my 04, 2.0dti produces an intermittent turbo "kick up the bum "which can be a bit unnerving when creeping along in traffic and i suddenly surge ahead without any warning,this also occurs at any time,especially when accelerating .a mechanic suggested it could be a bit of turbo lag ??. diagnostic tests show nothing. so any ideas what might be causing it and also a remedy would be quite useful.
very many thanks in advance.
This sounds very similar to our 2004 dti. You can be pootling along in 2nd at less than 2000rpm and go to change gear when occasionally there's a fairly big slug of torque from the engine. I assumed that it was just a characteristic of the fairly agricultural engine. Let me know if you manage to fix it.
p.s. (My old Yamaha 600 used to do a similar thing at 7500rpm but that was more fun.........)
i have just had vauxhalls check this out via diagnostics and a road test......guess what........."there's nothing wrong with it mate".
why do problems never show themselves when there's a "man who knows all about motors"is driving the thing?
oh well, i shall just have to leave more room between me and the guy in front until i manage to sort it out.
Hi ,have you sorted the surging problem on your zafira ?, I have the same with mine and its driving me crazy, and is happening more and more. mainly in second gear, at about 20 mph and about 2500 rpm. It feels like the turbo goes on to full boost. can be dangerous when in traffic. I am a mechanic myself and do not think this is an air leak problem. also my car has no error codes present. i was wondering whether it could be a throttle position sensor problem or MAF sensor etc.
