2009 Defender 110 Puma 2.4 CSW Stornoway Grey

Loss of power

We have just taken delivery of our new Puma 110 2009 and it has been in the workshop ever since. On hot days here in the Mpumalanga we struggle to get up any decent hill. Revs won't go over 3000rpm and we end up in 3rd gear doing a max of 90kmh. Our local dealership are flummoxed. The offer a range of hopeless solutions from dark colour of vehicle, to weight of bull bar to the mounting of spot lights. Nothing they have done seems to fix the problem. We were wondering if anyone has had similar problems and what was done to fix them? A local mechanic (ex-Landy workshop manager) says that the intercooler is too small for African temperatures. He suggests that it be replaced but that invalidates our warrantee. Any thoughts?

Kind regards from South Africa

2008 Defender 110 Puma 2.4 SW Zermatt Silver

46C degrees, a fe hundred kg's of load in the Puma and 1.5 tonne of of-road trailer behind it. Not a problem. If it can handle the temps in the north of AUstralia I don't see it being any different.

However, I have worn through an intercooler hose and that did give the same effect you describe. I suspect there is either an air restriction or something is wrong with the turbo or MAF or MAP sensors and the engine is being starved of air or boost pressure. You could also have a stuffed intercooler. 110 2.4TDCi

boost pressure not registering in diagnostic (no fault codes at all have come up). Turbo already been replaced (no difference). Intercooler being looked into on Monday, just checking that a larger intercooler, fitted by LR does not invalidate warranty. will mention other points raised. cheers

Just an aside as I realise you said you have no fault codes.

If there's insufficient boost pressure the ECM logs a P0299 code. If it logs 3 in a row the MIL light comes on and you go in to limp mode until the fault is cleared. Things you learn when you blow an intercooler hose
