how many miles to pass emissions after water cooling repair?
Not entirely sure I understand your question but if you are asking how many miles you have to drive after having work done on your engine to pass emissions test...0. It should pass immediately unless there is another problem. And what is 'water cooling repair'? exactly?
Thanks for saying all that, David- I think the problem here is something else than a "cooling repair"- the real problem is that it's an old Audi- good luck with those emissions tests
If this is a 1995 or older model you can take it through right away. Just make sure the engine is at normal operating temperature (195°F). If it's a 1996 or newer model and either the computer has been cleared by a scan tool or the battery disconnected it will take about a week of normal routine driving to set the readiness monitors so you'll pass emissions. During this time keep the gas tank between 3/4 and 1/4. No more and no less! This must be done to set all the readiness monitors. HTH. -Jim
