Hi there,

Can the following be diagnosed using VCDS measuring blocks?.
  1. fuel injectors
  2. catalyst converter
The car has failed MOT emissions test, confirmed symptoms that relate are (very slightly) slow cold start, occasional black soot debris from end tip and no engine fault codes?.

Vehicle: Audi A2 1.4 TDI 75 2004 BHC

MOT Smoke Test Results:
Plated Value = 1.49m-1 (fail) - Min 0.60 - Max 0.70 (pass)

That's a pretty old-school engine management.
I'm not sure it it has any way to self-check the oxidation catalyst
I guess I would start by looking at MVB 013 to see the injector balance.

Hi Cronus7,
What is the service history? Do you know if they got it hot enough? Might be worth taking it for an "Italian tune up" directly before the smoke test.

Hi HMC,

The service history is good, genuine oil and filters annually, cam belt water pump glow plugs etc at 102k and good quality fuels always used. Unfortunately that morning i forgot to drive it until up to temperature and so would have dropped it off cold 🙄. I have taken it for a few "Italian tune up" this week after adding some Stanadyne and filling the tank with premium. I will be taking it out again for a another "Italian tune up" before the retest.

Kindest Regards

Hi Uwe,

Would you possibly know why on this vehicle my vcds MVBs keep reading in German and not English?.

How about having mechanical injectors spray atomization pattern and drip/leak test done?


Timing mechanically verified yet?

JPPSG yet?


Is programming FOD?

Most likely because the MVB descriptions were not available in English.
