This isn’t going to help. Well need the VIN for the C4GP that you need the part for, then we can tell what the correct part should be and then cross reference with it these.

There are different modules depending on year and spec.

I seem to of found that out looking at the different numbers that all say they fit the c4gp
Mine is still institute so can't find any other numbers
Reg is Vin VF7**************[VIN obfuscated, can be read by forum staff]*******
Cheers
First am replacing brake switch with loom then this if abs/esp fault continues

[Gibbo2286]

What symptoms do you have with this other than the light? I found that replacing the sensor usually isn't a cure.

I have the esp abs warning also the handbrake fault
Cruise control non operational
And I tested and I definitely don't have any abs
The handbrake can be put on manually but if I don't turn it off as I turn the ignition on it won't deactivate
And the footbrake warning light comes on to say I am not pressing it
I have had the blue wire repaired but it looks like it had already been repaired in the past
So am doing the switch first and a total rewire from fuse 7 I think on battery to abs unit
Then if not the abs esp ecu module if I can find the right one

Ok, so none of those are the correct ones for your car.

Your original Part for the Hydraulic Block was 4541EY; this was later superseded with a replacement part, no: 4541QE

So searching on those should bring up the correct one, however Bill(?), I would really look at other areas first as these are extremely reliable and secondly, an eye watering £600-700 second hand and £1516.97 inc. VAT new!

[bigbill00]

I am trying other things first
So it's the complete block and ecu
Those other parts where just the ecu module
So if needed I need the complete pump valve block and ecu in one unit
Cheers for all your help

Yes on this model it is a combined unit, no separate parts. If you are not getting any dialogue with the ABS / ESP ECU, this can be down to the VCI and Diagbox version you are using. What version of Diagbox are you on? 7.57 should be fine for your needs. There are also corrections made with later software versions that prevent communication with the additive ECU , so don't discount this. If you have the version of Diagbox (top right corner) I should be able to see if these were corrected.

Same again 30 brand new but not for mine even though seller says different lol
Always worth a check with people in the know
Thanks for all your help
Am sure once I've fitted switch and rewired I will be back if only to update post many thanks for your time

No problem.

Unfortunately sellers just want to shift their gear and in many cases just copy listings from others when the part although looking identical will not be compatible. Things like Hill Start Assist, Stop Start, Electronic Parking Brake, particular wheels fitted, engine type, suspension system, fuel injection and additive system - all these have an interaction with the ABS / ESP ECU as this affects calculations used by other ECUs.
