jim_69 Posted May 8, 2010 Author Report Posted May 8, 2010 just been reading a post on another site and someone has been having the same problem and its been suggested thats its a lhm (limp home mode) due to a poor connection in the engine wiring or a faulty ecu, anyone had a problem like this before?

paulh Posted May 8, 2010 Report Posted May 8, 2010 Happens to me quite often. Mines a taxi so ot does a lot of town mileage, I think the turbo pipes get clogged then it starts going into protection mode (limp home) as the turbo isn't boosting properly. A good thrash up the motorway usually clears it for a few days! Quote
