few days ago i left mt AGU 1.8t sitting for about 3 days.. as had no need to drive!... and when i went to start it the whole engine and car was shaking really badly for about a minute..when the temp went up it all stoped... and few days after that it never happened at all ... the car pulls fine runs fine no smoke no nothing it was like a one off shake! lol
now after about a 4 days the temp gauge has creeped to 100 and slowly very very slowly was dropin back to 90.. what could be causing this and i recenlty had it fully serviced by kwik fit and put in a induction kit the same day when i got home.. and car ran fine iwth it for about week until the bloody shake and now dis!
could the induction kit be given me probs?? or is it the MAF?? as i havnt touched the MAF pipe or sensor at all..
heres pic the induction anyone see anything wrong?? :undecided:

the car was still running and pulling fine even when the temp creeped to 100.. its never ever gone over 90.. dont know what it could be?? any one else had this sort problem?? :sad:
-
Water pump is knackered. Maybe the 'jumpiness' was the impellor detaching itself from mother pumpy.
-
whats the impellor?? water pump!! damn.. thats expensive job aint it :angry:
what cuased it to go tho it has just been serviced too
-
is it dangerous to drive??? also if it is the water pump woudnt it of affected the drive and the temp gauge would be of the clock woudnt it :undecided:
-
The impellor, or impeller (can't remember how it's spelt until my brain recieves alcohol free blood, a few hours should see that happen) is bacially what I could describe as the 'paddles' attached to spindle of the pump that actually 'swishes' the water around the system.
Not sure how much the job costs, but it appears to be a common fault with these golfs that have the plastic impeller. I'm waiting for mine to be done actually, so you're not alone.
We need a waterpump support group as there have been so many cases of pump failure. It's a traumatic time for Golfs.
-

Not necessarily. With impeller issues, you can sit at idle at the temp can sit at 90, drive it and it can go full scale deflection, then cool down again as the engine idles.
-
i got exams dis week coming and now i got no transport :angry:
just when i thought the golf was most reliable car in the galaxy :angry:
id have to pop over to garage tomorow then get some prices... im flat our broke too so wont see this hapning anytime soon ..
take it its not safe to drive then is it ?? :sad:
-
hmmmmm ill just use it for this week then and drive calmly :nerd:.. should be ok for a week its only 10 miles der n bak.
could it be anything else??? as i can see my fuel consumption has droped slightly too.
-
I wouldn't drive it, you'll risk damaging the engine by overheating.
I thought Golfs were reliable too, this one is my 2nd Golf, both were trouble :laugh:
Mine has been off the road all last week and is set to be off the road until June.
-
sh** this aint good news for me.. i wont be able fix it prob till 2 weeks then!! ill have to bus it to my exams too :angry:
pretty p****** off this hapening after a full service .. which they are meant to give a full health check :angry:
-
im going to actually head over to garage now see if hes open and have a chat thanks for reply mate...
ill update when im bak :smiley:
-
If its the water pump avoid driving it far or its goodbye engine.
-
right just went for a little cruise... gave the car a good push also... and the tempreture was stable at 90! just where it should be its not going up or down now! im completely confused now :undecided:
-
could be the temperature sender, this tells the ECU how much choke to put on via water temp
-
hmm i dont know if i should wait to see if the tempreture rises again or just change it?? :sad:
the car runs absolutely fine no juddering or idle problems or nothing.
its just the like when the whole engine shaked.. happened once then vanished :undecided:
-
do you have VAG COM to check if the temp sender has an intermittant fault?
If not I'd change it for piece of mind anyways, it's not an expensive part
-
nope got no vag com.. if i get one of ebay will that pick it up if there is a fault?
-
really sounds like the water pump, dont be deceaved as i was.
My car did the same but just got worse, started getting a little hot then dropping back to 90 then it was fine for days then it just gave up all together
Sorry for the bad news if its the pump but it should only cost around £140 to have it changed dependant on whenthe last time you had the belts done
-
you scared me now voodoo :cry:
im pretty broke for another two weeks so ill have to see how goes until then .. im gonna drive it tomorow and tuesday for my exams then gonna just park it up until i got the cash :sad:
why me :cry: lol
-
If it continues to run hot, you'll end up with a head gasket failure.
-
i know :sad: but its been ok so far today :smiley:
i know ill have to change it but i jus need two 10 mile trips out of it then its parked if the golf can give me that it may have hope stay with me for unuda year :grin:
-

exactly and if it warps the alloy head that will need skimming also as the slightest signs of overheating can warp the alloy head enough for head gasket failure !! not advisable and more expense :sad:
-
If your skint take the bus as you will be more skint if you have to pay for head work, not cheap
Sorry to scare you dude but better to be honest than give you rose tinted shades lol
-
I woud,nt risk driving it that far. Only drive it a small distance to the garage once you have the money to fix it. Not worth making a more expensive fix.
-
Your mad driving that and risking doing even more damage which will cost you s#it loads more to fix. Another reason why I wouldnt get a service dont by Kwik fit or similar if you went to a specialst they would have advised you about the water pump etc.
-
right just got to uni today... and the cars been fine the tempreture is droping a slight very very slight then going back up to 90 it drop to like 87 .. but it has not moved above 90 at all! :undecided:
im thnking it may actually be the coolant sensor.. as my mates told me if it was the water pump my tempreture would be off the charts and ill notice in change of the drive which i dont!
going to drop it to garage tomorow he said he will do a full diagnostics to find the prob
hopefully it wont be the waterpump.. :smiley:
-
just took it to three garages.. one was kwik fit :angry:.. they said it most likley is the thermostat sticking as my car aint overheating or going over 90 (the middle mark) but just slightly dropping to 85 and rising back to 90 can mean it is sticking and needs to be changed £35 all in :smiley:
other two garages junped to the water pump and said £150 before i could even explain it fully .. so im a bit iffy with them 2 as there both back of the alley garages.. but good ones at that well known around my area for there work...
now one of the guys told me it can be one of the fins on your waterpump is gone which is causing the tempreture to rise BUT it aint rising i told him its dropping! :tongue:... and so he told me check if my heaters and air con is working fine and it all was as normal .. so he said hell ramp it up and have a look tomoz...
so whats your verdict guys sticking thermostat or get the car ramped up and most likley have the pump changed?? :smiley:
-
Has anyone suggested you get it plugged into VAGCOM to see if the car its spitting out ant fault codes? Might point you in the right direction as to where the point is.
-
How many miles has your car done?
-
yep thing is i have no vag com.. so gonna get that done tomoz at garage too.. but all three garages told me most likely there will be no warning codes as im just have symtoms yet nothing has actually fully gone yet! :cry:
u just found this which is just teh symptoms i am getting poor mpg and temp dropping rising
http://www.golfgtiforum.co.uk/index.php?topic=88088.0 (http://www.golfgtiforum.co.uk/index.php?topic=88088.0)
if its the thermostat ill be over the moon as it will only cost £35
car has done 75,000 miles ben
-
TJG has replaced his thermostat himself, might worth asking him? If its all booked in though then I wouldnt bother and just let the garage sort it out.

I would get the waterpump and cambelt done now then mate for peace of mind and they reccomed doing them at 60k so yours is long overdue.
-
mine was already done at 60 k mate from VW by the previous owner .. had that clarified too so thats why i dont want to change the belt :smiley:
plus i can't afford it right now.. so ill change the thermostat see if that sorts it if not then ill have to go down that route
-
What about the temp sender??
-
could be the temperature sender, this tells the ECU how much choke to put on via water temp
:rolleyes:
-
Have you checked the Temp sender?
-
yep the fault is thermostat.. just took the car leicster and back to gave me no probs...
im happy aint the water pump :smiley:
-
sorry correction was the temp sender :laugh:... all fixed now :smiley:
temp is slap bang middle (90)and stays there now :smiley:
-
Hmmm, wondering if it's worth me trying the temp sender then, how much is it and where is it and how easy was it to fit?
-

About 30 quid from VW and a piece of pee.
-
I thank you :nerd:

£30 ant and you cant go wrong.. it sorted my prob out.. all the scare about the water pump had me going but sometimes its the little things lol :smiley:
-
From VW main dealers?
-
i got my from a VW/audi specialist shop for £13!!!! so see if you got one around urs they will have on cheap... come think of i dont think dealers is £30 i rekun it will be arouns £20 mark...
-
So when I ask for the temp sender, will I be presented with a myriad of temp senders? If so, which temp sender is it and where is it located? Any coolant to be lost?
-
should be a green one, I got one from ebay for £7 and had no problems with it.

yh there is either green or blue... but green 1 is the one you want.. check the link i posted before in this thread it gives you step by step how fit it and some info about it... :smiley:
-
I just bought my green onre from VW today. I'm nervous, will this cure it? I hope so.
I've not felt this nervous since asking my girlfriend if she'd like to try bum love. :embarassed:
-
:grin: :grin: :grin:
-
Well I've just replaced it, going to have a bite to eat, then I'll take it for a spin and see what occurs.
-
can you check your average miles per gallon on ur mk4???... mine was readin 25mpg drivin like a granny!!!!!!! after i changed its back to the 34-36 mark :smiley:
-
Well I took it for a drive and it's still over heating when the revs go up.
So, mine isn't the temp sender.
Basically, this could be the pump as circulation is obviously rubbish, as when I stopped and opened the bonnet, all was hot apart from the bottom hose, as the engine returned to 90 degrees under idle engine speed, the bottom hose become hot. This I wouldn't necessarily put down to a stat, but who knows, That's all there is, mechanical wise is pump and stat and electrical wise istemp senders.
:undecided:
-
hmmm only other thing thermostat! :undecided:
you taken it to a garage to have good check on it??
-
Garage can't see it til 3rd June :rolleyes:
Failing that I could try a dude where I work, but it's getting it there, I'll have to drive, rest, drive rest.
I'll probably get one of them to do the pump, it doesn't seem like a thermostat issue as once the radiator bottom hose is hot, it'll stay hot, as the car just needs a chance to circulate it there. I've no doubt, considering my symptoms and other peoples past issues, that it is the pump.
-
Can you see the water being pumped back into the coolant tank when you rev it?
-
yh if thats your symtoms then the pumps had a sissy fit :sad:
makesure to replace it with a metal fin one tho! as iv heard VW decided plastic fins would be a good idea on a water pump which is mostly why they end up dying :angry:
-
Can you see the water being pumped back into the coolant tank when you rev it?
It's only an expansion tank isn't it?
Besides, non cable throttle, so would have to get an assistant.
-
Can you see the water being pumped back into the coolant tank when you rev it?
The water should enter via the top hose still.
-
Can you see the water being pumped back into the coolant tank when you rev it?
The water should enter via the top hose still.
Well it probably does, at idle speed.
What I could do is try to see when it's first started, depends where this enters from, top of the radiator usually. I'll see, definatley pump if at idle it moves water and doesn't only when speed is increased.

I've ordered my new pump from Awesome GTi, £40 all in with delivery.
