P0401 EGR Valve code, Also Air Con fault

[daveworkington]

Hi All,

P0401 : EGR Valve - Insufficient Flow

I keep getting this code. I have cleaned out the EGR valve, and the valve piston moves and returns when pushed with a small screwdriver, so its not jammed. Presume the fault is electrical / data error?
Will Vag Com be able to test the valve for correct operation before I pay £130 for a new one

Also, my air con doesnt work when the weather is too warm (rather defeats the object), but works fine on cooler days. I have had it re-gassed.
Would Vag Com be able to diagnose or recode this problem?

Many Thanks

Dave

If it's the same as mine, expect:

Address 8 One fault found 00818 sensor for evaporater outlet temp (G263)
30-10 Open or short to B+

Couldn't be recoded as it was a faulty sensor
