PD170 Stuttering Problem Solved

[Georgel]

**** sake pal, wind your neck in. I was asking the question, how am I supposed to know what a squashed Astra is? I thought you were reffering the diesel would "squash" the Astra in performance. I know the Astra is quicker, I have a friend who's got one prove that to me...

Graph says that was run in 3rd gear?

nah the corsa just looks like a squished astra vxr, i bet the leon would be better on country lanes with the torque tho you should try different secenarios, cos i no the tdi get breathless really quick in a straight line, i was thinking this yesterday as i struggled to get past some idiot in his big bore mondeo on the a38. on a road where you physically cant do more 'motorway cruising' speeds i reckon the fr wouldnt have that many things to worry about

I Havent, last time i spoke to them they wanted me to come back and pay like 100+ to have it diagnosed, im guessing somebody took theres back

I Dont mind the sensitive throttle thats half the point of the WILD Map

Can you ask them if the update cuts power? as i dont want to loose anymore

Well a small update on the car situation the glow light is flashing now so indicates a engine an engine management light. EGR is sticking and valve is caked in sooty stuff so needs replacement! Spoken to JBS about the dpf light 9/10 times its is a pressure sensor so hopefully would cure the problems so far.

Also in the same conversation the updated remap is for the throttle sensitivity and should produce the same bhp? Not too sure but will get them to look at the car when the car is in to JBS and report back. If the car is still stuttering I can safely rule out the EGR and pressure sensor!

Fingers crossed!

Yep

He tried 2 gears, 4th and 3rd.

4th produced a max bhp of 197bhp

3rd produced 204bhp

Well another update! Spoken to the local Vw indy mechanic! EGR fixed first fault flashing coil light. Pressure switch/sensor replaced. Still DPF light on? . The indy mechanic wanted to reset the DPF light by going through through the process? Had not time to do that so will try on Monday... Bit scared about that!

There is another thing the Mechanic said that it could be a mapping error, Spoken to JBS about the issues. I live in Nottinghamshire and entertaining the fact that to drive to Chesterfield with the DPF light on was one of the options by them with I have discounted.
In my opinion is a laptop with software that one of their techies can come in and update the firmware in Newark! its only a drive for them with the cost of fuel.

I am against hiring a trailer to get the car over there to JBS and if the issues cannot be resolved that day having to come back to them again another expense!

JBS are going to contact the vw indy!. I did say that there are people in the car forums that are reading. I would be interested in the conversation from James and vw indy garage!

3 Day without car not happy so far!

JBS will be contacting me tomorrow after talking to the VW indy!

Any ideas anyone?

Whats stopping driving it up there out of interest? Or is it on principle?

I dont suppose its either! I think I am playing it safe! With the DPF light on must be on there for a reason. Cleared the flashing coil light due to sticky EGR valve. Pressure sensor/switch replaced so therefore either map wont allow a reset of the DPF or something could be wrong with the Map itself. I dont know but driving there with a DPF light which cannot be explained at the moment could cause more problems? In principle it could be my costs against theirs costs and which one would be cheaper? For me it would be for them to come and remap the car with the update to check whether it is the map that is the issue?

Fair comment. I would say you'd be very unlucky to damage the car with the dpf light, after all the dpf has been removed. You'd think it would be a software, but we could be wrong. Either way, if you are not wanting to drive the car to them out of principle, I'd be inclined to ring JBS and tell them you are more worried about permenant damage and insist they send someone to you! Good luck.

Thanks, Will wait for the outcome from the conversations between the VW indy between them! Maybe I am one of the unlucky ones 9/10 times is a sensor issue changed the sensor and it is not 1/10

Well been to JBS and yipee got the car working! After travelling over 24,000 miles with the DPF delete and Re-map without the car missing a beat the car had a problem and I took it to the nearest place to me a VAG independent garage. The garage had the diagnostic equipment and diagnose the problem as a pressure sensor failure. After installation the garage could not turn off the warning lights! After several phone calls between JBS and the VAG specialist, it was made clear that the VAG garage certainly did not have the expertise and technical know how as JBS.

I asked the VAG garage to install the old part and took the car to JBS!

After a long journey in Limp mode! I made it. Kev was the technician looking after the car. He plugged the laptop in and then checked the fault codes. Immediately he identified the car having a pressure sensor failure and this was his gut feeling. He put the car back to standard and checked the fault codes again and explained the technical issues with great efficiently i.e I understood what Kev was on about. He said that he was going to forced the car to do a controlled forced re-gen and took the car out to make sure that it was the sensor and that the figures will decrease. He took the car out and sure enough the figure on the sensor decreased but now was reading a steady amount but was not reading correctly.

Another problem was that the bonnet realise somehow had got stuck and we could not get the bonnet open. Kev started managed to release the bonnet and noticed that the cable had loosened itself from the extension joint the cover from the joint it seems had been pulled open? Kev then fixed the issue and with a cable tie ensured that this cover cannot easily be pulled open and to try to stop this from happening again.

Kev did say that the pressure sensor was an old style one and the one he had in stock was of a newer type! Pressure sensor done, Bonnet fixed and Kev checked the figures with the new sensor and sure enough they were low enough for no warning lights.

A new updated map was mapped free of charge and another test drive from Kev and I was on my way again. The best thing about this is that even if the VAG garage had tried to regenerate when the JBS map is on the car they could not and therefore JBS had built in a fail safe to ensure that the car can never regenerate which cause some serious issues!.

Kev did explain that the newer map had the same power output but the throttle response has changed slightly. The newer map on the car is brilliant and smooth and throttle response is progressive which is a lot different to the WILD map I had. What a bonus! The throttle response is good where as before I lightly pressed 1/4 of the throttle and the car will go however when I pressed my foot down further there was not a second wave of power! With this map you can target the amount of power 1/4 then 1/2 the car will go quicker! It is smoother and I can feel at the moment no loss in power! May have to get the car Dynoed again to check! Any cheap rolling road places anyone?

I had a pressure sensor go after my deDPF a bit back.

 

[Georgel]

I've got a exhaust temp sensor down on mine. Smoke anyone?

 

[kilner]

no offence to any one with a jbs map but they are crap

i got a new stage2 map and it pisses all over astra vxrs

so glad i got rid of my jbs and found a beter tuner than was willing to do everything i wanted

carnt post the name on this forum as my post will just get removed but if you go on tdisport.com its all ther

btw im runing a golf gt tdi 170 and that weighs more than the leon this test was done uphill and the vxr had a run on me aswell so i had lost ground to make up and still had him


JBS are just so secretive about everything and they dont even want to talk to you about things so u neva rly no how your car is setup i prefer it all custom made how it should be

 

[Georgel]

My Sha rk map is good, but there's no way its quicker than a Astra VXR. I've got to go back to see him next week anyway, so i'll ask about a boost increase. That said I may already be running 1.64 bar??..

 

[kilner]

Eventually got around to getting RR'd again. Went to a local place near me.

Not impressed with the result to be honest. On JBS rollers it made 222.8bhp and 342lbft of torque.

Today it made 204.1bhp and around 292lbft or torque which is piss poor.

One thing in my defense is that a Corsa VXR was on the rollers before me (been remapped else where) and only made 192bhp (which is roughly the standard value).

So question is is my result correct or was the Dyno just way out.

I cannot quite decide as when playing with 200bhp cars my car doesnt go whizzing past them and it quite a struggle to get past some 200bhp cars. OR was the dyno reading around 20ish bhp below what it should be.

I am tending to go with the latter one.

Any how here is my graph:

btw runing teh car in 3rd gear is no good at all as it wont be on full boost jbs dyno ther cars in 5th and ther is a lot of speak from tuners about the ecu in these things u need to go and hav it done in 5th gear aparantly the ecu cuts fueling in any other lower gear than 5th

so that why wen all us pd170 people hav our dynos done were making from 201 to 204 but neva more but every one has run in 4th gear apart from at jbs who run in 5th

next tiem i get on teh dyno ill ask for a 4th and 5th comparison

also one of the fastest dervs at gti internationals the skoda octavia only made 204 bhp on the dyno but yet the times showed it was more than 204 bhp

i dont no why but this car just dosent work on the dyno

you coudl be all i no is i won a astra vxr uphill last night kinda suprised tbh

but i do hav the full milltek not convinced with this exhaust tho but still gota be beter than stock

o just to add i did take my intake manifold off and clean all the egr crap out aswell n i also hav the egr delete

mayb it was just a thrashed vxr or mayb it was just a vxr replica ??

im sure it was the real thing tho

 

[AndyVTR]

Or he wasn't trying.

 

[kilner]

deDPF?

the whole package is crap if ur wanting massive power

jbs is good if u no nothing about cars and your not wanting to no anything about ur car and u need a new dpf filter

its cheaper just to go ther drop ur car off and get a stage 2 dpf delete u will feel more power and also hav rid of the dpf at an ok price wen u consider a new dpf

other than that i wouldent let them near anything else of mine especially wen u pay 60 pouund to hav your car on the dyno coss they dident dyno it wen u hav the dpf delete and then you arn tabel to watch your car on the dyno complete joke

and i belive they are doin a dyno fix on people just editing old dyno sheets with your info and givin u a random print out i kno thsi is teh case for people that just drop ther car off and pick it up

hell i bet i can post my jbs print out of 222 bhp and it will be identical to sum1 elses
