Hi guys, not sure if this is in the right section. I bought a 150 cdti 05 reg about 4 weeks ago. First 2 weeks were fine, no faults. Then as I was driving along the M1 one day, my engine light in tacho lit up and car went into limp mode, pulled over at next stop - refired engine and problem was gone. Then a few miles later my exhaust emissions light lit up and it felt like it went into limp mode again. This time a restart of the engine didnt make the emissions light go away, no matter how many times I restarted the engine. I left the car to sit for a few days and the next time I fired it up the light was gone and power restored.. only for the same thing (emissions light + loss of power) to happen a few miles later.
I took the car to a mate with a plug in jobby (yep, thats how clued up I am with cars lol) and he got fault code 1125 come up. He says it could be a massive job to pinpoint and fix the problem.
I was just wondering if anyone has had experience with this kind of problem and whether there could be a simple fix?
