Hello all,
I'm looking for some advice, my 2004 TD5 defender has a slight issue i've been trying to pin down for a few weeks although the issue has been going for a while.
simply put, the engine starts, runs, drives etc. perfectly, I would never assume anything was wrong, it pulls well. it will be like this for weeks at a time, then all of a sudden I'll appear to gain what feels like 20hp! it will pull very noticeably better through all gears.
at first I though it was me, some days i'd have a heavier foot but recently i've been testing it.
when 'normal', flooring it from 50-60mph in 5th gear will take around 7 seconds. then when I can feel the extra power it will take 5 seconds. this test has been repeated many times with the same results.
today, pulling off hard in first (from idle) no chance of wheel spin, when i have the extra power the wheels will spin relatively easily.
I don't understand how something can be so intermittent. the only common denominator is I was pulling off a large roundabout in 3rd, then i could feel it, a sudden surge of power and there it was, then for the rest of the journey i had the extra power. I stopped, turned off the engine for 2 mins, continued, still with the extra power. then after 4-5mins, pulling off a roundabout in 3rd again, I felt the power drop off and the rest of the journey was back to 'normal'.
I would say the difference between 'normal' and extra power is as night and day as stock vs stage 1 remap.
the vehicle has a stage 1 remap, with EGR delete and no centre box, it still has a CAT.
things i've checked so far:
clutch switch
ECU for oil, nothing noteworthy.
various connections in engine bay.
next step if cleaning sensors and finding someone with a namocom or similar.
any ideas?
many thanks,
Callum
