    Engine management light came on for 2 minutes then went off. Audi A1 14th Mar 17 at 8:59 PM
    Hello,

    I have a 13 plate Audi A1, 1.6 diesel, 19,500 miles.

    On Friday morning (it is now following Tuesday evening), I was driving to work and my car cut out whilst turning a corner. It struggled to restart but eventually did. I kept an eye over the weekend and it seemed fine.

    Monday evening driving home from work, the engine management light started flashing 2 minutes from home. I stopped at home, locked and restarted the car and it didn't come back on. After reading some posts on the Internet regarding short trips and diesels, I took it on the motorway for 20 mins at 60-70mph and filled my almost empty tank with the more premium diesel.

    The light hasn't come back on since yesterday after work. Because the light is no longer on, does this mean it has sorted itself out? I am just worried that I could be causing more damage to my car but don't want to pay the 50 to have it scanned if it's probably ok!

    Thank you for your advice! I'm a bit of a novice with this subject.

    Buy yourself a code reader or get a garage to check the codes.

    I have contacted audi and they were going to charge me 120 to check and then I rang halfords and they said 50. Do local garages do it for free? Or at least cheaper?!

    I may be telling you something daft but my 2.0d A3 had a fault where it just cut out at low speeds. No warning and no stalling - it would just die. I took it to Audi under warranty. They said it was a faulty ignition switch and replaced it. It never happened again. If it's going to cut out it's best to get the fault codes read just in case. We have a code reader which then involves a lot of googling but then if it's an issue it needs to go to a garage anyway. I had my current car checked at a local garage for 25 - BMW wanted in excess of 90 just to diagnose.

    I use a local performance garage who uses the same parts as main dealers but his labour costs are way lower. He was 60 less than BMW to check my engine fault. Probably a third cheaper for the work as well.

    Thank you, I'm going to try and get in at the weekend as I can't stop thinking about it doing it again! I bought an audi because I thought they were reliable... I'm starting to think otherwise

    Your mileage seems way too low for a diesel. Does it get long runs to clear the DPF?

    Any diesel, no matter what make, can suffer with lots of short runs.

    4yo car, <20k miles... DEFINITELY going to have DPF problems sooner or later, unless you've only recently bought it, and are stacking the miles on much faster than the previous keeper.

    I wouldn't worry about it. Audi cars are one of the most reliable car manufacturers out there (up there with the likes of Mercedes, BMW, Volkswagen).

    If the light has gone off it means the ECU does not detect any problems. Don't sweat over it.

    Unfortunately thats not quite right. Anyone with a code reader will tell you cars have actual faults, stored faults (it will show how many miles and how many restarts since fault occurred) and also pending faults.

    Try an online Audi forum, someone local will offer to read your codes. I have PCM scan software that is excellent, well worth the money.

    Agreed. I've currently got 3. All petrol though. I wouldn't have a diesel and I do over 20k miles a year. I have to say reliability has been great.

    The light has come on because the engine management system detected a fault, the fault could be absolutely anything with the system and not necessarily related to the diesel particulate filter (DPF).

    The DPF will have it's own separate warning light and should give you a fair warning that you need to regenerate it, if it is ignored it will log the fault as more serious, put more warning lights on and eventually restrict engine performance.

    The fact that the light went out on its own is good, it means that the fault occurred maybe once and after so many engine starting/running cycles it hasn't occurred again. A fault code should be still stored in the ECU and with the correct diagnosis equipment such as VCDS it should record the fault frequency/time and some data with it - engine/road speed, vehicle voltage etc - this will help in finding the cause.

    You say that it happened when steering the car, the A1 has a steering system that is electrically powered and it can consume high currents up to 60 amps, this can place a momentary load on the battery which after 4 years it may not be at it's best, which could cause voltage drops to the sensors on the engine.

    I bought the car a year ago with only 13,000 miles on it. I don't drive it enough at all and wish the garage dealer had warned me of this when I bought it because I didn't know this was an issue!! Thinking about trading it in for a petrol, just don't want to lose money on it !

    I do sometimes have a different light come on for the DPF and try to give it a good run when it comes on. Think I might seriously consider swapping it. Love my car though!!

    Make sure you have enough diesel in the tank in future.

    It wasn't on red? Does it need to have more than that in even? I can make sure it is topped up if that will help...
