MY12 TDI Wagon Losing Coolant

[Amalgam]

Hi All,

Our MY12 125TDI wagon is losing coolant. It has lost the volume between Max and Min mark in the overflow bottle when cold. This has been during 15000 to 26000kms. There is no obvious loss into the engine bay. There was some minor loss at the 15000km service, which was topped up by the dealer.

Should I be worried?? Can it wait until the 30000km service, if I keep an eye on it or should I bring it back to the dealer ASAP

BTW the engine has consumed 600ml in 8000km. I assume that this is OK.

Thanks in advance.

Book it in and arrange to have it looked at.

Better to be safe than sorry.

As Umai Naa!! said get it looked at. But, keep the record of it. The cooling system is a closed one and there should be no fluid loss due to evaporation like in many other cars. If, the fluid level is going down repeatedly there is a leak somewhere.

Your oil consumption is okay.

If you are losing 3L in 1000km there must be a noticeable leak and wet patch under the car. If it is lost via the engine eg faulty head gasket, there should be a noticeable deterioration in performance and water in the oil.

How many kilometres has your car travelled and when did you first notice this loss??

Good luck on Monday and please keep us posted.

There is generally a small patch of water under the car, I can't notice any water in the oil. I first noticed last Monday went the warning light came on. I have traveled 74000km.

Let's hope it's an easy fix.

Hi Ganue,

How did it go at the dealers?? The repairs should still be under warranty I am hoping

Hi amalgam

Turns out the water pump had an internal leak.

So new water pump was needed. The timing belt was also contaminated by coolant so it was swapped out as well. It's all covered under warranty.

All good in the end

That's a good result and you don't need to worry about the timing belt at least for the next 105,000km.
