ave searched on the forum and read the temp sender problem but just wanted to check iwhich one i needed to do
basically my temp needle keeps goign between 0 and 90 as soon as i stop driving it goes to 90 or it just fluctuates instead of stayign at 90 sometimes when its warm it stays at 0... how dangerous is this or is it ok to drive for a few days till i sort it out
do i need to apply this guide to it
thermostat

Does it blow hot air?
-
kind of answered your own question but you need the temp sender guide
thermostat and temp sender are two different things :smiley:
-
yeah blows hot air... i just ran one of them obd memoscan scanners on it and it didnt show any fault code

buy a bottle of G12 from the dealers - make sure the engine is COLD before changing it! you'll loose a little but not a lot of coolant
-
ta m8 dam stealers better have it in stock tomorrow.
u know the g 12 thing do u pour that into that think that looks liek a feed and expansion tank on the left of the engine in a see through round thing. sorry dont knwo the technical term for it

they will do or they shouldn't be dealers!
its called the expansion tank - you will need to dilute the G12 slightly - ratio's are on the back of the bottle
-
alright cheers. its called a expantion tank .....am a civil engineer by trade been designing a lof of HVAC systems at work f**k knows why i called it a feed and expansion tank!

well it does regulate the coolant around the system so i guess technically you are correct
i'd suggest buying a Haynes manual - not great but will give you a better idea of what things are and where they are :smiley:
-
will the haynes manual tell me how to change the boot/lock and handle over?

Weren't on the back of bottle. If your changing the temp sender you'll only lose about 100ml if that. Really easy t do.

It was on the G12+ i got from VW :undecided:
-
Yeah, will only spill a table spoon, tops, when changing the CTS! :afro:
-
defo on the bottle of genuine VW G12 as i filled mine up today its 2 parts coolant to 3 parts water
-
Weren't on mine, just double checked. Mine was G12 plus plus....
-
anyone got a part number
-
Weren't on mine, just double checked. Mine was G12 plus plus....
Strange :undecided:
-
GO12A8GM1 - is the coolant I got.
TEmp sender number is in the thread with the guide.

did you get it from the dealers?
-
will have to tomorrow
-
G12 plus from vw = G 012 A8F M1
-
VW Part numbers : sensor 059919501A - Green And old style blue : 059919501
Both cost about £20
"C" clip: 032121142 cost about about 40p

Yeah, get two of hose C clips as one may break! and at 40p it's stupid not too. I changed mine and the first clip i removed pinged off somewhere, went to put new on an dropped it. Looked under the car and found half a clip. Managed to find the other complete one hiding in the front valence!

can a faulty temp sender result in low mpg i just doen a round trip of 50 miles at 70mph returnign only 43mpg... or is this due to the bigger 18s?
-
Yeah it can
-
Yes it will cause bad mpg but the 18's will knock a little bit off to
-
Yes it will cause bad mpg but the 18's will knock a little bit off to
just done a 100 mile round trip at a constant 75mph and am only getting 42mpg now this is after changign the tempo sender, i didnt know that the 18's on 225's woudl knock as much as 8-9mpg's off thats quite a lot.... i was thinkgin maybe change MAF but i was hoping the new sender woudl sort it out and it has done but only slightly i think my last sender was temperental ... but never thought the wheels wud make such a big difference!!!!
any ideas?
-
drive slower :grin:
at about 65-70mph I get around 50mpg ish
Changing the maf might make a difference.
-
accordign to parkers the
anni 150 tdi still returns 52mpg same as the golf 150
and the anni runs 18 wheels so how coem my mpg was piss poor when i was just drivign sensibly

oh right suppsoe all test are doen at 56mph but still i used to do 80 and get 52mpg... and now if i do 80 i only 44mpg!!!
what figs do u get on ure 18s at 80
i suppose u always gotto compensate soemwhere and if it mean sloosign 8-9 mpg for the looks ill take it cant beat the grip though even in wet sticks to the road proper nice!
-
If I drive home at 80 I get about 45ish mpg
your right about the grip :cool:
-
right so @ 80mph = approx 45mpg ... that means theres nothign wrong i.e maf etc and its just normal to loose around 7-8 mpgs then......gutted but u cant beat teh grip and looks ...
i was thinkign of changign maf but if that teh norm then screw it
cheers pd.
-
what was the ambient temperature like?? (outside temp)
in cold weather diesels take a knock on mpg - my last tank over the really cold spell i just scrapped 500 miles from the tank :undecided:
-
I noticed an improvement in mpg this week with the slightly warmer weather. I've done just over 1000 miles in the past week and used £110 worth of v-power diesel so not to bad
-
dunno rhys i think last coipel of days its been quite mild round 5-7 degrees i think

hmm sounds about right then - was your journey quite hilly? mostly dual carrigeway??
-
no it was just flat m1 the usually trip on my 16s at 80mph woudl of got between 51-52 mpg but with these on i got 43mpg... i was thinkign of changign the MAF until steve pd says he get s the same around 43-45 so i guess thats the price u pay...one last thign i coudl check is in the service info thread under mk4 maintence thread rich says
'.....If running 18" wheels using the 225/40/18 you should run 34 psi all round to compensate for the lower profile tyre'
and i think the tyres place inflated them to 32psi all round but i mite be wrong!!!!
this also means parkers guide isnt right coz the anni runs on 18s and it shows mpg as the 150 tdi?
-
Is it due a service soon?? :undecided:
How about taking the maf off and see if its dirty. Mine was dirty/oilly, i cleaned it with Isopropyl Alcohol :wink:
it probably did help.
I took it off again a couple of weeks ago to see if it was dirty again and it looked ok.
-
mite pop into vdub and get a new one cant be arsed fannyign about cleaning it but i think its the norm to loose mpgs if u keep it in the 80s and its not due service for another 5k
