Hi - new on here so please be kind!

Car - 316i Touring 2002 1.8 16v N42 Valvetronic Engine 70K miles

I have noticed recently that sometimes/intermittently when i go to pull away, or after letting the revs drop,that the car is extremely reluctant to pull away and there seems to be a loss of power/ throttle response. There just seems to be little or no throttle response for 5-10 secsthe car lurches and then decides it wants to go - This is becoming rather a worry when pulling out at busy junctions and/or roundabouts especially with kids in the car - will the car do it or not!!

So far i have had the Softwear wipped and latest version uploaded and MAF sensor changed, but neither seem to have cured the problem.

Whats also worring, is that there are no engine management lights on and no codes stored - rather worrying considering the fault.

Has anyone any ideas, or experienced a similar problem?

Were the fault codes read using a BMW specific scanner nick jones?

And has the engine induction system been checked over air leaks/split hoses, split breather pipes e.t.c?

Sounds very similar to other issues Ive been hearing about.

I would search on here for underpowered, loss of power, etc as I have a thread about 5 miles long about my experience.

It could be a duff MAF.

Also could be bad scanner that didnt throw up BMW specific codes. Which it wouldnt understand if it was a universal.

The Problem of dying has been fixed!!!!

After numerious returns to a very helpful independant BMW garage, the owner took it upon himself - as a personal challenge to sort the problem.

finally, after contacting loads of his BMW mates, mechanics and diagnostic software people, he came up with the answer. a simple remedy called an 'adaption test' which involved driving car in 3rd gear @ 35mph for 10mins and then doing something with his box of tricks -Basically resets the ecu/valvetronic which was out of sync.

Noprobs since this was carried out - Thanks very much Dave at EDEN MOTORS YEOVIL

I see.. so whome and where would i go to talk about this thing then coz im interested as i took my car to the dealers and they ran diagnostics on it and found nothing and had a root around and a test drive and didnt notice anything.. but its deffinately there still and annoying the crap out of me.. they say my timing chain might have slipped but that would require 2 hours labour just to diagnose the problem!
