Webasto! Why won’t it work on its own…. VCDS enabled??

Just pull the ecu from the cradle and read the firmware version on the label
That is the surest way to know

Hi again Paul,

Can confirm, from visually reading the stickers that I have 1 originally running firmware 1282 (project EUD) and the other originally running firmware 1514 (Project EUD). Both have climate control.

The only sure way to confirm any ideas or assumption, without further input from the wider community, is to plug a firmware 1281 ECU into both my fleet. As I said above, I also have another early AMF with Webasto and climate control here that I could also plug it into. Obviously I’d have to do the iced water method unless it was cold enough should you be able to send one down for experimental purposes.

More than happy to help out as I’d truly like to understand where the problems is as I’d like the fuller map all year round, whilst not loosing functionality of the Webasto when the ambient conditions are met.

Kind regards,

Tom

We already have a plan hatched for after Xmas where by you send me both ecu’s
I will revert the 1281 ecu to 1281 adjusted firmware and 1514 to adjusted firmware on code block 00002
All will then work in terms of max available power and working webasto

Hi Paul,

Hopefully I’ll be able to identify an opportunity to send both ECUs at the same time. It’ll not be easy though as both A2s are used often. It might end up being just 1at a time so we’re not left with just the A6.

I’ll hopefully sort something out.

I was only suggesting testing a firmware 1281 ECU here as so far we’ve not got to the bottom of this issue. The only input from a climate control AMF A2 has been my 2, without further contributions from the wider community it’s a simple way of elimination. I’d also rather have a concluded answer to the issue before I commit so potentially sending up 2 ECUs separately when we don’t really have an answer.

Kind regards,

Tom
 
Mines an AMF with climate but standard ECU (2001) if thats any help ? Webasto not firing up but that's due to it thinking the internal temp in the webasto is 120 deg ish

If your can check engine ecu measuring block 016 and report the bit pattern with econ button pressed (lit up) and not pressed both with engine running for at least 30 seconds
We also need the ambient temp from the dash display and the coolant temp from block 001 or 002
Please confirm firmware version (top right box after you log into engine ecu) and the coding number from the left hand side

Cheers. Paul

Hi Mac,

I agree as I’ve been unable to find anything myself either. The only air-con adjustments I’ve come across are on adaption channel 060 within 46 CCCU, but think this is not connected and is just for the heated mirrors or something - I’ll have a play with the adaptions to see if that changes things at bit 2. I’ll. it getting this until this evening though. It’s probably a false lead. It worth checking I guess to eliminate the reason why my 2 climate control A2s won’t fire up whilst running map ‘5.

The answer is out there, we’ve just not stumbled across it.

What I have discovered though is that different remapping outfits look to code the engine slightly differently. I’ve got a report on my laptop from a Webasto enabled AMF engine and its engine coding is 10002 and not 00002 or 00005. The pop up hint doesn’t indicate what the proceeding 1 is for but know the map was added by Stealth Racing. I cannot confirm if the Webasto fires up in this vehicle as I don’t have it here and to be honest I cannot remember who’s A2 it was. It was early last year and cannot remember what I done yesterday.

Kind regards.

That's interesting as Mr Silvers ecu that came with the car is coded 10005 wonder if that's been to stealth in the past?

What I can tell you for sure is that as tdi 1.4 A2 left the factory the engine ecu coding was 00002
The only other coding option was 00005 which was an identical set of maps to 00002

So if your ecu is coded to 10005 then it’s not standard Audi firmware in the ecu
Who put the firmware on the ecu is a mystery unless you have something from the previous owner / service history to establish the source of the firmware

Looking at the sticker on top of the ecu you will see the firmware version that it was originally programmed with this being a four digit number For the AMF engine 1281 or 1514 are the two common ones used on engines paired with the webasto Aux heater

The AMF engine was fitted to different cars in the VAG range and they have their own firmware numbers and associated coding
I did have a list of these but fear it was lost some years ago with a hard drive failure
I remember the coding being different but in all honesty I can’t recall if there was a 1 at the beginning of the coding

Take the ecu from the other earlier A2 which will be 1281 if 51 players or earlier and use that
It’s not going to run for more than 1 second due to the immo but your only trying to review engine ecu block 016

Morning Paul,

I can certainly do that but not sure what this will achieve as it’s a standard ECU which has’t left the vehicle since leaving the factory. I thought we were trying to understand if something was mistakenly altered during the remapping process as I guess a stock ECU will be just fine and would present a string of 0s in group 016.

I can do this though if you think it’s worthwhile.

If it would be better having the engine running then I’m happy to match the ECU to the difference vehicles, easy enough.

Kind regards,

Tom
 
I already know that the 1281 firmware either std and altered works in a 1281 car
What I’m trying to understand is does a 1281 in terms of block 16 and the first and last bits work correctly in a car which is meant to have 1514 firmware
Ie I’m trying to track down why the webasto still kicks in on 1514 with the engine coolant bit set to 1 because 1281 does not behave like this

What about Group 016, Block 2, Bit 2, (ECON), which was the original shutdown condition with Map 5, in later software? Is that sorted? Did I miss it?

To match the ecu is it just the key you need to code the immobiliser or do you have to alter the instrument coding?

Hi Tom,

There is a great Ross-Tech endorsed YouTube clips that I sometimes refer to if I’ve not done the process for a while:


You of course need to have first obtained the SKC for the vehicle along with from the replacement ECU.

Once you have both then the clip above talks you through the process.

Kind regards,

Tom
 
I've fairly sure ive seen for sale a manual heater control for an A2 which doesn't have an econ button. Mine has the econ button and a webasto. Maybe non climatronic manual early cars without webasto say 2003 on didn't have the exon button for the electric aux heater? Would this be a idea for the confusion?
