after finally getting my 2001 td4 auto to run again and get it mot,d and back on the road it has another issue now.
when i press the throttle it runs smooth to 4k rpm,then its like it hits a rev limiter...the revs drop then rise up and down with the throttle held in the same position.
hawkeye comes up with P0235...i clear the code but it comes back after a while...sometimes hawkeye says......boost pressure sensor short(open load or to ground).....another time hawkeye will say boost pressure sensor plausability with atmospheric pressure at idle.
i have changed the boost pressure sensor and checked the pipework as best i can......any ideas?
