i got my dp installed yesterday everything was good...the next day i start the car and there is a noise that sounds like a chain rattling, so i start driving and i get the service engine soon light and it says power reduced on the i drive. then i lower my window and i can hear the rattling sound from 1K rpm to 3k rmp. I was just wondering if anyone has had this problem and what it can be or did the mechanic put the pipes in wrong ?

[j|rz44]

you have them install them?

[BOOST3D]

no, it was a mechanic shop near my house they usually work on all my cars haven't had a problem w them

[j|rz44]

either your shop screwed up, or a cracked weld...
i would just take it straight to RR and have them check it out...

[Sneeze]

After my RR dp installed got a CEL and followed by SES and noticed that my exhaust was a bit louder, but that was it.

[BOOST3D]

the exhaust is louder but there is like a rattling noise from the front passenger side thats what worries me

[Supramano]

is the rattle during acceleration, deceleration, idle, or all of the above??

[hotrod2448]

Most likely the DP's rattling against each other or something else.

I also encounted that. However, mine's a RHD. Seems that one of the pipes is very close to a "wall" which cause the rattling sound. Went back to the workshop, and they put a thick piece of rubber from a hose in btw, so far, have not got any rattling for a week. My workshop have to take out a metal plate from the side as it was too close to fit back. I'm not sure if rest have similar problems on a LHD car.

sounds like an install issue... the chance of a weld breaking is slim to none.

Take it back to the shop you had install them. I have done over 10 installs on these and nothing has happend like you descibed......

just that no one can get traction anymore

If you would like you can always bring it to me and ill check it out... there is a certain way to postion the DP's or "clock" them when they are on the turbo... they will move the left and right a bit when you clamp them on the turbo before you tighten them...

let me know if you need help.

[boosted305]

regardless of the origin of the rattling sound, it is unrelated to your check engine light...from what I've read, you need to get Terry's o2 sims and you'll be fine...


regarding the rattling, that's got to be a simple install issue, take it back and have them look at it, I'm sure it can be fixed easily

[BOOST3D]

thanx everyone

[asdflkijd]

you should take it back to the shop and have them figure it out since they were the ones who did the install. gl, keep us posted.

[j|rz44]

you figure it out yet?

I can almost guarantee its the pipes hitting each other. Does it do it under moderate acceleration below 4k and <40mph by chance?

I am also having a similar problem. I had the RR DP's installed about a week ago and I'm now having a severe ticking sound coming from my engine bay. The research I've done from other e90 postings states the problem could be a wastegate issue. This will be a time consuming process if I have to remove my mods and bring the car into the dealership. Whats the chances of this rather then the DP's or heat shield of some sort touching? The ticking noise speeds up as the engine revs as well.

Thanks,

CEL and/or limp is normal. wait for riss racing's solution (their own sims) or get terry's o2 sims....

YoungBug...you may want to start another thread on this issue. Your's might be different.

[BOOST3D]

i didnt have time to take it to the shop im going to take it tomorrow its kind of like the problem that youngbuck is having its like a rattling or ticking noise but id say it sounds more like a bunch of little metals shaking

Check the heat shield, closest to the front passenger side. Sometimes this is loose and makes a metal on metal sound.

Fitment issues, most of the time, are when the mechanic (other than RR approved installers) tighten the top turbo clamp too tight when installing the actual catback. Make sure the turbo clamp is on loosely and install the catback, then tighten both.

also make sure the o2 sensors are installed in the correct pipes not switched or your ECU will get contradictory signals which would explain why it took a while to foul as it perpetually corrected in the opposite direction it was supposed to
