It may be down to something simple like the fuel filter needing replacement. I assume the EML is not illuminated and you have no warning messages. Best thing is to have the codes read and go from there!yµ (idµ - eAµ) ψ=mψ

Very vague response this, but my D4 had an issue with some turbo switch on the second turbo, causing power issues, reported in the ecu.
When I got the car, the errors were there, but stupidly I didn’t save them before resetting.
Paperwork confirms they are fixed tho’
My driving of it, the car performs well, but only so much you can test at a max speed of 50 kph, so Spain ..... here I come (once I get the logbook)

The following should be eliminated as possible causes:
Brake light bulbs
Auto gearbox linkage
Faulty brake pedal switch

Is the MAP sensor thing an issue on the D4? they are notorious for clogging up on the D3 you tend to notice a drop in performance and MPG.
Dead easy to fix in about 15 mins. Take of engine top cover, undo screw, remove, wipe, squirt of electrical clear, wipe and refit.
It might not be that, various other things posted are possibles, but this one is easy and free.Disco 3: Lotus Elise S1: Ferguson T20: Audi A2
