996TT using Water
Discussion
Anyones 996TT (standard) use water?
I checked for the first time after the service and it was below minimum. Okay, I thought, lets fill it to max, but a couple of days later it is down to below min again. Fair enough I was lapping the Nuerburgring in between and completed the drive back to the UK, but is this normal?
The car is not complaining and the temp gauge is rock solid at just a smidge over 80deg (infact it never seems to move which also worries me). The fan kicks in when needed and it seems to be running fine.

Did they do any work to the coolant system during the service?
If so it can take a few weeks for all the air to bleed out , may need one or two small refills before things stabilise.
I was losing a small amount of coolant and the opc confirmed it was leaky pipes , just a few pence to fix really but it took a while for the coolant level to settle again.

I had the same problem recently:

and my problem was solved when I tightened the two drain plugs that were leaking under the engine. If you look under the engine you will see two coolant pipes with a hex head plug in each. There might be a whiteish residue around the plugs indicating a leak. Could be a number of other issues.

Mine was leaking a very small amount, I would top it up to max and then next time I would check it was down to min level.
During the major service it was pointed out the expansion tank pressure release value was at fault, which they replaced. I have yet to check it the problem has been fixed.

Do you get a smell of coolant (antifreeze - sweet smell) at the front of the car when you get out of the car after a good run? If so then likely to be one of the 3 radiators.
I had 2 rads on a C4S (4 years old) and 1 rad on a TT S (2.5 years old) leak. None due to stone punctures but down to corrosion caused by leaves and debris getting stuck in the rad.
These are not covered by warranty if the fault is due to corrosion! Although the OPC did put a good will claim in on the TT. Up to £1600 to do all three, so you might want to live with it if it only weeps!

Shouldn't the car alert me or behave differently though if the water level drops.
It seems to depend on how much coolant you're missing and how you're driving your car. My low coolant light came on only once , and I've seen the level much lower subsequently , but I was trying to clear the pipes pre-NCT (Ireland's equivalent of an MOT) when the light illuminated.. 
Worth having a good check for leaks from the rads first then clean out any debris in front and behind the rads before you book it in to OPC, you then have a good chance of getting the rad[s] replaced under warranty. OPC'/ Porsche know the rad material is poor and will submit for warranty if they find no stone damage or rubbish [leaves, paper, road salting grit especially] that has been left to accumulate in the rads and caused external corrossion.
I had 1 radiator replaced in Jan ( and I may need the other side replacing soon ). It was done under warranty due to it being corroded. They will NOT replace under warranty if it is stone damage. This was made very clear to me when I took it in.
Just wanted to query the previous post stating that they wouldn't do a warranty fix if corroded.

My C2 was similar. I would top it up and it seemed to get rid of water to just below the min mark. I learned however, that it then NEVER moved below that! It just seemed to find its natural level, so I left it at that.
I only had the flashing low coolant light on once and after switching off and back on again it was fine. I was told that when hot and being driven hard, the system can expand enough that it will trigger the sensor, when really it is fine. These systems hold loads of water, IIRC around 20 odd litres.

Benaldo, are you trying to infer that by suggesting cleaning the rad areas carefully before submitting to OPC as potential warranty claim would 'help' with a decision?
'external corrossion is an indication of lack of owner following approved maintenance program'
What is involved in following an approved maintenance program for the rads? sorry if I sound it bit naive, I am new to Porsche ownership and would like to know if I should be following a set maintenance program, other than normal servicing.'external corrossion is an indication of lack of owner following approved maintenance program'
