power steering rack part number?

I can’t go into the VIN’s of the other cars but your car definitely has a GEN1 rack, now I am back at work today I could look it up using your VIN. That means the part number for a genuine exchange rack on your car is currently 1K1 423 055 MX and the parts system says you also need 2 clamps 1K0 423 933, 2 clamps N 908 349 01, assembly carrier 1K0 199 313 AL (a very expensive part), GEN3 adapter harness 1K1 971 111 AJ and if required, new consul 1K0 199 296 J. The racks that this selection of parts the MX replaces is a bit ambiguous as some should be CX which is GEN2 and a slightly different process but as far as I can see the list is

1K1 423 051 > MX
1K1 423 051 AT > CX
1K1 423 051 AS > CX
1K1 423 051 BA > CX
1K1 423 051 BQ > CX
1K1 423 051 CN > MX
1K1 423 051 BG > CX
3C1 423 051 > CX
3C1 423 051 T > MX
1K1 423 051 DD > MX
1K1 423 051 DS > MX
1K1 423 051 EA > MX
1K1 423 051 ES > MX
561 423 051 C > MX
561 423 051 M > MX
1K1 423 051 CC > CX
1K1 423 051 CP > MX
1K1 423 051 FA > MX
1K1 423 051 FE > MX
1K1 423 055 > CX
1K1 423 055 AX > CX
1K1 423 055 B > CX
1K1 423 055 BX > CX
1K1 423 055 C > MX
1K1 423 055 E > MX
1K1 423 055 F > MX
1K1 423 055 G > MX
1K1 423 055 H > MX
1K1 423 055 J > MX
1K1 423 055 K > MX
1K1 423 055 M > MX

AND I am sure there are many more, using a second hand one and working out its suitability is a bewildering subject!

GEN3 rack is too expensive and there is too much parts to be replaced. Do you have any experience if GEN2 is fully compatible with GEN1?

I have only ever taken off GEN2 right hand drive racks and replaced them with genuine GEN3 right hand drive racks. We were lucky that there seemed to be very few GEN1 right hand drive cars and most had been upgraded to GEN2 whilst still under warranty. I often have other motor traders bring me in cars they have fitted second hand racks to and sometimes it will not set up. If you fit a GEN2 LHD rack to a GEN1 LHD car, I think you need a different adapter harness to when you fit a GEN3, I get the part number as being 1K1 971 111 B and they are around 200 Euro.

I replaced steering rack. I fitted 2nd hand part from VW Golf -04 2.0 TDI, also wiring harness from same car. Now works very well, needed only normal calibration procedure, turning lerft and right and straight on few handred meters.

Hello, I have a problem with my steering rack too and i hope someone (especialle Crasher who knows a lot about it) can help me.
I have a Audi A3 07/2003 1.9TDI and I am pretty sure that my steering rack is a Gen-1.

I got a steering rack Gen-2 which part number is : 1K1 423 051 BE. So, in order to replace my Gen-1 steering rack with the Gen-2 steering rack i bought, I juste have to buy an adapter harness which is : 1K1971111AJ

Am I right ?

Thanks a lot

I have a Audi A3 06/2003 2.0TDI BKD and I am pretty sure that my steering rack is a Gen-1. 1k1909143j
What steering rack Gen-2 can i search, to fit the upgrade. My VIN code is WAUZZZ8P44A016346

You can fit any PQ35 platform rack.

I already tried with 1k0909144H 1k1423051EA and it doesnt work. Can u explain me "PQ35 platform rack", if i dont bother u too much. Maybe can u give me a part code, im not very skilled in terms of car parts. Ty alot

By PQ35 I mean the cars platform it is built on, another way of saying A5 but that gets confusing with the Audi of the same name and it is easier than saying Audi A3 8P, TT 8J, Q3 8U, VW Touran 1T, Caddy 2K, Golf/Jetta 1K/5K/16, Golf Plus 5M, Tiguan 5N, Scirocco 13, New Beetle 1C/9C/16, Eos 1F, Seat Altea 5P, Toledo 5P, Leon 1P, Skoda Octavia 1Z, Yeti 5L etc etc. REALLY, I should not call it a rack either, it is the "steering gear", the rack is the main part inside- it's a bit like people calling dampers shock absorbers when a shock absorber is actually the spring....

In what way did these parts not work? My experience of the PQ35 steering gear in left hand drive is limited and we had very few RHD cars with the GEN1 gear.

1K0 909 143 J, 1K0 909 144 H are not part numbers as such, more casting and internal use numbers on the steering gears electronics box. 1K1 423 051 EA is a "rack" and changed part number to 1K1 423 055 K, then 1K1 423 055 M and finally is now 1K1 423 055 MX.

What your car used new isn't really relevant, what should be done is repair it according to the VIN specific instructions laid out in the parts system which states to use 1K1 423 055 MX after handing in any one of a dozen or more units which are acceptable as an exchange, 1K1 423 055 EA is an acceptable "core surcharge" unit. To fit this GEN3 unit you will need the conversion harness for left hand drive, subframe to suit your engine type and possibly one of the wishbone consuls.

Hi there I have just recently bought a 53 plate audi a3 had the car 4 days and the power steering has stopped working kind of left me in a hard spot I've tried to look underneath with the use of a endoscope but can't see anything is there any way possible someone could find me the part number for the rack/control module on the car I'm after using my Vin would be a massive help

I've checked all fuses ect and had the car plugged in and the fault code leads to the electronicafter some discussion with friends
Thanks Steven
