Parts required:



1. ESP hydraulic unit pump. I paid €35 pounds on ebay
This will replace the old ABS Pump
The pump was from an GP 1.4 Sport (there are more compatibles)
The code on it :
BOSCH 51787092 0 265 234 512
Fiat part number : 71746431 (been substituted 71746362)

There are many ESP units that are compatible. The problem is the there is no Fiat part number on the units only Bosch. The Bosch automotive catalog vehicle search, web site is of great help you fill in the details and it will show units that are compatible with your car. ( View vehicle equipment then select suspension. In Eper Abs units that have ESP will have the 392 code VDC.

From photos you can tell if the unit has ESP as it is written on the sticker on the pump and also from the 2 large inlet pipes that are in the middle of the pump and not on the sides. That’s why you also need new brake pipes.


2. Hydraulic Unit bracket. Fiat part number: 51841910


3. New brake pipe between ESP unit and brake cylinder, designed for ESP. Fiat part number :51796558 and 51855955 price €16+€21.

7. Steering Column with position Angle Sensor ESP/VDC €130 from ebay
There are many Steering units that are compatible as long as it is from Grande Punto. Very important the steering column must have steering position sensor. You can easily tell by looking at the photos of the units. The ones with the steering angle sensor (for ESP/VDC) will have a blue, purple or orange colored sheath from the torque sensor cables that connect to the steering ECU. They will also have 7 cables. The one with no steering angle sensor (No ESP/VDC) will have white or yellow and only 6 cables. There is also a newer version in which the torque sensor connection is made inside the unit. There is no sheath visible. The only way to tell if it is for (ESP/VDC) is by taking the Fiat part number and searching in Eper. If it shows the 392 VDC code and when you click on the item 2Y which is Grande Punto then it should work. The one I got was the newer ones.

For connecting wire I do not like to use wire taps I think they are not safe. I prefer remove the insulation from the wire spread the wire strands making a hole in the middle then twist the new wire in the middle cover with self amalgamating tape and then wrap fabric tape.
