Common owner-reported themes
Not diagnostic advice — themes owners often document in service history. Always verify for your exact engine and year.
EA888 intake-valve carbon
Direct-injection TSI/TFSI builds carbon on the valves. Walnut blast with mileage and photos supports a clean-running claim.
Water pump and thermostat housing
EA211/EA288/EA888 cooling parts crack or weep. Invoice the complete pump/housing, not a coolant top-up.
ZF 8HP fluid service
The 8-speed needs fluid on interval even if the sticker says “lifetime”. Harsh shifts usually mean overdue oil.
