Hi all

 

Took my car (2.0 TDI Scout, 2011, 104,000 miles) for a long run at the weekend, mainly motorway. Got a bit low on fuel, computer said range 40 miles or so by the time I got home, so I filled up today on the nursery run. (Short journey, about 25 miles range by the time I got there). About halfway into the drive (stop start, engine off and on) the check engine light came on. engine ran fine, no problems, so I kept going thinking it might be due to low fuel. Fuelled up, but engine light still on and after a couple of miles of driving. I read the fault codes when I got home and got P2453, P25454, relating to DPF differential pressure sensor. I cleared the codes, but the engine light still seems to be on - I haven't driven it again yet though.

 

I was wondering, is it possible for low fuel (possibly even a bit of crap at the bottom of my fuel tank) to cause this fault code? Or do I have a DPF pressure sensor or DPF fault too? Seems a bit strange it should pop on after a long motorway run, when usually my driving is a mix of town, A road, motorway... Normally I use proper garage diesel, but today had to put a bit in from Tesco - but the light came on before I got to Tesco petrol station!

 

Thanks for any thoughts.

Locate and visually inspect the pressure sensor, they've been known to melt!

Ha! Hadn't seen that on here!

 

I've checked, and it's still there, and unmelted...
