Anyone got or had this problem on thier golf. The temperature gauge intermittently works. One minute its giving a good readout the next it dies and gives no readout. The car isnt over heating tho ? so dont think its the thermostat

Possibly a faulty dash mate, I see it a lot with TT's. Get someone with VAG-COM to test it.

sounds like you need a new temp sender unit

I had the same problem, new temperature sender, 25 Eur in Portugal.

I may be wrong but I thought this was also one of the early symptoms of water pump failure?

I would say it's probably the temperature sender.

They are a known failure, and cause various issues when they start playing up.

Usually in stock at dealers - about ?20

Temp Sender.

Mine did the same when i first got the car.

Takes all of about 5 mins to do yourself.Just change it in the morning when the engine is cold.

Had the same problem with my Bora, got the garage to fix the temp sender unit under warrenty. it also caused the car to cut out on the odd occasion just after start-up.

now it is fixed i have no problems

Great , how easy is it to replace ????

 

[Mo]

Its a 5 min job

 

[macdaddy]

gonna ring the stealer dealer on monday for a price on that part then as its really annoying that it doesnt work. Any one know if it will damage any thing if its not fixed ? I thinbk the fan still kicks in !

Got the same problem on mine, garage said I need a new sensor however it's been OK the past couple of weeks.

Anyone able to give more details on how to swap it out??

 

[macdaddy]

i'd like to know how to change it if its only a 5 min job

To replace coolant sender

1. Make sure your engine is stone cold. Its best to do this early in the morning.
2. Take cap of engine collant resovoir.
   
3. Take
   of the engine cover and on the right of the engine block you will see a
   chunky coolant hose that runs from the radiator towards the back end of
   the engine bay.
4. Towards the back of this hose you will see a plug with a wire
   running from it.Slip a small flat end screw driver into the top of the
   plug then pull up to release it from the coolant sender.
   
5. At
   the side of the sender where it plugs into the coolant hose is a
   plastic U shaped clip.Remove this clip that retains the sender and slowly rock the sender back and forth to ease
   it out. you should only lose a few drops of coolant.
   
6. Once the sender is removed check that the
   rubber 'o' ring is attached to it, if not take it out from where the
   sender came from..
7. Fit new sender and 'o' ring and refit clip.
8. Refit plug and engine cover.

Sounds easy to me ! Thanks i'll have a go

 

[macdaddy]

Well, temp sensor cost ?28 from dealers and it took 5-mins to put in. I will need to top up the coolant now tho, so any one who reads this make sure you have some to hand. Just need to test it now , will report back

 

[macdaddy]

Tested and works fine. Thanks for all your help

yes im aware this is hugggggeeely old but

ok i fitted mine today,

changes ive noticed are

the needle takes aloooooot longer (30min ish) to get to 90c than it usually does (5 - 10 mins)

is this a good or a bad thing?

no fluctuations (never had them before)

no changes in mpg (THATS WHAT I NEED!!!- AN INCREASE THAT IS[:S])
