simon a Posted May 27, 2009 Share Posted May 27, 2009 My Td5 110 (1999) will only do 70 - 75mph (in 5th) when it reaches this speed there is a slight juddering - almost like a missfire on a petrol engine have replaced air filter - no change. any ideas?

mattltm Posted May 27, 2009 Share Posted May 27, 2009 Could be the in tank fuel pump. The same thing happened to mine a few months back. When you turn the ignition on, before you start the engine, you should hear a faint wining noise. That's the in tank pump. If you cant hear it or it's very loud then it may be dead/on its way out. Could also be oil in the injector loom. To check for that go into the seat box below the drivers seat and pull off the plug that is connected to the ecu (orange one i think). Check for signs of oil.

JST Posted May 27, 2009 Share Posted May 27, 2009 fuel pressure regulator, your age of vehicle had the problematic one as well which was superseded, you need the new gasket if it is at fault and up change to the later one. Quote Link to comment Share on other sites More sharing options...
Porny Posted May 27, 2009 Share Posted May 27, 2009 Other problem is that it could be hitting over boost.... Get a set of mole grips (or similar) and clamp them onto the turbo actuator an inch or so away from itts main body (on the none threaded section) - then try and make the arm extend towards the bulkhead. There should be some resistance, but it should move about 2cm or so. If it doesn't move you've found the problem... and it's usually easy to fix. Is very common on Td5's!!

crazyfarmerboy Posted May 27, 2009 Share Posted May 27, 2009 my dad's td5 did this, i took it to mansfield 4x4 and they cleared Faults on the ecu and it worked fine again Quote Link to comment Share on other sites More sharing options...

simon a Posted May 28, 2009 Author Share Posted May 28, 2009 Thanks - have noted that pump is noisy when you turn the ignition on. Also noticed a whirring noise from engine (something spinning) after engine is turned off. Continues for a while may be 30 seconds - any ideas?

Continues for a while may be 30 seconds - any ideas? a new whirring noise that has just started or is the vehicle new to you? if the latter - oil filter Quote Link to comment Share on other sites More sharing options...
Anderzander Posted May 28, 2009 Share Posted May 28, 2009 If I may I'd like to ask about this too.... What year did they fit the new regulator from? And are there any symptoms besides high speed juddering and/or leaking diesel? I want to get mine re-mapped in the near future and so want to sort any other issues before hand.

Continues for a while may be 30 seconds - any ideas? The centrifuge oil filter in the engine is one possible item. The fuel pump does not cut out immediately when you turn off the engine, so you can hear it running for awhile after you turn off the engine. You can 'feel' the centrifuge oil filter when you cut the engine and press the gear lever toward 3 and hold it there. (not into 3) Quote Link to comment Share on other sites More sharing options...

simon a Posted May 28, 2009 Author Share Posted May 28, 2009 Thanks for everybody's advice How do I get to the fuel pump - Have heard that you need to cut a hole in the rear floor but only seen measurements for a 90 - mines a 110 Thanks again Simon Quote Link to comment Share on other sites More sharing options...

So I measured 36cm from the galv door strip on the back edge of the tub and 28cm from the left side wheel arch. Mine is a 20cm x 20cm hole. You will have to cut through a strengthening beam. Once I had finished, I bolted a section of 1x1" angle across the beam and created a flap for the hole. Good luck! Quote Link to comment Share on other sites More sharing options...

landy andy. Posted May 28, 2009 Share Posted May 28, 2009 I would advise getting it plugged in on some ones computer before cutting holes in your Landy. Talk to Porny (as above) he's the man for Td5 diagnostics and tunning. Andy Quote Link to comment Share on other sites More sharing options...
