Coolant warning

[Scratchyratface]

I had a coolant leak in my TT just last week, turned out the Thermostat had a leak (the water pump had already been replaced under warranty). Thermostat & labour cost me $2000, unfortunately out of warranty

Just before my 2 year/30,000km service I've got the coolant light come up. The water level was just under the line in the reservoir. I thought the dealer would just top it up and send me back home but no, they did a pressure test without asking and found a leak. They replaced the thermostat housing. It's all good now.

That's good to know. Thanks.

My 2016 Passat B8 132 tsi has coolant low warning light come on at 27000 klms. Checked reservoir and it was indeed below minimum. Took to dealer. Was pressure tested no fault found .topped up and issue attributed to air lock from factory. 10000 klms later at minimum level again this time tested again and leak from thermostat housing detected. Housing replaced and VW also replaced water pump as precaution . 10000 klms later again at minimum level. Pressure tested again no fault found and issue attributed to possible air lock when water pump was replaced. Topped up. 10000 klms later again at minimum this time the most ridiculous excuse given and I have this stated on invoice from VW dealership and was repeated from VW Australia. “ coolant consumption up to 500 ml per 1000 klms is within specification. This means your vehicle could consume 7.5 litres of coolant within a service interval and VW would consider that vehicle to be operating within specification. Would you consider such a vehicle fit for purpose? I dont

That's good to know. Thanks.

Crock of ****, is my thought.

Happened on mine as well. Was up in the hills on the Qld/NSW border on a Sunday after driving from sea level to 1000m ASL.

Short of anything else I pulled over and topped it up with water at the time. No further issues since.

Happened again the other day, changed the dash display to watch oil temps and could see them rising rapidly...evidence of a leak around the water pump area.

Luckily a dealer was nearby and I dropped in. Next to nothing left in the coolant reservoir, when the tech opened the reservoir up the system spewed out a heap of fluid all over the place. His explanation was a huge airlock, said it will need full flush and refill, topped up with water only as they didn't have access to the parts department for the G13 required. My old GTI did exactly the same thing as this when the water pump let go, so my guess is the water pump has shat itself.

Driving the wifes Golf around in the meantime, Tiguan goes in this week to be looked at...

Sigh, mine has been topped up 3x times by the service centre too

Once when I noticed the issue, 2nd time at it's 15k service and 3rd time when I went into get the bearing/grease fault addressed.

nek minnit blow pump, and lift a head.

It’s nothing unusual and once it’s out of warranty they happily report it and charge for the repair.
Many drivers will not even know that there was a leak and it’s been topped up a few times or think that it’s normal to add coolant during the year.
It isn’t normal, the cooling system is closed to the outside air most of the time and there shouldn’t be any top ups needed. The amount of water that evaporates is negligible and the level should always stay close to the max. If the alarm comes on, there’s a leak.

But thank you for the 5 year warranty, going to sell it at the 4.5 year mark and buy another Tiguan (MK3 or 4?) and rinse/repeat lol.

I do like the car, all the creature comforts, but it sure stands up to its name of being unreliable!

Unreliable?
Did it break down?
Did it leave you stranded somewhere?

Assuming all stories are being conveyed truthfully (and there’s no point/evidence assuming otherwise) then I think it is a reliability issue- for those users.

My car has had the sunroof lights replaced, AID replaced, 9.2” screen replaced, drivers seat replaced- all in les than 10000kms.

My gearbox is a bit crap (I suspect either logic, or solenoid issue) with its 2nd/3rd change. It won’t always respond to the paddles and holds the change in auto modes far too late. It also often slips/slurs the change- under varying throttle/incline/decline situations.

The car hasn’t broken down, but they are faults and failures.
