Fault code 29dc ?

You should check out www.reliable-store.com they have info on repair,
service, wiring diagram, electrical diagram, fuse diagram, troubleshooting, PCV, owner's/service/repair/parts manual, fault codes, error codes, etc everything on all vehicles. must check it out

You need to clarify the fault code, as the 'f' is not valid.
Removing the 'f' gives 10 possible fault codes (0-9) ranging from manifold flap issues to the Evaporator circuit (relevant for diesels?) to the exhaust DPF needing a regeneration...

Here's a link to your P0650 code. http://www.obd-codes.com/p0650

The car should still be under warranty if a 2014 model so you should be taking it to a dealer to have it checked and rectified.

in my car Vauxhall zafira this cod comes up which is u2100c and can u please tell me how to fix the problem , I change the car key battery . still the light is there.

You mean Po077?

this means that it has detected a rich condition. You can get this with a dirty maf sensor suually caused by paper filters, a vacuum in a hose or connection or a fuel pressure problem.
Dirty mafs are easily cleaned even at home with maf spray cleaner. As long as you are careful not to physically touch the actual'sensor you can't hurrt it if it is still good.

Was the code P1352 (ERASED) after the repairs were made? After all repairs are made for any (DTC) the code must be must be erased from the cars computer (ECM),other wise the cod will keep comming up as a stored trouble code.I hope you find this helpfull.Good luck.

you need to input the CODe into the unit to make it work.
