Means code p1643

p1643 is a system check ok and is not a fault code and is always present

If you find code 18051/P1643 in the engine ECU you have to check the fault codes in the memory of the central electric computer which is VAG-COM group 09.

Sounds like low on oil but i dont think this year has a dip stick and its a dealer only job to check the oil level but with a funnel and a breather on top of the gearbox you may be able to add a litre and try it ??

P0163 O2 Sensor Circuit Low Voltage (Bank 2 Sensor 3) most likely a faulty sensor

sound more like an alternator problem

T.C.M. traction control module defective, check all wires/connections to the transmission for broken/loose wires/connection. if nothing found, test the T.C.M. (traction control module) to determine if it's faulty, if it is, replace it with a new one. if not, test wires/connections between the T.C.M. and E.C.M. (electronic control module)

p1643- fuel pump monitor circuit low input / p1745- line pressure solenoid system. this is starting to sound like a ecu issue. i would verify fuel pressure and double check your fuel filter. start there.

do a search on yahoo for jag codes there is a whole book of them

code p1111 is system pass code p0333 is knock sensor 2 high input (bank 2) code p1643 is can link engine control module/transmission control modual circuit/ network also see if your car has a fuel pump shut off switch also other safety features on cars to protect against damage trans and oil fluid pressure also ckeck your neutral safety switch

Hi

Gearbox is a sealed unit now, from the factory, so no topping up possible.

Sounds like major problem in transmission.

Time to say goodbye, while it is still driving !

Good Luck !

A FixYa Rating would be appreciated thanks !
