CEL after 6 years

[Anker]

So I must have the all systems version.

Ideally Durametric is the best choice. I have a Durametric, another general purpose reader and a cheap blue tooth reader. The one I use the most is the cheap blue tooth reader w free software. At least you can read the codes as a starting point. If the cheap unit can't read or reset the code then you could look into Durametric. I have a vacuum leak code that pops up from time to time and when the CEL comes on it's easy to check if it is something more serious and a quick reset from cell phone.

Hello everyone

I know as some of you pointed out and from what I have read that the Durametric is probably the best after market tool for Porsche cars. Its Porsche specific I believe. The one I chose after reading about it (prompted by Ankers purchase) was the Autel MD802 all systems tool. I chose this in the end because it seems to cover so many vehicles as well as Porsche.

I tried it out the day after I got it and it found the fault right away. It read "P0139 sensor aging behind cat c bank 1". So it looks like I need a new 02 sensor on that side because the old one is tired.
This is early days I know but it seems simple to use up to now.

Hello everybody

I just thought I would post how things are going. I replaced the 02 sensor on the drivers side. In the manual for the Autel tool it says you can delete the codes, which then I assume the CE light goes off. That is what I was going to do when I got home from work. On the way home however the CE light went out itself. I suppose this tells me that the new sensor works and is communicating the right info to the DME.
My question would be then, does this happen to all repairs of sensors, is it best to wait for the light go out itself after the repair or replacement. Or doesn't it matter.
This is all very basic stuff I suppose to all those of you who have been using diagnostic tools for years, but to newbies like me, its a big learning curve.

Works with some MIL lights, but not all. Some have to be manually reset.

Thanks JFP, I will bear that in mind. Is MIL an American abbreviation?

MIL stands for "Malfunction Indicator Light", and is a widely used term in automive circles. While most are used to CEL for "Check engine light", it only refers to one light. MIL applies to all of the "idiot lights" on the dash(CEL, airbags, seatbelt, your car payment is due, etc).
