dover knowing my warranty would be valid again and that I could speak English in case of any serious problems. As for the state of the car, it's begun having issues starting on a cold start. I need to try the ignition 1-2 times where it struggles and fails, wait a few minutes, and then it'll start finally after a bit more struggling. I took it to a garage Friday morning to check both the start issue and coolant loss. They only had it for a couple hours, but they seem to think it could be a blown head gasket, not the pump. They also think the start issues are related due to low compression. I had ruled out blown head gasket based on what the two garages in Italy said. The same garage will look at it again tomorrow to give it a proper diagnosis. We'll see what they say. Shame I've had so much trouble so far. I absolutely love the car and can't wait to resolve these issues to properly enjoy it.

You can certainly do that. This video explains how it works: I haven't tested it myself, but I'll surely give it a go once I get my car back from the garage.

Fortunately I have the adaptive cruise control. Absolute treat to drive with on the motorway for long journeys. Previously I always had the old cruise control which looking back feels insanely dangerous as you pointed out. Thank you. I managed to find a place to look at the car tomorrow thanks to a friend of a friend. I'll update the thread if they find anything worth reporting.

Very helpful thank you. I'll keep these in mind. I mostly keep it in Eco mode on long drives anyway to save on diesel. I haven't tested the manual/semi-auto mode of my DSG so I'll give that a go to keep the revs down. We were also already planning to do our drives in the morning. We've scheduled overnight stays in various places that are only ~4 hours apart. If we set off at 7 and arrive before lunch, we'll hopefully avoid being on the road at the hottest times of the day. I checked the 2016 Superb owner's manual and this is all they include. Mental they wouldn't include all the information yours has.

Just ordered three 1L bottles. The 5L was much cheaper per litre of course, but the car will be rather full for the drive back. Easier to pack a few small bottles in little nooks than a single big one. I figure if I get down to one bottle, I'll track down more ASAP. I'll take it easy on her. Fortunately won't be going through Germany so I won't be tempted to do a max speed check on the autobahn. How hot do you think is too hot for the oil temp before I need to cool things down?

Just checked that: G13. That all makes sense. Thank you. Can't wait to get the leak sorted and the tank filled with only proper coolant. Let's pray that I get the car back to England without an unscheduled stop along a French motorway.
