E46 320d Decat

[Radyn]

Good day to all of you

Got a quote for decat this morning on my Bmw 2003 model 201365km on the clock.
Car have not have dacat yeath.

I did browse throught a few threads on the sight but there is still a few questions i cant find answer for so please help if you can

My questions

Question 1
Auto speed Blacheath R1100 I know the guy and the car must stand a day and half to finish.
Powerflow Bellville R1600. Car must come in the moring and would get I the same day.
Is it a big job and why such big cash diff??

Question 2
After Decat should you do softwere or could you only do decat??
If softwhere is needed where in Cape Town could it be done and what could I expect to pay more or less.

Ouestion 3
They say I will not get any faults or warning lights cause its diesel is that true???

Question 4
How would I know if the cat is clog up because the car have 201365km still pulls strong and get 6.1l/100km.

Question 5
Does the E46 320d have 2 or 3 or these boxes.
I know there is one on top close to turbo.
If there is 2 do both need replacement

Question 6
Last I read if you fit straight pype not efficient airflow will get through and is also no good is this true??

I bought the car 3 months ago and i thing its still std no mods decat swirl flaps or turbo have been done so i have to do it all

Well that’s about it wit all my question
Every 2 cents would be appreciated
Will take car next week or week after that depends on answer

Have a gr8 weekend

Q1 - Powerflow Bellville anytime for me. 3 of my previous vehicles were done there and Roddy knws his stuff.

Q5 - the 1st one is easy just check under your car. Jokes neh:tease:

I hope u come right:thumbs:

Q2 does your car have oxygen sensor then it will have to be disabled no need to do software but a tuner will need to disable the oxygen sensor.

Q3 Oxygen sensor will give warning light.

Q4 if its clogged you will need to drive a 40km plus minus route open road for it to go into cleaning cycle and it will clean it self.

Q5 Only need to replace the one before the turbo,

Q6 Why would it there is 330D's running with 76mm freeflow pipes on with no problems

Thanks alot Dippies now i have a lot more clarity.
The guy at Auto speed say the remove the piece where switch turned screw into and weld it onto the straight pype and screw sensor in again and i does not give any lights of faults

 

[Dippies]

ok so they do replace the oxygen sensor then :thinking:


To the tuners on the forum will this have an effect...........

I didn't have sensors in my 330d which is a 2003 but manufactured late 2001. I dont know if you have mid cats but you might as well get them removed as well. When my car was on the dyno after the cats were removed. I saw no smoke come out the back and at 414 000kms I'd say this tractors running great :rollsmile:
