Hello, Apologies for not replying sooner - I've been snowed in for six weeks and couldn't do any proper testing! So, here's some Scottish landscape, enhanced with my Defender, which now has 100 miles behind it on new capacitors! Obviously, I wouldn't say this within earshot of my ECU, but the...

Yep - if that's really fixed it, then it's very satisfying :) The capacitors required are: 3300uF, 40V and 1000uF, 100V. Capacitors tend to fail, in my experience, because they're one of the few solid-state components which degrade with age. The mode of operation tends to accelerate that in...

Another update... Despite a lot of searching, I couldn't find PEH169 capacitors for sale anywhere...and to be honest, they'd be such old stock, I wouldn't trust the dielectric not to have dried out by now, anyway. On the basis that a capacitor is a capacitor is a capacitor (except when they...

Hi Brown, thanks very much for your input - all very helpful and encouraging in terms of the symptoms matching the cause I'm going for. The Foxwell code reader I've got is nowhere near clever enough to recode ECUs, injectors or 10AS modules - if it comes to that, I'll have to take...

Hi Raywin, thanks for that - the thread is certainly helpful. A long time ago, I had the whole melting handbrake cable thing happen to me and changed all my earth straps and added an earth cable direct from the battery to one of the ECU mounting bolts. Although I replaced the chassis and...

...and, indeed, after a little bit more reading, I found this, which says (amongst other things) : "[The] TD5 2.5 ECU is a common failure for...the...Defender, failure can cause the engine to cut out intermittently, normally after leaving the vehicle for a few minutes the engine will re-start...

Hi Tim, thanks very much for all that info - very helpful! Very much clutching at straws, I decided to replace the CKS sensor connector and bypass the cables to it with a new, screened cable, going direct to the ECU. To my delight, the engine started a revved without stalling...to my utter...

Another update: I took the ECU connector out again and cleaned it with contact cleaner, but no change. To try and rule out a wiring issue between the CKS sensor and the ECU, I measured the resistance across the CKS sensor from the red ECU connector. The resistance across the old sensor is 1.2kΩ...

Thanks for that - I think that's the next sensible move. This is quite an interesting thread on what sounds like the exact symptoms I'm getting...

Hello, a bit of an update on this: I fitted a new MAP sensor - this seems to have fixed the intermittent 0kg/hr airflow, but didn't improve the non-starting. I've just fitted a new CKS sensor - this is a pain to fit, but there are worse jobs to do on a Defender. After a bit of a...

Hello, thanks for your thoughts lightning - there are certainly a lot of error codes here, but most of it can be ignored from what I've read. Most of the DTC's active and logged on my ECU are for additional systems I've not got, so the only ones I'm worried about are: DTC --- Air flow...

Hello again, Mid-Winter Seasonal Gift-Giver (aka Father Christmas) brought me a Foxwell NT510, which was good of him, so I've been able to do some ECU-based diagnosis on this problem - I'd be very grateful if anybody who understands these things had the time to look over the extensive list of...

Hi Tim, that wealth of info is incredibly helpful - thanks very much indeed! My 110 is an X-reg (00/01) with a 1Axxxxxx chassis number, so an earlier model, I think. I haven't looked into the options, yet, regarding replacement of the ECU, but almost certainly a used/reconditioned unit...

Hello, I've not started diagnosing this properly yet, but it's looking possible that the ECU in my Td5 110 has packed up. Can anybody explain the process of getting a replacement and coding/mapping/registering it to my vehicle, please? I see on ebay, they tend to be sold with the green...

Nope, not as far as I know - it's entirely up to you and how much value you put on the shininess of your fixings :) The benefits and down-sides are exactly as you say (again, afaik)...

Excellent! Well done on getting started. Here's how I did mine - maybe there's something here you might find helpful. I look forward to seeing how it goes :)

I rebuilt my 110 and replaced pretty much every nut and bolt for stainless. I got most of what I used from YRM, who sell stainless kits, which is handy. Anything where the bolt tension was critical used A4-80, which has a tensile strength of 800MPa, the same as 8.8 rated zinc-coated bolts...

Because I didn't have any problems before I took the hub off, I just put it back on un-molested. All I did was check the bearings turned apparently smoothly and packed in a bit more grease... I've ordered a new set of bearings, but I didn't see a spacer in the kit I ordered - a problem, do you...

Thanks for clarifying that - I'm not an expert by any means - any shared knowledge is very gratefully taken on-board :) I've always imagined any pre-loaded bearing will slacken off slightly with initial use and then continue to reduce slowly over time, but is that the case? I've tightened the...

Ah, right - sorry - didn't realise it was a 300Tdi - who would have thought that the swivel pre-load would be different?! Do you mean the swivel-ball seal? Why can't you check the pre-load with that fitted? It must add a bit of drag to the ball, but not a massive amount, I wouldn't have...
