Using the wrong oil will almost guarantee you get dangerous sludge build up which will eventually wreck the turbo. NB: Not all oils marked synthetic are true synthetics.
Some users have reported problems with early coil packs but most of these will have been replaced now and newer coil packs do not seem to have any problems. Fitting a blow off valve or dump valve can cause problems with the engine management as there is a loss of system pressure. The air flow sensor can become soiled particularly if you use a filter which is impregnated with oil.
Take off the air flow sensor and clean with a IPA based solvent if you notice any hesitation or problems that can be assigned to a faulty MAF. Please share this page with your friends on :.

Name required. Mail not published required. Your Constructive comments on this article. I build a auditt which we stroked to a 2. I am sitting with a huge problem in that the throttle closes itself under hard boost. Is there any way of solving this problem. On the dyno the car acts normal but on the road it starts having a mind of its own. It sounds like the car is going into limp home mode or the anti knock protection is kicking in.
I suspect you need better fuelling. Did you uprate the fuel pump and injectors? On the dyno the air intake is usually warmer therefore less oxygen is available on the open road the air intake is much cooler and it could just be the difference between the car running lean or not. Check the boost levels when this happens and see what happens to the fuelling. I run my car hard often and have had not problems with its performance.
And as soon as I get a second car to become my daily driver I will strip the TT down and build it up for time attacks while staying with the 1. He was right about that. Life fast and live free. The jerk is from too much boost at low RPMs.
I had the same problem with a stock 1. I had it worked on and they pinched the line to the waste gate and it was running full boost all the time. Hopes this helps. Almost destroyed engine. O-ring between oil filter flange and turbo oil cooler assembly dried out and leaked badly. Easy fix, and nothing but a cheap o-ring. Owners of older models Audis should replace this o-ring. Unit located where oil filter screws on, between the filter and the engine oil flange.
Thats right to the top line on the dipstick. If I put 4. U guys should check that! There would appear to be some differences between these engines across the range.
Perhaps the Transverse A4 1. Interested to know how the front control arm bushings held up to Champcar in your B5 Audi. I am building a 1. What codes are compatible with ATW? Can i use any engine code just as long as I get the ECU that comes with it?
Is there a reason for this? Also, are you certain that the connecting rods are forged? Forged components cannot be identified on the engine code alone, the year of manufacture also comes into play. Fantastic article in plain english: I have a 1.
We have heard of cheap import turbos suffering from premature failure, sadly the quality control and casting of these cheap imported turbos can often be far from ideal. Not that all are bad, but we would tend to source a local reconditioned one or used one with some kind of warranty. You do get what you pay for. Fantastic article, thanks for putting it together. I have a 1. Do you think this would require a turbo and clutch upgrade to retain reliability? The stock turbo is K03 on my unit.
Appreciate your input. The article says that engine puts out up to so hopefully my assumptions are correct! The only other question is whether, if I buy and install a Bluefin remap, Audi would know that I have done so use it for a bit and return to normal map before putting in for a service? Hi Just had my A4 1. What boost psi would it be running on this stage1 And should I preorder a clutch and if so would the TT clutch fit?
It has the AVJ lump in it with a aluminium forge type DV which I can change the spring, hence the question about boost pressure. I love it, power band from up and just keeps pulling!! Great info by the way and glad to know that my AVJ engine is a strong one. I have a A4 Quattro 1.
Can anyone help me with how to set the timing on both crankshaft and camshaft pulleys. Setting timing from scratch as if the belt broke. Where are the marks? The main timing mark is on the crank, then you need to find TDC and set the cams accordingly. Any thoughts. Have you checked the coilpacks? Hey there, I have a 1. Dont want to blow up my beloved 1. What components should I upgrade to stay safe? Fuel pump? Typically a broken thermostat, a faulty water pump, or blockage in the coolant.
There are other more exotic reasons. Thank you for this article. I have a bjx 1. I have read so many forums but not many talking about this engine code. May I ask if you would know if the Pistons are mahle. I know the weakest point of this engine is the rids. I have recently purchased a Garrett Gtr turbo from the nisaan s14 s Would you recommend I change the Rods for this application and would a tuning company remap my ecu to run such a turbo.
Would it not be easier just to put an aftermarket ecu for better tuning. The BJX does not appear to have forged pistons but my data on that is not conclusive as the part is not listed! If you are pushing power to the bhp mark then I would recommend forged pistons. An aftermarket ECU would give better control but costs more and is more complex to setup and the cars immobiliser runs through the ECU.
We managed to make hp on the dyno but then when adding more boost the mixture started to run richer which we couldnt understand. Any thoughts? Are you running an uprated air sensor? Is the turbo topping out before you get the potential boost? Is the wastegate leaking or an air intake pipe somewhere.
If you remove the air filter housing does it still run rich? What a brilliant read on the 1. Out of all the articles I have viewed, yours seem the most reliant, and I was looking for some help. There were good and not so good kw units, some had stronger internals than others.
My advise is to plan your mods and find the parts, then get the engine and wait for a good one. My A4 is 1. The turbine is k For example, 3 inch down pipe, 2. As long as you taper into the smaller size you should be fine, sudden steps cause turbulence which needs to be avoided, it depends on the engines power, but for most applications on this block a 2.
