Should I be worried??

[olitaylor07]

I have a 2009 CR TDI 170 and was having a nosey using VDCS and found in engine, measuring block, group 13 think it was injectors that the first box when at idle was -23 second was 5 third was around 25 and can't remember what the fourth one was.

Surely this isn't right??

Is that 0.23 or 23?

As long as they're all a few percentage points from each other, you're ok.

Otherwise; injectors, leak via gasket or valve, or piston blow-by (doubt it).

Running ok?

No it definately said -23.

Yeah fine. What does the reading actually mean? What's the difference between -23 and +23.

M'off Chester Zoo today so will log it all properly when I get home and show you.

Panic over.

Just all the blocks after a run to Chester and back and it's -0.59, 0.4, 0.12 and 0.02.

Think that's acceptable. However block 075 (DPF) third digit has gone from 6 to 8 which means its 2% fuller. Wierd!

That makes a lot more sense.
Cool!
