Title: Jetta mk4 AWW 1.8t bin on 2.0L ecu.
Post by: ct17 on September 24, 2015, 10:54:38 PM
Hi guys, i have an 01 jetta mk4 1.8t aww engine with 06a 906 032 DL ecu, and just picked up an 2.0 8v ecu 06a 906 032 MD (immo 3 car), reading in the forum, i turned immo off on the 2.0l ecu, and flashed an 1.8t bin 06a 906 032 HS bin in to it. Car started and ran fine, but after a few hours, MIL came on, read the codes and throw:

16622/P0238/000568 - Manifold Pressure/Boost Sensor (G31): Signal too High
16497/P0113/000275 - Intake Air Temp. Sensor (G42): Signal too High
16502/P0118/000280 - Engine Coolant Temperature Sensor (G62): Signal too High
17523 - Oxygen (Lambda) Sensor Heating: B1 S1: Short to Ground

what can it be? with the original DL ecu, there is no MIL. Bad bin? bad flash? try another bin?

sorry for my bad english.

im glad none of your options include "its the completely wrong ecu for the car and thats why it doesnt work".

some of you people need to use your damn brain.

ive read on another topic someone else flashed 1.8t bin on 2.0 ecu successfully and his car ran fine with no problems, just thinking if can be a bad bin file. sorry

As dumb as it sounds, I'm sure I read the same thread where it was stated that it worked.  I wasn't sure that the 2.0 ECU has the capability to drive the N75 valve.

The boost sensor might be an issue too, since the ECU might have hardware internally (resistors), etc, that only allow atmos.  I'm not sure.  Still, buy an ECU for your engine, not an ECU you think you can bolt in. 

If you spent money on this ECU and it's wasted, you're going to have to spend even more buying the right one, and that seems broken.

some peoples definition of "fine" may not be held to as high of a standard as other peoples.

i cleared the codes again, only short to ground on S1B1 o2 sensor, HS bin was 0006 sw, flashed 0008 sw, no fault codes at this time, car pulls and drives fine, i will update if MIl come on again. perhaps the 0006 sw has issues with burning 02 sensors prematurely.

dbw 2.0l can drive all 1.8t hardware including, but not limited to, n75, n249, n205, MAP, IAT etc.

single processor 2.0L ECU hardware is identical to transverse AWP single processor ECU. Same for dual processor <-> dual processor.

HS file that OP is working with may need the eeprom cloned aswell.

Is the MD box a single or dual processor?

Software wouldnt short o2. new ecu may be fried if you keep getting o2 short code and you've clear eeprom of any codes.

I run 1.8t HS software on 2L ecu and it work very good, no CEL, boost is normal, run perfect...

this has not been my experience.
i have tried this before and no matter what it always throws some type of o2 fault code and seems all around not very happy.
original 1.8t flash and e2p files.

hmm our experiences differ then. I've used several 2.0L ecus as replacements for 1.8T. Anything from simple stock replacement, to stage 1/2, to big turbo tunes.

Was the reason you had to replace ecu because the old ecu had the o2 code and was fried? If so, could the o2 code be stored in eeprom and you cloned the eeprom?

I wonder if it's specific 2.0 ecu's that work. Do you have any of the part numbers that worked handy? I have a few 2.0's on hand and cars to try them with.

032FP and 032FN for sure. I'll look back and see if I can find others I've used.

udpate: no fault codes.

i´ll be trying more 2.0 ecus.

*The MD box came from a crashed 03´ jetta 2.0 Auto. it is dual processor i guess. (two big infineon chips?)

i have a customer's car (AWP, K04, 6mt) that is currently running off a 06A906032MH, which is a AVH 2.0 auto, and its flashed with a known good "canned tune" stage 2 06a906032RN.bin and a universal immo off eeprom.  it has a bad o2, or so the customer stated beforehand.  the original ECU had issues from a APR solder on chip.  i couldnt scan it properly, not much worked right, and it barely ran.  this was done to get the car to a drivable state, as it was nearly useless beforehand and is a daily depended on vehicle.  the MH box was the only spare ECU i had on hand at the time.   

after getting it running with this ECU, i noticed that it is in fact throwing codes for the o2 and something related to the n75, which were originally thought to be legitimate issues.  after coming across this thread, its gotten me wondering.  i forget what the codes were, but i will be able to see them again in a few weeks when they bring it back to me.  the n75 code, and inability of the ECU to control it/boost seems like a plausible issue, as it spikes to 25psi and looses its mind, but if you throttle it and keep it below 20psi, it runs perfectly.  my temporary solution if necessary to continue this way for a little while was to install a manual boost controller to keep the boost from climbing uncontrollably and causing lean problems.  when it comes back, i plan to flash the same .bin and eeprom to a AWW manual box i have recently acquired, and see if the same things continue.  that way i will know for definite if the AVH box is the cause of the boost issues and o2 code.

Just tried an 06A906032MD ecu in a 2002 GTI with an AWP engine code that uses 06A906032SK. Boost control worked fine, but threw

17524 - Oxygen (Lambda) Sensor Heating; B1 S1
            P1116 - 35-00 - Open Circuit

After a short 5 minute drive. Car had no codes with the original ecu.

Looking at the wiring diagrams they both use what looks like a wideband and all the pin locations are the same. Exact clone of e2p and 800BB was made. I'm surprised this was the code it threw..

ok ive ordered a 06A906032FK ECU from 2litre EU AZJ
tested it for a 10mins run - all working good

seems that its ok with a 2.0 me7.5 EU ECUs but not US because i was trying to flash 2.0 litre US BBW flash to 1.8 ecu and its bricked

A BBW ECU is a "special" California emissions spec, and is ME7.1.1. 1.8t is (typically) ME7.5. ME7.1.1 and ME7.5 are NOT cross compatible. Your findings there are documented and well known prior to this.

Late face lifted New Beetle's do have 1.8t's with ME7.1.1, and would theoretically be compatible with a 2.0 ME7.1.1 ECU, but I have neither on hand to test with.

Very few US spec 2.0's are ME7.1.1

not to beat a dead horse, but i've crossflashed at least 15 2.0 ecu's. last being an 032MG from a 2.0 5spd 03 beetle, to 032HS, then realized you can flash to 032HJ euro a3 software.

032FK ECU with 1ML906032A keeps throwing P1115

Stock ECU doesn't have this problem. Car runs, lambda feedback seems fine so annoying issue. Makes for a good emergency ECU though  :)


Edit: lambda seems to give feedback but values are very much off for some reason

The 2l ecus are different, specially the wideband controller / heater circuit. Cross flashing them are a hack and it will not run correctly. Really anyone who says it will has no clue on what they are talking about

been running a 2.0 ecu for over 3 years the only issue is HEATER CODE runs fine boosts fine...

With the "heater code" you lose closed loop lambda control / long term fuel trims... "Running fine" I guess means running the wrong ecu in open loop all the time because of a fault code... You can however configure some codewords to keep the code off and closed loop active... but closed loop doesn't work properly because of the hardware differences. So realistically the best you are going to get is what you have now, the wrong ecu running open loop with a cel. They do not even have the same wideband controller and the circurty for the o2 heater is missing some components compared to the 1.8t. Check your short term fuel trims sometime... You can tell this guy doesn't do any data logs lol

The car runs "fine", hell the board looks very much similar enough.

The only real problem here is that for whatever reason lambda values are very much off, as such it's really nothing more than an emergency ECU for me now.

Fun experiment but can't be arsed to figure out the lambda issues, a proper ECU is just a couple of $$ more so it's of no use really.

If you open the ecu and look at the wideband controller you would see that they are not the same, additionally the circuitly is not the same. When it errors out from Heater circuit closed loop lambda is disabled.
