True synthetic engine oils use poly alpha olefins not a petroleum mineral oil. Think polythene ie poly ethylene. Different molecular structure but same principle ie polymerising small olefin ethylene, C2H4, to make a bigger molecule. A process developed by Mobil OIl for their famous Mobil 1. Semi synthetic engine oil uses a hydro cracked mineral oil as developed by Shell/BP. The hydro cracking converts aromatic hydrocarbons, to parafinic hydrocarbons which don't degrade as readily as aromatics. Shell/BP had to stop calling their hydro cracked engine oils" full synthetic" following a court case in Germany. Not a lot of people know that 😊

Sorry for the tantrum ! Fitted side sensor and central control and 2.2 ohm resistor in the socket. Air bag light went out . Fitted the seat with the replacement air bag and light flashing. Did the ignition on/ off sequence posted on the forum and now light goes out as it should so now legal and safe albeit with ripped seat side panel

Well as no one could be a...d to answer or even acknowledge this plea for help including Mr. Superman, I know everything Z Manalex, I ended up taking out lots of unnecessary stuff before I found the unit. This is for a roadster. Behind the seat is a panel, 21"x 12" held in by clips. Sprise this out and you will see a circular 10" hole. Through it to the left you will see the seat belt " roller" which is held in place by a 14mm bolt at the bottom and , a difficult to reach , 10mm bolt at the top. Once the seat belt roller is pulled away you will see the crash sensor unit behind held in place with two 10 mm nuts. Following my track day side bang I have replaced this side impact sensor ( ebay 2nd hand),am replacing the in seat canister unit ( e bay 2nd hand) and have had the central programmer wiped . Will let you know if light goes out ?? The cars or mine !!!

Please help. Where is the drivers side impact sensor on my 350Z convertible. In 2017 MrGR13 asked the question but I can find no replies or others on issue. if it is behind the b pillar interior trim, how does it come off. Have pulled away rubber door surround but frightened of breaking by heavy levering Jeff

Did you ever get a reply as to where side impact sensors are ?

Hi,every track day my ecu esp and tcs lights come on. Think gets overheated. Peddle dance or Ob gets rid of ecu and usually esp/tcs goes off after cooled down. At Cadwell my car started bogging and I struggled to get off. After cooled down it was ok. Think esp was so overheated it kept slowing the engine. Had a track day crash and afterwards,after a short distance the skid light would flicker and then both lights came full on Steering wheel not central. Had car tracked and no lights since. Perhaps your stressful use has damaged a sensor. Suspect if my esp had been working i wouldn’t have crashed. Poor excuse. Good luck Jeff

Thanks for your replies and now have an one that works with my 350Z. My earlier post of complete electric failure was down to a problem I believe /hope with the "main +ve fusible fuse link" which I have replaced. See you Tube for details.

I had similar problem but mine showed engine light and ESP/Skid icon. Test with friends meter showed crankshaft sensor which I changed. Sensor from e Bay was £35 not £100+ from Nissan. I had not noticed a particular problem but once fitted start up was quicker and smoother

thanks Rod. Based in Woodbridge Suffolk. Used to know your part of the world well. Lived Hadleigh then Latchingdon and worked for Mobil at Coryton. I shall buy the unit you have as it works with IOS not just Android. I have now made progress on my total electric but intermittent electric failure. You Tube to the rescue. It's a problem with the " main+ve battery fusible fuse link " unit. Common Nissan problem with older cars. Replacement ordered. Jeff

All the links from earlier posts to e Bay/ Amazon for OBD scanners that work come up " we have looked everywhere but can't find" or if the scanner comes up " currently unavailable ". Can someone advise me of one that works for the 350Z which is current. Trying to solve problem in my earlier post, Complete Electrical Failure

Has anyone experienced this. After 80 miles around Brands Hatch so car pretty hot ,I went to refuel, then car would not start. Nothing, no ignition lights . Checked battery connectors all ok. Tried jump start, nothing , no ignition lights all completely dead. After 15 minutes standing it fired up. Returned to circuit, 1 mile , switched off, would not restart, as before nothing. Boot lid wierdly self locked. Disconnected battery, reboot ?? After 15 minutes started. Set off home but after 60 miles as cruising along suddenly no power. Engine running but wouldn't go above 1800 rpm. Luckily got to a layby, engine running and all warning lights had come on, ABS, ECU, Traction control etc. Then it stopped and would not start. During 2 hour wait for breakdown, kept trying it, nothing. Break down chaps battery booster and it fired up. Showing 14+volts charging . He brought me home and car started. Car started this morning but to 2-3 minutes for it to show 14V+. Breakdown chap said when lights all came on usually alternator not charging but it is. Also did not tell him about my earlier problems Any ideas as daren't risk using until get sorted

Thanks , car is all standard

Many Thanks ZMan, you are such as source of help for us 350Z owners. Jeff

The front Y pipe on my 2005 convertible needs replacing. Exhaust companies cannot locate a source. Ones on internet only fit coupes. They look the same as mine. What is the difference ? If just fixing brackets maybe can get fixed. If different connections then a problem. My car's exhaust is standard so no point in fitting high performance section. Any info. suggestions Jeff E
