Potential fault - GFB DV+

[Bernhard30]

Hi guys,

Recently fitted a GFB DV+..only just bought it from AKS so I guess it's the later version.
This was put in to replace a split diaphragm on my old version which was looked to be causing a check engine light. From memory the fault code PO277..'running too lean at idle'.

Bit of a strange question but does the DV+ work just like a standard DV and so would not prompt a CEL on the dashboard. As even with DV+ in use..the car lasted only about 20 miles before the engine light came on again..so the fault still exists..but wanted to check.

Feels a bit like a boost leak/air leak perhaps ..but just wanted to check from those with DV+ experience.

Cheers

DV+ should not cause an EML and would not cause a P0277 code, which is something to do with injector 6 (which we dont have!) I suspect you mean the P2187 code? Bank 1 too lean at idle?

You can occasionally get the code for a mechanical fault with the valve due to the way the DV+ works, but it would not put the EML on

Sounds like you still have a leak somewhere, as a fault DV wouldn't cause that error anyway.

Split in your turbo house around the connection point is my first guess

No worries mate!  Having a decent DV makes a big difference in these engines!

It definitely does mate

Thanks guys. Will check it.
Correction to my earlier question..my fault code was/is P2177.
