Hello everyone,
I am a taxi driver and have a 2014 Vito, I have joined the forum as I am desperate for any advice or similar experiences relating to a suspected fuel delivery problem.
The vehicle has 130,000 miles on the clock and about a year ago started to lurch and judder intermittently when accelerating under load.
Covid has hit my industry hard in the year since and I have so far spent approximately £4,000 trying to get this issue resolved with no success.
Please if anyone has any advice or suggestions any help would be very much appreciated. I've described the issue below and also listed all the steps that have been taken already to try and resolve the problem.
Issue Description
When accelerator pressed while under load, eg going uphill the power to the engine seems to cut out intermittently. This results in the loss of all acceleration for a moment, while foot is still down, before the power kicking back in. As a result of this issue the issue lurches and kangaroos forwards and can give the impression to passengers that I am driving dangerously.
Also when idling in neutral the vehicles shakes more than usual and the engine noise is erratic.
I think it is a fuel delivery problem, but the engine management light does not display so no one seems to be able to diagnose the issue.
Steps to try and fix
I've taken the vehicle to multiple garages, a Mercedez specialist, taxi specialist, diesel engine specialist and mobile mechanics.
After each of these steps there is a brief improvement in the issue, but within 48 hours the issue starts again.
- Mass airflow sensor replaced x2
- EGR replaced
- Replaced air filter
- Replaced oil filter
- DPF cleaned
- Catalytic convertor cleaned
Each time I visit a garage they investigate, think they have identified the fault, then repair and I pay for the labour, parts and VAT only to find the issue is still there within a few days.
Any and all suggestions would be really helpful.
Thanks
James
