annoying red light what is it and how do i stop it?

[Ciaran]

i think it's the temp light but the temp guage says it is between a quarter and half only at half if in traffic but quarter when in normal conditions.
plus got 105000 on clock but uses alot of oil moved from max to min on the dipstick in 7 days. i know it leaks oil slightly but is this not taking the piss?

the temp light flashes when the water level is low, so try topping up the expansion bottle

if it still flashes then its a dodgy sensor and needs replaced.

Check the water level in your expansion tank (when cold).
This happened to my MK2 16v, when i started from cold the red flashing light came on and the engine was not even warm.
It turned out that i was loosing water from the cooling system.

it does loose some water but i check it every day had to put a litre in on sat and the same on wed. where is it likely to leak and what is the best way to check where a leak may be?

[Onge]

With the engine running check all of the hose joints for water.
Also check the expansion tank cap, the seals do go after a while

if your car is loosing that much water then i'd get it checked out asap!

check for leaks first off, then get a compression test done for head gasket failure

[Ciaran]

no head gasket done about 15k ago and no mayonnaise on the oil cap. il have a look the morn for leaking hoses or seals!

Ah, mine does that too. Sometimes.

Although its got water and no leaks, so I reckon its a dodgy sensor....

[Ciaran]

yes just checked the water again and stopped going down now was just probably settling in the system after  being run in again

If your red light flashes 4 times then its the same as mine and its annoying
