Citroen C4 Picasso/Grand Picasso, C5 and Dispatch starting problems – engine ECU fault.

Citroen C5, Dispatch, C4 Picasso / Grand Picasso

Citroen C5, Dispatch or C4 Picasso / Grand Picasso won’t start: frequently due to a fault with the Delphi DCM3.5 engine ECU.

 

This commonly failing engine management ECU is prone to internal component malfunction, which causes intermittent to permanent symptoms such as rough running, engine management light illumination, cutting out and ultimately complete non-start.

When diagnosing the problem via diagnostic scans you will find a host of fault codes including those for sensor supply, untimely de-energisation of the power relay and those for internal processor faults. The engine ECU may even fail to establish communications on a permanent basis.

 

When faced with Citroen Dispatch, C4 Picasso / Grand Picasso or C5 starting problems as described here, you may have been told that you need a new replacement engine ECU, which will also require coding.

 

We offer an enhanced solution for a fraction of the cost of buying new, without the need for expensive coding, and unlike the manufacture short one-year warranty we will provide an unlimited mile Lifetime Warranty for peace of mind.

 

Our in-house R&D team have identified a common defect in these engine ECU’s and have developed a rebuild solution using components that are higher rated than OE standard and that can be turned around within 1-2 working days.

Test and rebuild:

Using our bespoke Hardware-In-the-Loop testing rigs and experienced technical knowledge we can identify all internal ECU faults. Once all faults have been identified our technicians will rebuild the engine ECU and replace all common failing components with versions that are higher rated than standard. The ECU is then extensively re-tested to ensure that no faults remain. We only use OEM or above rated components, and unlike the manufacturer factory environment, our quality control is second to none.

 

Programming:

All original programming is retained – meaning that the ECU will be plug and play when you receive it back.

 

Quality:

Each rebuild must adhere to our strict Lifetime Warranty standards before it leaves our premises. Every step of the process is subject to strict quality control including testing, components and workmanship which is reflected in a defect rate no higher than 0.49% across all of our services.
