Hi

I am the proud owner 3.2 53 reg A3, at the beginning of the summer I started it up one morning and it beeped at me 3 times and the power steering was working, so I (stupidly) took it to the Audi dealer and asked them what was wrong, they took a look and said I need a new steering column (about £1200). I asked if they could give me a bit of time to get other quotes, they returned the car with the steering working, I asked them why is working now, the guy explained that they can clear the faults and so the computer thinks that everything is ok (for this privilege they charged me £100). He also said that that has not fixed the problem but it will give me a bit of time. I brought a 3rd party VAG-COM cable off eBay and got the software of the internet went on and tested my new cable and software, all ok and it was so I put the cable to on side until I needed it.


Got in to the car the other day and the engine warning light has come so I got out my cable and had a look at the warning. The warning that came up was P1640 Internal Contr.Module (EEPROM) Error 18048, so I cleared it and went on my way (with the intention of googling it when I got home) now this morning the steering problem returned. So again I got the cable out and tried to clear the error and when I try to go into any controller option apart from 01 – Engine I get “No response from controller” error. I did google the 18048 error and from what I have read I may have a bad ECU.

1. Can anyone give me a bit more info on the 18048 error and possible fixes?

2. Would this 18048 error affect me getting into other controllers in VAG-COM?

Thanks


Spike

second question you should be able to get into most control units but you may require a higher version of vag com to swap the engine control unit

I ordered a new cable (this time serial not USB) and received it this morning, I have tried it and it still only gives me access to the engine module why is this???

1421here is my version of vag com which reads everything.what lead have you got and is it can bus compatiable as newer a3 communicates via can for diagnostic but you can access engine electrics via k wire.I suspect you only have K wire lead and need to upgrade to can for full diagnostic.Refer to ross tech for correct lead and software down load.This is A3 log of engine management only

Try unplugging body throttle and turn key then plug body throttle back in to change ecu values and you'll get responce from ecu
