Hi all,

I recently ran a ODB II on my car and it’s came up a couple of fault codes, as follows:

P20EE

Nitrogen oxide (NOx) sensor, catalyst, bank 1 - efficiency below threshold

Status: Pending

Engine control unit

P003D(75)

Intake camshaft profile control A, bank 1 - stuck on

Status: Test failed, Pending, Test failed since last DTC clear, Test not completed during this operation cycle

And to add to this, it’s regening every 100 miles and recently went into limp mode with a coil light on the dash, but it’s running normally now. Has anyone had these faults? And if so, what’s involved and the cost of these fixes?

Thanks in advance

Regen every 100 miles isn’t normal, unless your trips are all short. Do you do longer journeys say an hour on the motorway?

If not try this first.

DTC clear isn’t helpful as it can hide/delete some of the required info.

I’d recommend visiting a garage where they fully understand the DPF and all its related system and faults. Most garages definitely don’t.

Baz Merideth and O’rileys autos are 2 YouTube channels worth looking at. One of these may be local to you

Will it do a full regen if there is an error on the system?

I’m in Edinburgh most of my journeys are town driving with stop start traffic ( should have got a petrol , wife once a week goes to Costco which is about 20 mins each way on bypass

@Ramsay7 Worth telling if a 1.6 or 2.0 TDI and saying how many miles on it now. http://autohausedinburgh.co.uk
