I apologise if this has been covered before or is a chronic problem that has been done to death over a number of threads, so if anyone can point me in their direction, i thank you, however, i do not know where to begin searching.
Effectively the problem is this, whenever I would approach a roundabout and obviously slow down

and then depress the accelerator the revs rise but then no response, no acceleration for a short period before it then starts to accelerate.
Any ideas, again apologies if already covered, if there is any further information anyone needs then dont hesitate to ask. I get the impression i`m being fobbed off by dealer so would appreciate some info from fellow V dubbers.
