Hi all, when i lock a 2008 Cayman the horn beeps once. When checked on tester it brings up open circuit, fault present, 8050 passenger compartment monitoring, communication in rear control unit. I cant find any info on code 8050? Anyone have this problem before? It also has a current draw of .20 locked or unlocked. Any thoughts or test procedure info on this would be greatly appreciated. Cheers.
That's exactly what i wanted to do also. I think that would be a great start. Im not sure what ecu this has exactly other than aftermarket/performance. Who flashes back to stock?
Thanks I appreciate your comments. Tester is perfect. Never had issues and have been using it for years. I would have expected emission faults of some description but not 1 fault logged after car plays up. I find it weird too. I agree that it appears/sounds like a vac intake leak of some description. Ive always seen faults logged in every other issue, but nothing. Not 1 here?
Hi Loren im using a copy of Piwis tester. Use it on all cars. System tester working fine.
Any other thoughts out there?
Checked all faults. no faults in any systems. Removed diverter valves and checked. all work and hold vac nicely. Replaced both mafs, and cleaned throttle body.
My 04 Cayenne tt runs fine, but if i boost hard then brake hard, when i come to a stop it idles rough for a few seconds then sorts itself out? Chipped ecu, aftermarket exhaust. Lamba on both banks good at idle and boost. Any ideas? / help appreciated. Cheers.
