These control modules are fitted to 2.2L HDi and Multijet models manufactured between 2007-2014. Unfortunately, they’re particularly susceptible to developing internal faults that cause a range of engine-related problems, including non-start, cutting out, and an illuminated EML.

When failure strikes, it’s common for a handful of DTCs to store - including P0200, P0603 and P062B. Thankfully though, whether you’ve got a Fiat Ducato with P0200 stored or a Peugeot Boxer with P0603 stored, if a DCU-102 is the source of your problems, then we can help.

Send your Visteon DCU-102 to us for comprehensive testing – we’ll let you know if a repair is possible and carry out a functionality-restoring rebuild within 2-3 working days. Just fill out our short test form to get started.

Visteon DCU-102 fault explained
These engine control modules are particularly susceptible to developing internal defects much earlier in their lifetime than you might expect.

When your Visteon DCU-102 is in need of repair, it’s very unlikely the engine will be able to run smoothly and consistently, if at all. In most cases, the engine warning light will illuminate as a result of stored DTCs, such as:

• P0200 – Injector Circuit Malfunction

This code is stored by the engine ECU, in this case a Visteon DCU-102 in need of repair, when it has detected abnormal behaviour in its injector driver circuitry. In some cases, the accompanying diagnostic message might reference ‘open circuit’ or ‘short to ground’ depending on the specific tool used.

The P0200 DTC stored in your Peugeot Boxer or Fiat Ducato is, in most cases, triggered by a DCU-102 fault. When these control modules fail, their ability to accurately switch the current path to the injectors is hindered. This of course significantly disrupts the combustion process, which can lead to cutting out and a loss of engine start.

Visteon DCU-102: repair or replace?
Having diagnosed their Ducato, Boxer, or Relay’s stored P0200 DTC, many owners opt to replace their defective DCU-102 with a brand-new one from Fiat, Peugeot or Citroen respectively. However, this isn’t the most effective course of action.

As Visteon DCU-102s are constantly in need of repair due to recurring internal malfunctions, there’s no guarantee a replacement won’t suffer the same fate. This can cause owners to fork out for an expensive replacement which only solves their symptoms temporarily.

Instead, we have a much longer-lasting solution – a comprehensive rebuild of your original ECU.

Our solution
We specialise in restoring full functionality to commonly-defective engine control modules just like the Visteon DCU-102. We utilise hardware-in-the-loop (HIL) testing rigs to examine ECUs under realistic operating conditions. This helps to pinpoint the root cause of failure, including hard-to-find and intermittent faults.

Our team of expert technicians will then rebuild your ECU with components of a higher standard than OEM. We do this to enhance the durability of your unit, which is why we proudly cover all rebuilds with an unlimited-mileage lifetime warranty – much longer than standard Visteon DCU-102 repair services. 

We’ll carry this out in just 2-3 working days and you won’t even need to recode the ECU back to your vehicle afterwards. Resolve your Fiat Ducato or Peugeot Boxer’s P0200 DTC for good, have your DCU-102 ECU remanufactured.
