Nice ; ) , what do you guys specialise in? I take it your site is still under construction.

Website is all to pot at the moment, but will be up soon 
Are speciality is Motronic, petrol turbos. We have developed a lot of custom features for ME7 based cars including map switch functionality - upto 5 maps with no additional hardware. We can do the very latest cars including 1.6 TDI and 1.2 TSI engines

Chutz1.
I was one of the first people ever to have a de-dpf on a Leon.
Custom-Code/JBS used my car as a dev car and can tell you that the issue appears to be with your map as you would not be getting a DPF light for faulty sensor. if it has been done properly you would be getting EML or flashing glow plug light if one of those sensors were faulty.

Jsat at the workshop now, we are removing one. I can see what you meant by blocking the pressure sensors. This isn't an issue but you don't need to do it. It isn't what is causing your issue, nor is it an issue with the pressure sensor.
Looks like it hasn't been done properly in the remap i'm afriad.

Hi all,
I think I have just started to recive the same issue.
I have had my 2007 FR leon done by JBS full exchaust DPF Removed and rear box and full remap cost mew an arm and aleg aroubnd 2 years ago.
The dpf light has came on twice now in two days. I had a mate link his odmc reader and it showed no fault codes as all even though the light was on. I have vag-com lead and software I tried to read the dtc codes but again none was shown. I was not sure on what area of vag com I neded to be attached to so i selected moror, and also komni, the JBJS sig came up but no fault codes.
Seeing its under warenty from JB i have contacted them about it and awaiting there reply.
In all the two years its never show a faul on the DPF as I also thought these would of been mapped out.
Thoughts anyone?

I had that problem! Went back to JBS and it was a pressure sensor. Mine was a older pressure sensor model. A new pressure sensor £45 ish pounds and an updated map loaded on the car and the car was fine. However, I had my map looked at another tuner and there was a fault code but no warning light on the dash. The fault code was related to the DPF as it was not properly mapped out!
Changed tuner and much happier now as the DPF is properly mapped out now!
More likely a pressure sensor. I am sure the sensors are still live on the JBS map.
I think the car has to be put to standard first to get readings
then a controlled regen to check the sensors
If the values dont got down then it is a faulty sensor.
Replace sensor
Drive until car notices that the values are in tolerance.
Put map on car.

will it harm the car driving it?
I have a 110 mile trip to do to get it back to JBS.
Or should i drive it when the light goes out?
Thanks

The light would not go out if it a sensor fault. As far as I can remember the car will try and regen but it cannot as I am guessing that part of the map had been disabled. If it cannot do it I think 2/3 times then the car will go into limp mode (Soft) You can drive the car but it has less power and cuts the revs to around 3000-3700 I cant remember but it was not fun to drive. Uphills are a nightmare.
It is more likely a pressure sensor! If you can get that changed then it will take time for that new sensor to see a reduction in the values.
I drove mine to JBS 1.5 hours away. It took nerves of steel!
Kinjamin
Does these sensors cost a lot. Make model and can i fit it myself. Once fitted should i be able to drive the car. And will it still need to go back to JBS
The pressure senders need adapting once fitted, also why would they try force regen on a Dpf that's not there?
Around £45 pounds. Its just a unplug and plug in as for as I can recall.
The car needs to be driven until the values are low enough not to trigger the sensor! I think Kev said something like it takes 7 or 8 switching on the engine for the values to be measured correctly!
Hope you get it sorted out!
Kinjamin
JBS did that not me! It was trying to get the values down to the correct levels? I think it was to see if the sensors were not working properly?
Kinjamin
Yeh I meant that, confirms what most people say about jbs I suppose regenerating a Dpf delete to see if the soot loading values go down.
Well JBS have now replied and said I need to replace the pressure sensor as this seems to the what the issue is. Basically unplug and plug a new one been quoted 34.99 "076 906 051A" Exhaust Temp Sensor.
JBS also said I need to use vag-com to measure the soot the sensor is picking up it should be 0 if it is then the sensor is working fine with the dpf delete mapping.
I have vag-com but to tell you the truth I am a little unsure on what I need to do to test the soot coming out of the exhaust and if it is working correctly then why by a new sensor? The DPF light is off at the moment but has done this twice already.
Would like to know how to measure the soot with VAG-Com I have version 1.4, 3, 50, 5.1
can anyone guild me I can hook it up to my laptop ok and it connects to the car ok. just not sure on what I need to select to read the soot readings.
Also to adapt a new sensor is that all it takes me to turn the engine off and on around 7-8 times nothing more ie: drive the car at certain speeds? or at ? revs

just had another replie from JBS saying the following.
I just in a spin on this now.
They have said that the regen process is removed from the ECU not the activation of the sensors. They leave them active and live.
If the content of the DPF ia appearing as 0 then the sensor is active and working.
If the reading is hihger then it is faulty and showing that the dpf has soot content.
The sensor once installed wont requier anything doing to it other than a test drive of the car to ensure the soot content within the ECU readings return to 0
It makes sense but also tells me that the sensors are not mapped out by JBS

hi did they connect your dpf senor back to the dpf after removal as with mine,just need to found out if it would work with out it begin connected,the electrics for it are but the pipes have been blocked and i get dpf light on every other week,but the other day went to liverpool and i connected the two pipes together and the dpf light stayed on until i returned and blocked them off again
it is possible to test the sensor via Vagcom/vcds measuring blocks while using a vacuum pump, then you know if you have a faulty sensor and they do need adapting when a new one is fitted.
