Hi
I have been searching around for some information on how to resolve a temp issue I have been having.
The Symptoms...
1) Car starts up and after a few seconds the red low coolant light turns on. Check the tank and coolant is at the correct level, so to that effect I am changing the tank and sensor this weekend. Question is whether to use G12+ or what I believe is G40
2) The engine takes a long time to warm up, without the climate running, in either auto or econ mode. It sometimes reachs 90 however when the climate is turned on at the "HI" setting the temp drops down to a little over the 60 mark. We worked around this by setting the control temp to 25 - 27 and this resolves the issue a little and keeps the temp up a little more than the previous scenario.
The car had it's cambelt changed around 18 months ago and presumed that the water pump had been changed. I will check this with West London Audi to see if it was or not. If not, whilst I will not be impressed, I will look to get it changed for the recent metal impellor version at the earliest opportunity.
My initial attempts to resolve this have led me to attempt the following this weekend.
1) drain the coolant system
2) replace the expansion tank (Cosmetic decision)
3) replace the low coolant level sensor in the tank
4) replace the thermostat
4) replace the coolant with the current specified coolant
5) replace the temp sender whilst the coolant is drained.
I really want to keep the car tip top as I have been bowled over on the car's practicality and fuel economy after going for fast, thirsty cars for the last 10 years or so. I figure that whilst I replace the coolant (not one to believe that the coolant will last the life of the car) I can change all those pieces cleanly and hopefully resolve the issue.
I know that a failed thermostat and sender can have interchangeable symptoms so this is really a double check I am doing the correct things, if nothing else.
The car was scanned for error codes and was not able to fnd any errors. This was done with a code reader and VAG COM also.
I realise that changing all the components may not be the best way to try and resolve the issue, however I figure that a complete drain and refill with all the sensors will at least give me some peace of mind.
Any input would be greatly appreciated as I have a long trip planned soon and the temp issue is something I would like to resolve before I faced with being stranded on a motorway somewhere with a non functioning car.
Thanks in advance
