Welcome to the club

Welcome to the Forum, Wayne...

Did they not plug her in for fault codes? If YES then what were they?

TBH, save youself some money and get under the bonnet - Working mainly around the engine block - Find a Sensor and remove it to clean and replace !!

First thing that pops into mind is the throttle body. A dirty one can cause patchy/stuttered performance.. Gav's initial advice seems to be the winner...

Thats perfectly true, Daz... I taught Gav Well :rolleyes:

Hehe I only diagnosed it that way as my Passat used to drag its ass everywhere until it was cleaned ^^ I think every petrol-head has had that problem at least once :P

cheers guys i cant mind the name of that valve its something like dessus it just infront of the air vent valve i dont know mutch about bmw engine to many things on air system to go wrong.How do i go about cleaning throttle body. :unsure:

By far the best way to clean the Throttle Body is to remove it and soak it in either, thinners or petrol, then after a short while get in there with some intricacy lol...

Don't forget to re-grease the outer moving parts afterwards !!!

Try to find the name of that valve, I think a well known commedian may have examined it :unsure:

Talking of cleaning the throttle body Dabz, I cleaned mine the other day and there is a plastic 'butterfly sensor' screwed onto the side with two cross-head screws holding it onto the butterfly pivot. I'm afraid I got it too wet and screwed it up. Are they known for failing after a clean dua know?

Hopefully your info can help out EVERYONE on this thread, not just me ^^ hehe

Not that I am aware of Daz... How did it fail on you?

Tell me you didn't have the keys in while you cleaned yours :huh:...

Like I mentioned, best way is to take it off... Easier to clean AND safer Lol

Sorry matey, I worded it wrong.

I "Fear" it may fail when I put it all together again because I got it soo wet when cleaning it. It hasn't actually failed :) (I hope...)

Give it a go mate ! Got to be worth a couple of hours to know (peace of mind) ...
