hi mate

you ve got ans overfueling effect and the reazon is faulty injectors giving poor injection.

132k is more than 211k kms ---- it is the time for injectors test.

...would that not bring on engine mangement light...

Not necessarily (yet).

When new, or replaced, each of the injectors' characteristics are measured and programmed into the ECU as a compensating factor.

From then on, the ECU knows exactly how long each injector should be "opened" in order to get an equal distribution of fuel into the cylinders.

Over time, the injectors suffer inevitable wear, but the ECU doesn't know how much and still operates with the original data.

Wear of the injectors is caused by the thousands of liters of fuel that are blasted through them at 2000 bar, and impurities in the fuel.

Some injectors wear out quicker than others, leading to rough engine running, higher fuel consumption, the EGR and DPF clogging, and/or the catalyst giving the ghost.

That would bring up the engine management light and an MOT fail.

Testing the injectors will show if they are still within spec, or should be replaced with new or refurbished ones.

They are expensive, and their life should therefore be lengthened by proper maintenance.

That means good quality fuel and a fuel filter in excellent condition.

As mentioned by Igor, I'd say get your injectors checked.

Most common rail fuel injectors tend to need replacing by 100k.
