Thread: HELP - Engine failure in a 2008 Defender

I'm not sure if this will help Lachlan but I had a Td5 which in it's 4 th year and about 60K developed a fault with the TPO (Throttle potentiometer). This would allow the vehicle to tick over all day but any application of power resulted in missing and spluttering or the engine cutting right out.
Can't remember if it had any effect while changing gears but definitely similar in other ways to your prob.
Cheers.

should be a 300tdi and all cables

my first port of call would be looking to see if an intake / turbo hose is delaminating, collapsing or holed.

Don't know about the 300tdi bit, Transit engine I would have thought in 2008. Agree with the rest though.

Sounds similar to a egr fault maybe

I just read up on the EGR fault, and it does sound pretty similar to my problem.

Will look into it further and hopefully have some success!

Thanks,

Ahhh Poo! I was hoping for pics of ventilated blocks and broken conrods etc...








Is there a check engine lamp illuminated?

I'm assuming it is a TDCi, 2.4. The October issue of L R O International had this as part of an article on buying a 2nd hand TDCi. Hope it helps, Bob


The TDCi diesel engine is best described as brutal, there's so much torque. Originally fitted to the Defender in 2.4 litre form, a 2.2 litre version of the same engine powers current models, having been redesigned to comply with emissions rules. He quotes the 4X4 owner of Gumtree 4X4 in West Sussex as saying ' we have not yet had to change an engine, compared to some previous L R engines, there's no real problems at all' ".


"and ' Sometimes EGR valves are problematic, . Symptoms include loss of power, and lots of black exhaust smoke. The engine management light may come on, but not always. ' From Gumtree 4X4 again - ' Injectors are sometimes faulty, it may misfire & be running rough and warning lights may show on the dash display, but that depends how bad the problem is. It would have to be a long way out of parameters to show a warning light, but you would know anyway, as the engine would be running unbalanced. We've had to replace a couple of throttle potentiometers. On older engines, catalytic converters could get blocked - the internals crumble and break up, then get blown back to the silencer and block it up, then you have no power. Shake the catalytic converter, if it rattles budget for replacing the converter & silencer.'

Me too

Sounds like it could be the EGR issue, good luck getting it sorted
