Hi all The engine light comes on my 996 every so often, then goes off a few weeks later. I wasn't to concerned as the car drives well. So I got round to plugging it into the Durametric to look at the fault codes.... I've got loads of codes, P1340, P1531, P0300, P0306, P0304, P0305, P1585, P1319, P1318, P 1316, P1317, P0301, P0303! The car drives very nicely, loads of power and seems perfect when accelerating and driving. Feels perfect on the open road. The issue I have is a "tapping" noise on the engine on idle and a slightly eratic idle - its not much, but its not perfect. It sounds a bit like my 1955 VW Beetle. I was running 5W oil, but also changed it to 10w a month ago, but the tapping noise is exactly the same. Car has done 96,000m. So I'm keen to look at the codes and fix as many things as possible! So today I removed the spark plug/Coil pack covers on both sides to remove a spark plug from each side, the idea was that I could inspect them and the coil packs to see if there old or visually worn out. The plugs were NGK FGR6KQE 4 tipped plugs, with BERU coil packs all round. The plugs both looked great, normal grey/brown looking colours. The coil packs were dated Jan 2013 and visually looked clean and tidy. **I've owned the car about 18 months**. I was hoping the plugs may look old and I could just replace those to see if it improves, a fair £40 and Id get to spend some time hopefully improving the 996. I noticed that one of the middle "tubes" where the spark plug goes into was a bit wet with oil - the other two were dry. I see that its possible to buy new tubes for about £8 with the o-ring seals. The 3 tubes on the other side all looked dry, so just one that's seeping it seems. I'll work my way through the list of codes, but if anyone has any advice on these codes id love to hear from you! I see one of them was for a fuel vent, so I'm hoping a couple of codes could be cheap fixes. Many thanks, Paul Dorset.
G'Day... new to forum and my first 911 after 40 years of dreaming and running too many various hot VW's and rotors : ) I have an early 2008 Australian delivered Carrera 2S that had a engine light - go to garage - come on after a rough idle and stall at the lights. I have done nearly 6000 k's since buying the car, and yes I have been using the performance, including a run down the drag strip a couple of weeks previous (13.3 @ 115mph) I have taken it to a local German specialist (we have no Porsche dealer nearby) and the fault codes that it is throwing up are P0303 (cylinder 3 misfire), P0302 (cylinder 2 misfire), P0301 (cylinder 1 misfire), and P0011A (Camshaft position system performance), with Bank 1 deviation 13 degrees ! The mechanic also noted P0401 (control deviation) and P0016 (Crankshaft to camshaft position) !!!! HELP ? The car has been dealer serviced annually and has 116000 km on the clock. To me it appears to run fine, from the drivers seat anyway, after reset the engine light has gone off and initially stayed off for a couple days then returned, hence took it to mechanic that looks after wife's GTI and sons Audi as they are all German trained and appear to know their stuff. (Good local reputation, that can't be said of Porsche dealer that is more than 4 hours away) The mechanic can't do anything for a couple of weeks so I have brought the car home on a tilt tray and was hoping someone out there may be able to point me in the right direction... He has suggested, stretched cam chain ?, broken chain guide ?, and suggested the only real option is engine and gearbox out before they can even assess what it is. Obviously I am a little concerned as this was a big spend downunder for what appeared to be an immaculate car... three months of ownership and I am looking at the engine out, many $$$$ with no ability to get a quote as they have no idea what the real issue is. It starts fine and I idled it off the transporter and parked it up. Any assistance or ideas are appreciated. Cheers.
So here's my problem. I've got a 2001 Boxster S with the factory 3.2L engine and ~70,000 miles. I bought the car in 2010 with 38,000 miles on it. I have it serviced regularly every 5,000 miles at the independent dealership, iAutohaus, where I bought it. They specialize in European luxury cars and I trust them as much as a person can trust a dealership, I guess. My wife drove out Monday from Phoenix to Albuquerque with no issues. After spending the night at a friend's house, she left to drive on to her final destination in Santa Fe. After leaving her friend's house, she called me saying the CEL was flashing and the car was running really rough and had very little power. She was close to an Autozone so I had her take it there to have the codes read. She called me back saying it read a P0303, P0302, P0301, P0300, P0304, P0305, and P0306. Which I know are misfire codes, on every cylinder. Well, while I was checking around to find a reputable Porsche mechanic in Albuquerque, I guess the Autozone salesman told her it was due to bad gas and to buy some fuel system cleaner and she'd be fine. I called her back to tell her what I had found mechanic wise, and she said she had driven it on to Santa Fe. She said it was fine as long as she stayed out of 6th gear and didn't rev the engine too much. I'm not real happy she did that. Anyway.... She got it to a mechanic in Santa Fe and he initially checked the coil packs. After clearing the error codes, he said the misfire on cylinder 3 kept coming back. He swapped the coil packs but the problem stayed with cylinder 3 so he began to think maybe spark plugs. That didn't help either. A compression test showed very low compression on cylinder 3 and a leak down test showed it wouldn't hold pressure. The mechanic is suspecting a broken valve spring, or worse, and is suggesting either a $4500 rebuild or find another engine. But of course, I'm in Phoenix and the car is in Santa Fe. Oh, and my wife, she is still there too. I guess I'm a little confused on how it can go from running fine one minute, to having misfires on every cylinder, to having no compression on cylinder 3. Although, I'm sure the fact that she drove it an extra 50 miles didn't help anything. I'll be leaving Sunday to go pick up the car, and my wife. I'm am an experienced mechanic, just not fluent in Porsche so I'm not sure if I want to tackle this myself or not. Do you have any suggestions on additional troubleshooting I could do or should I just start looking for a new engine?
