Vw golf stalls at lights and roundabouts

hello ive got a problem my golf 1.4 16v petrol year 2000when it reaches 2700 revs it cuts out and restarts like I basicly turned the ignition off and on again althought no other elictrical part of the car goes off stationary or driving it makes no differenceif im driveing along at 2700 revs just before it cuts out and drop a gear it lets me go past 2700 thus i can wind my way throught the gears past 3000 revs
as soon as i slow down around 3000-2700 revs it cuts bk to doing the same on off on offthe radio-lights-windscreen wipers don't slow/shut off while this occurs and nor does anything elseoccasional when this random cutting out /restarting happens the oil light-pump stops working /light comes on and the rev counter stops working so i have to pull over and restart the car.its just passed a MOT with no faults and wonderfully for me the fault didn't happen that day ....ive changes plugs wires checked fuel pump-air pressure and i cant find anything
pls could you give me some hints etc of what might be the issue

could be the brake servo pipe is leaking air and causing your car to stall, hence the battery light comes on.

check the vacuum pipe from the manifold to the brake servo can.......if loose it will draw air in and stall as above.....

You need to check the cable the runs from the gas pedal to the engine, it might be rusty and need some drops of penetrating oil at the point it meets with the engine accelerator valve.

hi i have the same problem.but i cat find what to do.iff u eill find out please le me know.07853592087

I believe it is the computer sensing the exhaust components and that is the reason for the drop. My truck does the same thing, so that is my answer.

clean the throttle body out only four bolts hold it on,you will need to reset basic setting afterwards,quite a common fault

Heres the wiring diagram Good luck hope it helps.

i would start by cleaning out the throttle body. they collect soot and not have to be a lot either for it to mess up the idle speed, i had trhis on mine soon as i dipped the clutch to slow down the rpm dropped to about 400 to stall, i cleaned throttle body out ( taking air intake off and wipe round inside and the butterfly will be enough) and now it idles and the rpm dont drop below 900

everywhere i look loads of gti's are cuttin out. mine did.it would cut out for no reason and the dashboard lights would come on. changed dizzy n no joy so i found out that if i replaced my relay fuse(number 31 on ure fuses) it stopped cutting out. i got my part from vw dealer and costs £13! its never ever cut out since and that was at least 6 months ago. hope this helps.
