After following advice on this thread I started a couple of weeks back, I got my Carbonio, Milltek decat, and Milltek system fitted then headed off to Jabba last Friday as I'd blagged my way onto the Briskoda group buy.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" /><o:p></o:p>

After sitting patiently for a couple of hours Michael came up to the very comfy waiting room and told me he'd got 174 bhp and 320lb/ft from my PD115. I know the consensus of opinion is that the Jabba rollers over read somewhat, but I was happy at this figure as I saw a while ago someone on here got 163 on Jabba's rollers after their custom remap. He asked me how much smoke I minded and I said at those sort of figures I could deal with kicking a lil smoke out!<o:p></o:p>

Ear to ear grin, I headed back up north and the car felt like it had been transformed!<o:p></o:p>

When I got home decided to take my friend out for a spin, and on the 12 mile journey to Matlock from Chesterfield, I booted my car up slack hill which is a yardstick for my really as I drive up this slog of a hill everyday. Pulling strongly to the top at hitting 100 near the brow (usually hold about 85 up this hill - its steep) I was well chuffed until my car went into limp mode [:(]<o:p></o:p>

Spoke to Jabba and after letting the car cool down a little she was out of limp mode and driving again, but not pulling quite as strong as before.<o:p></o:p>

Drove back to <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:eek:ffice:smarttags" /><st1:City><st1:place>Chesterfield</st1:place></st1:City> and got my laptop out, Vag-Com gives the following error in the engine module:
17965 - Charge Pressure Control: Positive Deviation
P1577 - 35-10 - - - Intermittent

During the journey hame I noticed that I am kicking not jus a lil, but a hell of a lot of smoke out (was raingin on way back from Peterborough so couldnt see it for the spray)

I called Jabba back and gave Michael this error code, and he suspects that the adjuster ring for the vanes in the turbo may be stuck with the 'shit that may have blown free due to extra boost' and is causing the turbo to over spool and putting her in limp mode. In turn they advised that I should have the turbo stripped and cleaned.<o:p></o:p>

Not questioning Jabba's integrity, but not being naive enough to jus blindly accept the first thing I'm told that carrys a very hefty price tag.... Has anyone had a similar experience, and what was the cause/remedy for you?<o:p></o:p>

That sounds like it could be a boost leak. It might just be due to more boost putting more stress on your hoses.

Does it come back after every time your car boosts now?

By come back do you mean the problem or the power?

Under normal driving it seems OK, however does feel slightly flatter than it first did.

If I boot it up the same hill, it'll go into limp mode again at the top until I turn the engine off for a while.

Iv had a look around and cant see any hoses hanging off or hear anything that sounds likea pressure leak, but Im not an expert [:S]

By come back - I meant the fault codes.

Clear the codes, run the car on boost, but not up your hill. Do they come back?

Split hoses are usually around where the jubille clips are tightened or at the seams in hoses.

I'm stuck with my company pool car at the mo, so will try clearing the codes on Thursday when I get her back and see if they're regenerated.

Does anyone have any pics of where I should pay close attention in the engine bay for splits? Would a split hose cause the engine to go into limp mode?

Anyone any other thoughts on the matter?

If it goes into limp mode every time on the hill then in my opinion it's the map. I've seen this several times with cars that have had a custom remap at Jabba. The problem is due to the car being setup on Jabba's inertia rolling road, it doesn't present a real road load and load is how VAG ecu's decide how much boost to run. So when you drive the car up the hill the ecu 'sees' a bigger load than it ever did on the inertia RR so ups the boost way more than it should and goes into limp mode.

BTW if you live in Chesterfield why drive all the way to Peterborough for a remap when JBS are on your doorstep?

I agree - but if it is doing it every time you get any boost now (that is why I told him not to go up the hill) - it is more than likely a leak.

My car is going into limp home when under load so I will be interested to see what you find.  High amount of exhaust fumes lends itself to a split hose - not enough air into the mixture so, ineffect, it is running too rich.

Okay getting a little concerened as i am meant to be going to jabba to get my 130 bora mapped and i was torn between a superchip and jabba so am i still making the right choice as i really dont want these kind of problems.

Any good remap work must be rr and road tested before handing the car to the client in order to prevent this kind of situation. It sounds like deffo a remap issue, just let Jabba take out a bit of boost from the remap, before proceding to other possible causes...

FYI, you should discount ~10% of the jabba rollers figures in order to get a decent estimate of your car's output.

I shouldnt take the problem Im having with my map as a yardstick for measuring Jabba's ability, as there are many members here that are happy Jabba customers from what I read . This was my reason for giving them a try. I dont know if the car was road tested before handing me the keys back, as if any of you have been to Jabbasport wll know you can't actually wait in the bay where the remap/RR is done. I assume that this will have been done as matter of course. Michael has said that I could have the map pulled back a little, and this would be a workaround, however he sounded pretty confident that with a strip/rebuild of the turbo I should be able to maintain the boost levels under load with the current map.

Baffled? I am...

They do a road test but it's only very brief and as you'll have seen Crowland is very flat. The problems are usually more apparent on hills or at higher speeds when the engine is more heavily loaded. BTW I previously had a Jabba remap and the fault with it was more obvious when travelling up hill.

Jon,

Although it has already been pointed out that it could be the map, Jabba's suggestion is definately possible. I know from speaking to my local specialist this is a very common problem on the lower bhp tdi's.

Chief,
Is he in a agreement that this could cause the excessive smoke too? sounds logical to me, jus want as much input as possible before I commit to the labour charge associated with the strip/rebuild.

Is it fair to say that pulling the map back is essentially just a workaround, and this adjustment ring being stuck will be affecting the efficiency/reliablilty of the turbo anyway?

I want to take as many things out the loop as possible before going down either route. If its performance vs $$$ thats gutting as I thought Id jus got a pretty good bargain! So where do I start looking for leaks on turbo pipes, and to I need a ramp and to take the splash guard out? [:s]

Eddy,
What was the remedy for your car? Did u have to have ur turbo rebuilt?
Saw your car down a JBS a few months back btw m8, tis nice [Y]

Why not get Jabba to do it, then if it stills happens afterwards get them to rewrite your map and don't pay for the turbo work?

What happens is the turbo gets clogged up and spins up slow, the ecu will try and compensate by throwing more boost at it while this is happening it free's off and then overboosts. You could workaround it but the problem will just get worse and worse. People have worked around it using diodes etc but its not safe. I'd deffo take it back to jabba.

I agree with thechief, get Jabba to sort it out. The problem wasn't there before the remap so it makes sense they should be able to sort it. However if they tell you it is the turbo how will you know it really is? Also it's a long way to travel.

The Jabba map was on my Golf and there was nothing wrong with the turbo, Jabba didn't offer to sort the map so I eventually by-passed the boost tables in the ECU by fitting a manual boost controller. Worked fine after that but meant I'd wasted my time and money on the remap as I was effectively bypassing it.

Most folks on Briskoda who get the limp mode problem after a Jabba remap are asked to return for the map tweaking, a bit inconvenient when some people travel quite a distance due to Jabba's reputation and figures.

Anyway hope you get it sorted without too much grief or expense. Before paying out for the turbo looking at I'd suggest you take some logs of the boost with vagcom to see what the ECU is requesting and what the turbo is delivering.

Cos they aren't liars at Jabba, despite what you think Eddy!!

Lets not forget the problem you had after jabba did your car was well documented on this forum as being there before you went there.........?!?!

Take it back to Jabba, fella, I am sure they will sort it out for you at minimum of cost.

Ha! you brought it up!!
The OP asked, I answered.

As we're in agreement that he should go back to Jabba I don't see the point in going over the rest. As you say, it's well documented so if anyone wants to know more about my particular case they can do a search, start a new thread or contact me directly.
