Here is a quick guide on regenerate DPF for VAG vehicles with VAS 5054A scanner and some frequently asked questions about this regeneration:
Supported vehicle type: 1Zxx4x (Octavia II 2.0l/103 kW)
1Zxx5x (Octavia II 1.9l/77 kW)
1Zxx9x (Octavia II 2.0l/125 kW)
3Uxx5x (Superb 2.0l/103 kW)
Fault: Recommended procedure for the detection of saturation and recovery DPF.
Solution workshop: Detection of saturation: Vehicle self diagnostics.
01 – Engine electronics
11 – Block of measured values
Block 75, displayed field 3
The saturation value is given in percent.
Saturation limit values: 1) up to 75% - the recovery is carried out during driving by engine control unit itself; 2) over 75% - the recovery carried out using the VAS 5054A diagnostic devices.
- speed over 60 kmph;
- engine speed 1800–2500 rpm;
- enter 15 Access right, Coding 2 function number 21295;
- watch the measured value block 75 field 3, the saturation value has to be dropped to 15%;
- the whole procedure takes 10 to 15 min.
Some questions and answers that may help about DPF regen:
Question: The glow plug symbol is flashing. Why? What should be done?
Answer: The DPF regeneration has not been completed during normal driving and now DPF has reached its maximum saturation at which it can still be regenerated. The limit value depends on variant and Model Year, but is in the range of 105% - 125%.Possible causes for this are:
a.) Frequent short distance journeys, i.e. high soot loading while at the same time regeneration of the DPF does not take place because the conditions necessary were not fulfilled.
interrupted regenerations, i.e. the engine was switched off during regeneration. Applies to short journey drivers who have at least fulfilled the conditions for triggering regeneration. If the glow plug light flashes, the vehicle
a.) Engine running since start for longer than 2 minutes.
b.) Calculated saturation higher than 80%.
c.) Coolant temperature over 70°C for at least 2 minutes.
d.) No DPF-relevant faults stored in system.
e.) A defined vehicle speed
threshold must have been exceeded (e.g. for >80% loading, 100 km/h)
Question: Under what conditions is regeneration interrupted/ended once it has started?
Answer: Normally when regeneration has been successfully completed, or:
a.) After a maximum regeneration time (20 - 25 min.).
b.) If the engine is switched off or has stalled.
c.) If the engine is left idling for along time (5 - 10 min.).
d.) If 1000°C is detected by the exhaust temperature sensor.
e.) If during regeneration, a fault is detection the components relevant for combustion (injection/intake system).
If the regeneration is interrupted once started but before it has been 50% completed, the glow plug lamp flashes on the next engine start (cold or hot) and regeneration begins again once the operating conditions have been fulfilled.
How does regeneration affect the oil life?
Answer: On each regeneration or attempted regeneration, a certain diesel fuel amount is injected into the engine oil which reduces the oil life. If the "INSP" light in the instrument cluster comes on, the engine oil is exhausted and must be changed. Failure to do so could damage the engine.
I have no affiliation with the suppliers of this product, just a customer!
I already own an Autel DS708 but was thinking about buying a portable code reader, an OBD-to-Phone device. I bought one of the cheap ELM327 WIFI scanners so I can do diagnosis wherever I go. For only €11.00 I was sure this would be read only. The tool arrived last week and worked better than I expected. Now I would do a quick review on it.
Ordering and delivery: Ordered this from China on Nov. 21, payment made thru Paypal. The tool was shipped within 24 hours and arrived at my door 12 days later. The seller sent an email when order Received, Processed and Shipped.
Package: It came with a mini CD that contains software. Both the tool and the CD were in good shape.
Installation: The only thing I do not like is there was no manual or guide on how to use the ELM327. This is a WIFI device and I am supposed to build WiFi network between my iPhone and the tool. I sent the seller an email, and it gave me a link which was very helpful:
User experience: Once I followed the link and built WiFi network, I was able to read data from my car. No license required. I reprogrammed a couple of options - works great. Below are some pics of my cars info from the scanner: Hi guys, I just want to share what I did today. I ordered an OBDII ELM327 scanner off EOBD2.FR to pair with my iPhone 5 and just got it this morning. Overall I am very happy with the product. Tested it on my 07 Accord LX V6 straight away and everything went well. I only use it with my Accord, but theoretically you can use it with any OBDII compatible vehicle. I know some people have this to pull codes from Toyota, BMW and even Porsche. The one I got is a WIFI version and that will work with both Android and IOS system. For me, ELM327 WIFI is just fine. Anyways I highly recommend this product! It is also very fun to use. If you have a check engine light, this will be your friend. It can read an erase trouble codes and much more. Hope it can help someone. Here is the link:
Here are some pictures of how it works
I have not tried it on other devices except my phone, but according to the manual book, it should be able to work on iPad and iMac. If you do not have an IOS device, there are other options – ELM327 with Bluetooth or USB.

Land Rover Freelander 2-(2.21 only) DPF diesel automatic
Vehicle identification number VIN: 001002x
The car feel like it has no power. The dashboard indicates: “reduced engine performance” message and?DTC?P0234-00 error code stored.
JLR Mangoose SDD Pro
P0234 is a common untested DTC’s. It may caused by following reason:
1. Brake torque (brake on and throttle at wide open
2. Transmission oil temperature (TOT) exceeds calibrated threshold
3. Engine over temperature
4. Ignition misfir
Install V145 diagnostic software and perform a pre-diagnostic on the system (scan all vehicle’s ECU). Print out the system fault finding log. Connect Renault CAN CLIP diagnostic tool with vehicle via OBD socket. Read the faults present.
SC002 Enter Injector Codes command is performed after replacing the injectors, and only if the vehicle is configured with IMA (ET104 "Exploitation of injector codes" to "YES"). If this command is not performed, DF276 "Learning injector codes" error code will be present. (You can refer to the Renault CAN Clip manual or Renault after sales service for the error fault finding list)
Q and J letters and 0 and 9 numbers are not used in the IMA codification. Any enter codes with one of these characters will be invalid. The n°1 cylinder the cylinder located at flywheel side.
Step by step procedure:
1) Raise the alphanumeric codes to 6 characters engraved on the upper body of the injectors
2) Select the cylinder number involved in the "Desired" column, and validate it.
3) Enter the code injector pointed to the associated cylinder.
4) Fill the new codes for each cylinder, and validate.
5) Once the SC002 Enter Injector Codes comman
