SQ5 Tdi coolant temp

[jmfjohn]

Hello world,

This is my very first post as I bought a 2015 SQ5 Tdi today. When I picked up the car it was warmed up. I then proceeded to drive home, about 2.5 hours drive, out of which the first 30 minutes were in a 80km/h limit area going up and down some mild hills.

At some point during these 30 min I noticed that the coolant temp was about 75 degrees, instead of 90...which seemed odd, but thought maybe the car wasn't really warmed up when i picked it up. I continued to watch the gauge for the next minutes and it went up to almost 90, then back down, then back up a few times. Finally upon going up a hill it reached 90 and stayed there for the remainder of the 80 limit portion of the trip. Once I reached the highway and sped up to 120km/h it stayed on 90 until I got home.

Did anyone have this happen before? My first thought would be faulty thermostat (or sender) but maybe it's normal?

Cheers!

Hey Adrian welcome to the forum :) 

You'll find the members on here are a friendly and helpful bunch :) 

In my opinion this is normal. I appreciate my a6 is a lot older than your Audi but I do similar driving for work (country roads between 50-80mph) and my temp gauge fluctuates. It will stay at 90 degrees if I'm doing continued motorway driving. I'd say monitor it but In my opinion and experience it's normal :) 

By experience I've worked in a Volkswagen service department.

If it goes out of the norm zone then you've deffo got an issue! 

Hope IV helped :)

Hi Steve,

Wow, that was a fast answer! Off the top of my head I'd say you started typing it as soon as I posted my question :D

Thanks for the feedback. It's interesting that your gauge fluctuates too. It's my first Audi, having owned Skoda, VW and Ford before and all their gauges were rock solid. When I DID have a fluctuating gauge it was actually the thermostat. 

I'll keep it under observation, the car still has about 6 months and 15.000km warranty, so I could have it replaced for free probably if it's gone.

Cheers,

Adrian

I'm nearly always on.here lol! 

And I have to say with mine it's not an age thing as my a6 has been owned by the family from new and it's always been the same. 

It is interesting how gauges differ from.each manufacturer and you'd be right in thinking a thermostat would be an obvious culprit. However is suspect if that were the case the car would not be hearing up to temperature at all. That was my case on my other car which is an old Ford escort. 

For peace of mind it can't hurt it being plugged in for diagnostics at Audi as it's under warranty. But for me I'd say everything is normal :) 

Keep us posted on how you get on :) 

Oh and by the way we have a topic which shows Audi's in all parts of the world. Please feel free to show us some pics of you SQ5 in lovely Switzerland! ;) Here's the link...
