the misses has been driving my 03 plate bora 130 sport, which had been remapped a while back. it has been cutting out on her quite a bit, as in you travel along and there is no turbo power what so ever. switch ignition off and back on again and all is good till it happens again, more on motorways than anything.
i've read it could be a number of things, but do not vag com to check, so the main problems are maf or vnt system on the turbo.
i'm just wondering how much of a pain in the ass will taking the turbo off be, i've had the exhaust off a few months ago so i know that isn't going to be seized at least, but is there enough access as i've not had a nosey at it yet, but will be having a go at removal in the morning and take off exhaust housing and give it a damn good clean.
whilst i'm at it i'll be cleaning out the EGR valve, as that's probably full of crap too.

another thing is that it's a bit smoky to say the least, now it always has been a bit and not gotten any worse really, even before it was remapped, could this be due to the other issues, or does anyone think the DPF isn't doing it's job.

any tips and hints welcome, i'm replacing rear pads tomorrow, so thought a full day on it will cure all the ailments

cheers

sticky vanes on the turbo? seems common on these, puts the car in limp mode.
i go on briskoda forum and guys on there swear by mr muscle to fix it
sounds pikey but mibbie worth a shot? Involves getting a long hose attached to a can of mr muscle then squirt it into the housing, leave for a while then run it.

 

I have a vag-com

Thanks for the link, i'll pull blower off anyhow, only take an hour or so, well within my capabilities i reckon.
I've just had front suspension off due to collapsed spring coil, then test drove it and had power loss issue, then heard metal on metal from rear brakes. Women need to learn to explain noises, discs aren't scored, but may replace anyhow. Over two years of this motor without major issue and all problems come at once

 

Sounds stupid but I know a lot of people who have done the mr muscle thing, and it's worked! If the turbo is the problem

 

Don't think it will have a dpf bud??

 

i thought it would, not looked into it though.
i have had a bit of the exhaust off, just from turbo down to main run of the system, no boxes present in there.
i will have a better look tomorrow, just lent out my 206, so down to one runner at the moment, just happens to be the E46 330ci, heavy on juice, but fun.

 

well, i got turbo out with not too much trouble, then i started stripping it....
well, not a single bolt holding the exhaust housing to the core came out without snapping or rounding off.
i chopped a few off and welded nuts onto the stubs and got three out, but two procedded to snap further down the thread. that was no biggie, had problems with these in the past on other turbos.
got down to the vnt system and only one of the bolts came out intact, these were quite fine and need to be drilled out perfectly, so with that in mind i went to my local turbo place to drill the lot out and supply new bolts
Ł60 later and all is back together, it wasn't even that sooty in my opinion, most of it blew off and only a little needed wire brushing.
will get it back together this aft and see if it has helped at all.

 

hi mate some time the vane pac can get stuck on the base of the turbine housing you some times see scores also check one vane at a time when fitted back, then fit the ring that controls the vanes after

them screws are a night mere what are they 4mm i think ,they always break

my mate had a problem with his golf cam shaft went they suffer with this and then after 10 mins of driving it would miss firer that was the injector loom ,if he let it cool down it would be fine for 10 min again weird

 

Get vagcom on it

Could be vnt actuator, camshaft, injector loom, n75 valve, maf, etc

 

well it's all back together, seems a little lazier, but then i have been tooling around in the 330 all day.
boost comes in t 2000rpm and pulls fine otherwise.
not cut out as of yet, but only gave it a bit of a run for 15mins, would usually cut out by then on the misses.
hopefully it's good for now, just need to tweak with actuator setting, bloody odd setup being vacuum operated rather than boost controlled.

 

you guessed it, turbo was sooted up, but wasn't the problem.
MAF is screwed, cutting out as much as before, very common on these.
at least i know the turbo is fine and had a good service.

 

got a reconditioned by Bosch MAF, Ł60.60 with exchange of old unit, car back running without a failure so far
at least the turbo, inlet, egr and oil line have all been cleaned out along with sorting all the niggles.

 

Sounds odd

I've got a 52 plate Passat PD130 Sport.

For whatever reason it doesn't seem to pull well at higher revs (goes ok, but a mate with a 115bhp Golf TDi thinks his is quicker).

However it picks up and pulls hard from 1100 rpm. I drove a colleagues 54 Diesel passat (think another 130 bhp model) and that felt laggy to me as it didn't pull hard until 1400 rpm.

2000 rpm would be a nightmare?

 

My passat 130pd doesn't seem that quick compared to my old 115 bora unsure if it's cos it's bigger

 

if its a good map it should pull strong from 1000rpm, un-mapped is "sluggish" under 2000rpm to save transmission wear

i must have mapped well over 100 PD golfs!

 

after changing the maf it comes into boost just under 1500rpm now.
still dies just after 4500rpm, hard to tell performance though as other wise i'm just driving my 330 and 231bhp N/A seems a fair bit quicker than a remapped 130 engine.
seems to be a lot of turbo noise, as in might be a leak somewhere, but it's running so i don't want to be messing with it as my time is precious.

 

If replacing MAF meters always always get the VW one never a cheeper copy .....

 

i used a new bosch one on exchange, so basically a new bosch one in a reused housing refurbished by bosch, Ł60.60
i think the problem with power may have been down to the clutch failing on the alternator, mainy due to the fact i know it's been going for a while and secondly it threw a fit yesterday and stopped engaging drive to alternator completely, shredded the belt and got very hot.
replaced the belt and clutch and all is good again, or at least as far as i know, the wife's driving it today, so i will see later.

 

rather then guessing at everything just stick it on a vag-com so you don't have to guess

 

i knew the turbo needed some love anyway, so i have planned to remove that and clean out the egr, just pissed me off about some seized bolts, but it should be fine for a while again.
maf was the only other concern as it was original as far as i know as i have an extensive history and it isn't in the invoices either.
vag com would be handy and i'd have popped round, but nothing i did was unnecessary.
if it was something different like running poor/bad economy i'd defo be on diagnostics to find out what was what.

 

update, it's cutting out again, the misses didn't mention it till today, but it has been doing it since yesterday
i think a vag com tool is needed, been on the bay and there is loads, but which one should i get, not after spending a fortune TBH, it's draining my life

 

Want to borrow mine?

 

possibly, if one was available that wasn't going to break the bank, it'd be a handy thing to have tucked away for the future.

 

Just put a new MAF on my brothers mk4 golf tdi, was laggy and flat, VAG com showed no faults.

 

done that already, had turbo off and ultra-sonically cleaned inside, intake manifold cleaned, egr cleaned and change MAF.
car seems to pull ok, seems to only be boosting over 1500rpm now and dies by 4k in a cloud of unburnt fuel.
actuator arm seems to move fine.

the biggest problem is the misses doesn't mention when things start to go wrong, just mentions it months down the line when it could be anything. so she's going back to petrol and i'll have the bora back for my daily.

 

Mine is a genuine one. It's only worth buying and using a genuine one. Just cover the postage and you can borrow it for a couple of weeks if it helps.

 

sounds good to me fella, i'm getting a little sick of this car now to be honest, but it is relatively cheap to run and a bit of a laugh on the straights.

 

The VAG com i have is fully licensed.

 

my mates galaxy diesel (vw 1.9 diesel) was cutting out, did some surfing and found relay 27 (109 on early models) was the problem, changed this and its been fine, has cut out once or twice, but generally changing it sorted the cutting out. we didn't use a genuine replacement relay, but mark_24v_wiring off here wired in a normal 4 pin relay, so replacing with a genuine may well sort completely, we just tight bastards and the 4 pin was cheaper.

 

Where abouts are you fella?
It could something as simple as a relay, but i think it's time for some diagnosis tools.

 

you need to get some live data readings off it whilst driving and when it cuts out should be simple to find the fault then, my moneys on cam sensor tho

 

the relay that fails is the relay that supplies power to the ECU, so when it cuts the ECU will shut down, so anything connected to it will just think its been turned off, so no code, i had something plugged in when it had cut out, and couldn't talk to ECU because the ECU had no power

 

don't suppose you have vag com and fancy a drive?

 

For all the aggro it's giving you, do you not know anyone with a fault code reader? Would save a lot of pissing about.

 

Who remapped the car?

Sounds absolutely characteristic of an overboosting problem. If the ECU detects an abnormally high boost pressure (not uncommon with a remap) it will disable the boost control and effectively turn off the turbo. A key cycle resets the ECU and it will work again until the next time.

 

the car was remapped two years ago (four days after i bought it), it's been the last six months that it is regularly cutting out on motorway runs.
doesn't tend to do it round town though.
it is more of a case when not accelerating, rather when it's cruising or very gentle throttle.

DanW, exactly what i'm now aiming for since i've done all the maintenance common fault finding so far.

 

Pm me your address and il pop it in the post tomorrow fella

 

I had a fault on mine where loading the car in sixth uphill on the motorway would stick the car into limp mode. Puzzled me for a while and turned out to be a split boost pipe.

And yesterday mine just cut out, would only crank and not fire, but brought no errors up. I'm thinking in tank pump - lets see! This is a BKD.

Nearly forgot about the intake manifold flap, that went last month too. Think I need to clue myself up on deleting the EGR, the gunk inside was horrendous.
