My daughter's 62 plate Seat Ibiza 1.6TDi had a power steering failure. I checked all power etc and suspected PAS pump required changing, so purchased a spares recovered pump and fitted, only to find that this too didn't work. Time to hit the internet to find pump would require coding, so purchased VCDS. Initial scan showed pump was coded:

Coding: 10251
Shop #:WSC 00046
But also Fault coded 01656 - Crash Signal 35-00 - - .

After searching the internet again found Ross Tech post for

"01656 - Crash Signal; Short to Ground
Possible Causes
When found in AIRBAG VW71 vehicles such as the 1Y New Beetle Cabriolet the following may apply:
Short circuit in wiring to/from Airbag Control Module (J234) and ground.
Faulty Fuel Pump Relay (J17) and/or faulty Central Conv. Module (J393)
Airbag Control Module (J234) defective
Possible Solutions
When found in AIRBAG VW71 vehicles such as the 1Y New Beetle Cabriolet
Use the factory level wiring diagrams to check for a short circuit in wiring to/from Airbag Control Module (J234) and ground on the A125 "Crash Data" circuit. Note, all components must be unplugged before connecting a DVOM!
Remove the Fuel Pump Relay (J17) and faulty Central Conv. Module (J393) to see if this DTC will clear. If the fault clears, reinstall one of the components at a time to determine the cause.
Replace Airbag Control Module (J234) only after the wiring and all components on the A125 spliced circuit are ruled out as possible causes."[/I]

After much searching and ripping car apart, a re-seat of Fuel Pump relay recovered the PAS Pump and cleared the fault code, however steering seem to be lighter than what it was before.
Can anyone give me the correct coding for the pump?

Thanks

Do you have data from the original pump?

Have try adjusting the second-to-last digit of the coding, currently '5'?

1 = Heavy Vehicle (Normal)
2 = Sporty Vehicle (GTI/RS)
3 = Heavy Vehicle (increased Steering Aid at Vehicle Low Speeds)
4 = Light Vehicle (Normal)
5 = Light Vehicle (increased Steering Aid at Vehicle Low Speeds)
6 = Handicap Setting (heavily increased Steering Aid)

Thanks Uwe for your response. That had crossed my mind, but not had the chance to reconnect as yet. I expect the original pump is fully serviceable and could be refitted as the fault was the crash signal disabling the PAS pump.
