Hi,

My 2015 3.0sdv6 has recently had an inlet manifold change and a throttle body change, both genuine parts but within 300 miles I have the P0234 code up again and the EML light is on, economy has also dropped down to 31 from 36 where it normally sits.this was all done with a specialist.

After the work was done I did get a P2251 code for the o2 sensor as soon as pulled away with my caravan but I cleared that and it appears to have stayed away.

I’m aware that the P0234 code stops the car from doing dpf regens so I’m keen to sort the issue, are there any other areas to check that could be causing the same codes? I’ve looked at o’reillys videos on YouTube and he has a few good pointers but just trying to cover all areas.

I’m trying to get back in with the specialist for them to have a look again but they’re a bit slow with responses. 2004 D3 HSE TDV6
