And you'll probably need a cotton bud or similar to reach down into the hole and remove the filter mesh itself.
Re: Power problem
Ahhh, sorry guys, thought there was another filter that I had missed!
I had already cleaned that one out when I changed the fuel filter. Took it out again anyway and was still brand spanking looking.
Looks like the pot has to come off again. Cant see anything else that has been disturbed
Thanks for the suggestions guys

Re: Power problem
Mine looked clean, try taking the Bongo for a blast without it fitted. I was convinced it was a TPS or gearbox problem.moots'r'us wrote:Ahhh, sorry guys, thought there was another filter that I had missed!![]()

Re: Power problem
OK, thought I would update
Drove the bongo with its problem as it really only affected the kickdown and I'm not that much of a speed freak. Made the decision a few weeks back that the bongo just wasn't big enough anymore for what we needed so bought a mk6 tranny and put the bongo in the site classifieds
Anyway, with regards to the power loss, took the pump apart again and found that I had put the cup that the springs push against in the wrong way around
So, swapped it round and bingo! All back to normal! That will teach me for not believing I could have done that and not taking it apart again sooner
Might be worth putting a note on the tech sheet that this can occur if being carried out by a numpty!!

Re: Power problem
The two basic inputs required by any auto trans are throttle position & road speed & from this the ECU (in the case of an electronically controlled transmission like the Bongo) can determine when & how to shift. If the engine is, like yours, down on power it will change gear late & downshift/kickdown all the time as you are having to give the engine more throttle to make the vehicle move at the same speed as you would normally. So for example you may drive on a light throttle up to 40mph with, lets say, 25% throttle opening normally (good engine power), to get the same speed with an engine down on power you will probably be at 50% + so the gearbox will late shift. Of course as soon as you feather the throttle, it upshifts as you have reduced the throttle opening. If you use even more throttle then it will downshift or kickdown, expecting the engine to then pull up to high revs, in this situation because the engine is not making its power that doesn't happen so you end up with loads of revs & no go.The thing that puzzles me is that it is affecting the gear changes. I would have thought that it would change up / stay up and just be underpowered rather than reving its nuts off in the lower gear?
This is a very common scenario & one we see quite a lot when car are either miss-diagnosed by garages or the power loss has been gradual (as in mass air flow meter issues) & the owner just doesn't become aware until the odd shifting makes him aware.

Jeezus moots - might also be worth putting on the tech sheet "don't attempt any mechanical job if you're a numpty" I'm thinking life threatening work like brakes/suspension/steering etc.moots'r'us wrote:OK, thought I would update![]()

Re: Power problem
You got further than me dude - I ended up doing my back in from bending over, before I'd even got one nut undone. 

Re: Power problem
Dont think I would do it again! Or, If I had to, I definitely would not fully remove the backplate to polish. Think I would just undo the and remove the left hand ( as you are looking at the pump in situ) bolt, slacken the right one and let it pivot down to get at the 'o'ring. It was the right hand bold that really gave the griefmikeonb4c wrote:You got further than me dude - I ended up doing my back in from bending over, before I'd even got one nut undone.


Mine was only leaking from the front one as well, if I had only changed that one I dont think the kettle would have had time to boil!
As I said, only took 5 minutes to get them out..... the rest is histo!

Re: Power problem
Very interesting tip that, about only removing one bolt - it was (just) one of the things that concerned me about the job.moots'r'us wrote:Dont think I would do it again!
