You probably just got two downpipes from seperate batches... It was made clear to me that AR has made some revisions along the way that had different fitments. I doubt your shop had intentions of damaging anything, they probably are trying to hep you out instead of making you have a down car for weeks at a time and paying to have it all installed/uninstalled again.. Don't try and make this the shops fault, the pipes don't fit.

why the hate for AR? can you find a legitimate thread or instance where ar design dp's didnt fit perfectly? i know i have installed countless of their dp's and never had even a slight fitment issue at all.

not the shop's fault? they dented a sensor that controls fueling to the computer to make an exhaust component fit its completely 100 % their fault, i dont see how you can look the other way on that and make your statement. put the stock dp's in if you dont thing they are gonna fit, you dont just damage other parts

Update: The good news is that the downpipes are in!

The bad news is that they had to relocate the bung on the "inner" downpipe (the one without an o2 sensor plugged in on the pics).

I asked them about the dented sensor. They said the upper part is just a hollow protection, as the sensor itself is located on the tip. I guess as long as they work I won't be able to talk them into replacing it

Anyway the car should be finished tomorrow evening. I keep my fingers crossed that all will be fine. Thanks for your help!!

good to hear, i have my fingers crossed for you.

i will post a pictures of my o2 sensors in a few minutes... yours definitely is damaged.

[cocoturkey]

this is what your o2 sensor should look like...

[Kevin@AKMotorwerk]

Visual inspection by itself is not usually sufficient to determine if an oxygen sensor is functioning correctly however, the lead wire and connector should be checked for damage. Any damage will interfere with the sensor signal. The sensor body should be checked for dents, which are a sign of mechanical shock that can crack the sensor element. Also, the appearance of the sensor's protection tube can give an indication of possible problems. Below are a few examples of damaged sensors and an indication of what might have been the possible cause. The cause should be rectified and the sensor changed to avoid further problems including damage to the catalytic converter.

wow sounds like some backyard redneck stuff they are doing i would get your car out of there before they weld on some glass packs and airbrush a big chevrolet logo on the side of your car.

What are you talking about? Where am I hating? I don't need to prove a thread to you about anything. I've been told personally, over the phone by someone who is well respected in the n54 community that builds turbos for our cars that he installed a set and there were two different pipes and they didn't fit. There are different revisions of the pipes that will fit as long as they are mated and installed together. If you get them mixed up there is an issue. Get off your vendor high horse I haven't made one stab at AR. You have obvious intentions acting like some supportive nice guy, and the reality is the opposite.

You can waste time and money installing/uninstalling pipes and having down time, or you can waste time and money replacing and installing an o2 sensor, and thats only if it happens to be broken. Which would you rather do? Either way he's out some money from some where might as well try to get it working and save him the down time. Point is, AR has made different sets of downpipes that will fit but not when the revisions are mixed up. Its either that, or the pipes plain flat out don't fit. My reasoning here is a positive one in light of the situation to say that yes ar's pipes fit but sometimes they won't fit if they get crossed up. Relax, god damn.

EDIT: No need to use scare tactics about the o2 sensor, I know what a flipping o2 sensor does ok? You're hilarious. If the pipes actually fit TOGETHER then the o2 sensor wouldn't need to be bent, can you comprehend that? If you can't see how better fitment = no need for trying to force a fit then you're IQ surely isn't very high. And whats the point of buying AR pipes just to put the stock ones on? And why would putting the stock pipes back on be an option when they supposedly ALWAYS fit? Which isn't true. The name of the turbo builder doesn't need to be named, its not ASR and its likely a very rare occurrence that a mismatch/misfit ever hapens which can be resolved by simply sending the right pipe out, but installation issues have happened they happen to every fabricator at some point. I think ar design will cop up to that. If he doesn't, then he's a liar.


EDIT2: BTW, You might wanna check your tire pressure because your tires keep you on the road and prevent you from swerving off the road through the gaurd rail off a cliff to a bloody bloody demise, then you're whole family will suffer and be poor and sad forever... Buy my tires!

Also, o2 sensor doesn't control the fuel. Its a sub-component that plays a role in the macro picture of the vehicles operation along with all of the other sensors like temperature and manifold pressure sensors. The o2 sensors provide an electrical signal to the DME which sends electrical signals to the injectors and fuel pump, thats what controls the fuel, the 'fuel system'... Not the part that this shop supposedly, 'ruined'. But oh the sensor is probably fine. So how is it 100% their fault? Quit taking your blame and throwing someone else under the bus. I guess you don't know that. o2 sensors control the fuel just as much as your catalytic converters do.

[TurboBimmer]

I bought the downpipes in a group buy last summer, but only now I've come around to have them installed (prefered to wait for warranty to expire). I'm not really blaming AR neither the shop (altough the dented sensor looks a bit like very "rustical" work...) as long as everything works tomorrow, though this episode will probably set me back another 200-300 bucks.

But the shop took the appropriate measure and relocated the bung to prevent more down time of the car.

I don't know what dog you have in this fight but just so you know, AR did have fitment issues for us righthand drive people. Just because we didn't post here does not mean AR Design never had issues. Klipseracer has a point.......there were revision changes made at some point and it got quite messy as many that had been shipped overseas had to be remade since the ones we received, became expensive paper weights. Now imagine if by mistake the OP was sent one of each (RHD/LHD) or since he is LHD..........what if he has wrongly been supplied RHD dp's and therefore a clash of sensors?

Making blanket statements like yours will certainly aggravate those that did have issues along with paying twice to have them fitted. Just because you have never come across an instance of install issues does not mean they don't or didn't exist.
In Andrews defense at AR Design......he handle it professionally and allowed us to sell the LHD dp's and re-supplied us with the correct ones for free. So all credit to him because his product is top notch.

if you go to my first post in this thread, my first question was if the car was left or right hand drive, simply because i was aware of the right hand drive fitment issues. i dont think i attacked anyone but the shop for purposely denting a sensor, no matter if the pipes are made wrong or the shop didnt install them properly, i dont feel they should have dented anything.

The simple fact that you know ar has had fitment issues in the past yet you indirectly yet directly make the insinuation that you've, "NEVER EVER EVER" had a fitment issue makes you a liar and a misleading vendor. Sad.

I can attest to this. I had issues with a few issues of AR pipes not fitting, but they were resolved by Andrew in very short order. Also everyone said VK pipes fit like crap, yet I think they were the best fitting pipes I ever put in an I model.

But back on topic..... I've squished the wire end on a few non bmws by accident in tight locations, and they have always worked. Now if you drop the sensor or slam it with something, then yea id replace it....you damaged the hot end of the sensor then you are bound to run into problems.

[MFKN3]

LHD is easy. RHD is where fitment can be tricky and AR are the only ones that I know of that fit.

Your problem however looks to simply be that someone has bent the sensor!

[Tiago@VRSF]

The bent part of that sensor looks fine. It looks like they bent it so they could try to fit the o2 sensors together without hitting.

To be honest the only person who could tell us how many AR pipes don't fit is Andrew and I doubt he'd ever post that information publication because it'd kill his sales. These are hand made parts, made by people. There are bound to be a few problems along the way.

[vasillalov]

Funny... My AR downpipes fit like a glove. The shop who installed them said that they have never installed downpipes that fir so well and they are a racing shop exclusively for BMWs.

Even though those parts are hand made, they are welded on a jig which pretty much eliminates any problems. I think that was just a mix-up and the OP received wrong pipes.

[Mike@N54Tuning.com]

I have never seen any fitment issues personally on LHD cars. To be honest and fair there have been some issues on RHD cars but to be realistic it is difficult to develop for a vesion you don't have access to. I know all the RHD issues have now been resolved and i know for a fact Andrew took care of the problem VERY fast and in a manner that was VERY satisfactory to the customers.

So to summarize now there are ZERO fitment issues on LHD and RHD cars. The initial fitment issues on RHD happened early in development of the pipes to that model due to several internal issues.

Fact is they did NOT fit, and the shop moved the bung a bit to make it happen. All in all I was charged almost 400 euro extra labour cost.
Additionally the dps now throw a CEL with the procede v4, which was just what I wanted to prevent by chosing the catted version
On a side note the AR oil cooler fits and works perfectly...

At this point you have 2 options:

1. Enable the Procede V4 CAN Clear option - (free)
2. Purchase BMS Downpipe Fix - $80 + shipping and install it in the ECU compartment. (I prefer this myself and it works great!)

Good luck
