2013~2016 Cx5

[Purple8]

I have a Cx5 diesel 2016 2.2 with 84k on the clock used car.

Purchases it at 82k

Last week it came up with a vehicle system malfunction

Had it checked out

PO421-00 and PO6DE-00 error codes

Was fine driving for half an hour, then the engine light and engine oil warning light came on.

I was advised to take it on a good drive for 60 miles monthly.

I have only had it 2 months

Anyone had similar problems???

What did you end up doing ?

Thanks in advance
