Just had it pop back again today - definitely a P1341 (not sure if this could be a definition issue with Durametric?) I searched online and did find someone else having the same issue, (green rubber in the filter, same P1341 code in a 3.4 996). They pulled the cam cover, looked at the actuator and sure enough, it was the o-ring coming apart. "Lazy" VarioCam, P1341 - Rennlist - Porsche Discussion Forums RENNLIST.COM 996 Forum - "Lazy" VarioCam, P1341 - UPDATE: IF YOU ARE SEEING SMALL BITS OF GREEN O-RING-ISH RUBBER IN YOUR OIL FILTERS, OR GETTING CAMSHAFT ADJUSTMENT CELs, THIS COULD BE FOR YOU. The last few...

Finally had the code come back - it is a P1341 - Porsche fault code 174 - Camshaft adjustment bank 1 below limit value

Is there a diagram of how it all goes together - am i right in thinking the green o-ring is on the shaft of the solenoid?

Ok so some variation of 996-605-901-00? Thanks again

Just to get in the right frame of mind - is this the whole ~$1200 USD actuator unit?

Thanks for the quick replies everyone! I will have a look at the electrical; however I tend to agree with a mech failure diagnosis due to the rubber showing up in the filter. a few follow up questions: Since this is very intermittent "fault" ( I daily drive the car and I might see the code once every few weeks) Is there a risk continuing to drive with this issue for the remainder of the season? Next, is replacing the seal in the assembly an option, or is this a full replacement scenario only? And last question, replacement part number?

thanks for the warm welcome - correct on the 2000 996. I am going to have to wait for it to pop back again to get the exact code as i neglected to copy it down - if i recall it was 1531.

Hi Guys, I have been getting a very intermittent Porsche fault code 174 - camshaft adjustment bank 1. Reading the forums it looks like this is one of the more expensive issues could be lurking. Before I start down that road, I wanted some thoughts on what I have been seeing in my data logs. (Durametric) Quick history: in 2014 @ 167K Km it developed a crack in the head on bank 1. Dealer checked head, mech could not find a crack and misdiagnosed it as a head gasket – which I argued was incorrect. Fix failed and long story short, there was an incredibly small crack, and they ended up covering a substantial portion of the labor / parts and discounted all of the “while you are in there” work I had done. In the first round in addition to the head gaskets, I had a bunch of other items replaced including most of a few cooling hoses, the AOS, Oil Cooler, Chain Guides and “Camshaft Brake Set”, IMS Flange. (Bearing was not replaced) On the second round the bank 1 head was replaced with a new OEM assembly with the complete gasket set, head gaskets again, all radiators, most of the remaining cooling hoses, oil pressure sender and a million other small gaskets, o-rings, etc. Now I am not 100% certain what is included with the OEM head, but I would assume they swapped over the cams, variocam solenoid, and such from the existing head. I am at just over 192K km and Bank 1 is now seeing this intermittent camshaft adjustment bank 1 code. On the first instance the car was running rough (lumpy idle). With the second two occurrences it has popped up with no noticeable indications aside from the CEL. After the second CEL, I dumped the oil and found some greenish grey rubber in the filter. New oil, new filter. Oil was less than 1000km old. Code has come back once. I have started logging to see what is going on – both banks are being logged as I wanted something to compare. As you can see, bank 1 is very slow to respond. Bank 2 seems to trigger instantly. While this is just a snapshot, this is what happens every single time (so far). Thoughts?
