Hi Gang
My wife's Q5 has the amber engine light on twice. The fault is P20B800 Reductant Metering Unit Heater Control Circuit High.
My local Audi specialist (not a main stealer) says options look like:-
- New complete adblue tank , pump and heater c £2k plus fitting
- Adblue system delete c£250, with doubtful legality.
Any ideas on either a likely cause or a UK based specialist who has a reasonable chance of fixing it at a fair price.
Many thanks
Nick
