I had a split manifold to intercooler pipe now replaced all hoses
However, its now going into limp mode straight away as hit 2K revs with fault codes P 244a 96, Low DPF pressure
I did a forced regeneration of DPF but it literally goes into limp mode and when on motorway at speed or when engine revs uphill above 2000rpm after about a minuite of driving.

If the car is driven below 2000rpm no warning or issues
I checked the 2 small rubber pipes underneath the car they are fine no splits or damage.
.
When engine is switched off after about a minuite Resticted Sign disappears

I have noticed that there is a bit of damage on the intercooler fins and wondered if there is a small air leak this could cause my problem

Thanks
