G450 - acceptable pressure difference
- Thread starter kuebk
- Start date
Is the exhaust system or engine controller modified or are you just looking for baseline information?
If this is baseline related that would depend on the vehicle in addition to the condition of downstream emissions control devices IMO. Assuming this vehicle is not modified (or broken) I would take a guess at live reading in the 1 to 10 mbar range but you may want to post the scan and a control module map at idle. We may have something similar here already Reference Scans and Maps of Non-Broken Cars

Sorry, I didn't put enough details in my last post.
Conditions:
- ECU is stock
- Exhaust is stock
- A3 2.0TDI CBBB
You are right, I'm getting 3-10 mbar reading at idle and IMO this is ok. What I would like to know is how high the pressure difference can be before the problems begin.
By problems I mean:
- the car is sluggish
- errors in ECU about insufficent DPF flow
Here is the autoscan:
Hope its clear right now, let me know if not.
Thanks.

Thanks.
Although it may be unrelated to this exact inquiry I looked through your prior posts yesterday and noticed that Uwe asked if the EDC software was up to date. I dug a bit and this EDC (03L 906 022 RB) had a few TPIs/Flash updates over the years. Those includes the following software Levels; 3134, 3615 (which is the current version) and lastly 6552 (which was a cooling function fan problem).
You might want to check out TPI 2024764/10 and have the EGR cooler and pipes checked for excessive carbon (restrictions) followed by the latest flash update which should bump that EDC to SW# 03L 997 021 G with SWL 0508 or higher.
I can't answer the specific question but the values would have to be different depending on the load, time since last regen, driving type, temp, etc. If that vehicle uses an EGR cooler (like our US models) and the EGR cooler, or any part of the exhaust emissions system, is restricted engine performance problems in addition to DPF faults wouldn't be unheard of.
I think this thread would receive more feedback in the Car Repair Support sub-forum.

Hello,
These are the values which I prefer to work with.
DPF new or loading up to 15%
engine at idle and operating temperature > 0-10 mbar
>1500/min > 5-20 mbar
>2000/min > 15-35 mbar
DPF loading up to 40-60% (regeneration required)
engine at idle and operating temperature
>1500/min > more than 50-80 mbar
>2000/min > more than 150 mbar
For excample, 2.0 l CR DPF loading 15%
at idle > 5 mbar
2100/min > 20 mbar
3100/min > 65 mbar
4000/min > 105 mbar
