Problems after remap!!!!! Any help please

[447golf]

Have a chat with John Robins at DNA tuning, he has been absolutely fantastic with any problems I've had over the years, and he really knows his German stuff, and has the most insane tdi mk4 I have ever driven even kept up with his mental S8 on the twists and turns

sounds like a seal may of gone?

  

PMSL!!!

I would try the N75 valve mate had a similar problem with mine. What valve do you have fitted at the moment?

Right I scanned it and it came up with p1297 pressure drop between turbo and throttle valve. On auto data it showed me the waste gate regulating valve. But now I'm thinking the bailey dv30 is leaking. I'm not made of money so don't want buy bits they I don't need. I'm sure every understands this

17705/P1297/004759 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)

Possible Symptoms

Malfunction Indicator Light (MIL) ON
Power Loss
Possible Causes
Leaking Hoses and/or Pipes between Components
Boost Pressure Control Valve (N249) faulty
Diverter Valve faulty
Throttle Body dirty
Vacuum leak

Possible Solutions

Check Hoses and Pipes between Components
Check / Replace Boost Pressure Control Valve (N249)
Check / Replace Diverter Valve
Check / Clean Throttle Body
Perform Throttle Body Alignment (TBA)
Check for Vacuum leak(s) including PCV system
Special Notes
Did anyone install an extra (wrong) dump valve?

When found in the NAR 2.0T (BPY) check RVUTB: 01-09-03 or 2018919 for updated Crankcase Breather Valve
If the breather valve is faulty, full engine vacuum is typically found when removing the oil cap at idle.

Right changed DV back to standard one ran much better still a little hesitation but has thrown up P1200. N249 mechanical malfunction. Do I replace this or do a bypass on the N249???

[Wazzzer]

I'd bypass it if I had one

[2pthemarine77]

I am at my wits end now on the way home it went into limp mode 5psi (holds it constant). When I drove the car to work Tuesday morning it was perfect. That evening map man came to my garage and mapped it I've had nothing but problems since shall I just get him to put the original map back??

[447golf]

I would definately get him to put it back, but also get him to check if it already had been mapped, as that has caused me trouble in the past

[2pthemarine77]

He is coming back. To try a different map. Or put it back as it was, he is being as helpful as poss so can't complain. I'll let you know how it pans out.
