Lost central locking a few weeks ago.07 CRD Bitch would unlock and flash lights, but not lock again.
Lights flashed on pressing key button but no lock, and no lock at 24kph either.
Removed TIPM, disassembled, unsoldered the NEC TOKIN 10 pin relay ( new one purchased from ebay for 5 bucks } and put in a new one. (vacuum desoldering tool cost 200 its worth it...)
Crossed fingers, reassembled, and it actually works again!!!
Fuel pump relay replaced as well just in case.
Hope this info helps another JK driver.
