Hi all,
I was driving my 04 A2 1.4 petrol today,doing about 30 mph, and the car suddenly stalled with EPC ,engine and alternator light on. Then I attempted to restart the car and it will start with engine management light on. After that, I use my cheap diagnostic dongle to scan if there are any fault codes. And it pops out 5 fault codes. P0351,P0352,P0353, P0354 and P2101. Can anyone help. Could it be a pricey fault???


Thanks
qwerty
 
UPDATE: a few hours later, I start the car again when its cold and all fault codes has gone with no engine management light. The car was running on Tesco 99 originally and it has been running on V power for the last 400-500 miles.


Thx

Just wondering why you're running a 1.4 petrol on V Power and other High Octane fuels....isn't the price of the standard stuff enough for you lol? I believe it's only the more complex FSI that really needs the even more expensive stuff.
 
its a fault in the coil pack/packs depending on age of car---my money is that you have individual coil packs. i would also look at the plugs if they look old or dodgy replace at same time. cheers mike

P2101 code is throttle body so it could always be it just needs a clean--as this is a regular job on some 1.4 petrols

a2sumo: is it quite rare to have all 4 coil packs failure? The plugs has been replaced in the last service in Oct 2011, 5000 miles before. The throttle has been cleaned ~5000 miles before too. If the gunk has came back so early, is it possible there's another fault, or the 1.4 tends to collect gunk in the throttle?? :(

have you got one coil pack-large lump on end of head(engine not yours lol) or do you have individual coil packs(no plug leads)? if they are not audi coil packs it is possible that they have all suffered same fault.
cheers mike
 
i could remember that there is 4 piece of wire connectors on the head. Is it there are 2 versions for the 1.4 engines? Some got beautiful plastic cover guides and some got cables tied together? mines is the one with cable tied together.

thx

That wouldn't be the same garage that sold you the car would it?

Just seems strange to me that a 75ps 1.4 petrol engine should need high octane fuel...it certainly wasn't designed to be run on it.

Hope you get your car sorted soon.

Thxx A2Z,
Nah, I bought the car privately and that garage is an audi specialist in sheffield. But it does feels more lively with better fuel.
I hope the car can be sorted soon too, as i need to to travel to heathrow.

Hi qwerty from your discription you have the version with one coil unit and HT leads. So yes it is quite possible all spark plugs are having the same error due to common part in the ignition system. I would say get a new coil unit and see from there. If problem still occurs look at new leads and plugs.
Good luck mike
 
Hi Mike,
But mines got 4 independent plastic plugs, not ht leads.BBY engine code. But is it a serious problem to have faulty coils?


Thx
Fred
 
Nothing wrong with your choice of fuel if it feels better for you than 95ron then it feels better, but at the same time the fuel you have in your car wouldn't cause your issues. You'd have to run your car on Cola or iron brew to make it fail in said manner so i wouldn't give the fuel type a second thought.
