How To: EGR Valve / EGR Cooler Delete Mk5 TDI (BKD / BMN)

[Matto]

Andrew, mine went on the rollers at the last TDISport day couple of weeks back. Only averaged 200 over 3 runs. 216 on the Shark rollers when it was mapped. Chris said throttle response felt flat plus there was a dip in my power curve. For 200bhp it should hardly smoke, mine pummels so I believe there is room for improvements.

Ah right your going to be hard pushed to see anything over 210-215 though, As said above i think the RR under reads aswell

I had the Stage 2 (Made 216bhp) and Stage2+ (228bhp) map on my PD170

Stage 2 smoked but was still legal levels, Stage2+ was totally illegal

That long grub screw has a hole down the centre of its. Its in the kit to use for the boost gauge tap.

Great write up.

mine hardly smokes at all or so am told..be interesting to see what its like when I get it back from the tuners

Ahhh... So I shouldn't use it to blank off the vacuum hose then. Lol.

What do you normally block the vacuum hoses with?

Cheers!

There is usually a smaller grub screw which is sealed to go in there

That one is for the delete pipe.

Just use a grub screw without a hole down it.

Brilliant write up. You should do more of them!

I still think I'll be taking mine to Alex though......Far easier.

Fantastic fantastic FANTASTIC tutorial. Used this on my audi a3 8P BKD engine with the hand of my mate and managed to clean my valve out and the avd. I used Valvoline EGR cleaner (£7 incl next day p+p from ebay) and it worked perfectly. Disassembly was a b*tch!!!!!, cleaning was fine, reassemly was not bad.

Some stuff that were not pointed out in the tutorial were some hoses connected to the egr and maf pipe that needed to be taken off but they were no problem at all. I would also recommend taking off the cooler and this allowed alot of extra space and ten mins to take off. Also i recommend using a proper allen bolt kit with extenders and proper wrenches and standard allen  keys are a b*tch to use!

some have said that only cleaning the egr and avd will not show much of a difference in performance but i beg to differ. I say a change  in pickup, high torque on lower revs so really pleased for a job that cost me £7 to do.

Next job will be to clean the turbo vanes with the Mr Muscle trick as this is proven to help the performance of the car ALOt aswell as clean the turbo for only £4!!


This helped solve my P0401 error code.

Once again fantastic  thread!!!!

Awesome write up! I've realised I need/want a few extra bit's before I get mine fitted by a friend.

On the BMN engine isn't the EGR controlled by the ECU? I don't seem to have a vacuum pipe just a plug plugged into the side of the EGR valve. I'm a bit worried about what to do if I delete mine. I read it can send the car into limp home mode.

It is controlled by ECU on the BMN engine, I'm not 100% sure of the answer regarding limp mode.
Dark side Developments may be able to answer.
Alternatively, you could try unplugging the connector and see what happens, if you have the means to clear the fault code afterwards?

Yes it is. You will have to have it mapped out.

As @jason_rmh has just said you will get a fault code. I used to get one as it know it has been unplugged but was removed in the mapping I have.

Nice write up, thinking of doing this on my A3.
