Looking for someone in the Bracknell are a who could plug my A4 2.0 tdi in for diagnostics. The glow plug light has started flashing under hard acceleration in higher gears but no loss of power. Centre brake light fault coming up occasionally and engine light came on and stayed on. Replaced brake light switch this morning and engine light went out but centre brake light has come up a couple of times and glow plug light flashed a couple of times.
