I know this is a response late to the party but this came up whilst I was doing some googling into DPfs. I have a similar app for my 330d as wanted to see what goes on regarding regeneration as I always use additives in the diesel fuel so wanted to see if they actually work. I use the oilem hybrogen at the moment (have used Archoil and Hydra products to but not tested those through the app yet). I always use tesco diesel as its the cheapest near me so used this with the hybrogen. I do long runs every week (Anglesey and back around 145miles each way). Having monitored the dpf cycle, i managed to get 315 miles before it regenerated. On my next fill up, I decided to try the tesco version of the Vpower diesel to see if this makes any difference (with hybrogen). Having driven back yesterday afternoon and having the app monitoring the whole way I can confirm the mileage since the last regeneration is way higher at 450miles (and still climbing) which could be a good indication that the premium diesel does actually make a difference. Must stress all driving habits are the same on each test, eco mode 99% of the journey with the odd flick into comfort for an overtake. I would encourage others to try a thankful and see what results they get.

The code on the original O2 sensor was 036906262G and that is now back on the car and from which the readings above are based. The new one had this part number as a OEM equivalent but ran really bad when fitted, chuntering on idle and bellowing unburnt fuel when it hot with a AFR stuck at 17.63% :-(

The app I have shows live readings. The AFR seems to hover pretty much around the 14.7 magic number but does fluctuate during acceleration/lift off. Is there any way particular numbers I need to look for, i.e an acceptable range for both front/rear sensors? The flap in the air box was stuck in the closed position when I looked so that's a bonus. Attached some screen shots from app.

Ooh right ok thanks for that, I might put some new waterproof connectors on the there just incase it's causing any issues.

Hi all thanks for the responses. Regards the spark plug, it wasn't exactly loose but it would turn about half a turn to tighten it (tried as spotted the oil). These haven't been changed for many years so has been like this for a while. The coils are the per-plug version as opposed to 1 single unit or a 4-in-1 unit type. While I remember, I noticed that the 2 plugs under the 02 sensor connection (where it locates into a bracket on the gearbox) looked very worse for wear and brittle from either age or exhaust heat, what do these 2 connections drive? Could be causing my issues maybe? Thanks in advance

Not to bad to be honest, one plug wasn't fully home so there was a slight pool of oil at the bottom of the plug hole but certainly not bad by any means

I did wonder but it's never thrown a code up?

Ooh also ran some carb cleaner through the injectors

Hi All, New to the forum since i thought i might be able to tap into some excellent minds . My in laws Fabia has been playing up and so i thought i would have a bash and try and fix it as i have been dabbling with cars for 20 years or so and they cant really afford to throw money at it. Symptom: The car on light throttle kangaroos quite badly and has no power under hard acceleration. Very sluggish to pull away and sometimes revs can drop at idle I brought a iCar Pro and used one of the better Apps via my Android phone. The car has had various codes pop up P0106, P0170, P0172. The car has had the following fitted/changed; New cambelt/water pump (all correct and needed doing as was in a bad state) EGR Valve Plugs Genuine fuel filter MAP Sensor Air filter Coolant temp sensor Thermostat All breather pipes cleaned/checked. new servo pipe as the 1 way valve had stopped working. Throttle body is clean as a whistle I brought a new o2 sensor but it ran like an absolute pig throwing out black smoke so put the original one back in and ran fine (apart from the issue above obviously) Compression tested all cylinders and all read 200PSI. The above parts were relatively cheap so thought start with those over buying more expensive parts. The car sounds as sweet as a nut on tick over but there is clearly something not right. I get the following errors from the App but no idea what they relate to; Manufacturer defined - Monitor ID (MID) $06 - Component ID $46 Rich to Lean sensor Switch time - Monitor ID (MID) $06 - Component ID $14 Lean to Rich sensor threshold voltage (constant) - Monitor ID (MID) $06 - Component ID $7F Manufacturer defined - Monitor ID (MID) $02 - Component ID $46 Manufacturer defined - Monitor ID (MID) $06 - Component ID $46 Rich to Lean sensor threshold voltage (constant) - Monitor ID (MID) $02 - Component ID $3E Rich to Lean sensor threshold voltage (constant) - Monitor ID (MID) $02 - Component ID $3D The car does not currently throw up any DTCs. Have given it a good old italian tune also (as they only potter about in it) with some super unleaded and some Hydra injector additive. Any thoughts would be greatly received before i decide to suggest they get rid or scrap it. Regards Chris
