Hello All
First post in the mk5 forum. I usually lurk in the mk2 section :smiley:
My wife bought a 2005 GTI in September. I am surprised how long it takes the engine to get up to operating temperature. This morning when it was 0 degrees outside, it only reached 70oC on the temp gauge after a 12 mile/23 minute commute to work.
I immediately thought the thermostat was stuck open but once it actually gets to 90oC it doesn't move from there so I'm not so sure.
In contrast, my previous mk2 Golf and Lupo GTI, under the same conditions would be fully warm in less than half the time.
I have done a search and from the one relevant post I could find, it would appear to be the norm. Does anybody else have this 'problem'? Any suggestions appreciated.
-
I find mine very slow to warm up in cold weather too.
-
Mine is hardly ever that slow. I usually hajavascript:void(0);ve the car running for about 5 mins before I drive it, then its up to temp less than 2 miles up the road
-
Thanks for the replies.
Jeynesey, actually I did that last night. Started it up and it was probably 5 mins before I cleared all the frost, pretty sure that 2 miles into the journey the temp needle hadn't moved off the starting point!

Weird. Even more so that I am usually leaving the house at 5.45 :undecided:

Could be one of 2 possible problems that I've seen before.... Could be a slow temp sensor or check your coolant anti-freeze. VW ant-freeze fluid has a special mix that brings the coolant up to optimum temperature without allowing it to boil.
A similar thing happened to a friends car, had non original anti-freeze and once the coolant was replaced the problem disappeared.
Just a couple of suggestions but the anti-freeze used really can make a difference.

Now, I have this problem with my 2005 gti but even worse with a diesel Tiguan. The VW heater electronic controls are not very sophisticated. Many other types of car have heaters that automatically only start blowing air after the engine coolant has reached a certain temperature. This has 2 purposes.......1) You don't get freezing air blown over your feet and face and 2) The engine warms up a lot quicker!
So to overcome this problem...........Turn the climate control OFF and only select AUTO when you see that the engine temperature has reached a reasonable level. This is where heated seats really come into their own - if you are lucky enough to have them!
-
yes mk5 slow to heat , think mk3 were the quickest to heat up , heated seats are great on cold mornings especially if u have leather
-
MK5 1.9tdi 2005. (No Aux. Heater) Original Coolant (Antifreeze increases the boiling point, not sure if VW's is special)
Start engine with blower & temp. on full, (ECON Light Not Lite, I never use it) Rear Window Heater ON.
While scraping ice off windows ice begins to melt.
Heater working as I leave the drive & 2 miles on temp. gauge still at bottom, after 5 miles shows 90 degrees. Warm as toast.
-
my mk5 is the same in this very cold weather gauge takes a bit of time to hit centre...
love my heated leather seats too :tongue:
-
My MKV GTI was the same, last winter when the temperatures were -5 and below the car never warmed up on my journey to work, about 30 miles.
I logged it in VCDS and it seemed to get to 70 quickly enough, then the thermostat seemed to open and the temperature went down again before eventually crawling back up to 90.
-
Thanks for all the replies. I will check the coolant and tell the Missus to turn off the heating. She'll probably ignore me on the latter point :grin:
From the responses, it would appear to be the norm although I can't believe it is 'right'. Given that emissions and green issues are always hot topics, I find it unbelievable that a modern car like the mk5 can take so long to warm up and presumably belches out lots more nasty stuff until it has reached operating temperature! :undecided:
Can't seem to find much stuff about it on the Internet though. In fact, can't even find somebody who sells the thermostat assuming it has one.
-
My pirrelli is normally warm (90) on the gauge after 3 miles. In the cold it might be 5 but 30! That's mental.
There is something wrong there! I don't think it is a slow car to warm up at all.
-
Warmup time also very dependant on driving conditions - speed and road inclination.
-
i know loads people with mk 5 , there all the same , mk 4 , were the same as well , why i dont know , maybe someone from vw might have the answer ,
-
Mine seems to warm up within 5 minutes of driving. To be honest for the first 5 mins i plod along on purpose to let it warm up.
If it was 30 minutes i don't think i'd have the patience :tongue:. Maybe it's a faulty temp sensor ?
-
Hmmmm this is just getting confusing now. Maybe it only affects the early GTI's? Correct me if I'm wrong but I believe the Pirelli edition is much newer?
Bet somebody now replies with with an early GTI that warms up in 5 mins too!
-
Can i throw in that i have a 2.0 tdi Touran sport with aux heater and i to am still freezing after 30 mins :sad: i asked a dealer to check aux out when it had a new turbo fitted about 8 months ago and was told no faults showing? i have seen people saying about checking the fuses, any idea what number fuse?

Ditto :smiley:

Right don't know if you guy's have auxilery heaters like my touran but had it checked today, and it turns out the electric pump that feeds coolant to the aux heater is dead! the aux heater fires up an cuts out after a few seconds as the temp switch in aux smashes past 100 degrees :sad: so new part £111.98 and front bumper off to fit :cry:
-
I drive a 2005 GTI and I have always found it warms up pretty quickly, 10mins maximum, obviously depends on what speed you are driving at, and also outside temperature but half an hour seems like something may be faulty.
-
Basic engine thermostat perhaps? The brass thing that sits in the coolant, it might be stuck open. Cars take ages to heat up when that has failed. They are also really cheap and easy to fit.
-
Well the commute consists of 30 mph for about 5 mins until I get to the motorway and then I'm on that for about 15 mins at 70 mph. I would've thought that would be quite favourable for warming up.
I suppose the thermostat could be stuck open but in my experience, when this happens the car takes ages to warm up and may even hit normal temperatures when going slowly but as soon as you go faster, the air flow brings the temperature down. That isn't the case here. Once it gets to 90 oC, it doesn't budge whether you're stuck in traffic or on the motorway.
Might give the garage a call. Wish I had Phil1980's car!
-
Depends on the drive aswell. In the mornings I pretty much drive out my road into traffic and it's all very stop start and can take ages. I've driven to the office on a weekend before with no traffic and warmed much faster than usual. I think for this reason mine also takes quite some time to warm up.
Nick, the only reason yours warms up so fast is because you drive it everywhere like you stole it :D
-
My 05 GTI used to take ages to warm up in this weather,after a 7 mile drive on an A road to work it was still only around a 1/4 on the temp gauge.
Changed to an 08 Edition 30 last week & what a difference,same journey to work & gauge is on the correct temp & hot air through the vents (& seats) :grin:.
I think the thermostat was faulty & for what they cost if your car is taking ages to get warm it would be worth changing.
