After having problems with the MAF (cleaned it, all fine I think), I have now the Tiptronic error coming up. After resetting, there is nothing unusual untill it comes again after one ot two days. Any idea what to do???

 

Have you read out the fault codes?

 

No, how do you read out the codes? Or better what can be the reasons that the error goes off?

 

You need to get it to someone who has a PST2 or PIWIS to read the codes. Local dealer or independant should be able to help you.
