Sorry about the delay in responding to you teenmal - we've been away Bongo-ing for several days without any access to internet. You are probably right in what you say. But the scavenger fan relay is definitely faulty and I'll replace that first. I don't have a warning light on the dash but when I re...

Thanks Geoff! I really appreciate your time and trouble in responding to my query. Those six relays have moved to just behind the front panel alongside the radiator on the later model, but I spotted them easily enough when I knew what I was looking for. And to my considerable relief the scavenger re...

Ah! Thank you Geoff. That's a great help. I'll get back under the bonnet today and see if I can sort it out. I'll let you know.

Okay, I give up! Can anyone tell me where I find the scavenger fan relay on my 2000 2.5 Diesel please? It's no longer working - so I can't listen for a click. As the scavenger sensor is good and the wiring to and from the sensor is sound (and the fuse hasn't blown) I think the problem must be a defe...

Just an update on this problem and a Thank you to all who responded. I've subsequently made sense of the fault codes. I hadn't realised that the 4-number codes give a long flash to denote the start of each digit in the code, hence I missed the zeros! When it dawned on me, I realised I had a pesky EG...

And thanks Geoff. Yes, the ECU I'm dealing with is rather different, though it has occurred to me that by studying the earlier diagrams I can probably get a much better idea of how Mazda wired the control systems than I have so far! Thank you for all your work on these and I'll see what I can learn ...

Thanks for your replies. I'm assuming the problem, or at least a part of it, is a faulty scavenging system and having the engine cover open is easing this. As Rita notes, this ties in with the codes. I've checked the resistances across the engine bay temperature sensor and they are good, as is the 5...

I've recently been crazy enough to take on a Bongo which has been VOR for several years following an engine cutting out problem which gradually grew in frequency until it was impractical to drive. It's a 2.5td AFT 4WD made in November 1999. It starts without problem, but after say 8 minutes of idlin...
