Title: 4B0 906 018 AA - compatible ECU Post by: vtraudt on July 05, 2016, 09:48:21 AM I want to buy a spare/swap ECU.
Car (European model, 2000 A4 Quattro 1.8T manual) has 4B0 906 018 AA. Hard to find in the US. What comparable ECU can I use? Title: Re: 4B0 906 018 AA - compatible ECU Post by: SB_GLI on July 05, 2016, 11:12:59 AM This is narrowband ecu? If that's the case, probably any ecu from a narrowband passat will work. There are probably a load of other ones that would work as well, but I would be most comfortable with that.
If it is a narrowband ecu, might want to consider a wideband conversion with a wideband ecu ala CH/CM Title: Re: 4B0 906 018 AA - compatible ECU Post by: vtraudt on July 05, 2016, 11:51:35 AM This is narrowband ecu?

If it is a narrowband ecu, might want to consider a wideband conversion with a wideband ecu ala CH/CM Currently wire count on 02 sensor on the car. Other method to determine if wideband or narrow? Short of posting on Euro forums? Title: Re: 4B0 906 018 AA - compatible ECU Post by: SB_GLI on July 05, 2016, 12:46:48 PM Currently wire count on 02 sensor on the car. Other method to determine if wideband or narrow? Short of posting on Euro forums? Log block 031 with VCDS. You'll have actual lambda values (in addition to specified) in there if it's wideband.

Title: Re: 4B0 906 018 AA - compatible ECU Post by: mickeyd1984 on July 05, 2016, 10:30:48 PM Seems like a 018p ecu would work if its narrowband me7.5 ecu? That would be my guess anyway
Title: Re: 4B0 906 018 AA - compatible ECU Post by: vtraudt on July 06, 2016, 04:10:30 AM Does someone know if the 018 AA is wideband or narrowband? Note: don't have ECU or car physically here.

Back then, i don't think they had wideband yet.
So I would assume, just like the 2000 ATW we have here, it is still a narrow band. Title: Re: 4B0 906 018 AA - compatible ECU Post by: _nameless on July 13, 2016, 06:08:21 AM IF ITS A 97 ITS A AEB. ATW IS ME7 NARROWBAND
Title: Re: 4B0 906 018 AA - compatible ECU Post by: vtraudt on July 13, 2016, 06:22:17 AM The car is a European 2000 A4 Quattro 1.8T manual.
I have just seen (ebay Europe) the 018AA listed for 1997 Passat (but doubt it since that would be drive by cable AEB engine as far as I know). 2000 A4 here is in the US is ATW (narrow band, electronic throttle). The 018AA is often found in A6 with the 1.8T is seems. So no compatibility information out there? Title: Re: 4B0 906 018 AA - compatible ECU Post by: mdz on July 13, 2016, 01:08:02 PM 018AA is narrowband dbw APU engine ecu found on A6, Passat and A4. I have one but I'll use it on my project. I can post eeprom dump or bin if it's any help. ::)
Title: Re: 4B0 906 018 AA - compatible ECU Post by: _nameless on July 13, 2016, 02:33:33 PM Just use the 018p or buy a wideband sensor and ECu to convert to wideband the chip in the pic is what ou need
Title: Re: 4B0 906 018 AA - compatible ECU Post by: brs on April 19, 2017, 01:31:20 AM i know this is gonna sound a bit weird but can I work to wideband ECU as a narrowband ECU? :)
Title: Re: 4B0 906 018 AA - compatible ECU Post by: mister t on April 19, 2017, 06:13:40 PM you can most likely use a 4B0906018P ECU. At least that's what my North American 2000 A4 DBW narrowband equipped car uses.
