I need some advice on what further tests to do before I start disassembling the camshaft. The code is "1341 = Camshaft adjustment Bank 1 below limit value." But I think this is misleading. Normally , this would be just a failed Solenoid or Variocam actuator. Btw ,these comments apply equally to a Bank 2 fault. But if you look at the Durametric data below ,there is a hint of a cheaper but much more stupid error. I recently rebuilt the engine. It runs beautifully. But has only run a few hours because I can't get rid of the 11341 fault code to get a Smog Test. The Actual Valu
9A1 105 308 03 VVS (02 superseded by 03 variable valve system actuator) Anyone replace one? What are the symptoms? How do you identify which one may be lazy? How many per bank? The PET digram denotes (1) so I assume that is one per side no? These appear very easy to replace as the sit next to the spark plugs. I will be doing my plugs in a few months, early spring so I am thinking of just swapping these out. The reason is that pesky hesitation I get under moderate load at around 2800 RPM. The dealer, as others on various boards, think it is the variocam transition. This looks like ab
Car in question: 1999 C4, M96.02, 41k miles (had it since 20k miles), original/stock IMS bearing Alright, so I stumbled on some posts regarding durametric readouts for camshaft deviation to check into the health of the IMS. I remembered I logged a bunch of real-time parameters back in 2012 just to establish a baseline with my new Durametric tool at the time. I finally found my old hard drive with the data and to my surprise, my camshaft position 1 deviation read -8.97 cold at idle and varied down to -9.53 when driving around. Camshaft deviation, position 2 is solidly at -3.19 regardless of en
Hi, I'm new to this forum and would like to discuss a subject concerning the variocam in a '98 C2 996. I want to buy this car, the only issue is that the onboard computer shows an error/ report concerning the variocam. I had the car checked at Porsche, they told me about this. The engine is running fine and there are no other problems with the car. Is it safe to buy this car, or should I have the seller to check/ repair the error ? The seller is providing a 3 month warrenty, but I won't use the car on a daily base. What would you advise me to do ? Joost
