HELP - A4 B8 2.0 TDI - Particle Filter - Limp Home Mode :-(

[jamin128]

Hello everyone,

Please can someone help me.
I have read other threads on this, but I am getting confused!!!!

Click this bar to view the original image of 1024x576px.

I have VCDS, but quite little knowledge on how to use it.
I have tried doing a forced regen by following VCDS WiKi, but I keep getting messages like 'aborted safetey reasons' or 'not started'.

Please can some explain the process of a forced regen in lay-mans terms for an A4 B8.

Thank you in advance.

last time I did one I used the wiki guide and it worked for me

what fault codes showed up when you did the scan ?

 

[steve.askew]

yes get the code reader on it, hope you have P0473 or P0472. I had same issue on my A4 2.0 tdi and with your mileage at 82K can be quite common, i was lucky, mine was just the dpf sensor, a 10 minute swap out, but sensor was £60 was the stealers for the part

Just gonna do a scan, where is the sensor?

 

[jamin128]

I have the following:
P2463 00 [175] Excessive Soot Accumulation
P2452 00 [101] Elect Malfunction
P2453 00 [101] Implausable Signal

Not the sensor then I think, oops it is located top of engine, just behind the engine cover on the left side just before the firewall. But with those codes I'm sure it won't be ;( without looking might be a dpf clean and regen, anyone any ideas?

This is cheap isn't it?

Where is the sensor located?

 

[steve.askew]

it is lit at the very back of the engine, top side, against the fire wall, with an electrical connector on the side, and 2 rubber hoses at the bottom

The simplest thing to do is Google Audi G450 sensor location, i have just hopefully will help you out

It has never run so sweet, thank you so much everyone

Is it worth trying a forced regen?

What did you do to cure it?

 

[jamin128]

Replaced the DPF sensor.
