Electrical/Power loss issue...

[E2FAS]

My S3 has recently giving me a spot of bother and hoping someone will know what it might be.

• Driving as usual, and my battery warning light comes on.
• I carry on driving to get home and then after a minute or two, my ABS and traction lights appear.
• Also my head unit / sat nav has switced off and died down.
• Lights/all electrics are either dead or very weak.

I then try to get home quicker and tried to put my foot down a little (not thrashing) but it started holding back strongly, like it was being restricted of airflow (sudden hicups).

This has happened once before on the motorway about 2 months ago, but that time the battery warning light never came on and once I got it towed home it started without any issue - I was told it had a faulty MAF sensor.

Could this be a battery/alternator problem as thats what I think
or a MAF sensor problem..?

Any advice/help would be very much appreciated..

Almost certain it will be the alternator, check connections first

Yeah sound very similar.

This happened to me last year the night before Nurburgring. Lucky a mate had one at his yard.

I have a brand new refub'd one at home PM me if you need one.

Ok cool will get in touch once I got some funds + time, I am looking to carry out a full service and include the alternator change in that but waiting for payday and work is too ****** hectic lol - cheers though.
