keany Posted October 26, 2011 Share Posted October 26, 2011 Hi everybody, I have a 2005 TD5 Defender. Been having a problem on and off for a while....My Land Rover occasionaly has no power when pulling away in first (sometimes my right foot is flat on the floor), and stalls. This happens usually, but not always, when pulling away up an incline. Has just had full service and still have the issue - any suggestions?? Thanks!

101sean Posted October 26, 2011 Share Posted October 26, 2011 Could be several things. Get it plugged in and faults and live readings read. Quote Link to comment Share on other sites More sharing options...
Dorset Cocker Posted October 27, 2011 Share Posted October 27, 2011 Sounds like how our TD5 Disco was lately and it was all due to the Mass Airflow Meter, we had it put on a diagnostic computer about 2 months ago but it never picked it up then, which I believe does happen.

Tanuki Posted October 27, 2011 Share Posted October 27, 2011 My 2001 Defender TD5 had a similar issue: turned out to be the turbocharger wastegate was sticky. Sometimes it would stick open - resulting in no boost at low revs and an engine without enough torque to pull the skin off a bowl of custard; other times it would stick closed causing the engine to overboost with anything more than a whiff of throttle at around 1500RPM which then triggered "limp-home" mode on the ECU and gave sloth-on-valium can't-exceed-70MPH performance. Lots of manual wiggling of the wastegate actuator accompanied by applications of molybdenum-sulphite powder to the bearing sorted the problem. DO NOT use oil-based lubricants on the wastegate-arm bearing: the heat will cremate the oil to a sticky mess and make the problem much, much worse!

C18RCH Posted October 28, 2011 Share Posted October 28, 2011 Sounds like a turbo related problem to me. Check all the turbo pipes aren't loose or split and as above could be the waste gate. Quote Link to comment Share on other sites More sharing options...

Hi, Sorry to be complete div but do you apply the lubricant to the linkage at turbo end or to the rod going into the actuator housing? Should I be able to pull the rod back and forwards from the housing - at the moment it doesn't budge at all. Thanks for your help Quote Link to comment Share on other sites More sharing options...
keany Posted November 3, 2011 Author Share Posted November 3, 2011 Sorted - it was indeed the wastegate. I did as you said and it freed up. thanks very much for your help! Quote Link to comment Share on other sites More sharing options...
