Hi all,
Having problems with my A2 1.4 petrol and thought I would ask for some opinions. If people would be so kind!
For a background - Due to an intermmitent EPC light on a previous visit my garage already told me he had erased codes for EGR valve and inlet manifold pressure sensor but the car ran fine and EPC light has only come back once or twice briefly in the last 6 months.
Forward to October:- Was driving home and my brakes pedal went all spongey and ineffective!! It righted itself so I kept an eye. A few journeys later it did it again and the ABS light has popped up! Did this a few times over two weeks when finally as I was nearing home I could hear an awful scrape on turning? (Unsure if this is related to the ABS fault). I decided to park up and have only just got around to looking at the car (had a house move)
The abs fault bothers me most as it is clearly a danger to drive.
Car battery was flat so I charged it up and pulled off the following codes using the cheap chinese U281 VAG reader: (so some codes may well relate to the battery voltage)
Engine:-
16555 P0171 Fuel Trim - System Lean (Bank 1)
16786 P0402 EGR Flow excessive
17566 Manifold pressure sensor - Implausible signal
A/T (Couldn't link) What is A/T? - Does it mean automatic transmission?? (hence why it wouldn't link as mine is manual!)
SRS:-
00532 P1746 - Low voltage
ABS:-
00810 - Sensor 1/2 For brake pressure : No or incorrect basic setting/adaptation.
I'm no mechanic but wanted to ask opinions if these fault codes (especially the ABS) relate to my symptoms. My initial thought was abs pump? but then the scraping sound when I last drove the car made me think - what was that - perhaps a caliper or disc issue? or even a stone trapped (I can't yet drive car to check for a stone as tyre is flat and won't reinflate...) Or possibly two issues, unrelated?
If there are any A2 brainiacs out there who could offer an opinion on all codes, I would be much obliged.
Thanks guys
