Glenlivet Posted April 13, 2016 Share Posted April 13, 2016 I've seen a few people mention this but never seen a definitive answer so here goes. Following hard acceleration or when slogging up a long hill in a low gear my 02 TD4 has a 5-10 second "breather", ie whilst it doesn't exactly slow down it stops responding to the throttle and stops working hard. It then picks up again and runs as normal. No warning lights on the dash or black smoke. I wondered about a partially blocked fuel filter. I've seen a similar fault on a RAV 4 diagnosed as svc sensors but don't know if this translates to other cars. The engine has done 107,000 miles and is otherwise spot on. No VCU problems and it's not gearbox related. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted April 14, 2016 Share Posted April 14, 2016 I've had a similar experience with a loose connector on the fuel filter I think it was (mechanic hadn't clicked it fully home after doing a filter change), but that wasn't load-related just random wobble related. Behaviour was the same though, it just felt like the throttle pedal had been disconnected. Quote Link to comment Share on other sites More sharing options...

It's not a big problem but would rather it didn't do it! Quote Link to comment Share on other sites More sharing options...
Mitax184 Posted May 6, 2016 Share Posted May 6, 2016 I had same kind of issue there is a small online filter that goes to turbo boost value worked a treat for me and solved my problem Quote Link to comment Share on other sites More sharing options...

Glenlivet Posted October 3, 2016 Author Share Posted October 3, 2016 Latest update. After full service with all filters changed including crankcase breather, no change. Diagnostics show a turbo fault, all the vacuum pipes changed, no change. Unplugged the MAF sensor, no change. Ok, it's a turbo fault. MOT due so plug the MAF sensor (still the original) back in for emissions test, lo and behold fault cured!!! I might yet change the MAF sensor but am loathe to bugger about with it in case it remembers about the turbo issue!! Quote Link to comment Share on other sites More sharing options...
