If its the gauge next to the fuel gauge in your dash. thats your coolant temparature not oil. Thats what you seem to be describeing.

Classic syptoms of your waterpump on its way out. Have you had your cambelt changed? did you ask them to change waterpump with it?

yeah that right its the 1 next to the fuel gauge yea cambelt an water pump was changed at 46000 ish ive done 84000 ish so would that be the problem? i hav'nt tried it this morning but like i said it went red then light came on an bleeped at me but then took it nice an easy an stuck in inbetween 90-120 thanks for your help

They probably changed it for another plastic impellar one which after time loosens on the shaft so at high speeds the shaft spins and not the impellar so not circulating your coolant around the engine and overheating it.

And then on idle the shaft is spinning slow enough to spin the impellar so circulating your coolant and cooling your engine. Thats your problem i think, new waterpump!

the vag group have since improved the waterpumps and now you can get a metal impellar one which is best to ask for

Hope this helps

Hi - do you mean the water(coolant) temp gauge? If so it could be a sign that your waterpump is failing/failed


Sorry... I started typing this reply about 30min ago and I see it's already been diagnosed

 

[seatcupra2001]

yeah thanks but can i do this with out changing the cambelt or is it better to do it all in 1 go for peace of mind? thanks again jason

[seatcupra2001]

can i get bits from euro car parts? i.e cambelt kit an water pump?

 

[LEE69]

Yeah do the thermostat aswell whilst it is all apart, they like failing of late

 

[seatcupra2001]

im so pissed off just had a look at the coolent its near empty and theres a little puddle on the floor so would that defintly be water pump?arrrrrrhhhh

 

[LEE69]

No, not heard of the pump leaking, sounds like a hose as gone fill it up and re-check it

I dont agree with that tbh. VAG dont supply 1.8T metal impellar water pumps, never have. The replacement water pumps are modified and as yet I havent seen a modded one fail again.

I personally would use a modified genuine water pump over a pattern metal one any day of the week. You get two years warranty on a genuine one (as non gen is usually only a year) plus if it were to fail and cause engine damage as long as it was fitted by a garage with a VAT receipt you could well claim the engine damage back from SEAT, i doubt Unipart or similar would offer such a gurantee.

Mine is metal and came from seremotors a seat dealer on here.

Then I would think they supplied you with a non genuine one maybe?

Ill check but everyone i've ordered with the correct part number off ETKA has been plastic.

what fault code does vagcom state?

sounds like it could be a dodgy cts sensor...

naa nothin no fault codes apart from the normal 1 pressure drop between d.v but i think thats only coz i got a forge 007p

 

[james walker]

pressure drop isnt normal mate... but wont be casuing your issue either.

id be looking at thermostat or cts first before going waterpump tbh... but to be safe then pump change would be adviseable


have you checked the coolant hoses if you say there was a puddle?

yea i checked my hoses no splits or anything but wen engine is running water is still trickerling back into the coolent tank so the pump might not be gone?

 

[seatcupra2001]

oh an how could i tell my thermostat has gone?
