Reported by Durametric software: 2100 servo motor for footwell flap Any suggestions?

would you mind sharing some analysis results? ;) Anything specific you would like to know (e.g.: TBN, ability to stay in grade, etc.)? Maybe ZDDP, Moly, Calc levels, TBN, and grade stability? :D OK, here we go with a couple of caveats: Our database has a lot more Syntec 10W-40 data than 5W-40 as the 10W product is used by most of our clients. That said, we do have a fair number of 5W analysis. The data was screened to limit the analysis to cars that see mainly street driving, and were not suffering issues (high fuel dilution, coolant infiltration, etc.). Oil analysis was all done in a local lab that handles both oil and fuel analysis. Virgin oil comparison – Other than the obvious viscosity differences, for the most part the 5W-40 and 10W-40 looked similar with a couple of exceptions: The TBN value was notably higher in the 5W product (~12.5 vs. 10.8), as was the calcium levels (1585 PPM vs. 1205). Moly levels were similar between both grades, with the 10W product being a bit higher (38 PPM), as were its phosphorus levels (943 PPM), which would be expected as Castrol promotes the 10W product as their premium full synthetic for “higher mileage” vehicles. 3,000 mile interval – Small but subtly different changes between the two grades, slightly higher drop off in TBN values for the 5W (both grades had the similar TBN values even though the 5W started higher, indicating higher degradation in the additive package), along with a drop in 100C viscosity for the 5W. Both products are staying “in grade”, but changes are larger for the 5W product. 6,000 mile interval – Differences between the grades are more noticeable. The 5W product TBN has lost over 60% of its starting value (it is beyond the point at which it should be changed), and the 100C viscosity drop in much higher in the 5W product. The 5W product is on its way out of “grade”. The 10W product still maintains a reasonably high TBN, better high temp viscosity; and remains “in grade”. 7,500 mile interval – The 5w product is well out of grade, TBN values are very low, as is the high temp viscosity. The 10W product has also suffered a bit, but is still “in grade, with a TBN value of 4.8. 100C viscosity is showing signs of dropping, but nowhere near that of the 5W product. A couple of observations: Obviously, the Syntec 10W-40 appears to be a better choice than the 5W-40. While not intended to do so, this comparison also seems to add credence to the old adage about not depending upon a multi-weight oil with more than a thirty point viscosity spread…………. very good analysis! i assume the wear rates should be similar in the same engine using either syntec 5w-40 or 10w-40. however porsche only recommends 0w-xx, 5w-xx grades. don you know of any particular reasons not to use 10w-xx? how about syntec 5w-50 which seems to be widely available as well and more stable than 5w-40? Porsche (like many OEM’s) “recommend” oils based upon multiple parameters including things like gas mileage and the life of the catalytic converters. While one would like to believe that engine wear and life are taken into account as well, it is impossible to determine what weighting they were given in the OEM determination of what to recommend, which is why we do not place a lot of faith in what Porsche “recommends”. Add into the mix the fact that oils constantly come and go from their preferred list, and you are left scratching your head. We base our oil selection on collected data and performance history. From what we have seen, the M96 does well on Syntec 10W-40 in terms of engine wear and longevity. Gas mileage and cat life can fall where it may, but the engines have to survive. My shop is in a cold winter climate area (currently about 20F), and we see triple digit heat in the summer; and we have a lot of cars running 10W-40 year round without issues, mine included. At the end of the day, the greater the spread between the oils rated weights places a greater load on the additive packages in synthetic oils. While the base stocks are important, wide viscosity spreads typically are totally dependent upon the additives, and the additive packages are susceptible to break down from a variety of sources. This is why you see postings about wide viscosity (e.g.: 5W-50) spread oils not living very long lives or standing up well under high loads. Very good. I will give syntec 10w-40 a shot in my v8 turbo, maybe redline 10w-40 as well, followed by some UOAs

cool! i'll keep playing with my durametric software :D

When I ran the ABS test under Durametric, there was a "ABS failure" displayed briefly on the cluster then disappeared, there was no errors in fault memory regarding ABS reported by Durametric though. I assume this was simply a jitter caused by running the test?

We have been using (and constantly testing) Castrol Syntec 10W-40; it seems to hold up well, so you might want to give it some consideration............... thanks for the recommendation. what do you think about Castrol Syntec 5W-40 which is on Porsche Approved Oil list?

According the UOA from BlackStone, the M1 0w-40 used in my 04 CTT for about 3000 miles basically sheared into 30 weight at 100C, TBN from 12 to 6 under normal driving condition. So this makes me wonder about the alternative to M1 0w-40. I almost settled on RedLine 5w-40 until I found out that people have been complaining about their recent formula change of removing all the molybdenum from this grade...

the warning disappeared after i unplugged/plugged the two relays in the fuse box next to the brake fluid reservoir :P no idea what they are. fingers crossed...

great! i will check those out ^_^

i used motor oil on my wrangler but don't think it's a good choice for cayenne. ;)

Thanks everyone, Just an update, the next day, the car doesn't start and the battery is dead. I charged for 18 hours and everything is back to normal. This is the second time that is happened to me. Is my battery needed to be replaced? how can you check if your battery has to be replaced? My Porsche dealer charges 470$ + taxes (part and labor) for the installation of a new battery...Any advice? Ian You can follow the info in the owner manual to check/replace battery assuming there are no electrical problems with your car.

RFM. This damper is truly available separately here in Europe :D The part number is: 955 423 389 00. The price is around 50$ and just a 3 minutes job to change it out. The solution for this problem is already in the post. It's just 50$.... Correct!! 955.423.389.00 Damper -- US MSRP $32.67 sweet OEM Catalog Item Number MSRP Core Price Price 95542338900 $34.38 $0.00 $28.87 DAMPENER, PARKING BR

what model year your car is? I thought the ignition coil problem only happens to 2004 and earlier cayennes

thanks. i guess i will keep looking...

Can a regular OBDII scanner read the error code?

Is this one in the picture the brake booster pump relay?

by the way, where i can find the "brake booster pump relay" to check? thanks.

saw this warning this morning when i started my 04 CTT what could be the possible cause?

$5xx for replacing coils + plugs (parts&labor) at an indi

interesting, they are local in bay area

oh well, $40 for a gallon... ;)

any good places to get redline? it seems hard to find in our local stores. Really? The following are quotes from the Redline website: For 0W40: "Recommended for water-cooled Porsche and Mercedes-Benz 229.5/229.51 applications" "Recommended for API SM/SL/SJ/SH/SG/CF and ACEA A3/B4" For 5W40: "As specified for Audi, BMW, Mercedes Benz, Porsche and VW applications" "Recommended for API SM/CJ-4/CI-4/CI-4 PLUS Also recommended for ACEA A3/B4/E9" I don't think they'd mention those ratings without being pretty sure they meet them. Wanna bet they their oils do meet the spec, but they've just never spent the money to formally get them listed? PS - I am biased, as I use Redline 5W40 in my Transsybera (GTS) V8.

sensors are good if they are not shot, causing the warning light to show up here is a link for cheap OEM rotor/pads sets pads + rotors
