Question about 1998 Audi A6
The ABS Pump started to leak on my 1998 A6 and apparently there models that could fit the car depending on EDL and traction control. How can I tell what my car is equipped with? I don't have any of the original paper work

if its a climatronic head unit and there is a fault the head unit sometimes flashes to tell you there is a fault,diagnostic equipment should be able to pin point your problem

you have a thermal fault i the abs modulator <ecu bolted onto pump> the rev counter fails because this signal fails to get from 13.8 volts to zero it only manages to get to about 3 volts this is very common on bosch 5 series mine had pt code bosch 0273004285 and is notorious but easil removed and sent to bba here in uk or others in usa you will have to remove wheel then washer bottle then modulator but car stiill drives when removed the esp needs signal from abs and fails at same time also loss of tacho signal puts il light on i tried to find second hand one biut they didnt work have sent mine for repair<you need a microscope to do it> will post when it comes back ps easily confirmed by spraying abs pump.modulator with freex=zer spray did it to mine and fault dissappears untill warm again nb even when cold i bet if you brake hard a couple of times it will fail please let me know if your pt number is same as mine and if this heelps it drove me nuts
