308 T9 Diesel issue - P1199 and engine rattle on shut-off

Post by mvmc101 »

Hi guys, new here and I appreciate any comments regarding this one.

Bought a 16 plate 308 T9 2L BlueHDI, accident damaged but only minor, missing a bumper and needed the radpack replacing. Also had damage to the oil solenoid which I had to replace.

I'm getting the code P1199(I know the description of the error but there's no engine light on, there's also half a tank of diesel in it) along with a really unhealthy shudder when the car is switched off. I've got some diagnostic data here, unsure of what the oil pressure should be but it's showing as 0.31 Bar which seems low. I've not got an engine warning light or anything like it on the dash. It's had a fresh oil and filter fitted as well, hasn't been run on the road since the oil change and it had the issues prior to the oil change.

There's also an unhealthy surging/chugging when you put your foot on the accelerator like it's struggling to get back into its normal rhythm once you disturb its idle.

Any ideas would be much appreciated

I have heard of strange running issues after a frontal impact due to the catalytic convertor being knocked and breaking up internally. P1199 does not appear to relate to this, but maybe worth considering.
