Engine Overheating! No Coolant Leaks & Coolant Level OK - Volkswagen Audi 1.6 2.0 TDI 1.8T 2.0T

In this video I work on a 2015 Volkswagen Golf 2.0 TDI engine that was overheating with no coolant leaks, no fault codes stored and the coolant level was fine.
I show what the problem was and how to test and fix it.

I am on the 2nd cambelt on this type of engine, always done the water pump in the process. What people do not realize is are a lot of revisions on this water pump and was a time when a new revision was showing up every month or so... as i am writing this the latest is 04L121011N for that pump. People should know the system has another 2 electric pumps one cooling the intake and another auxiliary just behind the sump above driveshaft... ecu controlled.

There is also an option to revert back to the old style water pump with no shield covering the impeller, if interested in that option I would recommend searching for compatible options online or through a parts supplier.
As always thanks for watching 😀

I had this very same issue with my vehicle an vw golf gtd mk7 2013 with 93000 miles on the clock. The symptom's were that the vehicle would overheat after a short journey and therefore carry on overheating until I got the problem solved. It started one day when I was travelling to a destination some 10 miles or so from my residential home. The vehicle temperature caused the warning on the dash board for myself to pull over and stop. The coolant temperature was in excess of 120 degrees. It took a short time for temp to fall with the help of the engine fan switching on only for then to almost immediately do the same again after a restart. New gates timing belt and pump fitted at local garage eliminated the problem where the pump in this kit does not have the invertor fitted. I did get a fault code prior to this, not too sure whether it was related or not where the secondary water pump showed up as been locked. I replaced this with a new vw one thinking this was causing the overheating problem but the problem persisted. The fault code subsequently kept reappearing after a short while but then vanished once I got the kit fitted.

Great video once again Gerard all to common problem on vag vehicles.🚗🇮🇪👍👍

Good info mate. It's important to understand how things work so you can use the correct testing techniques. Well done!

[thomasschwarting]

Don't all water cooled engines have a thermostat? Usually thats the issue provided no water loss. Water pump definetly could be an issue. Electronics, just more things to go wrong.

[dashcamuk]

I've got this kind of intermittent behaviour now but my water pump was only changed 3 Years and about 20, 000 miles ago

[careygreen]

Do you have video on changing that charge air cooler on that engine

[fintan]

Looks like yet another design fault in a part that's meant to save fuel, but could end up costing you a new engine.

My B8 Passat 1.8t tsi has the issue, epc engine lights on, power down to 40%. Will see dealer tomorrow morning.

Good video. Just wondering if this system is as robust as the old fashioned water pump which has a long life, the one with the metal impeller.

I have twice had overheating issues - one with 'stop' warning light, in the last two months. Ambient air temp 16 and 19 degrees c, oil and coolant levels all good, second time when I had no warning light the water temp needle was showing approx 100 deg, oil temp 91-94, radiator fan was running and temp came back down in a few minutes. Heater works. So i suspect my shield is getting sticky. Oddly VW main dealer did the cam belt AND (suppossedely) water pump about 3 years/40k miles ago. I did see fault codes with Carista on the first occurance - sure it said something to do with heater matrix or AC though?

[sulimangesur]

From where its get the air pressure to activate that????

[TinasheDev]

It looks stuck because of the oxidation. Won't removing rust and lubricating solve this issue?

Hi Gerard, My Caddy 2014/15 2.0 TDI started to overheat all of a sudden, 200 000 Km on the clock .... I managed to get home controlling the temperature by running my Heater and its fan which worked for me.... I was 1 hour away from my house .... As a test every time I turned off the cabin heater the temp would start to climb rapidly again and if I turned on the heater again the temp went back to 90 Degrees where it normally is .... In your opinion do you think it is my water pump?

Hi, I am looking for some advice. I bought a 53 plate audi a3 2.0 tdi sports back 6 months ago and it had an undisclosed over heating problem.
I know it's a 53 plate but I like it and it's my second car.
When I first got it, it would over heat and drop it's coolant.
I have solved the coolant problem but it still tries to overheat.
I have spent 2 grand so far and the problem still persists.
I have had the timing belt and water pump, thermostat, coolant sensor and radiator replaced, probably forgot some stuff aswell.
It is getting better but still tries to over heat if am doing about 70 and tun the heaters down low.
Any advice would be welcome, thanks

[chrissmith]

Cheers for sharing Ger.
Just a quick questions, from memory, how many miles had the engine covered before this electro/mechanical w.pump failure?

Cheers Chris.

Just wondering mate basically me and my dad heading to a car show we was sat in traffic on idle for a little maybe half hour to an hour and the temps would get high and dump water out ?

[sebaerce]

From where coolant pump get pressure to switch?
