2.0 CDTI, EGR VALVE, MAP SENSOR AND THROTTLE BODY CLEAN

[Rusty2009]

Hi This is a great tutorial, will have a go at this in the week, made a massive difference to my H, I was going to blank off the EGR on the BiTurbo but have read it will cause problems, do I wait and do it when I get the DPF gutted and mapped out and get EGR mapped out too?
 
It’s on 23,000 miles what do you recommend doing and what problems do they suffer, I've had the 2009 SRi XP 1.9 H for 6 years and has only problem was bearing whine last year, but got all the bearing replaced before any damage set in, lucky and just missed the DPF so no problems there, EGR was blanked off at 36,000 and done a similar clean and the gunk in the throttle end was just crazy.
 
Hi to all new here and always find forums a great source of help.

It does help giving them a good clean.

Most people only advise gutting the DPF if you have issues with it.

I would hold fire on the DPF gut as new laws are coming out to test the DPF in an MOT.

There could be a way around it, get a spare ECU programmed and then mapped and a spare DPF this way way you can restore the car back to standard for MOT's etc.
