2002 TD5 110. 93K, VGC
First thing in the morning - it's tugging at the leash.
Couple of miles up the road, it's less enthusiastic.
Not stuttering, just - not pulling that well.
Uphill, 55mph, start to lose speed slightly - drop to 4th - and it's still lost a bit more, it might maintain, say, 46-48, but struggling to accelerate at all.
Sometimes, the 'reluctance' starts to manifest just after I've done an overtake - you know, the 40-55 range where many people just stick at 40 on a de-restricted country road. I nip past, but notice that, going from 4th to 5th, it's a bit flat, doesn't really pick up.
In fact, I'd say that the engine sounds slightly laboured
Oh - I tried something today - turned engine off at traffic lights (about 4 mins). When started, it seemed to pull ok for a little way, then 'reluctance' returned after about half a mile.
Thoughts:
fuel (filter, mesh on pump in tank, other?) - pump not noisy.
air: hose delaminating? (which - intercooler to turbo?)
Other: - sensors? - EGR (should that affect it under load?)?
ONe last thing - it does have a tiny, tiny diesel leak (not enough to drip on floor) - there's pressure regulator (something like that) at the back of the block, right hand side - common fault I'm told. It was little enough that it's just passed MOT with it.
Finally,my previous 2002 90 did something similar, though not as pronounced and less often; some days it just went well, others less so. The last time I saw hurtling off, driven by a couple of hoodies, it seemed to be going very well...
My question really is about how to go about diagnosis. I don't want to just change parts at random, so I suppose I'm after a methodical approach to eliminating possible causes one by one.
Anyone else had something similar?
cheers
