Some early problems with my Turbo...

[Porschekid]

I picked up a 2001 Turbo with Tiptronic transmission and 70,000 miles a few weeks ago. It passed a PPI from Porsche but I've already had a couple problems (not sure if they are related).

The water temperature sensor doesn't appear to be working properly. After driving for many miles (should be at operating temperature) it will sit on the line between 100 and 180 and I know it should be closer to 180. A few times it has been up to 180 but it's rare. It has come up twice with 'failure indicator'.

Yesterday, on the highway I was going about 70 with cruise control on. I turned off cruise control and immediately got a check engine light which is still on today.

I filled up the coolant reservoir because it was below the minimum line but I didn't have to add very much and both problems remain. Also when driving about 65-70MPH with cruise control on (~2000RPM), my oil pressure sits on the 5 line. I'm not sure if that is normal but it seemed a little high to me.

The car itself seems to be running strong with no smoke, noises, or symptoms. If anyone could point me in the right direction it would be extremely appreciated.

Oil pressure at 5 on the highway is normal, the water temperature should be sitting at 180.

I'd go to Autozone and have them read the codes (check engine) and come back and post the codes. The guys here are good at interpreting them.

I had the code read and reset...

P1411 - Manufacturer Control Auxiliary Emission Controls

Any ideas?

Plenty more when you do a search, this forum is great for that! If you contribute you also get access to TSBs ect.

Thanks for the help Danyol. Odd that everyone had P0410 code with theirs and I only had the one... I guess I'll have to see if that light comes back. I do seem to still be having the water temp problem. Although, yesterday afternoon it was almost 80 degrees out and my temp seemed fine and this morning it was 45 out and it was only slightly above the 100 line after a 30 minute drive to work.
