My Mk5 R32 has started throwing the above error codes and yesterday illuminated the check engine light. Anybody had experience with these codes or know common things I should be checking? The car still drives fine but does seem to stumble a bit on startups so it doesn't seem too serious.

How are the plugs?
"When crank times increase due to worn-out ignition components, ie, spark plugs, fuel dilution of the oil causes fumes to collect in the intake and breather systems causing major adaptive requirements, and turning on the MIL...

As with most OBD II vehicles, fuel trim is influenced by inputs from the MAF sensor as well. Any leaks in the intake boot upstream of the MAF can adversely affect fuel mixture, again causing the MIL to illuminate...
But also take a look at the intake ducting itself. The boot is actually hard plastic and is often hardened and easily broken during air filter replacements..."

Plugs are only 15k (Kms) old. Intake is also fairly new and not damaged. Recently cleaned the MAF aswell. Can't see/hear any obvious leaks from hoses etc.

Car is due for a service this month so if it's not fixed by then it can be VWs problem.
