Hello all,

Long time no visit from me. I'

Picked up a nice 2007 T5 2.5TDi 130bhp this weekend which I thought was a good buy having had £5100 worth of work in the last 18months at a VW specialist including new DMF and clutch, new turbo, new camshaft as well as lots of other work and also a remap is noted on the same receipt as the turbo job. It has 200k on it with full service history and was an ex VW demo then same owner 10 years.

When I went to pick it up I thought it sounded rougher than it should, it was -1 however and I noticed the thermostat is faulty so convinced my self it was just "cold diesel" noise. The person selling it commented it seems slow to pickup until 2000rpm and i agreed but generally it drove OK but was noisier than i expected. I thought it was a vibration from something but having had a proper look now home it sounds to me a bit like when the fuel pump timing is out. On the 4hour drive home it didn't seem much quicker than my old 1.9TDi T5. For a mapped 2.5 this clearly isn't right.

My concern here is that it had the camshaft done 8months ago and it has possibly been like this ever since.
Does anyone have a recommendation on where to start with it or of anyone who is really clued up within an hour perhaps of PE19 Cambridgeshire?

Could this be a bad remap perhaps? I am happy to have it retuned to stock as a starting point if anyone can help with this?

My BNZ does not pick up until about 1800RPM, it's just the way they are.
The 2.5s are a noisy engine as they are a clockwork, cog driven engine and have no belts to quieten things. This is why they have a 6 speed box to allow them not to rev as high.
It most definitely should be quicker than a 1.9TDi.
I am never keen on remaps especially on these engines as they are more than powerful enough. But if it had one done by a proper tuner their should be paperwork relating to this.
My guess is to have it set back to stock and the timing checked, which is a big job on these engines.
If the camshaft has been installed it needs specialist tools and needs someone that knows what they are doing.

If you manage to find a mechanic that is well versed in these engines look after him and shower them with gifts. As they are worth their weight in gold...

Hiya, thanks for the reply, I was reading your thread of your ongoing issues you had actually.
I have driven others and dont recall them being like this. Whilst I understand the 2.5 is not as "free revving" as say a 1.9TDi this one is like if you pull out of a round about thinking you could make it and don't slip the clutch to 1800 rpm you would get hit before you make it across the roundabout then it gets to 1800 picks up then 2200ish rpm it will go right up to 4000rpm feels completely wrong for a diesel and it's hard work.

I couldn't find my VAGCOM cable from years back so have a new one arriving at the weekend so will get it plugged in and see what the timings show as although its been years since i used VAGCom. Do you by any chance have any known good values? The camshaft was done on mine 9000 miles ago then 3000 miles ago it had new clutch, dmf turbo and it lists remap £300 on the same receipt but no detail

All very odd!

Thanks
Tom

So my VAGOM turned up and I am concerned at my torsion value. Does anyone know what it should be and what mine means?

Thanks

My AXE 2,5 engine is at -3.4. I don't think yours is that far out. That (Group 004) section of the German label file I have for the AXE says the range is -9 to +9.

004,4,Verdrehwinkel,,Sollwert: -9...+9 °KW

Edit - Can you post text of a complete VCDS scan here. Someone might notice something astray.

Thanks for the reply, much appreciated. Without sounding thick, it's been about 10years since I used VCDS until today, what do you mean by full scan (I have autoscan but it doesn't seem to work on my VCDS)

Cheers

A full scan should work on a pre-facelift, but it's slower and you need to enter your van's chassis type (easy to find from your VIN).

Facelift onwards, autoscan is quicker because VCDS can just read the modules that are actually installed from the CAN Gateway installation list - prior to that it has to try all of the modules that your van might have - which is slow because you have to wait for timeouts on the ones that aren't there.

Maybe your van is still a bit too early to use autoscan. You have to use the pull down menu near where the autoscan button is. Look out for 7H or 7J. As Triffic says it will keep looking for controllers your van doesn't have but it will get there in the end!

Thanks that seems to have done it, please see below :)

Thanks, think it has done it now I think you and Triffic were right.

so at idle -4.9 by 4krpm -2 occasionally -1.5 Torsion if that means anything to you guy

Also, under readiness i notice


Readiness Status: 00000000 00000110 10000000 10000000
MIL Status: MIL OFF
Comprehensive Components: Passed
Fuel System: Passed
Exhaust Gas Recirculation: Failed or Incomplete
Number of EOBD-related DTC(s): 0

When i got the van 10 days ago the thermostat was failed and it wasnt getting to temp.
Having replaced with a gen VW stat, fresh coolant and a full service with all filters and Castrol 507 spec oil (the expensive stuff) a tin of Liquid molly injector cleaner and a full tank of shell vpower diesl the van is definitely a lot quieter than when i got it.

Performance is also better once up to temp

I have a bill saying "repair DPF" £300 and "Perform Remap" £300

I wonder if things have been mapped out. I seem to still have a DPF (i think from looking) unless it is just casing.

There a few tell-tale signs that a BNZ DPF is working and regenerating-

It regenerates roughly every 300 - 500 miles depending on driving conditions.
At night the headlights dim briefly as regeneration starts, I assume due to the fans coming on.
The driving characteristics round town is a lagged but snatchy throttle response. ie, a brief pause, than BANG full throttle. Makes you feel like a learner driver with kangaroo fuel!
The turbo spool up time is virtually non existent.
When stopping the van, the engine runs very lumpy and juddery as it settles down to a normal idle. I think this is due to some of the extra fuel that is injected 30 degrees ATDC occasionally igniting in the cylinders, rather than passing through to the DPF.
The cooling fans run for 5 minutes after switching off the engine, to keep the engine bay cool.
A strong smell of burnt toast comes from the exhaust, and can be smelt in traffic.

In other words, it's really obvious when it's regenerating. The later 2.0 CR engines seem to regenerate without noticing anything.

Thanks bluezie, that sort of describes how mine is. What about this though, have I measured wrong or does anyone know if this is a sign of my DPF not being present?

That doesn't look right! The temperature sensors are showing nonsense, and figures like that should be throwing implausible signal codes for all 3 sensors.
Also there is no value for carbon mass, which as it turns out isn't the soot load, but the ash load. (seems to be a translation issue with the English label file)
Mine at 112.000 miles is showing 75, which is grammes of ash.

No fault codes at all other than the EGR above under reediness. I did briefly have a MAF sensor code and thought we had nailed the fault but then when looking at the mileage it logged the MAF implausible intermittent code, it was this week when we did the thermostat and had MAF unplugged to take airbox out and I think we had the engine on briefly with it unplugged as were working into the evening darkness . I have cleared the MAF code done 50miles since and it hasn't come back so think it was caused by us

MPG driven "fast" is 18mpg. Normal 22mpg and gently 29mpg. Seems to low to me
I have changed all filters inc air an fuel etc. It smells to me like it is overfueling. Really not sure what to do.

I wonder if the EGR valve is simply stuck open. It may have been gunged up anyway and now if they also mapped it out, it can't report properly accept under 'Readiness' which is an emissions test used mainly in the US. It's the smog test on the equivalent of our MOT. The EGR could cause easily cause occasional MAF codes and it can cause the engine to be harsh sounding, even the poor performance and fuel consumption too.

Using VCDS you can look for the EGR under 'Measuring Blocks'. You should see the duty cycle change as you blip the throttle. Make the MAF figures are moving normally too.

You can also try running 'Output Tests' in the engine controller with the engine at idle. It will run through various things and exercise them (N75 valve and others) when it gets to EGR you should hear the engine note change from harsh to smooth as it cycles from fully open to closed about once a second for about 15 seconds in total.

If you can't hear any engine note change or it won't do the test at all it's worth physically investigating the EGR. There are descriptions and pics on here and videos on youtube of how to take it off. :)

So we cannot hear any change in engine note. If I unplug the EGR we don't get any warning lights or fault codes in VCDS
The pipe to the EGR from back of engine is cold to the touch after a 20min drive (engine up to temp)

When we unplug it the actual value goes to zero and the duty cycle stays at 39%

When running output tests there is no change in engine note as it goes from off to on etc.

Pics with it connected

MAF seems to increase nicely with engine RPM
