Coolant problem VW Golf GT TDI 2005 No explanation!!

[GolfTDIGT]

Hi,

If anyone could help, I would be grateful.

Car: VW Golf GT TDI 140 BHP 2005.

I have started the engine on a couple of occassions and the coolant warning light has come on. Checked the level and almost empty.

Put coolant in and drove around for only a matter of days for problem to reoccur. No signs of leaks BTW.

Took the car to my local main stealer yesterday and they pressure tested the system 3 times and no leaks discovered.

I bought the car recently two months ago for another VW Main agent in a different part of the country and have an extended warranty.

Have to say the local dealer were pretty good and didn't charge me a penny not even a diagonistic fee which should have been £50 quid or so.

They did report that car looked as if it has had a new radiator, don't know if the two are connected.

They also commented that very, very occassionally these cars can have engine faults!!

Any opinions?

Thanks in advance.

Any steam from engine or exhaust?

If its had a rad recently, could be air in the system bleeding out.

This is very comon when varius parts of the cooling system are replaced, its not always posible to get all the air out when the coolant is first filled after component replacement/repair. As the car does a number of temperature cycles, the air then comes to the top and you have to top up the level.

If it continues to drop could be a porus head or more likely EGR cooler leaking internally.

I had one as a company car. Same thing happened. The coolant never ran on the drive and the light would always come up during a long trip or in the morning when first started.

A warped head was diagnosed and had to be replaced along with some elements in one of the cylinders. Glad you have an extended warranty if it's something similar.
