SOMEone said this on another forum (any truth to it?) 021 906 258 CH is OBD1 and has an immobilizer, so changing an ECU will require a recode. if so how do i recode? argggg .... does this also apply if i buy a new ECU?

NEED ECU FOR 1993 VW CORRADO VR6 SLC 2.8L (AAA) DISTRIBUTOR PART NO. 021-906-258 CH PICKED UP A 021-906-258-AT BY MISTAKE :( USED I DONT CARE, I NEED IT OR COMPATIBLE FOR MY YEAR / ENGINE. PLEASE IF YOUHAVE REPLY HERE AND ALSO TO [email protected]

GUYS PLEASE HELP!!! 1993 Corrado Vr6 SLC 2.8. had a crash (2 years ago) finally got it back together.... Mechanic said it would not start and it was "the board" in the ECU and he changed it out from another vr6 passat (SO HE SAYS) I DUNNO! ENGINE holds back when you push it @3500-4000 rpm as you switch gears it goes higher rpm in higher gears. i'm thinking whateve he put in is not compatible. Now i ordered a ecu (thinking i had coilpack vr6) and got a 021-906-258 AT ecu ( naturally car doesnt start since its distributor) here is my Delimma... the ECU casing in the car says 021-906-258 CH ... when i look that up i never get anything except on one site it says Golf 2.8 vr6. now my question is.... is that the correct ECU number for my year / engine (AAA) i am asking this because i cant get a straight answer from this A-hole . did he change just the board (if so that means the chipset is changed as well) or the entire module! Really what i want is to just dump the entire ECU and buy another one but I CANT FIND ANY with CH behind it.. only C. What do these letters at the back mean? is there a compatabile ECU? i've changed just about everything, plugs, wires, MAF (new oxygen sensor is coming) only thing i havent done is change the crank sensor. Its very hard to try and diagnose something when in the back of your head you have this thing about him changing the board in the ECU and cant tell you from what it came or even give you back the old one he supposedly took out. Agravated as hell, i can buy new stuff all day and this ECU thing would still be in the back of my head.... its as if it hitting a rev limiter at 3500-4000 rpm in 1st, 2nd gear. some help on the ecu codes would be great as everything on the net is sketchy at best.... whats a compatible ECU number for my year/engine (AAA) vin? is the CH correct one? (only asking as i dot know if he changed entire unit or just the board, cant get straight answer... all i know is i bought a brand new ECU with AT in the back and car doesnt even start so i am guessing thats for the coilpack version.

Well got screwed lol.. I dont have coilpack and got a coilpack ECU LOL.... alright the hunt is on for a Distributor ECU (Car doesnt start with the coilpack version)

Got one off ebay.... Coilpack (which i thought i had all along) today i checked and its distributor!!! ARRGGGG will this work now?? another thing.. took out the radiator fan (belt was loose to the dummy fan) and after re-assembly fan doesnt come on period!! believe i have the wires on the temperature switch thats at the radiator wrong... can someone help me out please on how to wire (its 3 loose wires) Red, Red white and Redblack... think i tried every combo to no avail.. plus i dont know if maybe now that i unplugged the fan harness its not getting good connection (it used to be an issue before with the old fan but that was because the prongs on the fan itself were rusted away this is a brand new fan and was working fine before i took the fan shroud out) how can i 1. test the fan 2. bypass that damn switching crap (maybe have it running at all times)

2 years back i had a front end crash... and thanks to the guys at TheDubNutz its now back together after 2 years. It would not start mechanic said it was the board inthe ECU and he got it started and running with a board from a 2.0 v6 Passat? if i rev the engine at 3500rpm it seems as if it goes into rev limiter sort of thing (this is in neutral) while driving if i gun it it holds back... He CLAIM!! the board is the same board and even the numbers match but i doubt this very very highly and i'm thinking this is the reason. I've cleaned the MAF, Changed Fuel filter, Changed Plugs and Wires the only thing i havent checked yet is Arching at the coilpack, i'll do that in about an hour when it gets dark. Really want her moving again... ps as i drive if i dont gun it and go thru the gears and slowly give gas it will with no problem go over 3500 rpm, but if i want to take off fast like i used to burning tires in 1st 2nd and 3rd that dont work no more :( ps its a 1993 Corrado Vr6 SLC. Mark From the Caribbean. think i better start lookign for a new ECU on ebay.

Good JOb. Let us know how it holds up though, do they have this for the tan leather??? if so post link.

BUMP! ANYONE?

Need quick response, anyone know the diameter of this pipe??? have to work tonight and no Trans :(

OK thanks for the tips, as for the radiator its brand new along with its hoses.

Very nice, i would be more interested though to find out if that level indicator tube will hold up under the pressure. Other than that looks very clean

WEll being a car buff and working on may engines (American cars) sounds like Valve tap and really bad too... Did you do timing lately? If a tensioner is week it can also jump a tooth and create the same situation... If i were you i would have that checked immediately. doesnt matter that the chain tentioner is on the other end, point is its a valve tap and that could only mean off timing causing the valve tap.

Ok Mates, Got home (Whew rough day) got out my 8mpx camera and went downstairs and stuffed it an my old carcus of a arm down near the drip and shot this picture :) Its the hose going it what looks like the oil filter? i dunno just got my car not to long agos so dont know much about it :) Anyways you can see the rip, im hoping i can just loosen cut and pull the excess to restall after the rip, if not i'll need to go out and buy a length at the same diameter.

Will this work??? wrong year but hey even if the connector is different i can work around that Clicky

OK, got to thinking and i remember seeing the 3 sensors in a row next to eachother, no the leak is not from there, its further to the left of those, i read something about a hole going to a water block might have gone bad ?? Guess i just have to get a flashlight and try to crawl under there to check, i have a kit on and its not like i can just scoot under there to check anymore LOL.

Thanks a million guys, i will definately check these things.. and yes its a 93 VR6 SLC

Well guys, Last week my water level light started flashing, got home and sure enough the res was empty.... let her cool down and filled it back up, and i noticed at the very front of the engine some water dripping, as i kept watching it it just stopped and figured hmmmm ok :) ran the car for another week and all was good level was good.... on the way home yesterday the light starts flashing again as i was driving and i kept looking in my rear view mirror and i could see the trailing dots of water on the road. So anyways parked her up and said, i will tackle it tomorrow morning. Well this morning i went in the car and started it up and heard this weared noise, after closer inspection its that little electric pump, guess its the Aux water pump.... its making a noise sort of like an old electric motor on its way out, or the empellar loose?? do i need to make a video? LOL Anyways my question is does this pump have anything at all to do with circulating the water??? i will certainly hope not, from what i hear its simply for cooling after the car is shut off??? Anyways any idea where this leak maybe coming from? from what i can see its almost dead center on the car in the front... I filled it back up and im squeezing the hoses to feel if there is any pressure in them from the water and they all seem empty to me and not even getting hot.

Gills were not done, comes that way as part of the Z3 style fender... Check ebay for it they are 180 bucks both side fenders.

BBS RIMS yes but not original :) Well here are a few pics i promised, kinda busy at work so cant really go out to the real exotic places in time (during daylight) to get much shots, but i will :) PS. Still waiting on my InPro halo's :) Ok lets see if the forum will allow me to show all the pics in one post :)

Hehe, yeah and trust me its the only one on the island. Gets lots of looks. They ask me all the time, is that an Audi?? i say Yeah its an Audi thats why theres a VW in the front LOL. Yes picture was taken at the golden hour to get the blue effect on it, so cant really see the body kit all that well although you can make out the side skirts and rs4 front bumper and z3 fenders, will take some at the beach and stuff on the weekend.

Well '93 Corrado SLC VR6 is finaly done. Good guys over at Dubtechnic sent me my kit, was a few snags in shipping as the main guy over there was on vacation but all came eventually in seperate pieces. This is the RS kit, only front pic for now will post more later on tonight when i take some pics under some neon lighting. Also have on Z3 fenders (they are way cool and very well priced) Fender fogs/turns are from In.Pro, perfect fit as usual, waiting for my Inpro Angel Eyes to come in then she is totally complete.

in my case its not that, as mine only does this crazy crap during the day, at night in cooler air it doesnt do this...

Thats your idle control valve doing that, mine was hunting like that and it was the valve.... still have another problem as well which i thought the icv would have solved but at least its not hunting anymore.

Having the same problem, at first i thought it was idle control valve and for a few days there it was running fine after putting that in but today is hot and its doing it constantly now again. if i put too much gas, not even wide open throttle it will rev up to 2K then jut bog out abruptly, almost like it got no fuel, fromt here its all down hill i have to keep playing with the throttle and dry to drive it under 1500 rpm.... wondering what the hell it could be... Fuel pump? Pump Relay? Pressure regulator??? i'm lost, dont want to go out buying a new fuel pump and its not that. i am sure someone has run accross this problem before, but i really havent gotten any helpful responses up tell now other htan puttinging it on VAGCOM which i did and thre was no trouble codes, all sensors are fine.
