Hey.

So about 3 weeks ago, I bought a 2017 2.0 diesel 4x4.

If i had the heating on, I lost coolant, but no heating, no loss. It went back to the garage I bought it from and they said there was a loose hose on a recently replaced matrix.

Yesterday, had heating on etc and checked it while the engine was slightly warm (about 4 hours later) and was fine, went out this morning and lower than it was last night. Seems to have lost it while parked. Anyone else had similar or an idea what it may be?

Ta 🙂

Hello everyone!

I own a Kodiaq 2023 1.5 TSI, bought new. After about 22000km, the yellow low coolant light came on, and at about 26000, another warning, the one for low engine oil level. I visited the service center to check and fix the problems. For the oil, their answer was that it is normal to consume oil, and for the loss of coolant, their answer was, there are no losses, everything is ok, without further explanation.

Regards.

Are you seriously saying that the oil in your engine has not been checked for 26000 Km?

Yes it is normal for an ICE engine to consume a small amount of lubricating oil - but, at that distance, I'd have thought the oil would have been due for a change in any case!

For your ghost coolant level warning, did you visually check the coolant level yourself before taking it to the service centre? Was the level below the minimum level marked on the side of the expansion tank?

Unfortunately I'm not kidding. When the yellow light came on, I was on vacation in Europe, the fluid was well below the minimum level. It was necessary to top up with approximately 700ml

Do not know about Kodiaq, but Alfa 156 2 litre petrol engine had an oil consumption 1 liter per 10 000 km. Stated in manual.

Has the coolant level fallen since you topped up 700ml?

Strongly advise you to monitor both oil and coolant levels more frequently - the oil usage is probably normal given the distance travelled, but the coolant really needs to be kept a very close eye on for some time until you can confirm there is no leakage.

Why is there so long between oil services - do you plan one soon?

It is a big mistake to simply rely on warning lights instead of doing regular engine checks.

Now I constantly monitor the oil and water levels, but after the service visit the car sat in the garage more than it was driven.

700 ml of engine oil into a 1.5 TSI ACT that had a Low Engine Oil warning means the oil level is probably low.

Best check it as it should be checked. At normal Operating Temperature, so once up to an indicated 90*oC or so, parked on the flat, engine off and after a few minutes. A few is 4 or 5 minutes, like about how long it takes to fill up the fuel tank. A good time to check, even if you need to move away from the fuel pump. Old Skool.

When you know where the correct level is checked that way, then check cold and you know where it is before ever starting a trip, if you look.

Coolant does not always need to be filled to MAX.

There is MIN & MAX, if they wanted there could be a FILL TO THIS LEVEL Line.

Coolant sets it,s own level. Going to MIN & and there is an issue.

Low annual distances travelled (or regular short trips) make regular oil servicing even more important - you should consider planning your servicing on an annual basis.

From the post, it reads as if it was the coolant that had the 700ml top up.

anyway, Skoda admits that all their engines consume oil, which is normal. But for the low water level in the cooling system, it has no explanation

It's not my first car, but out of over 7 cars, it's the first car that consumes both oil and coolant.l ,and I am the first owner

Re Kodiaq, or any VW Group Engine, 3,4,5,6,8,10 or 12 cylinder , 44kW up , petrol or diesel there thing is to say May use ass much as 0.5 litres oil / 1,000 km (621 miles.) so 1 litre in 1,242, depending on use, more maybe in first 5,000 km.

Tosh, but they say it.

Alfa Romeo were amazing if just 1 litre in 10,000 km. But then some cars were possibly rusting away before they needed oil.

@Tipitip VW covers their back end by saying their engines may use oil.

They never got away with the crappy ones that were extreme oil users. Well not in some world regions, they fought it out in Europe. People had to fight individually to get an Engine Fit for Purpose.

It should not use (lose) coolant at all - as I suggested earlier, monitor the coolant level regularly from now on to check if it is losing it. Take it back to garage if it is.

I constantly check the coolant level and if it drops again, I bring the car back to the service. Otherwise, there are no signs of leaks anywhere, white slime on the oil dipstick, etc.

thank you all for the advice and suggestions

Note, it is possible that when the coolant level falls to a point where the expansion bottle is completely empty, air pockets can become trapped in the coolant passages of the engine - if this is the case, it may take some time for the trapped air to be purged from the system, the coolant level will drop as this air gets purged, mimicking a leak.

Hello everyone.

In my case, the problem persists. Last year in august I performed the 30,000km service, where I reported low oil and coolant levels. Today, after 1 year and 12,500 km, the coolant and oil levels have dropped again. In the first attached picture, the coolant level appears after last year's service, and in the next picture, it is today's level. In the last picture, the oil level.

There are no leaks, stains, the oil is clean, etc. I am waiting for the service unit's response, with the date and time of the appointment to take the car for checks. I will come back with details after the service visit.

Regards

Unable to read dipstick as image is out of focus, but considering 1 year and more than 12,000 Km, I wouldn't consider that you have a problem.

Was the oil level above minimum level? If so, I'd guess only approx. 0.5 litre used.

Do you check oil level between services?

Hello everyone!

This is the response received from the service unit

"Oil consumption in the engine is a normal thing the manufacturer states that the allowable amount of burned oil is 1 liter per 1000 km. As for the coolant, it all depends on the travel conditions, the length of the trips, and the driving style. If we are covering a longer distance by car, it is known that the coolant temperature will remain high all the time, which can cause it to evaporate over time, and this is a normal way of using the fluid. If its temperature rises above the permissible level, then it would be necessary to schedule a service appointment. Therefore, I believe that everything is fine with the car because these are operational fluids, and they will wear out over time."

Absolute tosh for the claim regarding coolant loss!

The engine cooling is a closed (sealed) system - provided the system is free of leaks and is not subjected to overheating or excess pressure, coolant loss should be close to zero.

Apart from a scheduled coolant change, I have never had to add coolant to either of our two Skodas.

If in the case of oil consumption there is a specification from the manufacturer regarding consumption, in the case of coolant, the manufacturer does not specify anything. Moreover, the cooling circuit is a hermetic and sealed circuit, with no possibility of evaporation. Both theoretically and factually, these losses are, from my point of view, a technical problem that must be investigated and remedied. Following the response received, I requested a service appointment, for investigations with the mention for service, that if they do not discover the problem, I will schedule the car in another service unit, from another locality/country, to ask for another opinion.

Yesterday, the car had a service appointment regarding coolant leaks. After about an hour, the service unit's response was "everything is ok, there are no leaks". Honestly, it's the only car I own that leaks coolant, and for which the service says everything is ok, even though the manufacturer of the brand doesn't specify anything officially.

It would be more accurate to say that they could not locate the coolant leak!
