Hello everyone, Can someone help me find the right MAF for my '99 Passat V6 2.8L AHA (99.9% confident it's AHA engine)? I have tried multiple sources and I believe that the part number is 078133471C. However, I cannot decide whether I want to go with VDO (Siemens) or Hitachi. Bosch does not...

Calling all 2.8 30v experts. I have a AHA out of a 1999 Audi A4 that I want yo use in a 2002 Passat. The problem is that the crankshafts are different on the transmission end. I would like to know if i can use the crankshaft out of the ATQ that is coming out of the Passat in the AHA. I have both...

Over the years there has been a lot of discussion about the differences between AHA & ATQ heads and ability to use one in place of the other. I hope this becomes the 'Definitive List' of differences. This is currently a work in progress, so give me a few days to get all my ducks in a row. This...

Hi guys I've got a 2000 Passat 2.8 v6 that I need to remove passenger head and was wandering if there was some procedures with pics anywhere thanks in advance guys

Hey guys, my girlfriends 1999 aha has been having some bad hard starting issues and also has been going into limp mode every once in awhile from the tcm getting an error from the ECU. Here are my scans, don't pay attention to the catalyst efficiency just yet, only a flex pipe leak. MAF was...

This an attempt to generate interest in a true bolt on no modification Aluminum flywheel with the 240mm RS4 clutch to adapt to the AHA / ATQ V6 engines. I have set a deadline of 2 working days to have a complete design of a 12-14 pound aluminum flywheel that will bolt directly to the AHA / ATQ...

like the title says, I'm replacing the downpipes on my B5 with an AHA motor. the newish replacement pipes have about 60k miles and O2 sensors already on them. I'm trying to pull the old pipes with the old sensors in place (flex pipes are shot). I have everything free except for where the O2...

I'm taking the engine out my '01 which is ATQ and putting the engine into my '98 which was AHA. 1) How hard is it to keep the ATQ components and use them in my '98? I understand the ECU would have to be swapped out and the accelerator pedal would have to be converted for ATQ drive by...

After making the decision to toss in the towel on my wifes 2001 GLS I have decided to go back to my getting my '98 back in working order. Brief history: I purchased my '98 back in the summer of 2006. I bought it from my then sister-in-law (which is incedently how my screen name originated) The...

Yesterday I notice burning oil for the first time ever with my '99 Passat 178,000 miles. After driving back home, oil light came on as I was entering my driveway. today pulled the lower engine bay cover off and it was covered with oil. I cleaned off all the oil from the bottom and front of the...

When initially started, (1999, B5, AHA, 2.8LV6, 115,000 miles) the engine exhaust is nearly clear and very much like a car that was started cold. As the car warms up, there is white smoke coming from the exhaust. It is not super dense, but enough. This is after replacing the heads that were...

I don't need them to be in good/working condition... I just need a set of OE axles, so I can turn them in as cores when I buy my Raxles. I talked to Marty today, and if I understood him correctly, I think I need a set that match the AHA Auto set that I would be buying... I'd rather not spend the...

Does anyone know if the fuel injectors are the same on ATQ - AHA engines? I have the injectors removed from the AHA motor, but I would like to know before I tear into the ATQ motor.

I believe my ECU part number is 3B0 907 551 DB. The ECU that came with my G1 setup and the G1 tune installed is 4D0 907 551 AH. I am assuming that a large part of the ECU programming is different between the two because the A4 B5 was not DBW among other things, e.g. IMMO, CAN Bus, etc. However...

Hey does anyone have a b5 AHA engine with the UNITRONIC stage one flash? Just trying to figure out if it is worth the $250 at waterfest.

Hello, I have a 2001 Passat with 2.8 ATQ engine and then I have this very nice AHA engine complete standing. The engine in the car has a broken valve and a broken piston. I was wondering if you guys know: besides the fuel injection, is there any other difference between those two engines...
