have a 2015 mk3 1.4 diesel

just came up with this code, anyone had it before?

is it as simple as cleaning the sensor?

Not necessarily but as you know diesels are particularly dirty so it pays to keep them clean by timely servicing and cleaning of engine oil and filter, air filter, and perhaps now and again putting some "city" diesel in rather than always the cheapest you can possibly get.

 

If you clean the MAF do buy the correct (MAF) cleaner for the job and take care with the cleaning - but do also look at the air filter (compared to a clean new one) and see if the air filter box and tubes are reasonably clean and clear.

thanks for the reply

 

in the end it turned out to be a broken wire on the connector to the maf

 

Well done on finding it, and thanks for reporting back.

 

Too many people take the error code as the solution rather than as a starting point for diagnosis, often shooting the messenger by replacing the part that reports the error code instead of investigating further.

 

Sorting the wire on the connector is the repair but also cleaning the MAF (if required) could be preventative maintenance in the same way as changing the air filter and engine oil & filter.

 

You now know how to treat many error codes you can get.  Good luck.
