New warning lights/Durametric codes - Should I be worried?

[slaskowski]

My wife used our 2004 CTT as a daily driver here in Miami which now has 80K miles on it. We bought it as a CPO back in 2008 and until recently has been very reliable. In the past year we have had the coolant pipes repaired after they blew and then had to replace the water manifold gaskets about four months later. We are looking to hold on to it for another year and will then trade it in for another Cayenne (love the new models)

There has been an issue with the warning lights coming on with the suspension for the past two years, however upon investigation it appears that it is not impacting the car and would be pretty expensive to repair/debug the actual cause.

Recently there has been a few other warning lights coming on with the car. I have reset them with my Durametric SW however they keep coming back up. Can someone help me what the following:

• What the codes are
• Do they need to be addressed now
• Are they difficult to repair?

My brother who is very mechanically inclined - he use to own a 1975 Audi 100LS so he fix anything :)

Removed comment as I just realised that the other thread I was looking at was started 2 years ago. :blush:
