The customer reported that he was driving along when all of the sudden the engine switched off and would not start. Diagnostics showed a blown 7.5 amp fuse and replacing this did not fix the problem and was advised that there is possible ECU damage.
We tested the ECU and found that the unit was in fact faulty. The customer authorised us to proceed with repairs and we replaced the main processor and the 8-way EEprom. Retesting the ECU proved that the unit was now fully functional and we returned it to our customer with a 12 month warranty and no need to program it – it was fully plug & play!
Other common faults associated with Mercedes Vito ECU’s include:
- Non starting
- No comunication with CDI
- Fuel pump shut off valve y73/75 code
- Burnt out from wiring conection failures
- EDC light always on
- Restricted to 3000rpm
- Fuses (7.5amp) keep blowing
- Won’t rev up at all
- Grey smoke
- Start Error ( Immobiliser Problem! )
We used new genuine OEM components when repairing this ECU to ensure that the rebuilt ECU meets & exceeds OE specifications.

Hi there, I jumped in to my van the other day, started it & smoke started to come from underneath the glovebox.. I immediately turned it off & had a look, from what I could see it was the ECU. I dropped it from the clips, checked the plugs & all wiring & everything seemed fine. I stupidly turned the ignition on again to see if it had been a slack connection or something & smoke then started to really come from it. I had the van in at Mercedes Commercial 4 days previous as it was restricted to “Limp home mode”. They fixed the problem & said the fault was the “Boost pressure transducer”. I have never had a problem with the ECU & have been driving the van in “limp home mode” for over 6 months, then all of a sudden Mercedes have the van in & low & behold my ECU burns out? Call me sceptical but find it bizarre. Anyway could you please send me your prices as I think it’s best to have the ECU checked to see what started the “melt down”. I don’t want to spend £200 on a replacement ECU & install for the same thing to happen to the replacement.
Sorry for the rather long email but I wanted to include all of the details leading up to the failure of the unit.
Best regards,
Steven

638 drove perfectly except for long cranking in the mornings. The turned into not hot starts, would start with es and drove faultlessly. Decided to sort out hp pump all fuel lines, filter, o rings, battery.
Now it starts perfectly but vibrates massively at idle and when turning. Drives fine once over 1200rpm and pulls normally.. EDC light is 0n constantly and glow plug light sometimes goes off as normal and sometimes comes back on.. you couldn’t make it up.
Does this sound like it could be an ECU issue?
I know injectors would be the obvious choice but they don’t look very old, this head is spotless and the edc and vibration had only come about since replacing parts and changing the battery after it wouldn’t charge up.
Also Changed engine mounts.
Cheers
Also how much do you charge to test and repair the ecu and what are the turnaround times?
