Ds3 Dsport 1.6 engine management system faulty warning

[Masonabi]

I have a 2010 ds3 dsport 1.6 the engine light has come on and a warning flashes up on the screen saying "engine management system faulty" my other half changed the spark plugs and it turned of for 3 days is now flashing up again and the engine light is back on just wondering if anyone else has had this issue and may now what the problem is. Thankyou

Hi and welcome. The EML comes on for varying reasons and should throw up some error/fault codes and they should then be logged to the ECU. These error codes would typically tell you what the ECU believes to be faulty. Without the code numbers, its going to be practically impossible to diagnose your issue.

If you can get the codes, post them here and we might be able to shed some more light onto your problem for you.

Hi I've had same problem, EML came on and fan came on straight away, when checked it said engine misfiring, changed spark plugs, ok for 3 to 4 days then came back on, any ideas ?
thanks

As per my reply above. We need some form of error codes to assist you further. Without them, can't pinpoint your problem.

Yep. needs code read by the dealers, or buy a code reader off ebay

I doubt you will get rid of fault codes by changing spark plugs

There are stacks of fault codes which will indicate what is wrong
Maybe disconnect the car battery for 5 minutes to act as a reset, but doubt it will help

Dave coster mine the did same thing misfiring and the fans came on changed the spark plugs and it was okay for a few days then the light came back on.

I got a code reader and it came up with nine faults which were
P1336
P1337
P1339
P0087
P0353
P0352
P1338
P0313
P1340

After searching these faults the majority of them are about misfires and coils, we're going to change the coils and see if this fixes the issue.

Do you have a THP Masonabi and Dave coster? If so, could well be carbon build up in the inlet valves, which causes the misfires etc. The good old walnut blast at SP Tuning by Jamie will fix that.

[Chris_Blue]

Agree with Funky. That amount of fault codes, engine may well need a blasting
Could run though some BGK44 see if that does any good, but will only be a temporary fix, engine may need cleaning

[Masonabi]

Funky Ye mines a THP, We've changed the coils and it took the engine light off seems to be running fine at the moment.

[Masonabi]

Was fine for four days after changing the coils and now I'm getting the same warning up and engine light on again

It's defo carbon build up in your inlet valves. Your THP needs a walnut blast. Get in touch with Jamie@SPTuning.

was trying to break Masonabi in gently, with a few hints to start. LOL

[Masonabi]

Do you think it is alright to drive until I do get the walnut blast, the engine light isn't always on it goes on and off like one day it's on and another it's gone off.

[Funky]

It might be a bit juddery and EML's aren't a good sign IMO and need sorting asap. How long before you can get booked in for your WB?

Carbon clean and new fuel pump transformed mine. Both needed doing after getting misfire codes.
I did both DIY no more than a weekends work.
