Diesel Engine Cleaners Prior to MOT

Rickshaw · 17th April 2019, 16:37

One of my Diesel 75’s has just failed MOT - mainly due to ‘Emissions’ level. After a new Filter and a lot of heavy throttle a load of muck has been removed , Emissions improved a lot - so keeping fingers crossed. To be fair , it was SORN for 6 months and rarely turned over. Anyway , point is , it has been suggested to me that there are some specialists ( garages ?) which offer a service to put a Diesel through a series of processes / services to specifically optimise on emissions ( efficiency too ?). Does anyone know of organisations offering such service. I live near Guildford , Surrey but can , of course , travel - but if there is a ‘Home’ service that would be splendid. I have another Diesel and would like to have it treated before MOT.
All the best.

have you tried injector cleaner?
I had a very smelly tourer, used injector cleaner and the first journey was to its mot which it flew through on emissions and no more smell.

fill a new fuel filter with injector cleaner, run engine for 30 seconds, switch off and leave over night, next day drive it like you have stolen it. This was the advice I was given

Warm the engine fully, then drive to the MOT station using the gears to keep the engine speed at 4500 rpm, and ask for the emissions to be tested first.
