Hello guys,
first of all - thanks for such robust and quality product. Sleek design and speedy workflow on Hex V2 is simply amazing.
On the other hand, I have a lasting problem with my car and hopefully, we could find an area for discussion. Started with EVAP problem, and now finishing with air intake, lean system and EVAP is back again.

I have Audi A5, 2014 2.0TFSI quattro, 162kw.

Recent repairs
Well, it all started somewhat back in April. EVAP P0441 incorrrect flow appeared. All parts were changed into new OEM, except Vapor Canister, swapped it from a used car. From that point:
1. Changed Evap Purge Valve
2. Changed Secondary Air Injection Pump Hose with Vapor Canister Filter (was bulbing at the top of the rear driver side)
3. Changed Vapor Canister with pressure switch.
All these changes didn't helped to get rid of the incorrect flow issue. Accordingly, I registered at Audi to solve the problem.
1. They inspected the system and changed Vacuum System Purge Valve with Hose Set.
2. Updated ECU as there was a new software version from Audi.
Now that seemed to solve the problem at that point, for one day. After that, I started getting three more faults:
Accordingly, here is what we did further:
And after some time, old good friend EVAP appeared again.
4219 - EVAP Emission Control Sys
P0441 00 [096] - Incorrect Flow
Specific issues
What I started getting with these errors:
Next steps
Audi offers me to change Vapor canister pressure switch and see whether it solves the issue. On the other hand, I already changed some working parts which in fact didn't solved the issue. Accordingly, I am looking for any other possible ways this could be INSPECTED FIRST, before changing parts.
If I run Tank Ventilation Test in basic settings, it ends as Not OK.
Any suggestion is highly appreciated! Thank you up front for any help!

Recent repairs
Well, it all started somewhat back in April. EVAP P0441 incorrrect flow appeared. All parts were changed into new OEM, except Vapor Canister, swapped it from a used car. From that point:
1. Changed Evap Purge Valve
2. Changed Secondary Air Injection Pump Hose with Vapor Canister Filter (was bulbing at the top of the rear driver side)
3. Changed Vapor Canister with pressure switch.
All these changes didn't helped to get rid of the incorrect flow issue. Accordingly, I registered at Audi to solve the problem.
1. They inspected the system and changed Vacuum System Purge Valve with Hose Set.
2. Updated ECU as there was a new software version from Audi.
Now that seemed to solve the problem at that point, for one day. After that, I started getting three more faults:
Code:
5646 - Leak in Air Intake System
P2279 00 [237]
4105 - Bank 1; System too Lean at Idle
P2187 00 [101]
4007 - Idle Control System RPM
P0507 00 [038] - Higher than Expected.
Accordingly, here is what we did further:
- Changed PCV valve (didn't helped)
- Audi inspected all the possible components for vacuum leak - everything seems tight.
And after some time, old good friend EVAP appeared again.
4219 - EVAP Emission Control Sys
P0441 00 [096] - Incorrect Flow
Specific issues
What I started getting with these errors:
- Idle jumping from 650 to 950rpm with clima off
- When rpm sets in place, car shakes a bit, doesn't run perfectly smooth, even through rpm's are at one point.
- After filling a full tank, I need to spin on the starter for a few times in order to start the car for a first time. Further - no problems.
- System is running lean. Not 100% sure I am looking at the right values on UDS, but here they are:
Next steps
Audi offers me to change Vapor canister pressure switch and see whether it solves the issue. On the other hand, I already changed some working parts which in fact didn't solved the issue. Accordingly, I am looking for any other possible ways this could be INSPECTED FIRST, before changing parts.
If I run Tank Ventilation Test in basic settings, it ends as Not OK.
- If it is EVAP causing this Leak in Air Intake and Lean at Idle, I am not sure where to dig further... Any ideas?
- Can it be failing oxygen sensors? Is there any chance to read their values and inspect the problem from them?
- Intake manifold?
- Fuel injectors?
- Somehow clogged/squeezed fuel lines at the top of the fuel tank?
- MAF? Tested it by running full throttle and values were in described range.
Any suggestion is highly appreciated! Thank you up front for any help!
