    RNSE MkII - CAN causes battery drain

    Anyone had a chance to look at their nav/radio coding for RNSE? Could do with the cluster coding & channel 62 (infotainment). Changing the cluster will have to be a last resort as I’ve been reading that it’s a costly option (recode immobilizer, etc at Audi so £££). Do you know anyone on ASN...

    RNSE MkII - CAN causes battery drain

    Back to its old tricks again this morning so recoding the Infotainment bus didn't work. :wtf: The coding hasn't changed. I swore a lot then went to work. Thinking that maybe there was a dodgy connection or broken wiring somewhere, I took the cluster off this evening & resistance checked the...

    RNSE MkII - CAN causes battery drain

    Ok, I was having another look at this pita fault. For the last few weeks, I've had the can bus high & low wires out of the quadlock so that there's no power control from the key / door locking or any info on the DIS. I took them out as they were keeping the radio powered up (screen off but...

    Rnse mk2 install

    Allyn, I realise the date on your post but did you get this sorted? Wondered if you wouldn’t mind sharing the coding for radio & cluster. I installed a mk2 about a year ago & have had battery drain problems & can bus not turning off the radio when the key is out, etc. I’ve written a fair bit...

    2006 A3 3.2 RNS-E

    Not sure about the unit you’re looking to fit but I did have a similar aftermarket unit when I bought my B7. I fitted RNSE & one of the units pictured below & it works well. Bluetooth for RNSE auxiliary port. Might save you buying a different unit. There are a few sellers flogging them on the...

    RNSE MkII - CAN causes battery drain

    I’ve managed to stop RNS-E drawing current with the key out (I replaced the radio board but it wasn’t that). No, I didn’t drop-kick it over the fence Turns out it’s an Infotainment CAN issue. With fuse 15 (mini fuse 10A instrument cluster) still in, I removed fuse 39 (20A radio) & put in a...

    Alarm fault - glass breakage sensors

    I found the alarm glass breakage sensors hiding behind the C-pillars. The pair of wires go into a connector behind the rear seat side trim on each. Someone has had the right C-pillar off & broke the solder pad off the glass, hence my fault code, so I'll have to get some conductive glue & try...

    Audi a4 2.0 diesel bpw cooling problem 2008

    Does the temp gauge in the dash get up to 90 once you’ve been running for a few miles? What temp is the gauge at if the engine idles for a while? Although you’ve flushed through & changed the usual parts, it still sounds like a blockage at the matrix end so when you idle there’s no heat...

    Audi A4 Cab B7 2.0 TFSI

    I don’t know about cabs but I’ve got a 2.0 TFSI. Would be worth checking the engine code of any you’re interested in & find out what’s been done to it. There are loads of posts on here about those engines. Hopefully, someone with a cab will pitch in with common issues before you commit. I’ve...

    Alarm fault - glass breakage sensors

    This is the single wire connection at the top of the boot lid on the glass that's been mentioned on another forum. The track is only about 20cm long & doesn't link to anywhere so must be another radio antenna. It's definitely not connected to the rear heater circuit so I guess it goes back to...

    Alarm fault - glass breakage sensors

    I can only find the rear window status & it shows here that it's in tact. I took all the boot trim off & I can't see the sensor. I haven't found the other sensors for the alarm system so far in VCDS. There are 3 tracks on the side window. Can't see anything else that could be for the glass...

    Coolant sensor issue

    Darren, I changed mine on my 1.9 AVF B6. I think this is what you're looking for so I've attached a pic for you to look at. My engine wouldn't get up to temp so changed the sensor & it was green like the pic. Not sure if it's that colour just to easily identify an upgraded part. Must be...

    Alarm fault - glass breakage sensors

    Hi, my alarm keeps going off at random times when locked. Only the lights flash as I’ve already disconnected the siren from the alarm module in the lower rear right of the boot. Every time I scan it, VCDS says it’s the glass breakage sensor in the right rear side window - G184. I read that...

    RNSE MkII - CAN causes battery drain

    There is no AUX option on RNS-E. I’ve been checking the unit on the bench & it works fine. It doesn’t come on when it wants to or do random things so Im guessung whatever causes the drain is not radio functions. The only thing I can’t confirm yet are the CAN messages. This morning, the...

    RNSE MkII - CAN causes battery drain

    Thanks for your your reply, tgc. Interesting that you had a drain because of RNS-E. I’ll have another scan to see if the aux is enabled. Yeah, I noticed that VCDS thought that it had the navigation DVD drive in the boot (there isn’t one) so kept reporting that it was at fault. I’ve coded it...

    Retro fitting puddle lights

    I've installed puddle & warning lights on my B7 & all the front door lights work as they should. My car was manufactured September 2006 so I'm following the 'From 2006' wiring diagrams in the Bentley manual & I've confirmed that the wiring matches on ElsaWin. The rear doors won't light up at...

    I've installed puddle & warning lights on my B7 & all the front door lights work as they should. I didn't have to unplug anything. My car was manufactured September 2006 so I'm following the 'From 2006' wiring diagrams in the Bentley manual & I've confirmed that the wiring matches on ElsaWin...

    Battery drain...

    ....and while you're working out what's causing it, you might want to think about disconnecting the battery when you leave the car overnight or at work, if you can. I did this until I worked out what fuse to pull as I'd killed 2 batteries because they wouldn't hold a charge after all the draining.

    Battery drain...

    If it's just a basic multimeter then the current setting may only be good for 300mA or so. If the current draw is high enough, then it could pop the fuse in your multimeter. It'll depend on how long it takes for your battery to drop by 0.6-0.8V, but I'm guessing your drain is not more than an...
