Hi guys I'm ash and I would have liked to introduce myself before jumping in for help

but hay ho.. I'm 24 have my own company and race the British 2 stroke mx
Iv just bought a transit connect 1.8 CDTI on an 06 plate for £1280..
It was a gamble as I thought it must me cheap for a reason..
It seemed to go week feel well no clutch slip gearbox is slick BUT iv had a few Limp mode experiences.. I'm guessing it may all be linked to the very poor starting no matter what the weather or engine hot/cold..
These codes it obtained via the digital dash clocks
p156
p202
p300
p400
All in all is like to think i got a bargain but time will tell..
This is the culprit
thanks in advance guys!
