Problem started about a week ago,
Drove about 30miles with no problems, then turned the car off for around 15-20 minutes, when i tried to start the car it wouldnt fire up, took the battery off & started fine & drove back again with no problems, ( been fine for about 3-4 days )
On Thursday i went to over take got to about 75mph & the car held back in a way & wouldnt accelerate any more just wanted to slow down in a way i had my foot on the brake ( Cruised back from work at 50mph all was fine, )
When out last night when i got to about 40mph i went to accelerate there was nothing all it wanted to do was slow down to the point i stopped, turned it off took the key out & fired it back up, got me to where i needed to go & back fine after that,

Now tonight i got where i needed to go which was about 5 miles away, on the way back about 1 mile from my home, started doing the same wouldnt accelerate, car would then drop revs, battery light would show then car would just stall, when trying the start it fires up then just drops revs Battery light shows & shuts down, took me 50 minutes to be 1 mile home :(

Any help would be highly appreciated

If the battery light shows and then it dies its low voltage. If its random I would say loose cable / terminal or bad earth.

If it was battery or alternator it would happen all the time.

i have plugged it into vagcom, but there are no codes, im guessing its because i took the battery off & left it like that over night,
I have just reconnected the battery & started it, Started fine, held revs as normal, didnt cut out, just drove 10 miles & everything seems fine, got home left it running for 10 mins all ok, turned it off & on a few time & idled fine,
More than likely it will be fine for the next 2-3 days then the problem will re-occur

Drove it over to my mate garage, used his code reader, came up with:

MAF ( low voltage )
Terminal 30 ( Low Voltage )
Secondary Air Valve ( This is because it been removed )
Rear Right Door Mechanism

When i went to leave started it up & revs dropped when i accelerated, disconnected the MAF & drove home fine, Looks to be the problem hopefully a new one will solve this
