Throttle response limited in the rain!

Hi,
Hoping some genius can help me out. A while back I was sat at the traffic lights in neutral in my 53 plate mini one, lights went green, into first gear, accelerate and my revs refused to go any higher than 1500-2000, I thought I was in third, but I wasn't. I pulled over, turned off, confused and then started it up again, this time it pulled off fine. No warning lights came on. No faults in the subsequent weeks, until it rained again!!
It's now happened 5 or 6 times, always in the rain, sometimes multiple times on short journies. Always fixes itself when I stop & start the engine though. And I have never had any warning lights come on when it does happen. I'm starting to feel a sluggish response when it's not wet, but that may just be me.
Took it to my local garage (not BMW/mini), but it shows no faults and not even any stored faults.
I've read a thread on here suggesting it may be wiring damage but I can't ind any at all. Although that would make sense.
So can anyone help? I really begrudge taking it to my local dealer

You sure it's not just the traction control kicking in and shutting the power down until grip levels are increased. It does kick in rather too easily in my opinion.

Thank for the reply. Yeah I'm sure it's not the traction control, it feels like there's a limiter restricting me! It can happen when I'm driving along at cruising speed, the engine just breaks until the revs are low and then resists opening the throttle.

Hi ya

It sounds like it may be your throttle body playing up it sounds like your getting water in to the electrical connection.

When the garage ran a diagnostic on it did they use a hand held scanner, if so it will not pick up stored faults you need the bmw dis to go low level I think the auto logic can do it. Then you will find the fault.

When was the car last serviced ?

I did look at the Throttle Body wiring, but as it's pretty cramped in there I couldn't really see any.

I'll ask my garage, but he did specifically say there weren't any stored faults which by the sounds of what you're saying means they use the BMW dis?

If it is an electrical connection in the throttle body have you got any suggestions? I'm just a bit loathed to take it to the dealership as they'll most likely cost a fortune!

Hi ya

Personally I think I would disconnect the battery first (neg then positive) then disconnect the throttle body plug give it a clean with wd40. I would also make shore the ECM (engine control module) engines brain mounted in the battery tray on yours, make shore it's clean and dry and would disconnect the two plugs on it and make shore there's no corrosion on the pins or connectors then give then a very lights spray with wd40 reassemble them.
Never hurts to give the other plugs in the engine bay a spray with wd40
Then reconnect your battery poss then neg.

I would also have a good look round the throttle peddle to,
sometimes the potentiometers get full of crud and fluff they get cranky you may need to remove them from the car and clean them carefully.


Hope this helps

Thanks very much for the advice, I did all that over the weekend, however since it's not rained heavy I can't tell if it's worked!! Guess it's a waiting game now
