hdi90 racing revs

Post by Badgerpoo »

I have a D9 HDI90 that won't idle properly. The revs will vary from 1k-1.5k seemingly at random. It does this in and out of gear, so when driving along off the throttle it will tend to try and surge forward. It does this even when warmed up.

Any ideas?

Could be a number of different things - faulty TPS springs to mind, but other causes are equally possible.

Try to find someone local with a PP2000 to diagnose it properly, it's likely to work out cheaper in the long run.
2002 HDi 2.2 Exec Estate, (2008-12) (wonderful)
2003 HDi 2.2 6-speed Exec Estate (2012-19) (also a gem)
2009 Citroen C5 2.0 HDi VTR+ Estate (godawful heap)
2008 BMW E91 330i touring (great fun - murdered by a reversing SUV)
2007 BMW E91 325i touring (slower smoother quieter)
