Hi I have a Audi A4 3 tdi sline Quattro on a 06 plate keep getting engine management and traction control light coming on I’ve replaced o2 lumber sensor which it said plus Accelerated module turbo pressure sensor air mass flow sensor all Best makes but drive for a few miles and engine management light and traction control light coming on but every now and again gos away but then goes back into limp mode doing my head as not a bad car any help much appreciated 

Hello Rory,

Does the ABS light also come on with the Traction control light?

Kind regards,

Gareth. 

Glow plug light flashes and traction light too 

Might be worth a diagnostic check if you haven't already. I'd also recommend getting a battery test as a failing battery can throw up electrical gremlins. Also the traction control light could be caused by a failing abs sensor. 

Definitely calling for a scan by either VCDS or OBDeleven. Sounds like there is more than one issue there.

Shame the OP joined and last visited a day later, and hasn’t commented on any advice given. 

Admittedly I was late to the party too. Alas, we tried.
